Stop scrolling for a second. You know that feeling when you bite into a nostalgic oatmeal cream pie, but you wish it had a little more… oomph? That is exactly what we are doing here today! These Eggnog Oatmeal Cream Pies are not just cookies; they are a festive obsession waiting to happen.
Baking is love made edible,” as they say, and this recipe is pure holiday romance. I recently brought a batch of these to a neighborhood potluck, and let me tell you—the platter was empty in ten minutes flat! We are taking soft, chewy, spice-laden oatmeal cookies and sandwiching them around a rich, boozy (or not!) eggnog filling. It’s creamy. It’s spiced. It’s absolutely ridiculous. Let’s get baking!

Why These Spiced Cream Pies Will Be Your New Favorite Tradition
Listen, I have been through the holiday baking wringer more times than I care to admit. There was the year I forgot the sugar in the pumpkin pie, and let’s not talk about the “rock hard” gingerbread incident of 2015. But when I finally nailed these eggnog oatmeal cream pies, everything changed. It felt like I finally cracked the code on Christmas desserts.
You know how sometimes you grab a cookie from a holiday tray and it’s just… meh? It’s dry, or it crumbles into dust on your sweater. That is the worst. I wanted something that felt like a hug. That is why these spiced cream pies are going to be your new go-to. They aren’t just cookies; they are a whole experience.
It’s All About That Texture
Let’s be real for a second. The texture is what makes or breaks a sandwich cookie. I remember trying to make these with crisp cookies once, and the filling squished out everywhere. It was a disaster! You need that specific, soft resistance.
When you bite into these chewy oatmeal cookies, your teeth sink right into the soft center before hitting that fluffy spiced buttercream frosting. It is incredibly satisfying. The contrast between the dense, molasses-rich cookie and the light, airy filling is just magic. It reminds me of those little snack cakes we used to trade in the school cafeteria, but way better because you made them yourself.
A Flavor Explosion (Without Being Too Much)
I used to think eggnog was kind of gross, to be honest. Drinking a glass of it? No thanks. But baking with it? That is a different story. The flavor in these eggnog oatmeal cream pies is subtle but distinct. You get the warmth from the cinnamon and cloves in the cookie, and then that creamy, sweet kick from the filling.
If you are worried about them being “too boozy” or strong, don’t be. The spices mellow everything out. My neighbor, who claims she hates eggnog, ate three of these at our block party last year. I didn’t have the heart to tell her what was in them until she was licking the crumbs off her fingers!
Totally Customizable for Your Crew
Another reason I am obsessed with this recipe is that it is forgiving. Baking can be so strict, right? If you mess up one thing, the whole science project fails. But here, you have some wiggle room.
- Spice lover? Add extra nutmeg to the filling.
- Hate cloves? Leave them out!
- Gluten-free friends? I have swapped in 1-to-1 GF flour, and they still taste amazing.
I have learned that the best holiday cookie recipes are the ones you can tweak to fit your family. You don’t need to be a professional pastry chef to pull this off. Just follow the steps, keep an eye on the oven, and trust your gut.
The Nostalgia Factor is Real
There is something about an oatmeal cookie that just feels right in the winter. It brings back memories of grandma’s kitchen, even if your grandma actually just bought cookies from the store (mine totally did). These homemade little debbie copycat treats tap into that nostalgia but elevate it.
When you put a platter of these out, people’s eyes light up. They look impressive, like you spent all day slaving away, but honestly? Once you get the rhythm down, they are pretty simple. Just don’t rush the cooling process—I learned that the hard way when my filling melted into a sad puddle. Patience is key, folks!

Gathering the Essential Ingredients for Eggnog Oatmeal Cookies
Alright, class is in session! Before we even think about turning on that oven, we need to talk groceries. I cannot tell you how many times I have ruined a perfectly good batch of eggnog oatmeal cookies because I thought I could swap ingredients willy-nilly. It doesn’t work like that. Baking is science, but it’s also about knowing your materials.+1
When I first started baking these, I grabbed whatever was in my pantry. The result? A sad, flat mess that didn’t taste anything like Christmas. So, grab a pen (or just screenshot this), because getting the specific ingredients right is half the battle.+1
The Great Oat Debate: Old-Fashioned vs. Quick
Here is where most people mess up. You are standing in the cereal aisle, staring at the canisters. Do not, I repeat, do not buy the “quick cooking” or “instant” oats. I used those once because they were on sale, and my cookies turned into dry, powdery hockey pucks. It was embarrassing.+1
You need old-fashioned rolled oats. They are thicker and they hold their shape better in the oven. They give the cookie that signature chewiness we are looking for. The quick oats just dissolve into the dough and you lose all that lovely texture. We want a hearty bite here, not oatmeal mush.+1
Dealing with the Molasses
I know, I know. Molasses is a pain to work with. It is sticky, it smells strong, and it gets everywhere. But please don’t skip it or try to use honey instead. Dark molasses provides that deep, rich color and moisture that makes these cookies soft.+1
Here is a little trick I learned after getting molasses stuck to my measuring spoon for the hundredth time: spray your measuring spoon with a little non-stick cooking spray before you pour. The molasses slides right out! It’s a total game changer. Just make sure you get the unsulphured kind found in the baking aisle, not the bitter blackstrap stuff.+1
Spices: The Heart of the Flavor
If we are making holiday cookie recipes, we can’t be shy with the spices. This is supposed to taste like eggnog, right? That means you need nutmeg. A lot of it.
If you have a jar of ground nutmeg that has been sitting in your cupboard since 2018, throw it out. Seriously. Go buy a whole nutmeg nut and grate it fresh. The flavor difference is insane. It adds that spicy, warm kick that cuts through the sugar. We are also using plenty of cinnamon and a hint of cloves to round it out. It smells like heaven when it hits the heat.
The Butter Situation
We need to talk about temperature. Your unsalted butter needs to be at room temperature. Not melted, and not rock hard from the fridge. If it is melted, your cookies will spread across the pan and merge into one giant, greasy mega-cookie. I have been there, and while it tastes okay, it looks terrible.
If you push the butter with your finger, it should leave a dent but not be greasy. That is the sweet spot. Also, stick to real butter here; shortening just doesn’t give the same flavor for a high-quality Christmas baking idea.

Mastering the Chewy Oatmeal Cookie Base
Okay, let’s get our hands dirty. Well, ideally, let the mixer do the work so we don’t have to. The base of these eggnog oatmeal cream pies is, obviously, the cookie. If the cookie is too hard, the filling squishes out the sides when you bite down. If it’s too soft, the whole thing falls apart in your hand. We need that perfect middle ground.
I remember the first time I tried to make chewy oatmeal cookies from scratch. I just dumped everything into the bowl at once like I was making a soup. Big mistake. The texture was weirdly tough, and I was so disappointed. I learned that the order you add things actually matters a lot.
The Creaming Step You Can’t Skip
You gotta start by beating the butter and sugars together until they look pale and fluffy. I use my stand mixer for this, but a hand mixer works too. I usually let it run for about 3 to 4 minutes. It feels like a long time when you are just standing there watching butter spin, but trust me on this.
You are whipping air into the dough. This is what gives soft baked oatmeal cookies that nice lift so they aren’t dense bricks. We are using mostly brown sugar here. Brown sugar oatmeal cookies are superior because the extra moisture keeps them chewy for days. If you rush this part, your cookies will be flat and greasy.
The Hardest Part: Waiting
Here is the part where I usually get impatient and frustrated. You have to chill the dough. I know! It is so annoying when you just want to bake and eat. But listen to me. I tried skipping this step once because I was running late for a party.
The cookies spread out so thin they looked like lace doilies. They were a hot mess. The oats need time to soak up the moisture, and the butter needs to firm up again. So, cover the bowl and put it in the fridge for at least 30 minutes. Go fold some laundry or scroll on your phone while you wait.
Scooping for Success
Since we are making sandwiches, the cookies need to be the same size. You don’t want a giant top cookie and a tiny bottom cookie. It just looks sloppy. I always use a cookie scoop to measure the dough.
A medium cookie scoop size (about 1.5 tablespoons) is perfect for these. It makes sure every single cookie is identical. Plus, it is so much faster than using two spoons. I like to bake these on a silpat baking mat because nothing sticks to it, and it keeps the bottoms from getting too dark.
Eyes on the Oven
Baking these is a little tricky because it happens fast. You are looking for golden brown edges, but the center should still look a little wet and underdone. In my oven, that takes exactly 11 minutes.
If they look fully cooked in the oven, they will be hard as rocks when they cool down. We don’t want crunchy cookies here! Take them out while they still look too soft. Let them sit on the hot pan for 5 minutes to firm up, then move them to a wire cooling rack. If you try to move them too soon, they will break. Then you have to eat the broken ones to hide the evidence. Actually, that’s not a bad thing!

Whipping Up the Fluffy Eggnog Buttercream Filling
Now we get to the fun part. The filling. Honestly, the cookie is just the vehicle for this frosting, right? This isn’t just regular frosting; it’s a creamy filling recipe that tastes exactly like a glass of holiday cheer. But I will be honest with you, buttercream used to scare me.
I remember one year I tried to make a fancy holiday cake, and my frosting broke. It looked like curdled milk. I sat on the kitchen floor and cried. It was not my finest moment. But I learned that temperature is everything when it comes to spiced buttercream frosting. If you master the temperature, you master the frosting.
The Butter Battle
Your butter cannot be melted. I repeat, put the microwave away! If your butter is too soft, your filling will be soup. It needs to be cool room temperature. You should be able to press your thumb into it and leave a mark, but it shouldn’t feel greasy.
I usually take my butter out of the fridge about an hour before I start. If your kitchen is hot (like mine gets when the oven is on), keep an eye on it. If the butter is too warm, the fluffy frosting tips won’t hold their shape, and your sandwich cookies will slide apart. It is super frustrating when that happens.
Getting the Eggnog Flavor Right
Here is the tricky part about baking with eggnog. It is a liquid. Buttercream hates liquid. If you pour too much in, the whole thing separates. I used to just dump half a cup in and wonder why it turned into a puddle.
To get that strong flavor without ruining the texture, you have a couple of options. You can use a really high-quality, thick eggnog. Or, you can use a tiny bit of rum extract or brandy extract to boost the flavor. I also like to use vanilla bean paste instead of extract because those little black specks look so fancy in the white cream. It makes it look like you bought them at a bakery.
Taming the Sweetness
American buttercream is basically just butter and powdered sugar, so it can get sweet fast. Like, tooth-aching sweet. Since our cookies are already sweet with molasses and brown sugar, we need to balance the filling.
I always add a generous pinch of salt to the frosting. It sounds weird, but it cuts the sugar. And don’t forget the spices! I grate fresh nutmeg right into the bowl. This nutmeg spiced filling is what ties the whole dessert together. Taste as you go. If it’s too sweet, add a little more salt or spice. You are the boss of the bowl.
Piping Like a Pro (Or Faking It)
You could just use a knife to smear the frosting on, but we want these to look pretty, right? I am terrible at cake decorating, but piping these is actually easy. You don’t need fancy skills.
I throw the frosting into a disposable piping bag with a big round tip. If you don’t have one, just use a ziplock bag and cut the corner off! I have done that plenty of times. Pipe a big swirl in the center of the bottom cookie, leaving a little room at the edge. When you press the top cookie down, the piping buttercream spreads out perfectly to the sides. It is so satisfying to squash them together!

Assembly, Storage, and Freezing Tips
Okay, friends, we are in the home stretch! This is where it all comes together. But I have to give you a serious warning: do not rush this part. I know the cookies smell amazing, and you want to eat them immediately. But if you try to frost a warm cookie, you are going to have a bad time.
I learned this lesson the hard way (as usual). I was in a hurry to get to a holiday party, and I piped my beautiful filling onto cookies that were still slightly warm. By the time I got to the party, the filling had melted and slid right off. It looked like a crime scene. So, take a deep breath and let’s do this right.
The Waiting Game: Cooling Down
Your cookies need to be 100% cool. Not “kinda cool,” not “lukewarm.” Stone cold. I usually let mine sit on the wire cooling rack for at least an hour. If you touch the bottom of the cookie and it feels even a tiny bit warm, walk away.
While you wait, you can clean up the kitchen or maybe sample a little bit of that frosting. You know, for quality control. It is important work! Once they are cool, match them up in pairs so you have a top and a bottom that fit together nicely.
The “Squish” Technique
When you are ready to assemble, pipe or spread a dollop of filling on the bottom cookie. Then, take the top cookie and gently press it down. I call this the “squish test.” You want to press just hard enough to push the filling to the edges, but not so hard that you break the cookie.
These sandwich cookies recipe results are pretty sturdy, but they aren’t bricks. Treat them with a little kindness. If the filling oozes out too much, just run a clean finger (or a knife) around the edge to smooth it out.
Why the Fridge is Your Best Friend
Here is a secret: these cookies actually taste better the next day. I know, it sounds crazy. But when you store them in the fridge, the moisture from the filling seeps into the cookie. They get softer and the flavors meld together. It becomes this incredible old fashioned oatmeal pies texture that you just can’t get fresh out of the oven.
I store mine in an airtight container in the refrigerator. They stay good for about 5 days, but let’s be honest, they never last that long in my house. My kids usually hunt them down within 48 hours.
Freezing for Later (If You Have Willpower)
If you are super organized and doing make ahead christmas cookies, these freeze beautifully. Wrap each pie individually in plastic wrap, then put them all in a big freezer bag. They will keep for up to 3 months.
When you want to eat one, just pull it out and let it sit on the counter for 15 minutes. Or eat it frozen. Seriously, don’t knock it until you try it. It tastes like an ice cream sandwich! It is one of my favorite freezable holiday desserts hacks.

Well, there you have it! We have successfully navigated (oops, I mean “gotten through”) the world of Eggnog Oatmeal Cream Pies. I really hope this recipe brings a little bit of extra joy to your holiday season. It is one of those special treats that looks fancy but is actually just a big bowl of comfort.+2
If you make these, please don’t be hard on yourself if they aren’t perfect the first time. The “ugly” ones still taste delicious! Baking is about having fun and feeding the people you love.
