The first time I made these Chocolate Peppermint Sandwich Cookies, I knew they were going to become one of my favorite holiday treats. They have that rich, deep chocolate flavor that feels a little indulgent, but the cool peppermint filling keeps every bite bright and festive. They look impressive stacked on a cookie tray, yet they are surprisingly simple to pull together.

What I love most is the contrast in every bite. The cookies are soft and fudgy, almost like little brownie cookies, while the pink peppermint filling is creamy, fluffy, and just the right amount of sweet. A few crushed candy canes around the edges make them extra pretty and add that unmistakable holiday crunch.

Why You’ll Love These Chocolate Peppermint Sandwich Cookies

I love making these cookies when I want something that feels bakery-worthy without a complicated process. The chocolate cookie layers stay soft, the filling is easy to mix, and the finished sandwich cookies hold up beautifully for parties, cookie boxes, and make-ahead holiday baking.

They are also perfect when I want a dessert that stands out on a holiday table. The dark chocolate cookies, blush-pink filling, and bits of peppermint candy make them festive enough for Christmas dessert platters, homemade gift boxes, or a cozy weekend baking project.

What Kind of Peppermint Should I Use in Chocolate Peppermint Sandwich Cookies?

I like using peppermint extract in the filling because it gives the cleanest mint flavor without adding any extra texture. A little goes a long way, so I start small and taste as I go. For the decorative crunch around the edges, crushed candy canes or peppermint candies work perfectly.

If you want a smoother filling, you can keep the peppermint candy only on the outside of the cookies. That way, the center stays velvety while still giving you that classic holiday peppermint finish on every bite.

Ingredients for the Chocolate Peppermint Sandwich Cookies

The ingredient list is simple, but each one plays an important role in creating that rich chocolate cookie and creamy peppermint center.

All-purpose flour gives the cookies structure so they stay tender but sturdy enough for sandwiching.

Unsweetened cocoa powder is what gives these cookies their deep chocolate flavor and dark color.

Baking soda helps the cookies spread just enough while keeping them soft in the middle.

Salt balances the sweetness and makes the chocolate flavor taste fuller.

Unsalted butter adds richness to both the cookies and the filling.

Brown sugar brings moisture and a soft, chewy texture to the cookies.

Granulated sugar sweetens the dough and helps create a balanced cookie texture.

Eggs bind the dough together and add richness.

Vanilla extract rounds out the chocolate flavor and makes the cookies taste warmer and more layered.

Powdered sugar creates a smooth, fluffy filling with just the right sweetness.

Peppermint extract gives the filling that classic cool holiday flavor.

Heavy cream or milk loosens the filling just enough so it spreads easily.

Pink food coloring is optional, but I love it for that festive peppermint look.

Crushed candy canes or peppermint candies add crunch and make the edges look extra pretty.

Mini chocolate chips are optional on top, but they make a cute finishing touch.

How To Make the Chocolate Peppermint Sandwich Cookies

Making these cookies is easier than they look, and I like breaking the process into a few simple steps so everything stays manageable.

Step 1: Mix the dry ingredients

In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. I like to do this first so the cocoa is evenly distributed and the dough mixes together smoothly later.

Step 2: Cream the butter and sugars

In a large mixing bowl, beat the butter, brown sugar, and granulated sugar until the mixture looks light and fluffy. This step helps create a soft cookie texture, so I do not rush it.

Step 3: Add the eggs and vanilla

Beat in the eggs one at a time, then add the vanilla extract. The dough should look glossy and well combined at this point.

Step 4: Combine the wet and dry mixtures

Gradually add the dry ingredients to the wet ingredients, mixing just until a thick chocolate dough forms. I stop as soon as I no longer see dry streaks so the cookies stay tender.

Step 5: Scoop and bake

Scoop the dough into even portions and place them on a parchment-lined baking sheet, leaving room for spreading. Bake until the cookies are set around the edges but still soft in the centers. Let them cool completely before filling.

Step 6: Make the peppermint filling

Beat the butter until smooth, then mix in the powdered sugar, peppermint extract, and a splash of cream or milk. Add a tiny bit of pink food coloring if you want that classic holiday color. The filling should be fluffy and spreadable.

Step 7: Assemble the sandwich cookies

Match the cookies in pairs by size. Spread or pipe the peppermint filling onto the flat side of one cookie, then top with another cookie. Gently roll the filling edges in crushed candy canes if you want extra texture and color.

Step 8: Finish and chill

I like to let the assembled cookies chill for 15 to 20 minutes so the filling firms up slightly. That makes them easier to serve and gives the flavors time to come together.

Serving and Storing Chocolate Peppermint Sandwich Cookies

These cookies are rich enough to feel special, so I usually serve them on a holiday dessert tray with coffee, hot cocoa, or cold milk. They also make a beautiful addition to cookie boxes because they look festive and hold their shape well.

This recipe feeds about 12 people, depending on whether everyone has one or two sandwich cookies. Store them in an airtight container in the refrigerator for up to 5 days. I like letting them sit at room temperature for a few minutes before serving so the filling softens slightly. For longer storage, you can freeze them in a single layer and thaw them in the fridge.

What to Serve With Chocolate Peppermint Sandwich Cookies?

These cookies pair so well with other holiday desserts and cozy drinks, especially when I want to build a festive dessert spread.

Hot chocolate is my favorite pairing because the creamy warmth brings out the rich cocoa flavor in the cookies.

Coffee or peppermint mocha balances the sweetness and makes these cookies feel even more bakery-style.

Vanilla ice cream turns them into an extra indulgent plated dessert.

A holiday dessert tray with treats like candy cane cheesecake parfaits, quick Christmas peppermint pie, easy mint chocolate chip snowball cookies, and chocolate chip snowball cookies makes these sandwich cookies feel right at home.

Frequently Asked Questions

Can I make the cookies ahead of time?

Yes, and I actually think they are a great make-ahead dessert. You can bake the cookies a day or two in advance and store them in an airtight container. The filling can also be made ahead and chilled, then softened slightly before assembling.

Do I have to use pink food coloring in the filling?

Not at all. The food coloring is only for appearance. The filling tastes just as good without it, so you can leave it plain if you want a more classic peppermint cream look.

Can I freeze Chocolate Peppermint Sandwich Cookies?

Yes, these freeze very well. I like to place them on a tray until firm, then transfer them to a freezer-safe container with parchment between layers. Thaw them in the refrigerator so the filling stays nice and neat.

What if I do not have peppermint extract?

If you skip peppermint extract, the cookies will still be delicious, but they will taste more like chocolate sandwich cookies with vanilla cream. Peppermint extract gives the filling its signature holiday flavor, so I recommend using it if you can.

How do I keep the cookies soft instead of dry?

The biggest trick is not overbaking them. I pull them from the oven when the edges look set but the centers still seem a little soft. They continue to firm up as they cool, which helps keep that tender brownie-like texture.
