What Kind of Cocoa Powder Should I Use?

For rich, deep chocolate flavor, use unsweetened Dutch-processed cocoa powder. It gives the cookies their signature dark color and smooth texture. If you only have natural cocoa powder, it will still work, but the flavor may be slightly more acidic and the cookies lighter in color.

How To Make the Chocolate Peppermint Sandwich Cookies

Step 1: Cream the Butter and Sugars

In a large mixing bowl, beat together 1 cup unsalted butter, 3/4 cup brown sugar, and 1/2 cup granulated sugar until fluffy and creamy—about 2-3 minutes.

Step 2: Add the Wet Ingredients

Add 2 large eggs, one at a time, beating well after each addition. Mix in 1 teaspoon vanilla extract.

Step 3: Combine the Dry Ingredients

In a separate bowl, whisk together 2 cups all-purpose flour, 3/4 cup Dutch-processed cocoa powder, 1 teaspoon baking soda, and 1/2 teaspoon salt.

Step 4: Mix and Chill the Dough

Gradually add the dry mixture to the wet ingredients and mix until just combined. Cover and chill the dough for at least 1 hour.

Step 5: Bake the Cookies

Preheat your oven to 350°F (175°C). Scoop tablespoon-sized portions and roll them into balls. Place on a parchment-lined baking sheet, spacing 2 inches apart. Bake for 9-10 minutes until edges are set. Let cool completely.

Step 6: Make the Peppermint Buttercream

In a medium bowl, beat 1/2 cup unsalted butter until fluffy. Add 1 1/2 cups powdered sugar, 1/2 teaspoon peppermint extract, and 1 tablespoon milk or cream. Beat until smooth and creamy.

Step 7: Assemble the Sandwiches

Spread or pipe about 1 tablespoon of the peppermint buttercream on the flat side of half the cookies. Top with the remaining cookies to form sandwiches. Roll the edges in crushed peppermint candies if desired.

How to Store Chocolate Peppermint Sandwich Cookies

Store assembled cookies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to a week. You can also freeze the cookies (with or without filling) for up to 2 months—just let them come to room temperature before serving.

To freeze, place in a single layer on a baking sheet until firm, then transfer to freezer-safe bags. If freezing filled cookies, separate layers with wax paper.

Frequently Asked Questions

Can I use natural cocoa powder instead of Dutch-processed?
Yes, but the flavor will be slightly more acidic and the color lighter. Dutch-processed cocoa gives a richer, deeper chocolate note.

Can I freeze the cookie dough?
Absolutely. Scoop the dough into balls, freeze on a tray, and then store in a zip-top bag. Bake from frozen, just add 1-2 minutes to baking time.

How strong is the peppermint flavor?
The peppermint is present but not overpowering. You can increase or decrease the extract to taste, but stick with peppermint extract, not mint or spearmint.

What can I use instead of peppermint candies on the edge?
Crushed chocolate chips, holiday sprinkles, or even sanding sugar all work great and add a festive touch.

Can I make them gluten-free?
Yes! Use a 1:1 gluten-free all-purpose flour substitute. Make sure your peppermint extract and candies are gluten-free too.
