Chocolate Peppermint Whoopie Pie Overview

Whoopie pies are literally cake in cookie form! The cookie part is a thick cake batter cooked into little cookies and the filling is typically buttercream frosting. 

For our chocolate peppermint whoopie pies we are making a thick chocolate cake batter to bake into cookies. The turn out fluffy and moist and then we fill them with a simple american buttercream flavored with a hint of peppermint! 

How to Make Chocolate Peppermint Whoopie Pies

The mixing method for the cookie part of these chocolate whoopie pies is the creaming method for cakes. This method is a bit different than the creaming method for cookies, but the batter for the cookies is a thick cake batter rather a cookie dough. 

Step 1: Mix Together the Dry Ingredients

For this mixing method, you want to start by mixing together the dry ingredients and the wet ingredients separately. The cocoa powder in these cookies can be either dutch processed or natural cocoa powder. I like to use natural cocoa powder for a more rich chocolate flavor. 

Step 2: Mix Together the Wet Ingredients

The wet ingredients in a liquid measuring cup after being stirred together.

Mix together the wet ingredients, except the eggs, together separately. We are using buttermilk and coffee as our wet ingredients. The cookies will not taste like coffee, rather it will make the cookies have a more intense chocolate flavor. 

Step 3: Cream the Butter and Sugar Together + Add Eggs

Next, we are going cream together the butter and sugar until light and fluffy. It is important that the butter is at room temperature to do this properly.

After the butter and sugar is really fluffy, you can mix in the egg and vanilla extract. 

Step 4: Alternate Adding Dry & Wet Ingredients

For the last part of mixing, you want to alternate adding in the dry and wet ingredients. This is because the creamed butter and sugar cannot absorb a lot of liquid at once. So we add a little dry, then some wet, then more dry, then wet, and so on. This creates the lightest cake batter. 

Start with one third of the dry ingredients and mix in. Then add half of the wet ingredients and mix that in. Then add a second third of the dry, followed by the rest of the wet, then end with the rest of the dry.

Your batter should look nice and smooth after you are done. If the batter looks broken with fat and liquid separating, you can still bake it and it will be fine. But it means that the ingredients weren’t incorporated properly and the cookies might not be as tender and fluffy. 

Step 5: Scoop & Bake

Scoop about 1 TBSP of batter for each cookie on parchment lined baking sheets and allow room for some spreading.

I like to bake the cookies almost all the way through and then pull them out and add the peppermint pieces on top and then let them finish baking. If you add them at the beginning they will melt into the cookie. 

Step 6: Fill the Whoopie Pies with Peppermint Buttercream

Fill the cooled cookies with the peppermint buttercream and press two halves together. Store the cookies wrapped in the refrigerator. An airtight container will cause them to become soggy.

  4. With the mixer on low speed, alternate adding the flour mixture in three additions and buttermilk/coffee mixture, in two additions, beginning and ending with the flour.
  5. Drop heaping tablespoons (preferably using a small ice cream scoop) of the batter onto the prepared baking sheets, spacing about 2 inches apart. Smooth the tops of the cookies with moistened fingers if needed.
  6. Bake at 375 (190 C) for 4 minutes, then take out and sprinkle peppermint pieces on top of half of the cookies if desired. Bake for 1-3 more minutes.
  7. Remove from oven and transfer to a wire rack to cool completely.

  1. Thank you! I am really trying to improve my pictures. It can be difficult.

    I’ll have to go check out your whoopie pies. LOVE SALTED CARAMEL!

  2. Beautiful pictures! I love your comparison of whoopie pies and macarons. Whoopie pies are so American, they are big and sloppy and overdone, but sometimes just exactly what you need! I just posted a recipe for salted caramel whoopie pies which were delicious, but I had to promptly bring them all into work for people to devour. I love how pretty the peppermint filling looks in these. Thanks for sharing!

  3. You have the most beautiful blog!

  4. or try Duncan Hines cake mix – follow the instructions on the website:

    I’m no photographer, but they were great. I like scratch too, but when I can buy the cake mix AND a can of frosting for less that the ingredients to go scratch, I go with the cake mix.

  5. your photos are beautiful!

  8. You didn't list corn syrup in the ingredients but the instructions say to drizzle it in (in the filling preparation).

  9. I didn’t see corn syrup in the filling ingredients, but it is in the procedures. Is it supposed to be in this recipe?

  10. Wow. This is a really old post and I never noticed that before. Thanks for bringing it to my attention. I am almost 100% sure that it is 1/2 cup of light corn syrup. I haven't made this recipe in almost 2 years, but I looked at the recipe that I adapted it from and that seems correct.
