Whoopie Pies are giant bakery style chocolate cookies with a delicious, light, and fluffy icing in the center. Every bite is a party in your mouth!
- 2 cups all-purpose flour
- ½ cup dutch-processed cocoa powder
- 1 teaspoon baking soda
- ½ teaspoon salt
- 8 tablespoons unsalted butter, softened
- 1 cup packed brown sugar
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1 cup buttermilk
- 12 tablespoons unsalted butter, softened
- 1 ¼ cups confectioners’ sugar
- 1 ½ teaspoons vanilla extract
- ⅛ teaspoon salt
- 2 ½ cups marshmallow creme
For the Cakes:
- Adjust oven racks to upper-middle and lower-middle positions and preheat oven to 350℉.
- Line 2 baking sheets with parchment paper.
- Whisk flour, cocoa, baking soda, and salt together in a bowl.
- Using a stand mixer with a paddle, beat butter and sugar about 3 minutes until fluffy.
- Add egg and beat until incorporated.
- Add vanilla and mix on medium speed, scraping sides of the bowl as needed.
- Reduce speed to low and add flour in 3 additions, alternating with buttermilk in 2 additions. Stir batter by hand to ensure no flour pockets remain.
- Using a ⅓-cup measuring cup, scoop 6 mounds of batter onto each baking sheet (about 3 inches apart), making 12 mounds total. Bake 15 to 18 minutes, rotating sheets halfway through baking, until centers spring back when lightly pressed.
- Let cakes cool completely on sheets.
For the Filling:
- Using a stand mixer with a paddle, beat butter and sugar for about 3 minutes, until fluffy. Add vanilla and salt and mix. Add marshmallow creme and mix for about 2 minutes until combined. Refrigerate for 30 minutes.
- Place ⅓ cup of filling on the bottom half of cakes, then top with remaining cakes. Press together to spread the filling to the edge. Serve.
- You can make around 24 whoopie pies that are the size of a traditional cookie by placing 1 rounded tablespoon of batter on your prepared sheets and baking the cookies for around 10 minutes. These are giant!
