These sandwiched cake cookies actually have nothing to do with pie. In fact, they seem more closely related to cupcakes, and their frosting-like filling makes them simple and easy to eat!
- Prep time 40 minutes
- Cooking time 15 minutes
- Total time 55 minutes
- 1 3/4 cup all-purpose flour
- 1 cup granulated sugar
- 3/4 cups Dutch process cocoa powder
- 1/2 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup cool unsalted butter , cut into pieces
- 1 large egg
- 3/4 cups milk , at room temperature
- 1/2 cup sour cream
- 2 teaspoons pure vanilla extract
- 1 cup unsalted butter , at room temperature
- 1 cup pure, smooth peanut butter
- 2 cups icing sugar , sifted
- 1 teaspoon pure vanilla extract
1. Preheat the oven to 375°F. Line two baking trays with parchment paper. Place the trays in the oven to warm right before making the cookie dough (this step will help the cookies bake with smooth curved tops).
2. For the cookies, sift the flour, sugar, cocoa powder, baking powder, baking soda, and salt into a large mixing bowl or the bowl of a stand mixer fitted with the paddle attachment. Add the butter and mix on medium-low speed to cut it in until the pieces are barely visible.
3. In a separate bowl, whisk together the egg, milk, sour cream, and vanilla. Add to the flour mixture and mix on low speed to incorporate then increase to medium-high and beat for about 2 minutes, until the batter is fluffy and holds its structure. Use a medium ice cream scoop to scoop out 16–20 portions onto the now-hot, prepared baking trays, leaving 3 inches between them. Bake the "pies" for about 15 minutes, until the tops spring back when gently pressed. Cool the "pies" on the baking trays before filling.
4. For the filling, beat the butter to lighten it and then beat in the peanut butter. Add 1 cup of the icing sugar and beat in. Stir in the vanilla and then beat in the remaining 1 cup of icing sugar until fluffy. Fill a piping bag fitted with a large star tip, pipe filling onto one of the "pies," and top with a second "pie," pressing gently. Repeat with the remaining pies. They will keep in an airtight container, or on a plate covered in plastic wrap, for up to 3 days—no need to refrigerate.
Makes 8 to 10 large whoopie pies.
