Ingredients
Scale
Cookie Dough
- 1 1/2 cups (195g) all-purpose flour
- 3/4 tsp baking soda
- 1/2 tsp salt
- 1/2 cup (112g) unsalted butter, room temperature
- 1/2 cup (140g) peanut butter
- 1/2 cup (104g) granulated sugar
- 1/2 cup (112g) packed light brown sugar
- 1 large egg
- 1 tsp vanilla extract
- 1/2 cup (80g) chopped peanut butter cups (4–5 full-sized Reese’s)
- 3/4 cup (127g) semi-sweet chocolate chips
Buttercream Frosting
- 1/2 cup (112g) unsalted butter, room temperature
- 2 cups (260g) powdered sugar
- 1/4 cup (29g) natural unsweetened cocoa powder
- 1/2 tsp vanilla extract
- 1–2 tbsp heavy whipping cream
- 4–5 full-sized Reese’s, cut in half, for decoration
Instructions
- Preheat and prepare pan: Preheat your oven to 350°F (180°C). Line a 9-inch cake pan with parchment paper on the bottom and spray the sides with baking spray to ensure easy removal later. Set aside.
- Mix dry ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set this mixture aside.
- Cream butter, peanut butter, and sugars: In a large mixer bowl, beat the unsalted butter, peanut butter, granulated sugar, and brown sugar on medium speed until light, fluffy, and pale in color, about 2-3 minutes. Be sure to scrape the bowl sides occasionally for even mixing.
- Add egg and vanilla: Incorporate the egg and vanilla extract into the creamed mixture and mix until fully combined.
- Combine with dry ingredients: Gradually add the flour mixture to the wet ingredients, mixing just until dough forms. Avoid over mixing to maintain a tender texture.
- Fold in mix-ins: Gently stir in the chopped Reese’s peanut butter cups and semi-sweet chocolate chips until evenly distributed through the dough.
- Shape and bake: Press the cookie dough evenly into the prepared cake pan. You can press additional chocolate chips or chopped Reese’s onto the surface for extra flavor and decoration. Bake for 18-22 minutes or until the edges are golden and the center is set but still soft.
- Cool the cookie cake: Remove from the oven and let the cookie cake cool completely in the pan. Once cooled, flip it onto a cooling rack, place another rack on top, and flip again to reveal the right side up for serving.
- Make the buttercream frosting: In a large bowl, beat the butter until smooth. Add 1 cup of powdered sugar and beat until combined. Next, add the cocoa powder and vanilla extract and mix thoroughly. Add 1 tablespoon of heavy cream and beat to combine.
- Finish buttercream: Mix in the remaining powdered sugar and beat until smooth and fluffy. Add the additional tablespoon of cream if needed to reach a spreadable consistency.
- Decorate: Pipe the buttercream evenly around the edges of the cookie cake and place halved Reese’s cups between the buttercream swirls for a beautiful and tasty garnish.
- Storage and serving: Store the cookie cake in an airtight container. It can be kept at room temperature for up to 2 days, then refrigerate because of the buttercream. Serve at room temperature and consume within 4-5 days for the best taste and texture.
Notes
- Ensure the cookie cake is completely cool before applying buttercream to avoid melting or sliding.
- Do not overmix the dough to maintain a soft, chewy texture.
- If desired, substitute peanut butter cups with another peanut butter chocolate candy.
- You can adjust the amount of heavy cream in the buttercream for desired consistency.
- Store leftover cookie cake in the refrigerator due to the buttercream frosting.
