Ingredients
Cookie Base
- ½ cup butter, softened
- ½ cup creamy peanut butter
- ½ cup brown sugar
- ¼ cup granulated sugar
- 1 large egg
- 1 tsp vanilla extract
- 1 cup all-purpose flour
- ½ tsp baking soda
- ¼ tsp salt
Peanut Butter Filling
- ½ cup creamy peanut butter
- ¼ cup powdered sugar
- 1 tbsp butter, softened
Chocolate Ganache
- 1 cup sugar-free or semisweet chocolate chips
- 2 tbsp heavy cream
Instructions
- Preheat and Prepare Pan: Preheat oven to 350°F / 175°C. Line a round cake pan (8–9 inch) with parchment paper to prevent sticking.
- Make Cookie Dough: Beat butter, creamy peanut butter, brown sugar, and granulated sugar together until smooth and creamy for the cookie base.
- Add Egg and Vanilla: Mix in the egg and vanilla extract thoroughly to incorporate moisture and flavor.
- Combine Dry Ingredients: Add the all-purpose flour, baking soda, and salt to the wet mixture and stir until a soft dough forms.
- Bake the Cookie: Press the dough evenly into the prepared pan. Bake for 15–18 minutes until the edges are lightly golden. Remove from oven and allow the cookie base to cool completely before proceeding.
- Prepare Peanut Butter Filling: In a bowl, mix creamy peanut butter, powdered sugar, and softened butter until smooth. Spread this filling evenly over the cooled cookie base.
- Make Chocolate Ganache: Melt the chocolate chips with heavy cream together until smooth and glossy. Pour the ganache over the peanut butter filling, spreading gently to cover.
- Chill and Serve: Chill the assembled cookie in the refrigerator for 20 minutes to set the ganache. Slice into 8–10 wedges and enjoy!
Notes
- Can be made keto: swap sweeteners and use almond flour substitute mix.
- Add flaky sea salt on top for an extra burst of flavor.
- Freezer-friendly: freeze slices up to 2 months, wrapped tightly.
