Ingredients
- 1 cup unsalted butter, room temperature
- 2 cups sugar
- 2 tsp vanilla
- 4 eggs
- 4 oz unsweetened baking chocolate, melted
- 1 cup flour, sifted
- 1 cup peanut butter chips
- 1/2 cup creamy peanut butter
Preparation
Step 1
Preheat your oven to 325 F degrees. Grease a 9×15 cake pan.
Cream together the butter, sugar, and vanilla.
Add the eggs and beat until light and fluffy, about 3 minutes. Make sure to scrape the sides/bottom of the bowl!
With the mixer on low, slowly pour in the melted chocolate. Scrape the sides and mix on medium/high speed about 30 seconds.
By hand, mix in the flour until just incorporated.
Fold in the peanut butter chips
Spread batter evenly into the pan.
Dollop the peanut butter on top of the batter. Using a knife, gently swirl the peanut butter into the batter. Not too much though, you don’t want the entire top to be covered in peanut butter, just a nice swirl.
Bake for 30-35 minutes or until a toothpick comes out clean.
Let cool for at least 10 minutes before cutting and serving!
