Peanut Butter Layer
8tablespoonssalted sweet cream butter,room temperature
2cupscreamy peanut butter
2teaspoonspure vanilla extract
12ouncessemi-sweet chocolate chips
Preheat the oven to 350°F. Line a 9x13-inch baking dish with parchment paper. Lightly spray the lined baking dish with baking spray (Baker’s Joy or a generic version). Set it aside.
Add the brownie mix, oil, eggs, and water to a medium-sized mixing bowl. Stir just until combined.
Evenly spread the brownie batter in the prepared baking dish. Bake for 20 minutes. Allow the brownies to cool completely.
Peanut Butter Layer
Using either a stand mixer or a large mixing bowl and a handheld mixer on medium-high speed, beat the butter for 1 minute, or until smooth.
Add the peanut butter and vanilla, and continue mixing on medium-high until the mixture is completely combined and smooth.
Lower the mixer speed to medium-low. Add the powdered sugar 1 cup at a time, mixing well after each cup until well incorporated and smooth.
Once the brownie layer is completely cooled, evenly spread the peanut butter mixture over the brownie layer.
Add the chocolate chips and the heavy cream to a microwave-safe bowl. Heat in the microwave for 45 seconds. Stir and continue heating in 15-second intervals until the ganache is completely smooth.
Using either a silicone spatula or an offset spatula, evenly spread the ganache over the peanut butter layer.
Cover the brownies and chill in the refrigerator for 15 to 20 minutes. Remove the brownies from the refrigerator. Slice 15 slices (2½ inches x 3 inches), and return the covered brownies to the refrigerator to chill for an additional 1 hour 45 minutes.
Remove the brownies from the baking dish by the parchment paper. You may need to carefully re-slice the brownies before serving.
When spreading and smoothing the peanut butter mixture over the cooled brownies, you can place a piece of wax paper to help smooth the mixture.
You can let the brownies chill for the full 2 hours before slicing, but the chocolate layer may crack and not be as pretty as pre-slicing after chilling for 15 to 20 minutes.
