Instructions
Brownie Base
Preheat the oven to 325°F (163°C). Line an 8×8 or 9×9-inch pan with parchment paper.
Melt the butter and chopped chocolate together over low heat or in short microwave bursts. Stir until smooth.
Add granulated and brown sugar and stir until glossy. Then whisk in the eggs and vanilla until thickened.
Sift in flour, cocoa powder, salt, and stir just until combined, don’t overmix.
Spread batter into the prepared pan and smooth the top.
Bake for 45–55 minutes or until a toothpick inserted into the center comes out with moist crumbs. Let cool completely in the pan before adding layers.
🤎Shortcut alert!🤎
You can use your favorite brownie box mix instead of making the entire thing from scratch 🫠. Just make sure to add 2 eggs for extra moist brownie batter; and then all you have to do is work on the super simple peanut butter layer and the ganache! 🤎
Peanut Butter Layer
In a mixing bowl, beat peanut butter and softened butter together until smooth and fluffy.
Mix in vanilla and salt (if using), then gradually beat in the powdered sugar until thick and spreadable.
Spread evenly over the cooled brownie base using an offset spatula. Chill in the refrigerator for 15–30 minutes.
Chocolate Ganache
Heat cream in a small saucepan or in the microwave until just simmering (not boiling). Pour over the chocolate in a heatproof bowl and let sit for 1–2 minutes.
Stir gently until smooth and glossy. Add butter and a pinch of salt if using.
Let the ganache cool for 5–10 minutes, then pour over the chilled peanut butter layer and spread evenly. Chill for at least 1 hour until set.
Slice and serve!
