Ingredients

Directions
-
Preheat your oven to 350°F and line a 9×13‑inch baking pan with parchment paper.

Spread the remaining brownie batter over the Reese’s cups, making sure they’re fully covered.

Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs. Allow to cool completely.
-
To make the peanut butter frosting, beat together creamy peanut butter and softened butter until smooth. Gradually add powdered sugar, then heavy cream and vanilla, beating until light and fluffy.

FAQs
What type of brownie mix should I use?

Use a sharp knife and wipe it clean between cuts for neat slices.
