Pro Tips for the Perfect Peanut Butter Cup Brownies
- Shiny Tops Come From Sugar + Heat: Whisk both sugars into the warm chocolate-butter mixture. This helps dissolve sugar crystals and creates that signature crackly top.
- Egg Emulsion = Fudge Factor: Whisk the eggs thoroughly before folding in the dry ingredients. Consequently, you’ll lock in a dense, fudgy crumb.
- Gentle Folding Prevents Toughness: Add flour and cocoa last, then fold just until streaks disappear. Overmixing builds gluten, which can make brownies cakey.
- Mid-Bake Tap for Even Texture: After 12 minutes, tap the pan twice on the counter. Air bubbles rise and collapse, and the top becomes glossy.
- Candy Placement Matters: Bake most cups inside the batter and press the rest on top as soon as the pan comes out. They’ll melt slightly and set into picture-perfect bites. If you adore peanut butter candy bakes, peek at this fun cousin: Peanut Butter Cup Cake Roll.

Directions:
- Prep the Pan: Preheat the oven to 350°F (177°C). Line an 8×8-inch pan with parchment, leaving overhang on two sides for a sling. Set aside.
- Melt the Base: Over a double boiler, melt butter and chocolate until smooth and glossy. Remove from heat and cool 5 minutes.
- Build the Shiny Batter: Whisk in granulated and brown sugars until combined and slightly thickened, about 1 minute.
- Add Eggs and Vanilla: Whisk in eggs and vanilla until the mixture looks satiny and well emulsified.
- Fold Dry Ingredients: Add flour, cocoa, and salt. Using a spatula, fold gently just until no dry pockets remain. Do not overmix.
- Layer the Candy: Spread about ⅔ of the batter in the pan. Evenly scatter half-pieces of mini peanut butter cups over the surface.
- Cover and Level: Dollop the remaining batter on top. Use an offset spatula or knife to smooth it into an even layer.
- Bake, Tap, and Finish: Bake on the center rack for 12 minutes. Remove and tap the pan twice firmly on the counter. Return to the oven and bake 8–12 minutes more. The edges will look set and pull slightly from the sides; the center should no longer jiggle.
- Top with More Cups: Immediately press the remaining peanut butter cups into the hot surface so they melt in place.
- Cool, Lift, and Slice: Cool completely in the pan on a rack. Use the parchment sling to lift, then slice into neat squares. Serve and enjoy. If you like bright brownie twists, these zesty bars are sunshiney and fun: Amazing Lemon Brownies.
