Amazing Peanut Butter Brownies

These peanut butter brownies skip the cocoa and chocolate-from-the-start approach entirely, building a chewy peanut butter blondie base and adding chocolate chips both inside and on top. The chocolate-on-top gets melted briefly and swirled with a knife, creating a marbled finish that looks impressive and delivers chocolate-and-peanut-butter in every bite.

The brief 3-minute initial bake-and-marble is the trick. Pulling the pan early to swirl molten chocolate chips across the surface gives that signature marbled top without baking it dry. Quickly returning to the oven for the rest of the bake fuses the chocolate into the surface so it stays glossy.

Use crunchy peanut butter as the recipe specifies. The little nut bits add textural contrast that smooth peanut butter brownies lack. If you only have smooth peanut butter, stir in 2 tablespoons chopped roasted peanuts to mimic the texture.

Pro Tips

• Bring butter and eggs to room temperature before mixing for the smoothest batter.
• Don’t overbake; pull when the edges pull from the sides and the center is just set. Overbaked peanut butter bars turn dry and crumbly.
• Cool completely in the pan before cutting; warm bars tear and lose their shape.
• Use a hot, clean knife wiped between cuts for the cleanest brownie squares.

Variations

• Use white chocolate chips for half of the chips for a chocolate-and-white-chocolate marble.
• Add 1 cup chopped roasted peanuts to the batter for extra crunch.
• Drizzle cooled bars with melted peanut butter for double PB richness.
