Instructions
1
Preheat the oven to 320℉.
2
Line the 8"x8" pan with parchment paper or grease with cooking spray or butter. Set aside.
3
Combine the brownie mix with water, egg, and oil. Use an electric mixer or whisk and blend until smooth.
4
Pour the mixture evenly into the square pan.
5
Spoon small dollops of peanut butter over the top. Use a knife, skewer, or toothpick to gently swirl it into the batter, creating a marbled effect. Be careful not to overmix—you want distinct swirls, not fully blended batter.
6
Bake at 320℉ for 15-18 minutes or until a toothpick inserted in the center comes out clean.
7
Cool completely on a wire cooling rack before cutting into squares.

Tips & Tricks (5)
- Peanut Butter Swirl Perfection 🌀Warm your peanut butter slightly before swirling to ensure it blends smoothly into the batter without clumping, creating beautiful ribbons throughout.
- Oil Substitution Strategy 🫗Replace vegetable oil with melted coconut oil or browned butter for deeper, more complex flavor that elevates the premium quality of your brownies.
- Underbaking for Gooeyness 🍫Remove brownies 2-3 minutes before the toothpick comes completely clean—they'll continue cooking as they cool, resulting in that irresistibly fudgy center.
- Room Temperature Ingredients Matter 🌡️Bring eggs and peanut butter to room temperature before mixing to ensure even incorporation and a smoother, more consistent batter texture.
- Double-Layer Technique 🎯Pour half the brownie batter first, add peanut butter swirls, then top with remaining batter for distinct layers and maximum peanut butter distribution in every bite.
