How To Make This Peanut Butter Brownies Recipe

STEP ONE: Preheat the oven to 350°F. Line an 8×8-inch square baking pan with parchment paper and set it aside.

STEP TWO: Microwave the chocolate chips and oil in a small heat-safe bowl for 45 seconds. Stir and heat ten seconds more. Stir until the chips are melted and the mixture is smooth. Set aside.

STEP THREE: Whisk together flour, sugar, baking soda, and salt in a medium bowl.

STEP FOUR: In another bowl, whisk the eggs, vanilla extract, and milk.

STEP FIVE: Whisk the egg mixture into the dry ingredients, then stir in the melted chocolate chips and mix until just combined. Do not overmix.

STEP SIX: Toss the peanut butter cups in one tablespoon of flour until they are evenly coated. Fold them gently into the batter.

STEP SEVEN: Spread the batter in an even layer in the prepared pan.

STEP EIGHT: With a cookie scoop or tablespoon, drop the peanut butter on top of the chocolate brownie batter and swirl with a knife. Bake for 30 minutes, until the edges are crisp and the middle is set.

STEP NINE: Allow brownies to cool completely before cutting and serving.

How To Serve

These chewy peanut butter brownies are rich enough on their own, but to really send them over the top, serve them warm, topped with a scoop of vanilla ice cream and a drizzle of hot fudge for a super brownie sundae.

Ingredients

  

1x2x3x

• 1½ cups milk chocolate chips
• 3 tablespoons vegetable oil
• ½ cup granulated sugar
• ½ cup all-purpose flour
• ¼ teaspoon baking soda
• ¼ teaspoon salt
• 2 eggs, room temperature
• 2 tablespoons whole milk
• 1 teaspoon vanilla extract
• ½ cup peanut butter cups, chopped
• 1 tablespoon all-purpose flour
• ½ cup creamy peanut butter

Instructions

 

• Preheat the oven to 350°F. Line an 8×8-inch nonstick baking dish with parchment paper and set it aside.
• In a heat-safe small bowl, add the chocolate chips and the oil. Microwave for 45 seconds. Stir the chips and oil, return to the microwave, and heat for another 10 seconds. Stir until the chips and oil are smooth. Set it aside.
• Using a medium-sized mixing bowl whisk together all-purpose flour, granulated sugar, baking soda, and salt. Set it aside.
• In a small bowl, whisk together the eggs, vanilla extract, and milk. Add to the flour mixture. Now add the melted chips and stir until the batter is just combined.
• Toss the chopped peanut butter cups with 1 tablespoon of flour. Fold the coated chopped peanut butter cups into the batter and mix just until all ingredients are combined.
• Pour the batter into the prepared baking dish.
• Using a 1 to 1½ tablespoon cookie scoop or a regular tablespoon, dollop the peanut butter on top of the brownie batter. Use a knife to swirl the peanut butter.
• Bake for 30 minutes.
• Allow the brownies to cool completely before cutting.

Notes

• Refrigerating peanut butter cups for 10 minutes makes them much easier to chop.
• Tossing the peanut butter cups in flour helps them stay suspended in the batter rather than sinking to the bottom of the pan.
• Be careful to not over-swirl the peanut butter so that you’ll get the thick, yummy swirls we’re showing.
• Even though the thought of warm, gooey brownies fresh from the oven sounds amazing, warm brownies are impossible to cut into squares. Speed up the cooling process by putting them in the freezer for half an hour. Once they are cool, use a sharp knife and sawing motion to cut them, wiping the knife clean after each cut. A few seconds in the microwave will bring the brownies back to warm, fudgy perfection.
