Peanut Butter Swirl Brownies
Yield: 16 brownies
These peanut butter swirl brownies are rich, decadent, and highly addictive for chocolate peanut butter lovers. The brownies are made with moist, fudgy, and chewy brownies with a thick swirl of creamy peanut butter. Add a sprinkle of flaky sea salt for the perfect bite.
Equipment
Ingredients
- ¾ cup (170 g) unsalted butter
- 1 cup (220 g) light brown sugar
- ½ cup (100 g) granulated sugar
- 2 (2) eggs room temperature
- ¼ cup (59 ml) vegetable oil
- 2 tsp (2 tsp) vanilla extract
- 1 cup (125 g) all-purpose flour
- ⅔ cup (57 g) dark cocoa powder
- ¾ tsp (1 tsp) salt
- ¼ tsp (0.2 tsp) baking powder
- ½ cup (129 g) creamy peanut butter
Instructions
- Preheat the oven to 350℉ and prepare an 8×8 baking pan with nonstick cooking spray and parchment paper.
- In a microwave-safe bowl, combine unsalted butter and brown sugar. Heat in the microwave for 90 seconds until the butter is fully melted. Whisk the butter and brown sugar together until combined and smooth.
- In a large mixing bowl, add eggs and granulated sugar. Use an electric hand mixer to whip the eggs and sugar on medium-high speed for a few minutes until light and pale in color.
- Slowly add the melted butter mixture into the egg mixture while mixing on medium speed with the hand mixer to temper the eggs. Once all the butter mixture is added, add in vanilla extract and vegetable oil and mix until combined.
- In a separate bowl, whisk together the all-purpose flour, dark cocoa powder, salt and baking powder. Add the dry ingredients into the wet ingredients and mix on low speed until well combined and smooth.
- Pour the brownie batter into the prepared baking pan. Use an offset spatula to spread the batter evenly in the pan. Melt the peanut butter in the microwave for 30 seconds. Pour the melted peanut butter over the brownies. Use an offset spatula or butterknife to swirl the peanut butter into the brownie batter.
- Bake the brownies for approximately 25-28 minutes until the center of the brownies is set. To check for doneness, insert a toothpick into the center of the brownies. The toothpick should come out with moist crumbs, not wet brownie batter. If there is wet brownie batter, bake for a few more minutes.
- Remove the pan from the oven and cool the brownies in the pan to room temperature. Remove the brownies from the pan and cut into squares.
