Description
Soft peanut butter and jelly blondies with chewy centers and swirled topping. This easy PB and J blondies recipe uses one bowl and bakes quickly.
Ingredients
- 1/2 cup unsalted butter
- 1/4 cup creamy peanut butter
- 1 cup light brown sugar packed
- 1 large egg
- 1 teaspoon vanilla powder
- 1/2 teaspoon baking powder
- 1/4 teaspoon fine sea salt
- 1 1/4 cups all-purpose flour
- 1/3 cup creamy peanut butter (for topping)
- 1/3 cup strawberry or grape jam (for topping)
Instructions
- Heat oven to 350°F. Line an 8-inch square baking pan with foil, leaving overhang on two sides, then lightly grease the foil.
- Heat butter and peanut butter in a microwave-safe bowl until melted, about 45 to 60 seconds. Stir until smooth and cool for 2 minutes.
- Stir brown sugar into the butter mixture until glossy. Mix in the egg and vanilla powder until well combined.
- Add baking powder and salt. Sprinkle flour over the batter and stir just until no dry flour remains.
- Spread the batter evenly into the prepared pan.
- Warm the topping peanut butter and jam separately for 10 seconds until just loosened, but not runny.
- Drop small spoonfuls of the topping peanut butter and jam over the batter surface.
- Gently swirl only the top layer with the tip of a knife to create a marbled pattern.
- Bake for 30 to 35 minutes. The center must be set and stop jiggling when you gently shake the pan.
- Cool completely before lifting the blondies from the pan and slicing.
Notes
- Light swirling keeps the peanut butter and jam visible on the surface.
