Ingredients
Main Ingredients
- 1 cup unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs
- 1 tablespoon vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 0.5 teaspoon salt
- 0.75 cup creamy peanut butter
- 0.5 cup grape or strawberry jelly
Instructions
Preparation Steps
- Preheat oven to 350°F (175°C). Grease a 9x13-inch baking pan or line with parchment paper.
- In a large bowl, whisk together melted butter and sugar until smooth. Add eggs one at a time, mixing well after each addition. Stir in vanilla.
- In a separate bowl, whisk together flour, baking powder, and salt. Gradually add dry ingredients to wet ingredients, mixing until just combined.
- Pour half of the batter into the prepared pan and spread evenly. Drop spoonfuls of peanut butter over the batter and gently swirl with a knife.
- Pour remaining batter over the peanut butter layer. Drop spoonfuls of jelly on top and swirl through the batter to create a marbled effect.
- Bake for 28–32 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
- Cool completely in the pan before cutting into 16 squares.
