Ingredients
Peanut Butter Blondies
- 1/2 cup creamy peanut butter
- 1/2 cup salted butter melted
- 3/4 cup light brown sugar
- 1 large egg
- 1 large egg yolk
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/4 teaspoon salt
Peanut Butter Frosting
- 1 cup creamy peanut butter
- 1/2 cup salted butter softened
- 1/2 teaspoon vanilla extract
- 2 Tablespoons heavy cream
- 1 cup powdered sugar
- 1/2 cup Reese's Pieces
Instructions
- Heat oven to 350°F. Line a square 8x8 baking dish with a parchment paper sling.
- In a large bowl, whisk the peanut butter and butter together until smooth and creamy. Add the brown sugar, egg and extra egg yolk, and vanilla and mix well to combine.
- Stir in the flour and salt with a spoon, then spread into the prepared baking dish, pushing towards the edges of the pan as needed. Sprinkle with Reese's Pieces, if not planning to frost.
- Bake for 20-25 minutes until done, then remove from oven and cool completely. Do not overbake.
- Prepare the frosting by beating the peanut butter and butter together until smooth and creamy. Add the vanilla, cream and powdered sugar and beat well, then frost the peanut butter blondies in the pan and sprinkle with Reese's Pieces. Cut into squares and serve.
Notes
- Mix-ins: Add 3/4 to 1 cup chocolate chips, peanut butter chips, or white chocolate chips to the batter, if desired.
- Disneyland peanut butter blondies: You might have seen a version of these at Disney that skips the frosting and instead just spreads a layer of peanut butter on the blondies while they are still warm from the oven. Then the top is generously sprinkled with even more Reese's Pieces than what you see here until it is practically covered.
- Storage: We recommend storing these peanut butter bars in an airtight container at room temperature for 3-4 days or in the fridge for up to 1 week. Let them come to room temperature before serving if refrigerated.
- Freezing: They freeze great for up to 1 month. Just slice into squares and freeze in a single layer on parchment paper for 1 hour before transferring to an airtight container for longer freezing.
- Pan size: A 9x9-inch pan can be used but the bars will be slightly thinner and bake a couple minutes faster. Or you can double the recipe and use a 9x13-inch pan.
