Directions
1. Prepare the Blondie Base
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it.
In a medium bowl, whisk together the melted butter, brown sugar, and peanut butter until smooth. Add in the eggs and vanilla extract and stir until well combined.
In a separate bowl, mix the flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, stirring until a thick batter forms.
2. Bake the Blondies
Pour the batter into the prepared baking pan and spread it evenly. Bake for 22–25 minutes, or until the edges are golden and a toothpick inserted in the center comes out clean.
Let cool completely in the pan before frosting.

3. Make the Frosting
In a saucepan over low heat, melt the butter and peanut butter together, stirring until smooth. Remove from heat and whisk in the milk and vanilla.
Gradually add the powdered sugar, beating until smooth and thick. If the frosting is too thick to spread, add 1 teaspoon of milk at a time until desired consistency is reached.
4. Frost and Cut
Spread the warm frosting over the cooled blondies. Let it set for about 20 minutes before cutting into squares.
