Reese's Peanut Butter Blondies are a chewy and delicious treat, filled with creamy peanut butter, Reese's Peanut Butter Cups, and chocolate chips. This easy recipe creates the perfect balance of sweet peanut butter flavor and chocolate in every bite.
Preheat your oven to 350°F. Lightly spray an 8-inch square (or equivalent size) baking dish with non-stick spray.
Whisk together the melted butter and brown sugar until smooth and well combined. Add the peanut butter, egg, and vanilla extract, mixing until fully incorporated.
Sift in the flour, baking powder, and salt together. Add to the wet ingredients and stir gently until just combined.
Gently fold in the chopped Reese’s Peanut Butter Cups and chocolate chips, ensuring they’re evenly distributed throughout the batter.
Pour the batter into the prepared baking pan, spreading it evenly. Bake for 25-30minutes, or until a toothpick inserted into the center comes out mostly clean (a few moist crumbs are fine for a chewy texture).
Let the blondies cool completely before slicing them.
