Thick and chewy peanut butter pretzel blondies! This easy-to-make dessert recipe comes together in minutes with no hand mixer required. It's full of flavor from the peanut butter and the pretzels give it the best crunchy texture.
Preheat oven to 350°F. Line a 9" x 13" pan with parchment paper with overhang on the sides for easy removal.
Melt the butter in a medium saucepan over medium-heat or in the microwave in 30 second increments. Once melted and still warm, stir in the peanut butter and brown sugar, whisk until well-combined.
Whisk in eggs, one at a time, mixing well after each addition. Stir in the salt, flour, and baking powder, mixing just until combined, being careful not to over mix. Fold in the and peanut butter chips and crushed pretzels. Dough will be thick.
Spread the batter evenly into prepared pan, smoothing it lightly with a spatula.
Place one whole pretzel every inch away so one pretzel will top each bar. Sprinkle the top with additional peanut butter chips, if desired.
Bake the blondies for 15 minutes then cover the pan with foil and bake for another 15-18 minutes, or until they're light brown on the edges and top. Carefully remove them from the oven and cool completely before cutting.
Drizzle bars with melted chocolate before or after cutting into squares, if desired.
