If you're a peanut butter lover, these Peanut Butter Blondies deserve a spot on your baking list. They're soft, chewy, and loaded with peanut butter flavor in every bite. Chopped peanuts add a satisfying crunch, while a dusting of powdered sugar gives them a simple finishing touch. They're easy to make with pantry staples and are just the thing for bake sales, holiday cookie trays, afternoon coffee breaks, or whenever you're craving an easy homemade treat.
What makes this recipe irresistible
These Peanut Butter Blondies are packed with rich peanut butter flavor in every bite. They bake up with a soft, chewy center and lightly golden edges that make them irresistible. Chopped peanuts add just the right amount of crunch, creating a delicious contrast in texture while giving every square an extra boost of nutty goodness.
I especially like that these blondies aren't overloaded with chocolate or frosting. They let the peanut butter shine, giving them the nostalgic, old-fashioned flavor I remember from Grandma's kitchen.
Peanut Butter Blondie Recipe
Ingredients
- ½ cup chunky peanut butter
- ¼ cup butter softened
- 1 teaspoon vanilla extract
- 1 cup brown sugar firmly packed
- 2 large eggs
- ½ cup all purpose flour
- 1 cup chopped peanuts
- ¼ cup powdered sugar
Instructions

- Add the flour in two batches, mixing just until combined. Fold in the chopped peanuts.

Frequently asked questions (FAQ's)
Yes! Creamy peanut butter works just as well. If you use creamy peanut butter, you'll still get plenty of texture from the chopped peanuts folded into the batter.
The edges should be lightly golden and the center should look set. A toothpick inserted near the center should come out with a few moist crumbs. Be careful not to overbake, or the blondies may lose their chewy texture.
Yes! Fold in ½ to 1 cup of chocolate chips, peanut butter chips, or butterscotch chips for an extra layer of flavor. Mini chocolate chips work especially well because they distribute evenly throughout the bars.
Deb's test kitchen notes
This recipe comes from my grandma's recipe box, and honestly, I didn't want to change much because it has stood the test of time. During testing, the biggest thing I learned was not to overbake the blondies. Pull them from the oven when the center is just set and a toothpick comes out with a few moist crumbs.
They'll continue to firm up as they cool, giving you that soft, chewy texture that makes these bars so irresistible. Let them cool completely before dusting with powdered sugar and slicing for the cleanest cuts.
