Peanut Butter Streusel Brownies

It’s been a while since I baked anything using chocolate and peanut butter. While I do believe variety is a good thing, I also believe with absolute certainty that the combination of chocolate and peanut butter is a very, very good thing.

I’ve made peanut butter brownies many times, but these are different from any of those. The difference? Streusel. Not just any streusel. Peanut butter streusel. I’m pretty sure that’s a new one for me.

Dark, rich brownies and a crunchy peanut butter topping combine for these Peanut Butter Streusel Brownies. A must for fans of chocolate and peanut butter! - Bake or Break

That sweet, nutty peanut butter streusel tops off a dark, cakey brownie for quite the chocolate-peanut butter experience.

I do recommend using crunchy peanut butter for the streusel to give it a little crunch. If you don’t have that, you can always mix in a tablespoon or so of chopped roasted peanuts.

I’ll pretty much take chocolate and peanut butter in most any combination. But, one of my favorite things about these bars is that you get a layer of each. That way each flavor gets its own little moment to shine while you devour your brownie.

Peanut Butter Streusel Brownies

Prep Time: 25 minutes

Cook Time: 54 minutes

Yield: 16 2-inch bars

Peanut Butter Streusel Brownies


    For the brownies:
  • 4 ounces unsweetened chocolate
  • 3/4 cup unsalted butter
  • 1 & 1/2 cups granulated sugar
  • 1/2 cup packed light brown sugar
  • 3 large eggs
  • 1 cup all-purpose flour
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • For the streusel:
  • 1/2 cup all-purpose flour
  • 1/3 cup crunchy peanut butter
  • 2 tablespoons granulated sugar
  • 2 tablespoons light brown sugar
  • 2 tablespoons unsalted butter, melted
  • 1/8 teaspoon salt


Line an 8-inch square baking pan with aluminum foil or parchment paper, leaving a couple of inches of overhang on 2 opposite sides. Grease lining.

Place chocolate and butter in a large microwave-safe bowl. Heat in microwave at half power in 30-second increments until butter melts and chocolate melts when stirred. Stir until smooth. Allow to cool slightly.

Preheat oven to 350°.

Add sugar and brown sugar to chocolate mixture and stir until blended. Add eggs, one at a time, mixing just until blended after each addition. Stir in flour, vanilla, and salt.

Transfer batter to prepared pan.

To make the streusel, mix flour, peanut butter, sugar, brown sugar, butter, and salt. Stir (or use a fork) until blended and crumbly. Sprinkle streusel mixture evenly over brownie batter.

Bake 50-54 minutes, or until a pick inserted into the center comes out with a few moist crumbs. Cool completely in pan on wire rack. Then, use the overhanging lining to remove brownies from pan. Cut into bars.

  1. This is very inventive! I’ve never seen a streusel topped brownie before. I love peanut butter and chocolate, so this is a must. When the red velvet cream cheese brownies I baked are gone, these will be next!

    Very creative, indeed! I never would’ve thought to combine a streusel topping with either pb or chocolate. And this combination is so amazingly delicious…I just had the good fortune of trying one over here at SP! Thanks for sharing!!

    Diane, you can double the recipe. Just be sure to check the center for doneness. You may need to bake them a little longer.

    Mary, substituting cocoa powder can be a bit tricky. If you have a brownie recipe you like that uses cocoa powder, you can use that as a base for the streusel.

    Just made these for my two Valentines…they did not disappoint! My son couldn’t even wait for them to cool. The brownies alone would be wonderful as well but the streusel is on another level!
