Triple Peanut Blondies are the ultimate in peanut and peanut butter flavor but sometimes even peanut butter lovers want just a little less. These simple, easy to make Peanut Butter Blondies have just the right amount peanut buttery goodness, without needing a long list of ingredients.

You can make Peanut Butter Blondies without a mixer if you don’t have one. Microwave the butter and peanut butter until melted, stirring to combine. The melted butter mixture will stir easier, making sure you don’t over-mix by hand. Plus the melted butter will give your blondies a fudgy center.

Peanut butter gets to be the star of the show in these delicious blondies. No extra peanuts, peanut butter chips, or a ton of sugar in this Peanut Butter Blondies recipe. These brownie-like bars only have brown sugar for extra rich, chewy blondies. The molasses from the brown sugar adds a subtle layer of caramel flavor too.

Tips for Making Peanut Butter Blondies

  • You can use either creamy peanut butter or crunchy peanut butter in Peanut Butter Blondies. Don’t use a natural peanut butter or one that requires stirring because the oils will separate during baking.
  • Try other nut butters like almond butter or sunflower butter if you have them on hand. Just make sure they don’t have a lot oil or separate easily.
  • Cool Peanut Butter Blondies completely before cutting and serving. If you try to cut them warm, they will be too soft and crumbly to eat as a bar.
  • You can add your favorite brownie and blondie mix-ins to these Peanut Butter Blondies. Whether it’s nuts and baking chips or candy pieces, make sure the total added ingredients isn’t more than 1 cup.

For extra sweet, peanut butter flavor, top the cooled blondies with a Peanut Butter Frosting before cutting. If you just can’t wait for your Peanut Butter Blondies to cool, scoop them out and serve in a bowl like a cobbler, topped with Vanilla Ice Cream or Whipped Cream!

  • Chocolate Chips: Fold in baking chips like milk chocolate chips, semi-sweet chocolate chips, peanut butter chips, white chocolate chips, or butterscotch chips. You can use all one type or a mixture up to 1 cup total.
  • Chocolate Swirl: Stir melted chocolate or Chocolate Ganache through the blondie batter for a marbled Chocolate Peanut Butter Blondie. You can also drizzle baked blondies with melted chocolate or Salted Caramel Sauce.
  • Peanut Butter Cups: Place 10 miniature Reeses peanut butter cups into where the center of each blondie would be before baking. The peanut butter cups will sink into each bar for a melty, chocolate peanut butter center.
  • Cake Mix: You can use a box of yellow cake mix or vanilla cake mix instead of the dry ingredients, white sugar, and brown sugar.
  • Candy: Mix in candy pieces like toffee bits, Reese’s Pieces, M&Ms, or chopped soft Salted Caramels for an extra sweet bite.
  • Nuts: You can always double the peanut flavor with salted peanuts. Add other chopped nuts like pecans, walnuts, or macadamia nuts, too.



  • Serve: Cool Peanut Butter Blondies at least 15 minutes before serving. They can be kept covered at room temperature for up to 4 days.
  • Store: Transfer Peanut Butter Blondie squares to an airtight container and refrigerate for up to 1 week. Bring to room temperature or warm in the microwave for best taste and chewy bites.
  • Freeze: Cut Peanut Butter Blondies and place on a baking sheet. Freeze for 1 hour, then transfer to a sealed container and freeze for up to 3 months. Thaw blondies overnight in the refrigerator before serving.
