PEANUT BUTTER AND JELLY BLONDIES

A PB&J sandwich is an old school kid favorite that takes you back to simpler summer days of running through sprinklers, playing tag, and Saturday morning cartoons. Every so often, gourmet chefs try to reinvent these iconic sammies with fancy or exotic ingredients. But as good as the critics say those new PB&J recipes are nothing beats the classic flavors of peanut butter and jelly.

Peanut Butter and Jelly Blondies are moist and chewy blonde brownies filled with peanut butter and fruit flavor. The slightly salty creamy peanut butter gets perfectly balanced with the sweet strawberry preserves, just like a PB&J sandwich! Seriously, you’ll be amazed how much these taste exactly the lunchbox classic.

For these Peanut Butter and Jelly Blondies you can use creamy or crunchy peanut butter. If you are firmly in the “chunky peanut butter is best” camp, you’ll love the texture and crunch it adds. But you should not use natural peanut butter, creamy or not. Natural peanut butter is too oily for baking and changes the texture of baked goods. 

Since this recipe is inspired by a classic PB&J sandwich, Peanut Butter and Jelly Blondies uses strawberry jam. You can use any of your favorite jelly or jam flavors. Jelly is a little thinner and is easier to swirl, but jam has bigger chunks of fruit. It really comes down to your preference!

Keep your Peanut Butter and Jelly Blondies on the counter for a quick after school snack, they will last about 4 days in a sealed bag. For a cool summer dessert, serve these PB&J Blondies with Vanilla Ice Cream. Turn them into a rich, peanut buttery strawberry shortcake by topping with Whipped Cream and Strawberry Topping!

What’s the difference between Blondies and Brownies?

Blondies are basically vanilla and brown sugar brownies. the biggest difference besides not using cocoa powder is adding brown sugar which makes a rich, vanilla caramel batter. The mild vanilla brownie batter allows added ingredients like peanut butter and jelly to really shine. For even richer brownies, use all brown sugar instead of white sugar.

VARIATIONS ON PEANUT BUTTER AND JELLY BLONDIES

  • Jelly and Jam: Use your favorite jam or jelly flavors like grape jelly, raspberry jam, or orange marmalade instead of the strawberry jam.
  • Peanut Butter: Instead of peanut butter, use another nut butter like cashew butter or almond butter. You can use cookie butter or chocolate hazelnut spread, too!
  • Peanuts: Sprinkle chopped honey roasted peanuts or salted peanuts over your PB & J Blondies before baking for an extra crunch!
  • Baking Chips: Stir in 1/2 cup of your favorite baking chips to the peanut butter batter. Try chocolate chips, white chocolate chips, peanut butter chips, or toffee bits.
  • Fresh Strawberries: Add chopped fresh strawberries for even more fruity flavor! Gently fold in a 1/2 cup finely chopped (about 1/4 inch pieces) to the batter before pouring in the pan.
  • PB and Jelly Blondie Bites: Prepare Peanut Butter Blondie batter as usual and pour into a 24 cup greased mini muffin pan. Use a spoon to make an indent in each cup and fill with a teaspoon of strawberry jam. Bake at 350 degrees F for 14 to 16 minutes.
