Peanut Butter and Jelly Blondies

These peanut butter and jelly blondies take your favorite childhood sandwich and turn it into a sweet chewy treat. 

 

These peanut butter and jelly blondies include peanut butter in the batter as well as peanut butter and grape jelly swirled on top. 

These blondies are buttery, sweet, and peanutty! 

What are blondies? They are referred to as brownies without the chocolate, but they are much more than that. They are flavored with brown sugar (for a deep molasses flavor) and vanilla and can include add ins, or not. 

I've not made a lot of blondies (except the Toll House Bars, you know the one where you swirl in the chocolate chips after they get all melty.... mmmm!), but these, with the addition of peanut butter and jelly, called my name. 

These blondies are pretty easy to make, there is no mixer required, and you only need one bowl. If you use a kitchen scale and follow the weight ingredient instructions, you will even have a minimal number of dishes to wash! 

Okay, I confess, you will need a couple of bowls for melting the jelly and peanut butter, but other than that, this recipe is a total time saver. 

How to Make Peanut Butter and Jelly Blondies:

First, whisk together both light and dark brown sugar, melted butter, slightly melted peanut butter, baking powder, and salt. 

Next, add the eggs, one at a time, and then fold in the sifted flour and cornstarch. 

After that, spread the batter into a parchment lined 9 inch by 13 inch cake pan and drop tablespoons of slightly warmed jelly and peanut butter over the top of the batter. Draw a butter knife through the peanut butter and jelly to create a swirly pattern. 

Finally, bake the blondies for about 25 to 30 minutes at 350 degrees F. 

Ingredient substitution suggestions:

I used grape jelly for the traditional flavor, but you can use any flavor jelly you like. If you choose to use a jam or preserves, be sure to puree it in a food processor so that you can evenly swirl it with the peanut butter. 

For the peanut butter in the batter, I used smooth peanut butter, but feel free to use chunky. I do not recomment "natural" peanut butter.
