 Back to School

Back to school is around the corner and there’s nothing that makes me think of “school” more than peanut butter and jelly sandwich. I used to have it for lunch nearly every day, and it’s still something I love to whip up today. It’s also one of my favorite flavor combinations to use in desserts – peanut butter and jelly cake, peanut butter and jelly thumbprint cookies, peanut butter and jelly muffins, peanut butter and jelly cupcakes, and these easy peanut butter and jelly bars.

These easy-to-make PB&J bars are so simple to make and taste just like a peanut butter and jelly sandwich. If you’re like me and love this simple sandwich, you’ll go nuts for these yummy bars! The shortbread crust and crumble is much like the white bread, stuffed with a jam flavor of your choice (I used raspberry jam) and peanut butter chips.

I highly recommend that you use the Hershey’s Peanut Butter Chips when you’re making these bars. They are the best of the best and taste better than any other peanut butter chip I’ve tried.

Ingredients You’ll Need for Easy Peanut Butter and Jelly Bars

How to Make Peanut Butter and Jelly Bars

After the bars have baked, allow them to cool for about 15 minutes before serving. They’re delicious served warm and also at room temperature.

    Just wanted to let you know that the recipe skips the step of adding the flour mixture to the butter 😊

    1. Fixing it right now! thank you!

  2. Hey! I used GF flour which usually comes out ok and the crumb was beautiful but as soon as I put the eggs in it turned to more of a cake? Maybe the eggs were too large? What would you have done to fix that??

    1. The eggs shouldn’t be a problem. It might be the GF flour. I’m not sure with that one! I’m sorry!

  3. Just made these bars today with my little girl, we had so much fun! They are delicious and we’ll be doing a surprise delivery of some to our friend for her birthday (she loves pb&j).
    Also I want to thank you for your awesome tutorial videos on instagram🤗
