All about Peanut Butter and Jelly Bars

These Peanut Butter and Jelly Bars are the perfect combination of peanut butter cookies, oatmeal cookies, and PB&J.  They make a great snack or after school treat but are also a great dessert.  Most people have peanut butter in the cupboard and a jar of jelly in the refrigerator.  Which makes it a great cookie bar to make because you have all the ingredients on hand. 

The other great thing about these cookie bars is that they are so easy to make.  When you feel like baking a treat but you don’t want to make actual cookies, this is the lazy and easy way to make this happen.  You make the batter and press 2/3 of the it at the bottom of the pan and then drop spoonful’s of jelly, and the spoonful’s of the remaining batter before popping it into the oven.  It is easy peasy lemon squeezy! In about 45 minutes you have a delicious cookie treat.

  • 1/2 cup unsalted butter slightly softened
  • 3/4 cup brown sugar lightly packed
  • 3/4 cup creamy peanut butter
  • 1 large egg
  • 1 1/2 tsp vanilla extract
  • 1/2 cup all-purpose flour
  • 1/4 tsp salt
  • 1/4 tsp baking powder
  • 1 cup old-fashioned rolled oats
  • 1/2 cup strawberry jam or jelly of your choice


  1. Preheat oven to 350 degrees F; line an 8×8 inch baking pan with 2 pieces of parchment paper so it hangs over all 4 sides.

  2. Cream together the butter and sugar. Beat in the peanut butter, egg and vanilla. Then add the flour, salt, and baking powder. Beat just until combined and be careful not to overmix. Stir in the oats.

  3. Press 2/3 of the batter into the bottom of the prepared pan. Spread the jam or jelly on top, leaving a rim of about 1/4 an inch all the way around. Crumble the remaining 1/3 of the dough on the top.

  4. Bake until the bars look golden along the outside, about 32 minutes for gooey bars in the center, or up to 38 minutes for more set bars, being careful not to overbake.

  5. Cool completely before cutting and serving. Store any leftovers wrapped at room temperature for up to 3 days.

Recipe Notes

Feel free to switch up the flavor of the jam or jelly with whichever is your favorite!

How long will they keep?

Let’s be honest, these and most cookies and cookie bars taste the best the same day they are made.  With that said, these cookie bars will last a couple of days in an airtight container at room temperature.  After that, they will remain fresh if placed in the refrigerator if they even last that long in your house.  They always get eaten very quickly in our home!
