These peanut butter and jelly bars are similar my fudge-filled peanut butter cookie bars from my eCookbook. There’s a chewy peanut butter crust layer, jelly layer, and crunchy topping. This recipe is for those of you who prefer fruity desserts over chocolate.

The filling is nothing more than jelly or jam from a jar. Choose any flavor you want. It doesn’t have to be grape. Maybe you’re a strawberry lover. Or apricot lover. If you make your own jellies and jams, you can use that too!

You need just a few ingredients to make these bars and I’m fairly certain you already have them on hand. Or most of them at least.

The base and topping are made with butter, peanut butter brown sugar, eggs, vanilla, flour, salt, and baking powder. I used crunchy peanut butter because I like the texture but if you prefer creamy then use that instead.

There are no special trick or long periods of wait time with these bars. Mix the ingredients, layer them in an 8×8 pan, and bake. Too simple.

Use room temperature ingredients

Make sure your ingredients are at room temperature so everything mixes together easily. This rule applies to all baking unless the directions specifically call for cold ingredients.

Beat the peanut butter, butter, and brown sugar together until it smooth and creamy. In goes one egg and vanilla extract. Combine the flour, salt, and baking powder then gently mix it into the peanut butter mixture.

Pro tip: Don’t overmix the batter because the bars will become tough. Mix just until all the dry ingredients are incorporated.

Then press two-thirds of the batter into the bottom of an 8×8 inch pan that’s lined with aluminum foil. Use your hands to press the dough in. Your hands are your best tools.

Layer the jelly over the base and crumble the remaining dough over the top. Sprinkle chopped peanuts over the bars and they are ready to bake. They should only take about 30 to 35 minutes in the oven.

Cool them completely before lifting them out of the pan and slice into squares. The bars will keep for up to 3 days stored in an airtight container at room temperature.
