Peanut Butter and Jelly Bars
There is something so comforting about peanut butter and jelly. The classic peanut butter and jelly sandwich is a combination of three foods that have been around for a long time: sliced bread, peanut butter, and jelly. These peanut butter and jelly bars give you the same flavors as the classic sandwich in a bar form.
PB & J Bars Ingredients
Peanut Butter: I used both creamy and crunchy peanut butter in this recipe. You could definitely stick to using all of one or the other per your preference.
Preserves: Strawberry preserves are spread in between the layers of peanut butter bar batter. You could use jelly or jam. And, of course, use your favorite flavor!
Peanuts: Chopped peanuts top the bars for a little extra crunch in every bite. You could leave those off if there is enough nuttiness in the bars for you already.
How to Make Peanut Butter Bar Dough
These bars are pretty simple to make and can be enjoyed any time of the day, from morning (breakfast, anyone?) to a dessert! To get started, line a 9×13-inch pan with parchment paper and get out a large bowl and handheld mixer.
First, cream together both kinds of peanut butter, butter, and both kinds of sugar. Mix the ingredients until they are well-blended. Then, mix in the egg and vanilla until incorporated.
In a separate bowl, whisk together the flour, baking powder, and kosher salt before mixing in with the creamed mixture. This is the bar dough that will be the bottom layer and dolloped on top of the layer of jam.
How to Make Peanut Butter and Jelly Bars
Once the dough is mixed and ready to go, it’s time to get the peanut butter and jelly bars layered and baked. First, spread about 2/3 of the dough onto the bottom of a lined 9×13-inch baking dish. Next, evenly spread out the strawberry preserves over the dough.
Then, dollop the remaining dough over the preserves. Top with chopped peanuts (if using) and cover the pan. Bake the bars for about 30 minutes, or until the edges are golden brown. Remove from the oven and let the bars cool completely before serving with a tall glass of milk! (If you can’t wait for them to cool, be ready for an ooey-gooey bar that is still delicious, but messy!)
Store the bars in an airtight container at room temperature for up to 3 days. They will last a couple of days longer when stored in the refrigerator.
