½cup(113 g or 1 stick) unsalted butter, room temperature
1cup(226 g or 8 ounces) creamy peanut butter, (no-stir variety)
¾cup(150 g) granulated sugar
½teaspoonpure vanilla extract
1large egg, room temperature
1 ½cups(187 g) all-purpose flour
½teaspoonbaking powder
½teaspoonskosher salt
¾cupraspberry jelly or other flavored jam
⅓cupsalted peanuts, coarsely chopped
Instructions
Preheat oven to 350 F. Line a 8×8 metal baking pan with parchment paper and set aside.
In the bowl of a stand mixer (or using a hand mixer), beat butter, peanut butter and sugar on medium-high speed until light and fluffy. Add egg and vanilla, then mix until combined. Scrape down the sides and bottom of the bowl as needed.
In a separate bowl, whisk together the flour, baking powder and salt. Add to the wet ingredients and mix until combined.
Transfer two-thirds the mixture to the prepared pan. Use your hands or the back of a measuring cup to press mixture evenly into the bottom to form the crust. Bake the crust for 15 minutes or until golden (keep the oven on).
Spread jelly over baked crust using an offset spatula. Add small spoonfuls of remaining dough over the jam layer. (It’s okay if all the jelly isn’t covered. The dough topping will spread when baked.) Sprinkle with chopped peanuts.
Bake bars for 30 to 35 minutes or until the top is golden brown. Allow bars to cool completely before removing from pan and cutting into 16 squares.
Notes
Jelly can be substituted with jam. Any fruit flavor works well.Store in an airtight container at room temperature for 3 days or in the refrigerator for 1 week.
