Recipe information

  • Yield

    makes about 3 dozen

Ingredients

1 cup (2 sticks) unsalted butter, room temperature, plus more for pan
3 cups all-purpose flour, plus more for pan
1 1/2 cups sugar
2 large eggs
2 1/2 cups smooth peanut butter
1 1/2 teaspoons salt
1 teaspoon baking powder
1 teaspoon pure vanilla extract
1 1/2 cups strawberry jam, or other flavor
1 cup salted peanuts (5 ounces), roughly chopped

Preparation

  1. Step 1

    Preheat oven to 350°F. Butter a 9 by 13-inch baking pan, and line the bottom with parchment paper. Butter the parchment, dust with flour, and tap out excess.

    Step 2

    Place butter and sugar in the bowl of an electric mixer fitted with the paddle attachment. Beat on medium speed until fluffy, about 2 minutes. With mixer running, add eggs and peanut butter; beat until combined, about 2 minutes. Whisk together flour, salt, and baking powder. Add to the butter mixture, and beat on low speed until combined. Add vanilla.

    Step 3

    Transfer two-thirds of mixture to prepared pan; spread evenly with an offset spatula. Using offset spatula, spread jam on top of peanut-butter mixture. Crumble remaining third of peanut butter mixture on top of jam. Sprinkle evenly with peanuts.

    Step 4

    Bake until golden, 45 to 60 minutes, rotating halfway through. Tent loosely with foil if bars are getting too dark. Transfer to a wire rack to cool. Run knife around edges and refrigerate, 1 to 2 hours. Cut into about thirty-six bars (about 1 1/2 by 2 inches). Cookies can be stored in airtight containers at room temperature up to 3 days.
