PB and J Bars

1. 
   
   

   • 1 cup (2 sticks) unsalted butter, room temperature, plus more for pan
   • 3 cups all-purpose flour (I used 2 of AP and 1 of WW)
   • 1 1/2 cups sugar
   • 2 large eggs
   • 2 1/2 cups  peanut butter (I used crunchy)
   • 1 1/2 teaspoons salt
   • 1 teaspoon baking powder
   • 1 teaspoon vanilla extract
   • 1 1/2 cups  jam - any flavor will do
   • 2/3 cup salted peanuts, roughly chopped
   
   

   1. Heat oven to 350 degrees. Grease a 9-by-13-inch pan  Mix butter and sugar in bowl.  Beat on medium-high speed until fluffy, about 2 minutes. On medium speed, add eggs, vanilla and peanut butter; beat until combined, about 2 minutes.
   2. Whisk together salt, baking powder, and flour. Add to bowl of mixer on low speed; combine. Transfer two-thirds of mixture to prepared pan; spread evenly. Spread jam on top of peanut-butter mixture. Dollop remaining third of peanut-butter mixture on top of jam. Sprinkle with peanuts.
   3. Bake until golden, about 30-40 minutes. Transfer to a wire rack to cool; then cover and refrigerate for an hour before cutting into about thirty-six 1 1/2-by-2-inch pieces.
