- 1½ c. all-purpose flour
- ½ tsp. salt and
- ½ tsp. baking soda
- ½ c. coconut oil or butter
- ¾ c. dark brown sugar
- 1 large egg
- 1¼ c. natural peanut butter
- 1 tsp. vanilla extract
- 1½ c. jam
- ½ c. roasted peanuts
- Adjust oven rack to lower-middle position and heat oven to 350 degrees. Line a greased 13- by 9-inch baking pan with a 13- by 18-inch sheet of parchment to facilitate removal of baked bars. Grease and flour parchment and set aside.
- Mix flour, salt, and baking soda in a medium bowl and set aside. Beat coconut oil and sugar until smooth; beat in egg, then peanut butter, and finally the vanilla extract until smooth. Reduce mixer speed to low, add flour mixture, and beat until fully incorporated.
- Press ⅔ of the peanut butter dough into the prepared pan; spread jam over the dough to cover. Mix peanuts into remaining peanut butter dough, crumbling it over the jam to form a topping
- Bake until jam is bubbly and crust is golden brown, about 45 minutes. Remove from oven and let stand until set, about 5 minutes. Using parchment handles, remove bars from pan and set on a wire rack to cool completely. Cut into squares and serve
