The recipe for Peanut Butter Sheet Cake was sent by Brenda Jackson, Garden City, Kansas. "A minister's wife gave me this recipe...and my family loves it," she writes. "My daughter, Stephanie, shared the treat with members of her Bible study group (pictured below, she's in the center of the back row)."
I didn't have any luck finding a peanut butter-filled chocolate cupcake (my two favorite flavors), so I made my favorite chocolate cupcake recipe and experimented with the filling until I found one I liked. —Julie Small, Claremont, New Hampshire
