Chocolate Peanut Butter Bars
Vegetable oil, cooking spray
2 cups all-purpose flour
1 1/4 teaspoons coarse salt
8 ounces (2 sticks) unsalted butter, softened
3/4 cup packed light-brown sugar
12 ounces milk chocolate, melted
1 cup creamy peanut butter
- Coat a 9 1/2-inch square baking pan with cooking spray. Line with parchment, leaving a 2-inch overhang on 2 sides, and coat parchment with spray.
- Sift flour and salt into a medium bowl. Beat butter with a mixer on medium-high speed until fluffy, 3 to 5 minutes. With the mixer running, add sugar, and beat until pale and fluffy, about 2 minutes. Reduce speed to low. Add flour mixture, beating until just incorporated. Press dough evenly into pan. Cover, and refrigerate until firm, about 20 minutes.
- Preheat oven to 300 degrees. Bake shortbread until golden brown and firm in center, 45 to 50 minutes. Let shortbread cool in pan on a wire rack.
- Use parchment to unmold shortbread from pan, and trim edges to create a square. Spread peanut butter evenly on shortbread. Carefully pour melted chocolate over the peanut butter and spread evenly to cover. Cut shortbread into 1 1/2-inch squares. Shortbread will keep, covered, for up to 3 days.
Makes about 36 squares.
