Chocolate Peanut Butter Brownies

Preheat oven to 350 degrees F. For crust, in a medium bowl, combine crushed graham crackers, the 1/4 cup sugar, and the finely chopped peanuts. Stir in the 1/2 cup melted butter. Press mixture evenly into the bottom of an ungreased 11x7x1-1/2-inch baking pan. Bake for 5 minutes; cool.

For filling in a heavy large saucepan, combine the 1/2 cup butter and the chocolate; heat and stir over low heat until melted. Remove from heat. Add the 1 cup sugar, the eggs, and vanilla to chocolate mixture; stir just until combined. Stir in flour and peanut-butter-flavored pieces. Spread evenly over crust.

Bake for 20 minutes. Cool in pan on a wire rack. Spread with Peanut Butter Frosting. Cut into bars. Place a peanut half on each bar. Makes 20 brownies.
