Peanut Butter and Milk Chocolate Chip Brownie Bars

Who doesn't love chocolate and peanut butter? I found this recipe on christyskitchencreations.blogspot.com and thought they looked scrumptious. I made them last night to take to a picnic today. I resisted and haven't tasted them yet.

6 tablespoons butter or margarine, melted
1 1/4 cups sugar
2 teaspoons vanilla extract, divided
3 eggs
1 cup plus 2 tablespoons all-purpose flour
1/3 cup Hershey's Cocoa
1/2 teaspoon baking powder
1/2 teaspoon salt
1 can (14 ounces) sweetened condensed milk
1/2 cup Reese's Peanut Butter
1 cup Hershey's Milk Chocolate Chips, divided
1 cup Reese's Peanut Butter Chips, divided
3/4 teaspoon shortening (do not use butter, margarine, spread or oil)

1. Heat oven to 350 degrees. Grease 13x9x2-inch pan.

2. Stir together butter, sugar and 1 teaspoon vanilla in large bowl. Add 2 eggs; stir until blended. Stir together flour, cocoa, baking powder and salt; add to egg mixture, stirring until well blended. Spread evenly in prepared pan. Bake 20 minutes.

3. Meanwhile, stir together sweetened condensed milk, peanut butter, remaining egg and remaining 1 teaspoon vanilla. Pour evenly over baked layer. Set aside 1 tablespoon each milk chocolate chips and peanut butter chips; sprinkle remaining chips over peanut butter mixture. Return to oven; continue baking 20 to 25 minutes or until peanut butter layer is set and edges begin to brown. Cool completely in pan on wire rack.

4. Stir together remaining milk chocolate chips, remaining peanut butter chips and shortening in small microwave-safe bowl. Microwave at HIGH (100%) 30 seconds; stir. If necessary, microwave at HIGH an additional 15 seconds at a time, stirring after each heating, until chips are melted and mixture is smooth when stirred. Drizzle over top of bars. When drizzle is firm, cut into bars. (I didn't wait that long!) Store loosely covered at room temperature.
