Ooey-Gooey Chocolate-Peanut Butter Brownies

Cooking Light, September 2000
Yield: 24 brownies (serving size: 1 brownie)

Ingredients:
3/4  cup  fat-free sweetened condensed milk, divided
1/4  cup  butter or stick margarine, melted and cooled
1/4  cup  fat-free milk
1  (18.25-ounce) package devil's food cake mix
1  large egg white, lightly beaten
Cooking spray
1  (7-ounce) jar marshmallow creme (about 1 3/4 cups)
1/2  cup  peanut butter morsels

Preparation:
Preheat oven to 350°.

Combine 1/4 cup condensed milk, butter, and next 3 ingredients (butter through egg white) in a bowl (batter will be very stiff). Coat bottom of a 13 x 9-inch baking pan with cooking spray. Press two-thirds of batter into prepared pan using floured hands; pat evenly (layer will be thin).

Bake at 350° for 10 minutes. Combine 1/2 cup condensed milk and marshmallow creme in a bowl; stir in morsels. Spread marshmallow mixture evenly over brownie layer. Carefully drop remaining batter by spoonfuls over marshmallow mixture. Bake at 350° for 30 minutes. (note: I strongly advise you to only bake them for about 20 minutes to keep them gooey) Cool completely in pan on a wire rack.
