  • 1 Wire Rack For cooling
  • 1 Microwave-Safe Bowl
  • 1 Spatula For mixing and spreading

Ingredients
  

Main

  • Crisco® No-Stick Cooking Spray
  • 1 ¼ cups graham cracker crumbs
  • 6 tablespoons butter melted
  • 1 19.5 ounce box Pillsbury® Family Size Chocolate Fudge Brownie Mix
  • ½ cup Crisco® Pure Vegetable Oil
  • ¼ cup water
  • 2 large eggs
  • 1 14 ounce can Eagle Brand® Sweetened Condensed Milk
  • 1 11.5 ounce package milk chocolate chips
  • 1 13 ounce jar marshmallow creme
  • 1 cup miniature marshmallows

Instructions
 

  • Heat oven to 350 degrees F. Coat 13 x 9-inch baking pan with no-stick cooking spray. Combine graham cracker crumbs and butter in medium bowl, stirring until evenly moistened. Sprinkle 1 cup graham cracker mixture evenly into bottom of prepared pan. Prepare brownie batter according to package directions using oil, water and eggs. Spread over crumbs in pan. Bake 28 to 31 minutes or until set in center. Cool completely in pan on wire rack.
  • Microwave sweetened condensed milk and chocolate chips in medium microwave-safe bowl on HIGH 2 minutes. Stir until completely melted and smooth. Pour over brownie layer. Freeze until firm, about 1 hour.
  • Heat broiler to HIGH. Spread marshmallow creme evenly over chocolate layer. Sprinkle evenly with remaining graham cracker crumbs. Sprinkle evenly with mini marshmallows. Broil 6 inches from heat 2 minutes or until lightly browned.

Notes

For the graham cracker base, ensure crumbs are finely milled and pressed very firmly into the pan to create a stable foundation. When melting the chocolate and condensed milk, use short bursts in the microwave, stirring frequently, or opt for a gentle double-boiler method to prevent scorching. Adequate cooling of the brownie layer is paramount before pouring the chocolate ganache, as residual heat will cause it to melt and mix. Freezing the chocolate layer until truly firm is essential for clean separation and structural integrity. Broiling the marshmallows demands constant attention; they can go from golden to burnt in seconds. Position the rack 6 inches from the heat source and watch continuously, rotating if necessary, to achieve even, golden-brown tops. For impeccable presentation and clean cuts, ensure the bars are thoroughly chilled before slicing with a hot, sharp knife.
