Makes 24 cupcakes
1 "Family Size" box Pilsbury Fudge Brownies
1/4 cup water
1/2 cup vegetable oil
20 graham crackers
1 stick unsalted butter, melted
1/2 cup sugar
1 bag unsweetened mini chocolate chips
2 cans Marshmallow Fluff
2 Hershey Bars (optional)
Preheat oven to 350 degrees F and place 24 cupcake liners in muffin tins. Prepare brownie mix according to package directions for "cake like" brownies (3 eggs instead of 2). Set aside batter.
Combine graham crackers and sugar in a food processor or blender and pulse until the crackers are crushed into small, even crumbs. Add melted butter and pulse again until mixture is crumbly but becomes firm when pressed.
Drop 1 Tablespoon of graham cracker mixture into the bottom of each muffin cup and use a small glass to press them down until evenly spread and firm. Sprinkle 1 teaspoon of chocolate chips on top of graham crust in each cupcake. Place cupcake pans in the oven for about 5 minutes to firm graham crusts and begin melting the chocolate.
Remove pans from oven and fill each muffin cup with brownie batter until 3/4 of the way full. Sprinkle each cupcake with another teaspoon of chocolate chips and a Tablespoon of graham mixture. Place tins in the oven and bake for approximately 20 minutes, or until a toothpick inserted into the center cupcake comes out clean.
Place muffin tins on a rack until the cupcakes are cooled. Meanwhile, fill a pastry bag or quart-sized zipper bag with marshmallow fluff. When cupcakes have cooled, pipe a small amount of frosting on top of each cake. Do not overfrost, as the fluff will ooze as it settles onto the cakes.
Turn oven to broil setting and place muffin tins, one at a time, under broiler approximately 1 inch from the flame. Watch the cakes closely to make sure they puff and brown but do not burn. This may only take a few seconds! Shift tin as needed to make sure the marshmallow browns evenly. Repeat with the second tin. If desired, once cupcakes are completely cooled, top each with a piece of Hershey's chocolate.
Serve with lots of napkins....or a hose.
