Suzy-Q Brownies

Suzy-Q Brownies For the brownies: 2 boxes fudge brownies I like Duncan Hines Decadent Fudge 4 eggs ¼ cup water ⅔ cup vegetable oil For the filling: 1 cup (2 sticks)salted butter softened to room temp 1 cup powdered sugar ½ tsp vanilla extract 1 7.5 oz jar marshmallow creme Preheat oven to 325f degrees. Spray the bottom of a 10x15x2 baking dish (also called a lasagna pan) with nonstick cooking spray. In a large bowl, prepare both boxes of brownies (mixing together brownie mix, eggs, water and oil.) Pour the brownie mixture into the prepared baking dish. Bake for about 35-40 minutes until center is set. Allow brownies to cool completely Loosen the edges of the brownie from the sides of the pan with a butter knife. Invert pan onto a large cutting board to release the brownie from the pan. Carefully cut the brownie in half, horizontally. Note: this is easiest if you spray your knife with nonstick cooking spray. Also, if the edges of your brownie got a bit crunchy, cut the edges off first. In a separate bowl, prepare filling. Using an electric mixer, cream butter. Then add powdered sugar and vanilla extract. Stir again. Finally mix in marshmallow creme. Evenly spread filling mixture on one half of the brownie. Carefully place the other half of the brownie on top. Then cut into 15 squares.
