                Preheat oven to 325 degrees F. Line an 8x8-inch baking pan with aluminum foil, leaving some overhang for easy removal. Lightly spray the foil with cooking spray.

                Place butter and chopped unsweetened chocolate in a medium saucepan over medium-low heat. Stir constantly until completely melted and smooth. Remove from heat.
              
              
              
                03 - 
                Whisk the sugar into the chocolate mixture until well combined.
              
              
              
                04 - 
                Whisk in the eggs and vanilla extract until the mixture is smooth and glossy.
              
              
              
                05 - 
                Stir in the flour and salt just until combined. Do not overmix.

                Spread the brownie batter evenly in the prepared pan. Bake for about 40 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

                While the brownies are still warm, spread the marshmallow fluff/creme evenly over the top. The heat from the brownies will help make the marshmallow easier to spread.
              
              
              
                08 - 
                Place the shredded coconut, cornstarch, and pink food coloring in a food processor. Pulse several times until the coconut is slightly chopped and the pink color is evenly distributed throughout.
              
              
              
                09 - 
                Sprinkle the pink coconut mixture over the marshmallow layer, gently pressing it into the marshmallow creme to adhere.
              
              
              
                10 - 
                Allow the brownies to cool completely before lifting out of the pan using the foil overhang. Cut into 9 squares using a sharp knife, wiping the blade clean between cuts for the neatest result.
