1 box (15-oz) brownie mix (not fudge-style)
1 pint vanilla ice cream
1/2 cup chopped nuts

Allow to cool completely on a wire rack before continuing with the recipe.
Cut the completely cooled brownies into 2-inch squares. Freeze (single layer) approximately 10 minutes. Let ice cream stand at room temperature to soften while brownies are in freezer.
Place one brownie square on a piece of plastic wrap about 6-inches in size. Top with ice cream then another brownie to made sandwich. Repeat until all brownies are used.
Place the nuts in a small plate or saucer. Press the nuts around the edges of the ice cream. Loosely wrap in the plastic wrap and freeze to reharden ice cream before serving.
