Cranberry Refrigerator Dessert Recipe

Grind 2 cups of cranberries in a food processor. Dice the banana and combine with the cranberries and 1/2 cup of sugar. Set aside. Combine 2 cups of vanilla wafer crumbs and 6 tablespoons of melted butter. Place 1/2 of the crumb mixture on the bottom of a 9x9x2 pan or dish. Cream 1/2 cup butter and 1 cup of sugar until fluffy. Add 1 egg and beat until fluffy. Fold in 1/2 cup of walnuts. Spread this mixture over the crumb mixture. Then top this with the cranberry mixture. Top with the Cool Whip and remaining vanilla wafer crumb mixture. Chill 6 hours or overnight.
