Here is one that my work buddy gave me in 1984 and I love it, but it does make enough for at least 12 people.
Fran's Banana Split Cake
2 cups graham cracker crumbs
¼ cup melted butter
¼ cup sugar
Combine crumbs, butter & sugar and mix well. Press into a 13 x 9 x 2 " pan and chill for 1 hour.
2 cups icing sugar
½ cup softened butter
1 egg
1 tsp vanilla
Cream icing sugar and butter; add egg and vanilla. Blend well and spread over crumb mixture and chill for 1 hour longer.
4 bananas
blueberries/strawberries or raspberries
2 cups whipped cream
2 small tins pineapple tidbits (about 3 cups total estimate)
1 cup chopped walnuts
Slice bananas and place on cake. Place a layer of berries over the bananas. Drain the pineapple well and place a layer over the berries. Spread the whipped cream on top and cover with walnuts. Chill.... just typing this makes me hungry for some! Enjoy!
