Four Layer Strawberry Filled Cake

1 pkg yellow cake mix
1/3 cup oil
3 eggs
1 tsp. vanilla
1 cup milk
1/2 cup sour cream

Preheat oven to 350 degrees. Mix all ingredients and pour into 2 round cake pans. Bake 25-30 minutes or until toothpick inserted in center comes out clean. Cool completely and split each layer making a total of 4 layers

Filling:
1 cup sugar
1 cup sour cream
1 cup strawberries

Mix sugar and sour cream until well blended. Fold in strawberries. Put 1/3 between each layer.

Frosting:
2 cans pre-made WHIPPED Vanilla frosting
4 oz. cream cheese softened

In a bowl, whip frosting and cream cheese until completely blended and fluffy, about 3-4 minutes. Frost cake. Garnish with strawberries.

Changes - Use WELL drained pineapple, blueberries or raspberries instead of strawberries. Add nuts to cake and/or frosting. Add my favorite, coconut to icing and/or filling.
