Combine white cake mix, strawberry jello and flour. Add oil, water, eggs and 3/4 c strawberries. Do not over mix.
Pour into 2 greased and floured 8" cake pans. Bake 35 minutes.
Once cakes have completely cooled make icing by combing margarine, confectionary sugar and enough strawberries to spread. Be careful that you do not use too many strawberries as the icy will become runny. Ice cakes and enjoy!
