Another gem from my mom's former co-worker, the Domestic Goddess! Frozen strawberries do not work in this recipe.
- Combine cake mix, eggs, sugar, water, canola oil, and 8 oz sour cream. Bake in three layers at 350 degrees for 20-25 minutes, or until done.
- Combine powdered sugar and 16 oz sour cream. (Do not use mixer.) Fold in Cool Whip, then strawberries.
- Use strawberry mixture as both filling and frosting.
- Store in refrigerator.
