For the cake:
1 18.25-ounce box white cake mix
1 3-ounce box strawberry-flavored instant gelatin
1 15-ounce package frozen strawberries, thawed and pureed
4 large eggs
1/2 cup vegetable oil
1/4 cup water
For the frosting:
1/4 cup butter, softened
1 8-ounce package cream cheese, softened
1 10-ounce package frozen strawberries, thawed and pureed
7 cups confectioners’ sugar
1. Preheat oven to 350 degrees. Lightly grease a 13 x 9-inch cake pan.
2. In a large bowl, combine cake mix and gelatin. Add pureed strawberries, eggs, oil, and water; beat at medium speed with an electric mixer until smooth. Pour into prepared pans, and bake for 25 to 30 minutes, or until a wooden pick inserted in the center comes out clean. Cool completely.
3. To make the frosting, beat the butter and cream cheese at medium speed with an electric mixture until smooth and creamy. Beat in the strawberries. Gradually add confectioners’ sugar to desired thickness, beating until smooth.
4. Spread frosting over cooled cake. Store leftovers (if there are any!) in the refrigerator.
