Double Strawberry Cake

1 cup strawberry puree
4-5 cups powdered sugar
Preparation
Preheat oven to 350 degrees F and grease a 9×13-inch baking dish.
In a large bowl, combine cake mix, flour, and jello powder and sift to combine. Add eggs, oil, water, vanilla, and 1 cup strawberry puree and mix until smooth.
Transfer batter to the prepared baking dish and bake for 35-40 minutes or until an inserted toothpick comes out clean. Allow cake to fully cool as you prepare the frosting.
Frosting: In a large bowl, mix together cream cheese butter, and strawberry puree until smooth. Slowly add powdered sugar until frosting is desired thickness. Refrigerate until cake is ready to frost.
