Strawberry Cake and Frosting

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease and flour three 9-inch round pans.

Step 2
In a large bowl, stir together cake mix, gelatin mix, and flour. Make a well in the center and pour in water, oil, and eggs. Stir in 1/2 of the strawberries. Beat on low speed until blended; scrape down sides of the bowl and beat 4 minutes on medium speed. Pour batter into prepared pans.

Step 3
Bake in the preheated oven for 30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow cake to cool.

Step 4
To make strawberry frosting: In a large bowl combine butter, confectioners' sugar, and remaining frozen strawberries. Beat on high speed until creamy.
