Creating a stunning Strawberry Ice Cream Cake is simple when you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.

2. Prepare Cake Batter: In a large mixing bowl, combine the cake mix, vegetable oil, eggs, and water. Mix according to the package instructions until smooth.

3. Bake Cake: Divide the batter evenly between the prepared cake pans. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean.

4. Cool Cakes: Once baked, remove the cakes from the oven and allow them to cool in the pans for about 10 minutes. Then transfer the cakes to wire racks to cool completely.

5. Layer Ice Cream: While the cakes are cooling, take the softened strawberry ice cream and spread an even layer of it in a springform pan or a round cake pan lined with plastic wrap.

6. Freeze Ice Cream Layer: Place the pan in the freezer for about 1 hour, or until the ice cream layer is firm.

7. Assemble the Cake: Once the ice cream layer is firm, place one of the cooled cake layers on top. Spread softened vanilla ice cream over the cake layer, covering it completely.

8. Add Strawberries: Distribute the sliced strawberries evenly over the vanilla ice cream layer.

9. Finish with Cake: Top with the second cake layer and gently press it down. Cover the entire assembled cake with plastic wrap and return it to the freezer for at least 3 hours or overnight.

10. Serve: When ready to serve, remove the cake from the freezer. Allow it to sit at room temperature for about 10 minutes before slicing.
