1. Bake the Vanilla Cake:

Preheat your oven to 350°F (175°C). Prepare the vanilla cake mix according to the package instructions, using the eggs, water, and vegetable oil. Pour the batter into a greased and floured 9-inch round cake pan. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Let the cake cool completely.

2. Prepare the Ice Cream Layers:

While the cake cools, let the ice cream soften slightly at room temperature for 5-10 minutes. This makes it easier to spread.

3. Slice the Cake:

Once cooled, use a serrated knife to slice the cake in half horizontally. Place one layer on a serving plate.

4. Add the Ice Cream Layers:

• Spread the softened strawberry ice cream evenly over the first cake layer.
• Place the second cake layer on top, then spread the mint chocolate chip ice cream over it.
• Add the blueberry ice cream as the final layer, smoothing it out with a spatula.
• Freeze the assembled cake for at least 2 hours to set.

5. Make the Whipped Cream Frosting:

In a large mixing bowl, whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Divide the whipped cream into separate bowls and add a few drops of food coloring to each to create a rainbow palette.

6. Frost the Cake:

Remove the cake from the freezer and frost it with the whipped cream. Blend the colored whipped cream to create a swirled, magical effect. Use a spatula to smooth the top and sides.

7. Decorate the Cake:

Sprinkle edible glitter and colorful sprinkles over the frosted cake. Add a unicorn cake topper if desired for an extra whimsical touch.

8. Serve and Enjoy:

Slice the cake into wedges and serve immediately for a fun and delightful treat.
