Ingredients

Scale

For the Cake:

1 box white cake mix (Duncan Hines preferred)
1 cup whole milk
2/3 cup vegetable oil (Wesson)
3 eggs (room temperature)
Yellow gel food coloring
Pink gel food coloring

For the Gelatin Soak:

6 oz blue gelatin (Jell-O brand)
2 1/2 cups boiling water

For the Frosting:

16 oz vanilla frosting
1 cup whipped topping (thawed, e.g., Cool Whip)
1 teaspoon vanilla extract
1/8 teaspoon fine sea salt

Instructions

Prepare Pans and Make Two-Tone Cake Batter: Preheat the oven to 350°F. Grease and flour two 9-inch round cake pans. In a large bowl, combine cake mix, whole milk, oil, and eggs, stirring just until combined without overmixing. Divide the batter evenly between two bowls. Add yellow gel food coloring to one bowl and pink gel food coloring to the other, mixing each until fully colored.
Bake the Colored Cake Layers: Pour each colored batter into its prepared cake pan. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Let cakes cool in pans for 10-15 minutes, then turn out onto wire racks to cool completely.
Prepare the Blue Gelatin Base: Dissolve the blue gelatin in 2 1/2 cups boiling water, stirring until fully dissolved (about 2 minutes). Set aside to cool to room temperature—letting it cool prevents melting the cake when poured.
Poke Holes and Fill with Gelatin: Once cakes are cooled, use a wooden toothpick or skewer to poke about 30-40 holes in each layer, spacing them evenly and poking about halfway through the cake. Slowly pour the cooled blue gelatin over the poked cakes, allowing it to seep into the holes and pooling any excess on top. Refrigerate both cake layers for at least 4 hours until gelatin is fully set and firm.
Make the Frosting Mixture: In a medium bowl, combine vanilla frosting, thawed whipped topping, vanilla extract, and fine sea salt. Stir until smooth and fluffy to create a light, whipped texture.
Assemble and Frost the Cake: Place one chilled cake layer on a serving plate. Spread a generous layer of frosting mixture over the top. Place the second cake layer on top, then frost the sides and top of the cake with remaining frosting. Refrigerate the assembled cake for at least 30 minutes before serving to allow the flavors to meld and structure to stabilize.

Notes

Always let the gelatin cool to room temperature before pouring to avoid melting and gummy cake texture.
Be sure to poke enough holes deep enough (about halfway through) for even gelatin distribution.
Chill the cake fully for at least 4 hours before frosting to prevent frosting from mixing with gelatin and turning blue.
Optional: Use gel food coloring to tint the cake batter for more vibrant layers.
Substitute vegetable oil with canola, melted coconut oil, or melted butter for variations in flavor.
Use yellow cake mix as a substitute if preferred, but white cake mix shows colors best.
Store the cake covered in the refrigerator for up to 4 days; do not freeze as gelatin and whipped topping textures degrade when thawed.
Serve chilled for best texture and appearance. Pair with vanilla ice cream or fresh berries if desired.
