Preheat oven to 350°F. Spray a bundt pan with non-stick spray with flour- like Baker's Joy (or use a spray like Pam and then dust the pan with flour.
Mix the oil, vanilla, sour cream, heavy cream, and egg whites. in a bowl, then mix in the boxed cake mix.
1 box of white cake mix, ½ cup vegetable oil, 2 tbs vanilla, ¾ cup sour cream, ¾ cup heavy cream, 4 egg whites
Scoop out ¾ cup cake mix into a bowl and mix in red food coloring. Scoop out another ¾ cup of cake mix into a small bowl and mix in blue food coloring.
1 teaspoon Red Gel Food Coloring, 1 teaspoon Blue Gel Food Coloring
Pour red batter into the bottom of the bundt pan. Then, carefully pour the white cake batter over the red. Pour the blue batter over the white, focusing on creating a band in the center of the white.
Bake for 40-45 minutes. The cake is done when a toothpick inserted comes out clean, and it reaches an internal temperature of 205°F on a food thermometer.
Once done baking, let the cake stand for 10 minutes, then flip onto a cooling rack and remove from the bundt pan. Allow cake to cool completely before frosting.

In a stand mixer, whip your butter on medium-high speed until the butter is light and fluffy. Then mix in the vanilla and salt.
½ cup unsalted butter, ½ teaspoon vanilla, ¼ teaspoon salt
Alternating between powdered sugar and heavy cream, mix each in until fully incorporated.
2 ½ cups powdered sugar, 2 ½ tbs heavy cream
Divide the frosting into three separate bowls. Mix in red food coloring to one bowl, blue to another, and leave the third white.
¼-½ teaspoon Red Gel Food Coloring, ¼-½ teaspoon Blue Gel Food Coloring

Place the cake on a cooling rack.
Microwave white frosting for 5 to 10 seconds, stir, and repeat until frosting is runny and a good consistency to drizzle. Drizzle over cake with a spoon or a bag with the corner cut off, using back-and-forth motions to make stripes.
Repeat with the red frosting, then the blue. Once the cake is drizzled with the blue, add sprinkles to the top and allow the frosting to set up for 30 minutes.

Tips and Tricks

*Bundt Pan Sizing- If using a 6-cup pan, remove ½- ¾ cup of white batter. If not, the cake will still bake fine, it will just rise above the edge of the pan, and you will want to slice that extra bit off, resulting in less blue (like in the pics above). A 12-cup bundt pan is quite large and will create a shorter bundt cake, but still delicious.
If you need to soften your butter fast, place it on a microwave-safe dish in the microwave, turn your microwave to 30% power, and microwave for 15-second intervals until soft.
If the frosting is too runny, add more powdered sugar, 1 tablespoon at a time, to thicken it. If it’s too thick, add more heavy cream, 1 tablespoon at a time, until it’s at your desired consistency.
