INGREDIENTS

White cake mix: use your favorite brand.

Red and white food coloring gel: this will make the cake colorful. You just need a few drops of each color. You can add more or less drops depending on how light, dark, or bright you want your colored layers to be.

Frosting: I used canned vanilla frosting but you can use homemade frosting.

HOW TO MAKE 4th OF JULY CAKE

MAKE CAKE BATTER. In a large bowl, mix together cake mix, eggs, oil, and water until combined with an electric mixer. Scrape down the sides of the bowl occasionally.

DIVIDE CAKE BATTER. Divide batter into 3 bowls. In one bowl add 3-5 drops of red food color and stir with a spoon until blended and combined. Add the blue food coloring to the other bowl. Add more or less food coloring depending on how light, dark, or bright you want your colors to be.

ADD FOOD COLORING. Pour the red-colored batter into the bottom of the prepared bundt pan. Then slowly pour the white batter on top, and then carefully pour the blue batter on top. It’s OK if any of the cake batter colors overlap. Bake for 40-45 minutes or until a toothpick inserted comes out clean.

BAKE. Let the cake sit for at least 10 minutes, and then remove it from the bundt pan. If the cake is sticking to the bundt pan, gently tap the edges of the bundt pan or scrap the edges as much as you can with a spatula. Let the cake sit on the cooling rack until completely cooled.

HOW TO FROST 4th OF JULY CAKE

ADD TO BOWLS. Divide the frosting into 3 microwavable small bowls. Microwave each bowl for 15-20 seconds or until thin enough to drizzle over the cake.

COLOR THE FROSTING. Add a few drops of red food gel to one of the bowls and stir until combined. Then add a few drops of blue food gel to the bowl and stir until blended.

ADD FROSTING TO CAKE. This is where the ‘firecracker’ part comes in making this look like a Firecracker Cake! Drizzle each frosting color over the cake with a spoon until you run out of frosting. Add sprinkles to the top and let the cake sit for about 20 minutes to let the frosting harden. Slice and enjoy!

RECIPE TIPS & VARIATIONS

Instead of using frosting on top, you can use melted white chocolate.

Bake the cake the day before so all you have to do is frost the cake the next day. This will save you time so you don’t have to wait for the cake to cool.

Frosting: you can make your own frosting from scratch or use other canned frosting flavors such as cream cheese frosting, buttercream, vanilla, or any other flavor that’s white.

You can switch out the red, white, and blue colors and use any color combination that you want. You can also add more cake layers by using less cake batter in each bowl. Make this a rainbow cake for a birthday or celebration.

Some other topping ideas are red, white, and blue-themed M&Ms, edible glitter, star candles, and other red, white and blue-themed candy.

LEFTOVERS & STORAGE

Cover any leftovers with plastic wrap or store in an airtight container. The cake will stay fresh for up to 4-5 days when stored in a cool area.

If the cake seems to harden after a few days, you can heat the cake in the microwave for a few minutes to soften and warm. The frosting will slightly melt but it will be just as delicious.
