Preheat the oven to 350 degrees Fahrenheit.

Prepare cake mix based on the package instructions.

Separate the batter equally into 3 bowls.

Leave one bowl white. Add the red gel food coloring to one bowl until it is a deep red color.

Add the green gel food coloring to the 3rd bowl until it is the vibrant green color.

Spray a bundt pan with non-stick spray.

Spread the uncolored cake mix into the bottom of the bundt pan.

Dollop the red and green batter on top. Then use a knife to gently swirl the colors together. Do not over swirl or you’ll change the color of the cake batters.

Bake the cake for 45-55 minutes until a toothpick inserted into the center of the cake comes out clean.

Once cooked, allow it to cool for 10 minutes and then flip the cake onto a serving platter or wire rack to cool completely.

While the cake is cooling, prepare the frosting by mixing the frosting ingredients together in a medium size bowl. Start with 1 tablespoon of milk and gradually add more water until the frosting is an easy pourable consistency.

Once the cake has cooled, pour the frosting over the top and let it drizzle down the sides of the cake slightly.

Top with the Christmas sprinkles. Then the cake is ready to slice, serve and enjoy!
