Instructions
Cake:
- Preheat oven to 350 degrees F (175 degrees C). Coat three 8-inch round cake pans with baking spray.
- In a medium bowl, whisk together 2 ½ cups flour, gelatin mix, baking powder, salt, and baking soda.
- In a stand mixer fitted with the paddle attachment, beat the softened butter at medium speed until creamy. Gradually add sugar and beat until light and fluffy.
- Add eggs, one at a time, beating just until blended. Scrape down sides of the bowl after each addition.
- Alternately add the flour mixture and buttermilk to the butter mixture, beginning and ending with the flour mixture. Beat at low speed until just blended after each addition.
- Beat in vanilla extract and red food coloring gel until blended.
- Toss chocolate chips with 1 tablespoon flour in a small bowl, then gently fold into the batter.
- Divide the batter evenly among the prepared cake pans.
- Bake in the preheated oven until a wooden pick inserted in the center comes out clean, about 28 to 32 minutes.
- Cool the cakes in the pans on a wire rack for 10 minutes, then remove them from the pans and cool completely for about 1 hour.
Frosting:
- Beat the softened butter and salt with a stand mixer fitted with a paddle attachment on medium speed until creamy, about 3 minutes.
- Beat in vanilla extract.
- Gradually add powdered sugar alternately with the cream, beating on low speed until completely incorporated and smooth, about 2 minutes.
- Increase mixer speed to medium-high and beat until the mixture is smooth and fluffy, about 2 to 3 minutes.
- Reserve 1/3 cup of the frosting in a small bowl for later use.
- Remove 2 cups of the frosting to a medium bowl and stir in enough red food coloring until desired shade of red.
- Tint the remaining frosting with green food coloring gel until you achieve the desired shade of green.
Assemble Cake:
- Place one cake layer on a serving platter or cake stand. Spread the top with 2/3 cup of the red frosting.
- Top with the second cake layer and spread the top with another 2/3 cup of the red frosting.
- Place the remaining cake layer on top and spread the top with the remaining red frosting, leaving a 1/2-inch border around the edge.
- Frost the sides of the cake with the green frosting.
- Place the reserved plain frosting into a piping bag or a zip-lock bag with a 1/4-inch hole cut in the corner.
- Pipe the plain frosting around the top edge of the cake, filling in the 1/4-inch border.
- Sprinkle the top of the cake with miniature chocolate chips to resemble watermelon seeds.
