Learn how to make and decorate this awesome watermelon cake! Watermelon flavored cake with chocolate chip 'seeds' and decorated with buttercream frosting. Perfect for a summer get together, bbq or picnic!
What you'll need:
1 (15-16 oz)box white cake mix (and ingredients needed to make according to package directions)
1 (3 oz) box watermelon Jell-O gelatin (watermelon flavor is only available in the summer so stock up!)
1/4 cup mini chocolate chips plus 2 Tbsp, divided (use only mini as regular chips will sink)
buttercream frosting (either homemade or premade vanilla frosting)
red and green food coloring
In a stand mixer or large bowl with an electric mixer, combine dry cake mix and Jell-O powder. Add in remaining ingredients to make cake batter according to package directions (usually water, oil and egg whites). Beat on medium speed for one full minute to make sure gelatin is dissolved. Fold in mini chocolate chips that have been lightly oiled and floured (important to prevent them from sinking to the bottom). Pour batter into (2) 8" greased and floured, parchment lined cake pans. Bake according to package instructions. Let cool 10 minutes and then turn out onto wire racks to cool completely.
With your buttercream frosting, divide in half and color one half red. With the other half, divide in half again and color one half green and leave the other half white. Place on cake onto a cake plate and spread half of the red frosting on top. Place the other cake on top and press firmly to set the cake. Using the white frosting, put a crumb coat on the sides only, reserving about 2 Tbsp. Let firm up in the freezer before moving on. Frost the sides using the green frosting and bring the frosting onto the top edge by 1/2". Using the remaining red and spread out to meet the green frosting on top. Using a zip top bag with the corner snipped with the reserved white frosting, pipe a white line between the red and green frosting. Place more mini chocolate chips on top for more 'seeds'. Let cool completely before cutting and serving. Serves 12. Enjoy!
