Watermelon Cake Tutorial
What You will need to make Watermelon Cake
- Cake Turntable Stand
- Offset spatula
- Cake Comb
- Piping bags
- Gel Colors (Red, Deep Pink, Leaf Green, Bright Green)
- 2D Piping Tip
- Black Sprinkles (you can also find some at your local baking store & craft store)
- Super White Chocolate Candy Melts (Sweet Tooth Fairy Meltables are another great option)
- Heavy Cream
- Sprinkles with your preferred colors (My Faves are from Fancy Sprinkles & Sweetapolita)
Watermelon Cake Design Instructions
- Bake your delicious cake recipe or a summer cake recipe using a stand mixer and pour the cake batter into the 6-inch round cake pans.
- Let the cake cool for 10 minutes then take the cake layers out of the pans.
- Cut the top using a serrated knife or a cake lever if there is a significant dome.
- Make your preferred buttercream.
- Use four separate bowls to color the buttercream green, lime green, deep pink, and white (No coloring needed).
- I used a small drop of red to the deep pink buttercream to get darker deep pink.
- Crumb coat the cake with white buttercream covering all of the naked spots using an offset spatula.
- Use the cake comb to smooth the cake. Fill in the holes with buttercream until you get a smooth coat.
- Place the cake in the fridge until cold.
- Place all of the buttercreams in piping bags and snip the tip off large enough to pipe on the cake.
- Start with the dark green and start piping at the bottom of the cake.
- Do one row of lime green above the green buttercream.
- Apply one row of white buttercream above lime green buttercream.
- Pipe the deep pink on the rest of the cake.
- Use the cake scraper to smooth the cake and blend the colors.
- Pipe in the gaps with the same color buttercream.
- Continue smoothing the cake with the cake scraper until you are satisfied with the results.
- Pipe the top of the cake with the deep pink buttercream and smooth with the small offset spatula.
- Place it back in the fridge to let the cake firm up for 15 minutes or until cold.
- Run a knife under the hot water and cut off the excess buttercream on the top to make sharp edges.
White Cake Drip Instructions
- Place 3 oz of white chocolate melts in a small bowl and pour 1 oz of heavy cream
- Microwave for 30 seconds and 15-second intervals until melted.
- Let it rest for 5-10 minutes. You don’t want it to be too hot to melt the cake or too cold. It should be warm to the touch.
- Pour it into a tipless piping bag (my preferred piping bag for drips but a regular small piping bag should work)
- Apply chocolate to the cake starting on the top and then on the sides using various pressures while squeezing the piping bag. I usually count up to 5-7 seconds per drip. Less time if the chocolate is runnier than usual.
How To Do Watermelon Toned Buttercream
- Lay out some cling wrap. Using the leftover green, lime green, and deep pink and pipe alternating the colors like below. Repeat for another layer on top of the colors.
- Wrap the cling wrap and snip off the end with a pair of scissors.
- Fit a piping bag with a 2D piping bag and put the cling-wrapped buttercream into the piping bag.
- Start piping buttercream swirls on the top of the cake. Apply sprinkles on the top of the swirls as desired.
- Apply the black sprinkles to the cake for the final touch!
