Cake or canvas? You don’t need to be an artist to create this sweet masterpiece. Simply wrap a 4-layer cake in white fondant, mix together food coloring and water, and start painting. Apply gold leaf for a special finishing touch.
1 cup store-bought vanilla frosting (175 g)
1 chocolate cake
cornstarch, for dusting
1 lb white fondant (455 g)
1 drop forest green gel food coloring
1 drop burgundy gel food coloring
1 drop purple gel food coloring
3 teaspoons water
fondant pres, optional
1 craft sea sponge
How to Make It
Place a cake round on a cake turntable and dab 1 teaspoon of frosting in the center of the round. Place the chocolate cake on the cake round.
Using an offset spatula, cover the cake with the vanilla frosting. Use a cake scraper to smooth the frosting in a thin, even layer. Fill any gaps between the cake layers with more frosting, scraping as needed. Chill the cake while you prepare the fondant.
On a surface lightly dusted with cornstarch, knead the fondant until pliable, about 2 minutes. Shape the fondant into a 4-inch square, then roll out with a rolling pin to a circle about ⅛ inch thick and 12 inches wide.
Drape the fondant over the chilled cake so it hangs evenly over all sides. Gently press the fondant against the cake with the palms of your hands or a fondant press, moving in a circular motion and stretching the fondant down and away from the cake as needed. This motion will help the fondant cover the cake completely and remove any creases. Trim the excess fondant and use your hands or the fondant press to remove any air bubbles.
Cut a craft sponge into 3 equal pieces. Completely wet each piece, then wring out until barely damp.
Add the forest green, burgundy, and purple food colorings to separate small bowls, then pour about 1 teaspoon of water into each dish. Use a small spoon or paint brush to mix the colors and water together.
Lightly dip a sponge into the first color and gently dab it onto the cake, creating a concentrated color. Dip a paintbrush in water and brush over the sponged area to dilute the color a bit. Repeat this process with the remaining colors. Use a paper towel to blot the colors, smearing and smudging in areas, to create a watercolor effect. Be careful not to let the color dry before using the paintbrush and paper towel to smudge.
While the cake is still damp, use the gold leaf to decorate as desired.
