- 1 batch of buttercream icing, white
- Petal dust, chocolate brown
- 1 pound fondant
- Rolling pin
- Fondant smoother
- Gel color, green, moss green and brown
- Paint brush
- Pizza cutter
- Piping tip
- Watermelon cake
Step 1: Bake the inside of the cake using this watermelon cake recipe in the Wilton Wonder Mold pan. The nice thing about the Wonder Mold pan is that it features a central heating element that helps to bake the center of the cake and keeps it from falling. Also, one tip for baking a cake with chocolate chips is to coat the chips in some flour or dry cake mix before mixing them in the batter. This helps them keep from sinking to the bottom of your pan while baking.
Step 2: Once the cake is completely cool, you can carve your cake into your desired watermelon shape.
Step 3: Place the cake on a cake plate or cutting board and ice it with buttercream icing. Try to smooth your icing as much as possible so you will have a nice flat surface for the fondant.
Step 4: Take about 1 pound of white fondant and color it lime green by mixing the white fondant with green paste coloring. Roll out the fondant, and gently rub a damp paper towel over the icing to help the fondant attach better. Cover the cake with the fondant. Smooth it down with your hands or a fondant smoother and trim the excess fondant off at the edges with a pizza cutter.
Step 5: Now it’s time to paint the rind. First, use a round decorating tip to make an indentation at the top of the cake. This will serve as a guideline for where the center is as you paint. Mix some moss green paste color with a small amount of vodka (you can also use lemon extract if necessary). With a clean paint brush that is only used for food, begin painting the food coloring onto the ring starting at the top and working your way down to the bottom. Use a sweeping, back and forth motion with the brush. At first the line may be a bit dark; let it dry for a minute and then dip your paintbrush into some water and go back over it in the same motion. The water will cause the food coloring to bleed and fade.
Continue to paint around the cake while adding more lines from the top to the bottom. There will be large spaces in between the lines, so go back to those spaces and begin to add new lines that start lower on the cake but still reach down to the bottom. Fit in as many lines as you can at varying heights to give the watermelon a realistic look.
Step 6: Since real watermelons usually have some brownish coloring on them, adding some brown to the cake helps to create a realistic look. Take another clean paint brush and dip it into some chocolate petal dust. Shake off the excess dust and tap the brush on the cake. Use a combination of tapping and sweeping motions with the brush to apply it to different spots around the cake.
Step 7: The final step is to make a realistic looking stem piece to place in the center spot on the top. Take a small ball of fondant and color it light brown with brown paste color. Roll it out and then use a large round decorating tip to cut out a circle. Attach it to the center of the cake with a small amount of water. Add another small ball of fondant to the top of the circle by attaching it with a dab of water. To add a rough look, use the tip of a knife to make indentations to it. Brush it with chocolate petal dust and then finish it by painting tiny amounts of moss green food coloring in the cut marks.
