It’s summertime again. Actually, it is the end of May and summer is still 3 weeks away but if you live in South Florida summer began months ago. I needed a cake for a dinner party this weekend and said to myself, “Self, what springs to mind when you think about summer?” After a moment, I replied, “Well, after a long hot winter I want to fall into a cool, refreshing cake that shrieks summer.” I decided on a Watermelon Cake. It doesn’t taste like watermelon (it is actually a white cake dyed reddy/pink) but sure looks like one. 

Bake the cake in a greased and flowered Wilton Egg Pan (because I own one.) Fill the pan to within an inch of the top and be sure to put a cookie sheet under it while baking as it will overflow the pan. My oven is slow so I baked it for an hour at 350 F. Remove from the oven and let cool completely. Trying to remove the cake while warm will destroy it.

After the cake is completely cool, (I know, the cake is very cool, but in this case I mean the temperature) cut the excess cake along the edge of the Egg Pan to make a perfectly flat side then turn it out onto a wire rack. If necessary loosen the edges of the cake from the pan with a flexible spatula.

Frost the cake with a heavy layer of white crusting butter cream frosting (I made a double recipe of the below) and place in the freezer. When the frosting is set, about an hour, coat with another layer of white frosting making it as smooth as possible, returning to the freezer. This makes the thicker white watermelon rind. While the twice white frosted cake is again setting add some green food coloring to the remaining frosting. This green should be the background green of the watermelon, not the dark green lines. Add a little additional milk to reduce the viscosity, or to the non-scientists among us, reduce the “thickness.” After the frosting on the cake is set, smooth a layer of the light, thinner green frosting over the entire cake and return to the freezer. After the now light green cake is set, remove from the freezer and smooth the surface. I like to use a latex gloved hand wetted by holding it under the faucet. A bowl of water would also work but then you have to clean another bowl. You will have to clean and re-wet your hand a few times to smooth the entire cake. Once the light green frosted cake is smooth, guess what? Return it to the freezer to set.
Remove the smooth light green frosted cake from the freezer and paint the dark green stripes. I used Duff green airbrush dye and a 3/8″ brush (because I own them.) If you are the artistic type with a good eye and imagination this is no biggie. If you are the more analytical, fallen chemist type, set your iPad with a picture of a watermelon next to your cake and copy to the best of your limited artistic ability.

BTW, here is a tip I found online: to disperse the chocolate chips and not have them settle to the bottom of the cake batter mix them into the flour mixture being sure the are well coated with flour. This seems to help them “float” in the cake batter as it bakes.

Here is another tip: don’t let the cake with the thick frosting warm up in the car ride to your party. Soften or melted rind signficantly affects the overall impression of the cake.

Recipe: Heavenly White (Watermelon Colored) Cake

Ingredients

• 2 3/4 cups sifted cake flour
• 4 teaspoons baking powder
• 3/4 teaspoon salt
• 4 egg whites ( or substitute)
• 1 1/2 cups white sugar
• 3/4 cup butter
• 1 cup milk
• 1 teaspoon vanilla extract
• 1/2 cup of chocolate chips
• Red dye

Directions

1. Measure sifted flour, baking powder, and salt; sift together three times.
2. Add chocolate chips and mix being sure the chips are well coated with the flour mixture
3. In a mixing bowl, beat egg whites until foamy. Add 1/2 cup sugar gradually, and continue beating only until meringue will hold up in soft peaks. Add red dye to approximate a watermelon color.
4. Cream butter or margarine. Gradually add remaining 1 cup sugar, and cream together until light and fluffy. Add sifted ingredients alternately with milk a small amount at a time, beating after each addition until smooth. Add red food dye until the same watermelon pinky/red is achieved. Mix in flavorings. Add colored meringue, and beat thoroughly into batter.  Pour into well greased and floured Egg Pan.
5. Bake at 350 degrees F (175 degrees C) for about 60 minutes. Check the springiness of the cake after about 45 min. Guess when it is done (when the depression caused by your finger is anti-depressed, or springs back up.) Leave the cake in pans until completely cool, then trim the bumpy puffed up cake above the rim of the Egg Pan and remove and transfer to a wire rack.

Basic Crusting Butter Cream

Ingredients:

• 1/2 cup solid high ratio shortening
• 1/2 cup butter softened
• 1 tablespoon of meringue powder
• 1 teaspoon Clear Vanilla Extract (or extract of choice)
• 4 cups sifted confectioners’ sugar (approx. 1 lb.)
• 2 tablespoons milk
• Green food color (add after cake is frosted with the white frosting)

In large bowl, cream shortening and butter with electric mixer. Add vanilla and milk. Gradually add sugar, one cup at a time, beating on a slow speed. Scrape sides and bottom of bowl often. Keep bowl or covered with a damp cloth until ready to use. Refrigerated in an airtight container, this icing can be stored 2 weeks. Don’t overwhip or it will bring air to the icing and is impossible to smooth. If you have a kitchen Aid use white attachment, not whip attachment.
