Method
 

Sun Cake Layers
  1. Preheat the oven to 350°F (175°C) and prep two 8-inch round pans.
  2. In a bowl, whisk together the flour, baking powder, and salt.
  3. In another bowl, cream the butter, sugar, and lemon zest until fluffy.
  4. Add the eggs one at a time, mixing well after each addition, and then add vanilla.
  5. Alternate adding the dry ingredients and milk, mixing until just combined.
  6. If desired, add yellow food coloring to the batter.
  7. Bake in the preheated oven for 25 to 30 minutes until a toothpick comes out clean. Cool completely.
Moon Cake Layers
  1. Use the same clean pans and keep the oven at the same temperature.
  2. In a bowl, mix together the flour, cocoa powder, sugar, baking soda, baking powder, and salt.
  3. In another bowl, whisk together the wet ingredients: eggs, milk, oil, and vanilla.
  4. Combine the wet and dry mixtures, adding hot coffee to loosen the batter. Don't worry if the batter is loose.
  5. Bake for 30 to 35 minutes until a toothpick inserted comes out clean. Cool completely.
Assembly Time
  1. Cut each round layer in half vertically to get half suns and half moons.
  2. Pair the halves: place a sun half on one side and a moon half on the other, spreading a layer of buttercream between.
  3. To create a checkerboard pattern when you cut into the cake, alternate sides for each layer.
  4. Apply a crumb coat with white frosting and chill the cake for 30 minutes.
Decorating
  1. Divide the buttercream into two batches.
  2. Color one batch with yellow and orange for the Sun side.
  3. Color the other batch deep blue or black for the Moon side.
  4. Frost each side and blend the orange into the yellow for added effect.
  5. Add star sprinkles to the dark side and pipe a little crescent moon if desired.
  6. Smooth the dividing line carefully for visual impact.
  7. Decorate with gold leaf, piped borders, or other creative ideas.
  8. Chill the cake until set. Then serve and enjoy!
