  • 2 large eggs
  • 1 teaspoon lemon juice
  • 1/2 teaspoon vanilla extract
  • 2 1/4 teaspoons baking powder
  • 2 3/4 cups sifted cake flour
  • 1/2 cup milk

Instructions

  1. Ensure all ingredients are at room temperature before starting.
  2. Preheat the oven to 350°F (175°C). Grease and flour your cake pans.
  3. In a mixing bowl, beat the softened butter and granulated sugar until light and fluffy.
  4. Add the eggs one at a time, beating well after each addition.
  5. Mix in the lemon juice and vanilla extract.
  6. In a separate bowl, whisk together the baking powder and sifted cake flour.
  7. Gradually add the dry ingredients to the wet mixture, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined.
  8. Divide the batter evenly into separate bowls (depending on how many colors you want), and add food coloring to each as desired.
  9. Pour each colored batter into the prepared cake pans, creating layers or stripes as preferred.
  10. Bake in the preheated oven for about 30 minutes, or until a toothpick inserted into the center comes out clean.
  11. Allow the cakes to cool in the pans for 10 minutes, then turn out onto wire racks to cool completely.
  12. Once cooled, assemble and frost as desired.

Tips & Substitutions

For a lighter cake, ensure the butter is well creamed with the sugar, as this incorporates air. You can substitute milk with buttermilk for added moisture and tang. If you have a gluten sensitivity, consider using a gluten-free cake flour blend. Adding a pinch of salt enhances flavor, even in sweet recipes like this one.

Serving Suggestions

This colorful cake is perfect for celebrations and pairs beautifully with a scoop of Vanilla Ice Cream or a dollop of whipped cream. Serve it alongside a refreshing fruit salad or a light dessert like Boot Hill Salad for a delightful contrast. Garnish with fresh berries for an extra pop of color.

Storage & Reheating

Store leftover cake in an airtight container at room temperature for up to three days. For longer storage, wrap slices in plastic wrap and freeze for up to a month. To reheat, simply microwave a slice for about 15-20 seconds or let it come to room temperature before serving.
