Ingredients

Scale
  • 2 ½ cups all-purpose flour (315 g)
  • 2 tablespoons cocoa powder (15 g)
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 ¾ cups granulated sugar (350 g)
  • 1 cup vegetable oil (240 ml)
  • 1 cup buttermilk (240 ml) (or 1 cup milk + 1 tablespoon lemon juice, let sit 5 minutes)
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 to 2 teaspoons green gel food coloring
  • 8 oz cream cheese, softened (225 g)
  • ½ cup unsalted butter, softened (115 g)
  • 4 cups powdered sugar (480 g)
  • 1 teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. Preheat the oven to 350°F (175°C). Grease two 9-inch round cake pans with butter and lightly dust with flour.
  2. In a large bowl, sift together the flour, cocoa powder, baking soda, and salt.
  3. In another bowl, whisk together the sugar, vegetable oil, buttermilk, eggs, vanilla extract, and green gel food coloring until smooth.
  4. Gradually fold the dry ingredients into the wet mixture using a rubber spatula until just combined. Do not overmix.
  5. Divide the batter evenly between the prepared pans and smooth the tops.
  6. Bake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean.
  7. Let the cakes cool in the pans for 10 minutes, then invert onto cooling racks and cool completely.
  8. To make the frosting, beat the cream cheese and butter until fluffy. Gradually add powdered sugar, vanilla extract, and salt, mixing until smooth and spreadable. Add a teaspoon of milk if too thick.
  9. Place one cake layer on a serving plate and spread a thick layer of frosting on top. Add the second layer and cover the entire cake with remaining frosting.
  10. Optionally chill the assembled cake for 30 minutes before serving to set the frosting.

Notes

Use gel food coloring for vivid color without thinning the batter. Keep cream cheese and butter at room temperature for smooth frosting. Avoid overmixing the batter to keep the cake tender. Test for doneness early to prevent dryness. Chill frosting if too soft before spreading. Cake flavors improve after resting overnight.
