Ingredients

Scale
  • 2 ½ cups (320g) all-purpose flour, sifted
  • 2 tablespoons unsweetened cocoa powder (preferably Dutch-processed)
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 ¾ cups (350g) granulated sugar
  • 1 cup (240ml) vegetable oil (can substitute with light olive oil)
  • 1 cup (240ml) buttermilk, room temperature (or 1 cup milk + 1 tablespoon vinegar, let sit 5 minutes)
  • 3 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 tablespoon green food coloring (gel or liquid)
  • 1 teaspoon white vinegar
  • 8 ounces (225g) cream cheese, softened
  • ½ cup (115g) unsalted butter, softened
  • 3 to 4 cups (360-480g) powdered sugar, sifted
  • 1 to 2 tablespoons milk or heavy cream

Instructions

  1. Preheat oven to 350°F (175°C). Grease and flour a 9-inch shamrock-shaped cake pan or line with parchment paper.
  2. Sift together flour, cocoa powder, baking soda, and salt in a medium bowl.
  3. In a large bowl, beat sugar and vegetable oil until combined. Add eggs one at a time, beating well after each.
  4. Stir in buttermilk, vanilla extract, green food coloring, and white vinegar.
  5. Gradually add dry ingredients to wet ingredients, mixing on low speed until just combined. Avoid overmixing.
  6. Pour batter into prepared pan, smooth top, and tap gently to release air bubbles.
  7. Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean. Start checking at 30 minutes.
  8. Cool cake in pan for 15 minutes, then invert onto a wire rack to cool completely.
  9. Beat cream cheese and butter until light and fluffy (3-5 minutes). Gradually add powdered sugar, mixing well after each addition.
  10. Add milk or heavy cream to adjust frosting consistency.
  11. Once cake is cool, frost evenly with cream cheese frosting. Decorate with green sanding sugar or shamrock sprinkles if desired.
  12. Serve immediately or refrigerate covered for up to 3 days.

Notes

Use gel food coloring for a vibrant color without adding extra liquid. If frosting is too soft, chill for 20 minutes before spreading. Avoid overmixing batter to keep cake tender. If cake edges brown before center is done, tent with foil and bake longer.
