Method
- Preheat oven to 350°F (175°C). Grease and line three 8-inch cake pans with parchment paper.
- In a medium bowl, whisk together the flour, sugar, baking soda, salt, and cocoa powder until well combined.
- In a large bowl, whisk together the oil, buttermilk, eggs, vanilla extract, vinegar, and butter extract (if using) until completely smooth and emulsified.
- Add the chosen gel food coloring to the wet ingredients and whisk vigorously until the color is uniform and intensely green.
- Add the dry ingredients to the wet ingredients in three batches, whisking just until each addition is incorporated and no dry pockets remain. Do not overmix.
- Divide the batter evenly among the prepared cake pans.
- Bake for 25-28 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
- Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely.
- To make the frosting: In a stand mixer with the paddle attachment, beat the chilled cream cheese and softened butter on medium speed until completely smooth and lump-free.
- With the mixer on low, gradually add the sifted powdered sugar, one cup at a time, until fully incorporated.
- Add the vanilla extract and salt. Beat on medium-high speed for 2-3 minutes until the frosting is light and fluffy.
- If needed, level the cooled cake layers with a serrated knife.
- Place one cake layer on a cake stand. Spread a layer of frosting evenly over the top. Repeat with the second and third layers.
- Apply a thin layer of frosting over the entire cake to create a crumb coat. Chill the cake for 20 minutes.
- Apply the final, thick layer of frosting to the top and sides of the cake. Decorate as desired.
Notes
For the most vibrant green, use a combination of blue and yellow gel colors instead of pre-mixed green. Ensure all ingredients (buttermilk, eggs) are at room temperature for a smooth batter. Do not reduce the acidic ingredients (buttermilk, vinegar) as they are crucial for texture and color. Chilling the cake after the crumb coat ensures a clean final frosting layer. Store the finished cake, covered, in the refrigerator for up to 5 days. Bring to room temperature for about 30 minutes before serving for the best flavor and texture.
