Description

Notes: 

This is a small cake. I bake the cake in two small cake pans:  6×2-inch round cake pans. You could also use one 9-inch cake pan. Or if you want to make a larger cake, you can double the recipe and use two 9-inch pans. See the notes below the recipe for the larger yield. That said, I can’t say enough good things about investing in those two small cake pans. This recipe makes the perfect size cake with very few leftovers. 

To make cupcakes: Be sure only to fill the cupcake holes halfway up with batter—they will overflow/not bake properly.

There are two frosting recipes below. I used to use the more traditional cream cheese-butter frosting, but I now prefer the whipped cream-cream cheese frosting recipe, which I adapted from this Stella Park’s recipe. I use Stella’s proportions but use a different method.  

Which recipe to use? If you like more of a whipped cream frosting, Stella’s recipe is great bc it’s kind of a cross between a whipped cream frosting and a cream cheese frosting.


Ingredients

for the cake:

  • 1 1/2 cups (192 g) all-purpose flour
  • ¼ teaspoon salt
  • ½ teaspoon baking soda
  • 1 1/2 teaspoons baking powder
  • ½ cup (115 g) neutral oil, such as grapeseed or avocado
  • 1 cup (215 g) sugar
  • 2 eggs, lightly beaten
  • ½ cup + 2 tablespoons (158 g) buttermilk
  • 2 teaspoons vanilla extract

for the whipped cream – cream cheese frosting (this is my preference):

  • 8 oz  (226 g) cream cheese
  • 1/2 cup (100 g) sugar
  • 2/3 cup (140 g) heavy cream
  • pinch sea salt
  • 1 teaspoon vanilla

for the cream cheese – butter frosting:

  • 2 sticks (16 tablespoons | 8 oz) unsalted butter, room temperature
  • 8 oz. cream cheese, room temperature
  • ½ teaspoon vanilla extract
  • confectioners’ sugar to taste (about ¾ cup)
  • flaky sea salt to taste

for presenting:


Instructions

  1. Preheat the oven to 350ºF. Whisk together the flour, salt, baking soda, baking powder, and sugar. Add the oil, eggs, buttermilk, and vanilla, and stir to combine.
  2. Coat two 6-inch cake pans (or one 9-inch pan) with nonstick spray (or butter liberally). I like to cut a round of parchment paper and fit it into the bottom of each pan. Pour half of the batter into each pan and bake for 25 to 30 minutes or until an inserted toothpick comes out clean. Cool in pan for 15 minutes before inverting onto a cooling rack. Cool completely.
  3. To make the whipped cream – cream cheese frosting: Beat cream cheese and sugar together until light and fluffy. Add the heavy cream, a pinch of salt, and the vanilla. Beat again until light and fluffy. 
  4. To make the cream cheese -butter frosting: Beat cream cheese and butter together until light and fluffy. Add vanilla. Add confectioners’ sugar to taste. Add a pinch of salt. Mix again. Taste. Adjust taste as desired.
  5. To assemble: cut each cake in half crosswise, layer as follows: cake, frosting, cake, frosting, until all four layers are stacked. Frost the entire outside of the cake with the remaining frosting. Shower sprinkles over top.

Notes

for a large cake (two 9-inch pans):

  • 3 cups all-purpose flour
  • 1/2 teaspoon salt
  • 1 teaspoon baking soda
  • 1 tablespoon baking powder
  • 2 cups sugar
  • 1 cup vegetable oil
  • 4 eggs, whisked lightly
  • 1¼ cups buttermilk
  • 1 tablespoon vanilla
  1. Follow the instructions above, but bake in two buttered 9-inch pans for roughly 35-40 minutes.
