Ingredients
- 1 ½ cups all-purpose flour
- 1 cup granulated sugar
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ¼ teaspoon salt
- 1 large egg
- ½ cup vegetable oil
- ½ cup whole buttermilk, well shaken
- ½ cup hot water
- 1 tablespoon vanilla extract
FOR THE VANILLA FROSTING (enough for the top of one 8-inch or 9-inch cake)
- ¾ cup (1 ½ sticks) salted butter, softened at room temperature
- 1 ½ tablespoons whole buttermilk or heavy cream
- 2 teaspoons vanilla extract
- 1 ½ cups powdered sugar
- Optional garnish: sprinkles
Instructions
- Preheat oven to 350°F. Grease an 8-inch or 9-inch square or round cake pan or line with parchment. Set aside.
- In a large mixing bowl, whisk together the flour, sugar, baking soda, baking powder, and salt. Make a well in the center and add the egg, oil, and buttermilk. Whisk to combine.
- Add the hot water and whisk again until smooth. Add the vanilla extract; whisk to combine. At this point you should have a very thin, smooth batter.
- Pour the batter into the prepared pan. Tap the pan gently on the counter a few times to release any big air bubbles. Bake for about 30-40 minutes, or until a toothpick inserted in the center of the cake comes out clean. Baking times will vary depending on your oven and on the pan that you use.
- Let the cake cool completely before frosting.
FOR THE FROSTING
- In a large bowl, beat the butter, buttermilk (or cream), and vanilla extract with an electric mixer on medium-high speed until smooth, about 1 minute. Reduce the speed to medium-low, and gradually add the powdered sugar. Beat until smooth, about 4 minutes. Increase the speed to medium-high and beat until the frosting is light and fluffy, about 4 more minutes.
- Spread the frosting on the cooled cake. Garnish with sprinkles, if desired.
Notes
- My preference is always whole buttermilk. That said, if it's an emergency and you just don't have any buttermilk on hand, you can make ½ cup of homemade buttermilk by using regular whole milk and either lemon juice or white vinegar. To do so, pour ½ cup of regular milk into a small bowl. Add either ½ tablespoon of freshly squeezed lemon juice or ½ tablespoon of white vinegar. Give it a stir, let it sit for about 5 minutes, and then use it in the recipe as directed.
- This recipe yields enough frosting for the top of an 8-inch or 9-inch cake. If you'd like to frost the sides of the cake as well, or if you want to bake a larger cake, you'll need to double the frosting ingredients.
