Prep & Cook Time

• Prep Time: 15 minutes
• Cook Time: 30 minutes
• Total Time: 45 minutes
• Servings: 4

Ingredients

• baking spray
• 1 large egg (room temperature)
• 2 tsp pure vanilla powder (use half this amount if you prefer less rich vanilla flavor)
• ½ cup granulated sugar
• 3 tbsp vegetable oil
• ⅓ cup buttermilk (room temperature)
• ¾ cup cake flour
• 3/4 tsp baking powder
• 1/4 tsp salt
• 1/8 tsp baking soda
• 1/2 cup salted butter (softened (1 stick))
• 2 cups powdered sugar
• 2 tbsp heavy cream
• 2 tsp pure vanilla powder (use half this amount if you prefer less rich vanilla flavor)
• salt (to taste)

Instructions

1. Preheat your oven to 350°F (175°C). Generously coat a 6-inch round cake pan with baking spray.
2. In a medium bowl, whisk together the 1 large egg, 2 tsp pure vanilla powder (use half this amount if you prefer less rich vanilla flavor), ½ cup granulated sugar, and 3 tbsp vegetable oil until smooth and slightly thickened.
3. Whisk in the ⅓ cup buttermilk until fully combined.
4. In a separate bowl, sift together the ¾ cup cake flour, 3/4 tsp baking powder, 1/4 tsp salt, and 1/8 tsp baking soda.
5. Pour the batter into the prepared pan and bake for 28-32 minutes, or until a toothpick inserted into the center comes out clean.
6. Let the cake cool in the pan for 10 minutes, then turn it out onto a wire rack to cool completely.
7. For the frosting, beat the 1/2 cup salted butter with an electric mixer until creamy. Gradually add the 2 cups powdered sugar, mixing on low speed until combined.
8. Increase the mixer speed to medium-high and beat for 2 minutes. Add the 2 tbsp heavy cream and 2 tsp pure vanilla powder (use half this amount if you prefer less rich vanilla flavor) and beat for another 1-2 minutes until light and fluffy. Taste and add salt if desired.
9. Once the cake is completely cool, frost it generously with the vanilla buttercream. Slice and serve.

Variations

• Glaze it: For a lighter finish, thin the frosting with a little extra cream to make a pourable glaze and drizzle it over the cake.
• Add texture: Create a “naked cake” look by applying a very thin layer of frosting, letting the cake layers peek through.
• Individual Cakes: Bake the batter in a muffin tin lined with parchment liners to make 4-5 individual mini cakes or cupcakes.
• Berries & Cream: Slice the cake in half horizontally, fill the middle with sweetened whipped cream and fresh berries, and dust the top with powdered sugar instead of frosting.

Tips for Success

• Ensure your egg and buttermilk are truly at room temperature for a smooth, evenly combined batter that rises well.
• Use a kitchen scale to measure your cake flour for the most accurate results; fluff the flour, spoon it into the cup, and level it off if measuring by volume.
• Don’t overmix the batter after adding the dry ingredients; a few small lumps are fine. Overmixing develops gluten and leads to a tough cake.
• Let the cake cool completely before frosting, otherwise the buttercream will melt and slide right off.

Storage & Reheating

Store the frosted cake, covered at room temperature, for up to 2 days, or in the refrigerator for up to 5 days. For the best texture, let chilled cake slices sit at room temperature for 20-30 minutes before serving. This cake is best enjoyed fresh and is not suitable for reheating.

FAQ

Can I use all-purpose flour instead of cake flour?

Yes, but the texture will be slightly denser. For a closer substitute, replace 1 ½ tablespoons of the measured all-purpose flour with cornstarch for every ¾ cup.

What can I use if I don’t have buttermilk?

Make your own: add 1 teaspoon of white vinegar or lemon juice to ⅓ cup of regular milk. Let it sit for 5-10 minutes until it curdles slightly before using.

Can I use unsalted butter for the frosting?

Yes, you can use unsalted butter. You will likely want to add a small pinch of the “salt (to taste)” to balance the sweetness.

Why is my cake dense or gummy?

This is usually caused by overmixing the batter or using cold ingredients. Mix just until combined and ensure your wet ingredients are at room temp.

Can I double this recipe?

Absolutely. You can double all ingredients to make two 6-inch layers or one 8-inch or 9-inch round cake. The baking time may need to be increased by 5-10 minutes.

My frosting is too thick/thin. How can I fix it?

If it’s too thick, add more heavy cream, 1 teaspoon at a time. If it’s too thin, add more powdered sugar, a few tablespoons at a time, until it reaches your desired consistency.
