Ingredients

For the Cake:

• 1 1/4 cups all-purpose flour
• 1 1/2 tsp baking powder
• 1 cup granulated sugar
• 1/4 tsp salt
• 3/4 cup vegetable oil
• 3 tbsp unsalted butter, melted
• 1/2 cup buttermilk
• 2 large eggs (room temperature)
• 1 tsp vanilla extract

For the Buttercream Frosting:

• Pinch of salt

• 1 cup unsalted butter (room temperature)

• 2 ½ cups powdered sugar

• 2 teaspoons vanilla extract

• 2 tablespoons heavy whipping cream

Instructions

1. Preheat & Prepare

Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan with butter and line it with parchment paper for easy removal.

2. Mix the Dry Ingredients

In a large mixing bowl, whisk together the flour, baking powder, sugar, and salt.

3. Add the Wet Ingredients

Pour in the vegetable oil, melted butter, and buttermilk. Mix until just combined. Then, add the eggs and vanilla extract, mixing until smooth. Avoid overmixing to keep the cake light and fluffy.

4. Bake

Pour the batter into the prepared cake pan and smooth the top. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.

5. Cool the Cake

Let the cake cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

6. Prepare the Buttercream Frosting:

In a stand mixer or large bowl, beat the butter on medium speed for 2 minutes until light and fluffy.

Add vanilla extract and continue mixing.

Gradually add powdered sugar, ½ cup at a time, mixing on low speed to avoid a sugar cloud.

Pour in heavy cream and a pinch of salt, then increase speed to medium-high and beat for 4-5 minutes until smooth and fluffy.

7. Assemble & Garnish

Place the cooled cake on a serving plate. Spread the whipped cream frosting evenly over the top. Garnish with frozen berries for a beautiful and tasty finish.

8. Enjoy!

Slice and serve immediately or refrigerate for up to 2 days for a refreshing chilled dessert.

Tips for the Best Single Layer Vanilla Cake Recipe

• Use room-temperature eggs – This ensures a smooth batter and even baking.
• Don’t skip the buttermilk – It adds moisture and enhances the cake’s flavor.
• Chill the mixing bowl for the whipped cream – This helps achieve a stable and fluffy texture.
• Fresh vs. frozen berries – Both work great, but frozen berries add a slight chill and extra juiciness to the topping.

Frequently Asked Questions

What size cake pan should I use?

This recipe is designed for an 8-inch round cake pan. If using a 9-inch pan, the cake will be a little thinner and may bake a few minutes faster.

Can I make this vanilla cake ahead of time?

Yes! You can bake the cake up to 2 days in advance. Once it has cooled completely, wrap it tightly and store it at room temperature until you’re ready to frost and serve.

Can I freeze this single-layer vanilla cake?

Yes. Let the cake cool completely, then wrap it tightly in plastic wrap and aluminum foil or place it in a freezer-safe container. Freeze for up to 3 months and thaw at room temperature before decorating.

Can I make this recipe into cupcakes?

Yes! This batter makes about 12 standard cupcakes. Start checking for doneness around 18–20 minutes, or when a toothpick inserted into the center comes out clean.

Why did my vanilla cake turn out dry?

The most common causes are overbaking or adding too much flour. Measure your flour carefully and begin checking the cake a few minutes before the recommended baking time.

Can I use a different frosting?

Absolutely! While vanilla buttercream pairs perfectly with this cake, you can also use chocolate buttercream, cream cheese frosting, whipped frosting, or your favorite homemade frosting.

Can I add sprinkles or mix-ins to the batter?

Yes! Fold in up to ½ cup of rainbow sprinkles, mini chocolate chips, or chopped nuts just before pouring the batter into the cake pan.

How should I store leftover vanilla cake?

Store leftover cake in an airtight container at room temperature for up to 3 days. If your frosting contains dairy, it’s best to refrigerate the cake and bring it to room temperature before serving.
