Substitutions & Key Variations
If you’re missing some ingredients or want to make substitutions, here are a few ideas:
- Flour: You can use cake flour for a lighter texture.
- Sugar: Coconut sugar or brown sugar can be used for a different flavor.
- Butter: If you’re out of butter, you can use vegetable oil (1 cup oil for 1 cup butter).

For key variations, you can add chocolate chips for a chocolate vanilla cake, or layer it with fruit such as strawberries or raspberries.
Step-by-step
Step 1: Prepare the Oven and Pans
Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans to prevent sticking.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, combine the all-purpose flour, granulated sugar, baking powder, and salt. Mix these dry ingredients thoroughly until well blended.
Step 3: Combine Wet Ingredients
Add the softened butter, eggs, vanilla extract, and buttermilk to the dry ingredients.
Step 4: Mix Until Smooth
Using an electric mixer on medium speed, beat the mixture until smooth and well combined. This should take about 2-3 minutes.
Step 5: Prepare for Baking
Divide the batter evenly between your two prepared cake pans.
Step 6: Bake the Cakes
Place the pans in the preheated oven and bake for 25-30 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean.
Step 7: Cool the Cakes
Once baked, let the cakes cool in the pans for 10 minutes. Then, transfer them to wire racks to cool completely.
Step 8: Frost and Enjoy!
Frost with your favorite vanilla frosting and serve. Enjoy the delightful taste of your homemade vanilla cake!
Success Tips
- Temperature: Make sure your butter is actually softened and not melted to achieve the right texture.
- Texture: Avoid overmixing once you add in the wet ingredients; this keeps the cake fluffy.
- Common Mistakes: Do not open the oven door while baking, as it can cause the cakes to collapse.
How to Serve
Serve slices of this delicious vanilla cake on its own or topped with your favorite frosting. It pairs well with a scoop of ice cream or a drizzle of chocolate sauce for dessert lovers.
Storage & Reheating
Store leftover cake in an airtight container at room temperature for up to 3 days. If you have excess frosting, it can also be stored separately. For longer storage, wrap the cake in plastic wrap and freeze for up to 2 months. To reheat, simply place a slice in the microwave for about 10-15 seconds.
