Instructions

Buttermilk Layer Cake Recipe

Preheat and Prepare

Preheat your oven to 350°F. Grease and flour two 9-inch round cake pans. This ensures your cakes will release easily after baking.

Mix Dry Ingredients

In a bowl, whisk together 2 1/2 cups flour, 1 tbsp baking powder, and 1/2 tsp salt. This step aerates the flour, leading to a lighter cake.

Cream Butter and Sugar

Using an electric mixer, beat 1 cup butter and 2 cups sugar until light and fluffy, about 5 minutes. This incorporates air, making your cake fluffy.

Add Eggs and Vanilla

Beat in 4 eggs, one at a time, then stir in 1 tsp vanilla. Adding eggs gradually ensures a smooth batter.

Alternate Dry Ingredients and Buttermilk

Add the dry ingredients in three parts, alternating with 1 cup buttermilk, starting and ending with the dry ingredients. This method prevents the batter from curdling.

Bake the Cakes

Divide the batter between the prepared pans. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Cool in pans for 10 minutes, then transfer to a wire rack.

Tips and Tricks

For an extra moist cake, brush the layers with simple syrup before frosting. If you’re short on buttermilk, make a substitute by adding 1 tbsp vinegar to 1 cup milk. Always use a serrated knife to level your cake layers for a professional look. To ensure even baking, rotate your pans halfway through the baking time. For a richer flavor, toast your flour before using it in the recipe.

Recipe Variations

  • Chocolate Buttermilk Cake: Add 3/4 cup cocoa powder to the dry ingredients.
  • Lemon Buttermilk Cake: Add the zest of 2 lemons to the batter and use lemon juice in the frosting.
  • Spiced Buttermilk Cake: Mix in 1 tsp cinnamon, 1/2 tsp nutmeg, and 1/4 tsp cloves with the dry ingredients.
  • Berry Buttermilk Cake: Fold 1 cup fresh berries into the batter before baking.
  • Coconut Buttermilk Cake: Substitute 1/2 cup buttermilk with coconut milk and sprinkle shredded coconut between layers.

Frequently Asked Questions

Can I make this cake ahead of time? Absolutely! This cake stays moist for up to 3 days when stored properly. Just wrap it tightly in plastic wrap or keep it in an airtight container.

What can I use instead of buttermilk? If you’re in a pinch, you can make a quick substitute by adding 1 tablespoon of vinegar or lemon juice to 1 cup of milk and letting it sit for 5 minutes.

How do I prevent my cake from doming? To avoid a domed top, try lowering your oven temperature by 25°F and baking for a slightly longer time. Also, ensure your baking powder is fresh.
