Buttermilk Cake with Buttercream Frosting
Ingredients:
For the Cake:
1 cup (2 sticks) unsalted butter, softened
2 cups granulated sugar
4 large eggs, room temperature
3 cups all-purpose flour
1 tablespoon baking powder
½ teaspoon baking soda
½ teaspoon salt
1¼ cups buttermilk, room temperature
1 tablespoon vanilla extract
Instructions:
Preheat oven to 350°F (175°C).
Grease and flour three 8-inch or 9-inch round cake pans. Line bottoms with parchment paper for easier release.
In a large bowl, cream butter and sugar together until light and fluffy (about 4–5 minutes).
Add eggs one at a time, beating well after each.
In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
Alternate adding the dry ingredients and buttermilk to the butter mixture, starting and ending with flour. Mix just until combined.
Stir in vanilla extract.
Divide batter evenly between the three pans and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
Let cakes cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
Classic Buttercream Frosting
Ingredients:
1 cup (2 sticks) unsalted butter, softened
4–5 cups powdered sugar, sifted
¼ cup heavy cream or milk (adjust for consistency)
1 tablespoon vanilla extract
Pinch of salt
Instructions:
In a large bowl, beat butter until creamy (about 2 minutes).
Gradually add powdered sugar, 1 cup at a time, beating well and scraping sides as needed.
Add vanilla, salt, and 2–3 tablespoons cream. Beat until light and fluffy (about 3–4 minutes).
Adjust thickness: add more cream to thin, or more sugar to thicken.
Assembly:
Level cake layers if needed for flat stacking.
Place one layer on a cake board or plate. Spread a generous amount of buttercream on top.
Repeat with second and third layers.
Apply a thin crumb coat and chill for 15–20 minutes.
Frost entire cake with remaining buttercream. Decorate as desired (swirls, sprinkles, piping, etc.).
