Ingredients
- 2 ½ cups (310g) all-purpose flour
- 2 ½ teaspoons baking powder
- ½ teaspoon salt
- 1 cup (226g) unsalted butter, softened
- 1 ¾ cups (350g) granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup (240ml) whole milk
For the Buttercream Frosting
- 1 cup (226g) unsalted butter, softened
- 4 cups (480g) powdered sugar, sifted
- 2-3 tablespoons (30-45ml) whole milk or heavy cream
- 2 teaspoons vanilla extract
- A pinch of salt
Instructions
- Preheat your oven to 350°F (175°C). Grease two 8-inch round cake pans and line the bottoms with parchment paper for easy removal.
- In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- In a large mixing bowl, beat the softened butter and sugar together on medium speed until light and fluffy, about 3-4 minutes. Use a hand or stand mixer for best results.
- Add eggs one at a time, beating well after each addition. Incorporate the vanilla extract.
- Reduce mixer speed to low and alternately add the dry ingredients and milk, starting and ending with the dry ingredients. Mix until just combined; do not overmix.
- Divide the batter evenly between the prepared pans and smooth the tops with a spatula.
- Bake for 25-30 minutes, or until a toothpick inserted into the center of each cake comes out clean. Rotate pans halfway through baking for even results.
- Allow the cakes to cool in the pans for 10 minutes, then turn out onto wire racks to cool completely before frosting.
- While cakes are cooling, prepare the buttercream frosting. In a large bowl, beat softened butter until creamy, about 2 minutes.
- Gradually add sifted powdered sugar, beating on low speed to prevent dust clouds. Once combined, increase speed to medium and beat until fluffy.
- Add vanilla, salt, and 2 tablespoons of milk or cream. Beat on medium-high until smooth and spreadable. If too stiff, add more milk a teaspoon at a time.
- Place one cake layer on a serving plate. Spread a layer of buttercream evenly on top. Place the second cake layer over and apply a thin crumb coat around the entire cake. Chill for 30 minutes.
- Apply a final, thicker layer of buttercream around the cake, smoothing with an offset spatula or bench scraper. Decorate as desired.
Tips
- Substitutions: You can substitute buttermilk for milk for a tangier flavor and softer crumb. For a dairy-free version, use coconut oil and plant-based milk.
- Storage: Keep the cake covered in an airtight container at room temperature for up to 2 days or refrigerate for up to 4 days. Bring to room temperature before serving for best texture.
- Common Mistakes: Overmixing the batter can make the cake dense. Be gentle when combining ingredients once the dry and wet are added. Also, ensure cakes are fully cooled before frosting to prevent melting.
- Frosting consistency: If the buttercream is too soft, refrigerate for 15-20 minutes before applying. If too stiff, add a splash of milk or cream.
Serving Suggestions
Serve your birthday cake at room temperature, ideally within 2 hours of frosting. Decorate with sprinkles, fresh fruit, or themed cake toppers to suit the celebration. Pair with a glass of milk, tea, or coffee for a complete festive experience.
Variations
For a different flavor profile, consider adding lemon zest or orange extract to the cake batter. You can also incorporate chopped nuts, chocolate chips, or fruit into the batter for added texture. To customize the frosting, try mixing in food coloring, or flavored extracts like almond or peppermint for seasonal twists.
Storage and Reheating
Unfrosted cake layers can be stored tightly wrapped in plastic wrap at room temperature for up to 2 days or frozen for up to 1 month. To freeze, wrap each layer individually in plastic wrap and then in foil. Thaw at room temperature for about 2 hours before decorating. Once assembled and frosted, the cake is best enjoyed within 3 days. Keep refrigerated if not served immediately, and allow to come to room temperature before serving for optimal flavor and texture.
Frequently Asked Questions
Can I make this cake ahead of time?
Yes, you can prepare the cake layers up to two days in advance. Store them wrapped tightly in plastic wrap at room temperature or freeze for longer storage. Frost the cake on the day of serving for the freshest taste and appearance.
How do I prevent the cake from crumbling when frosting?
Ensure the cakes are completely cooled before frosting to prevent cracking. Applying a thin crumb coat and chilling the cake for 30 minutes helps set the layers and makes frosting easier. Use a stable, butter-based frosting like buttercream for better adhesion and smoothness.
What if my buttercream is too soft or runny?
If the buttercream is too soft, refrigerate it for 15-20 minutes before applying. Adding a little more sifted powdered sugar can also help thicken it. Conversely, if it’s too stiff, mix in a small splash of milk or cream until it reaches the desired consistency.
Can I use a different type of frosting?
Absolutely. While buttercream is classic and versatile, you can substitute it with cream cheese frosting, whipped cream, or fondant for different textures and flavors. Keep in mind that some alternatives may require adjustments in preparation and storage.
How do I decorate a birthday cake with buttercream?
Use piping bags and tips to create decorative borders, rosettes, or other designs. Fresh flowers, sprinkles, or themed cake toppers can add a festive touch. For a smooth finish, use an offset spatula or bench scraper to evenly spread the frosting and achieve a polished look.
Is this recipe suitable for gluten-free or vegan diets?
This particular recipe uses traditional ingredients like wheat flour and dairy. To adapt for gluten-free diets, substitute with a gluten-free flour blend. For vegan versions, replace butter with plant-based margarine or coconut oil, and use plant-based milk and egg replacers like flaxseed or applesauce.
