6. Bake

- 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 wire racks to cool completely.
7. Make the Frosting
- Beat butter on medium speed until creamy.
- Add powdered sugar, 1 cup at a time, beating slowly until combined.
- Stir in vanilla and salt.
- Add cream a tablespoon at a time until desired consistency is reached (smooth and spreadable).
8. Frost and Decorate
- Level cake layers if necessary.

Frequently Asked Questions About Homemade Birthday Cake
1. Can I make the cake layers in advance?
Yes, absolutely. You can bake the cake layers up to 2 days in advance. Once cooled, wrap them tightly in plastic wrap and store them at room temperature or in the refrigerator. For longer storage, freeze them for up to 2 months—just thaw overnight before frosting.
2. How do I keep the cake moist?
To ensure a moist and tender cake, use room temperature ingredients, don’t overmix the batter, and avoid overbaking. You can also brush each cake layer with a simple sugar syrup before frosting to lock in extra moisture, especially if you’re baking ahead.
3. Can I use this recipe for cupcakes or other pan sizes?
Yes. This batter makes approximately 24 standard cupcakes—just reduce the baking time to 18–22 minutes. You can also use 8-inch pans (for thicker layers) or a 9×13-inch pan for a sheet cake. Always test doneness with a toothpick.
4. Can I color or flavor the batter and frosting?
Absolutely. This recipe is a blank canvas. Add gel food coloring to the batter or frosting for a themed cake, or try flavor variations like almond extract, lemon zest, or strawberry puree for a fruity twist. Just be sure to adjust liquids slightly when adding purees.
