Simple Birthday Cake is soft, moist, and perfect for any celebration. Whether you decorate it with sprinkles, fruit, flowers, or keep it minimalist, this reliable recipe is a crowd-pleaser for all ages and occasions.
Grease two 9-inch round cake pans and line the bottoms with parchment paper.
Whisk together flour, baking powder, and salt in a medium bowl.
Beat butter and sugar until light and fluffy.
Add eggs one at a time, mixing well after each. Stir in vanilla extract.
Alternate adding flour mixture and milk, mixing until just combined.
Divide batter between pans and bake at 350°F (175°C) for 25–30 minutes, until a toothpick comes out clean.
Cool cakes completely on a wire rack before frosting.
Notes
Swap vanilla with almond extract for a nutty twist, or use buttermilk for extra tenderness. For a chocolate version, replace part of the flour with cocoa powder. Decorate simply or lavishly—the cake adapts to your celebration style.
