This elegant 50th birthday cake celebrates a lifetime of grace, strength, and sweetness. Made with tender vanilla sponge, fresh lemon zest, and a luscious buttercream frosting, it's the perfect centerpiece for honoring a special woman on her milestone birthday.
Preheat oven to 350°F (175°C). Grease two 9-inch round pans and line the bottoms with parchment paper.
In a large bowl, beat butter and sugar until light and fluffy (about 3–4 minutes).
Add eggs one at a time, mixing well after each. Stir in vanilla and lemon zest.
In a separate bowl, whisk together flour, baking powder, and salt. Alternate adding dry mixture and buttermilk to wet mixture, starting and ending with dry.
Pour into prepared pans and bake for 25–30 minutes, or until a toothpick comes out clean. Cool in pans for 10 minutes, then transfer to a wire rack.
For the frosting: Beat butter until creamy, then add powdered sugar gradually. Add vanilla and cream; beat until fluffy and smooth.
Frost cooled cakes, stacking with a generous layer in between. Decorate with gold dust, pearls, or flowers as desired.
Notes
This cake can also be made as cupcakes (bakes in 18–20 minutes) or as a three-layer cake by doubling the recipe.
