How to Make Lemon Cake
Bake the Cake

Prepare the cake batter according to the recipe. Divide the batter evenly between three greased 8-inch round pans lined with parchment. Bake until the cakes spring back when touched or a toothpick comes out clean. Cool completely before assembling.
Tip: You can bake this in two 9-inch pans for thicker layers; they will need additional baking time. Alternatively, slice thicker 9-inch layers in half for a four-layer cake.
Make the Lemon Curd
Cook the curd over low heat, whisking constantly until it thickens into a sauce-like consistency. Remove from heat, stir in cold butter until smooth, then press plastic wrap onto the surface and chill to prevent a skin from forming.
Prepare the Lemon Frosting
Beat room-temperature butter until light and fluffy, then add powdered sugar gradually and finish with lemon juice and a pinch of salt. Chill briefly if needed, and reserve about 1 cup for piping a border during assembly.
Assemble the Cake

- Place the first cake layer top-side down on a cake board or plate. Spread 1 cup of frosting evenly to the edges.
- Pipe a 1/2-inch frosting border around the edge to create a dam.
- Spoon about 3/4 cup lemon curd into the center and spread it to the frosting dam.
- Top with the second layer and repeat the frosting dam and curd step.
- Place the final layer on top, crumb coat the cake with a thin layer of frosting, and chill for one hour.
- Finish with the remaining frosting, smooth the sides and top, and garnish with thin lemon slices.

Expert Tips
- Use room-temperature ingredients for a smoother batter and creamier frosting.
- Constantly stir lemon curd while cooking to prevent curdling.
- Do not overmix the cake batter — overmixing creates dense cakes.
- Level baked layers for even stacking and a professional finish.
- Chill the crumb-coated cake for at least an hour to make final frosting easier and cleaner.
Storage and Freezing
Refrigerate the finished cake in an airtight container for 3–5 days. For longer storage, freeze wrapped slices or the whole cake for 1–2 months. Thaw overnight in the refrigerator or enjoy straight from the freezer.

Common Questions
Can I make this as a sheet pan cake?
Yes. Bake in a sheet pan, slice the cake horizontally, spread lemon curd between layers, then frost and slice to serve.
Can I use boxed cake mix?
A boxed vanilla or lemon cake mix can be used as a shortcut. Adjust additions like lemon juice and zest to boost fresh flavor.
Can I use store-bought lemon curd?
Yes — store-bought curd is a convenient shortcut, though homemade curd will be fresher and more vibrant.
