Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Cake:

2½ cups (312g) all-purpose flour

2 tsp baking powder

½ tsp baking soda

¼ tsp salt

¾ cup (170g) unsalted butter, softened

1¾ cups (350g) granulated sugar

4 large eggs

1 tbsp vanilla extract

1 cup (240ml) whole milk

½ cup (120ml) thick cooked custard, cooled

For the Buttercream Frosting:

1 cup (226g) unsalted butter, room temperature

4 cups (480g) powdered sugar

2–3 tbsp milk or heavy cream

1 tsp vanilla extract

Pinch of salt

Directions

Preheat your oven to 175°C (350°F). Grease and line three 8-inch round cake pans with parchment paper to prevent sticking and ensure easy removal after baking.

In a medium mixing bowl, sift together the all-purpose flour, baking powder, baking soda, and salt. Sifting helps create a lighter cake texture and evenly distributes the leavening agents.

In a large bowl, beat the softened butter and granulated sugar using an electric mixer until the mixture becomes pale, light, and fluffy. This process usually takes about 3 to 5 minutes and creates air pockets that help the cake rise beautifully.

Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract until fully incorporated.

Gradually add the dry ingredients to the butter mixture in three additions, alternating with the milk. Begin and end with the dry ingredients. Mix gently after each addition until just combined. Avoid overmixing, as this can make the cake dense.

Fold the cooled custard into the batter using a spatula. Stir carefully to keep the batter light and airy.

Divide the batter evenly among the prepared cake pans. Smooth the tops with a spatula for even baking.

Bake for 22 to 25 minutes, or until a toothpick inserted into the center comes out clean. The tops should be lightly golden and spring back when touched.

Allow the cakes to cool in the pans for about 10 minutes before transferring them to wire racks to cool completely.

To prepare the frosting, beat the butter until creamy and smooth. Gradually add the powdered sugar, mixing on low speed to avoid spills. Add the vanilla extract and a pinch of salt.

Pour in the milk or cream one tablespoon at a time until the frosting reaches a smooth, spreadable consistency.

Once the cake layers are completely cool, place one layer on a serving plate and spread a layer of buttercream on top. Repeat with the remaining layers. Frost the top and sides of the cake evenly, then decorate as desired.

Variations

For a richer flavor, replace the vanilla custard with homemade pastry cream. You can also add fresh berries between the cake layers for a fruity twist.

Chocolate lovers can mix mini chocolate chips into the batter or drizzle melted chocolate over the finished cake.

For a lighter frosting option, use whipped cream frosting instead of buttercream. You may also flavor the buttercream with almond extract or citrus zest for a different taste profile.

To make the cake extra festive, decorate it with sprinkles, toasted coconut, or crushed nuts.

Storage/Reheating

Store the cake in an airtight container at room temperature for up to 2 days. If your kitchen is warm, refrigerate the cake to keep the frosting stable.

In the refrigerator, the cake will stay fresh for up to 5 days. Allow chilled slices to sit at room temperature for about 20 minutes before serving for the best texture and flavor.

You can also freeze unfrosted cake layers for up to 2 months. Wrap each layer tightly in plastic wrap and place them in a freezer-safe bag or container.

Avoid reheating the frosted cake in the microwave, as the buttercream may melt. Instead, let refrigerated slices naturally come to room temperature before enjoying.
