Can I make this cake in advance?

Yes, you can bake the cake layers up to one week in advance if they are wrapped tightly in plastic and stored in the freezer. Thaw them in the refrigerator before assembling to ensure they stay moist. The pastry cream can also be made a day ahead of time.

What is the best way to store leftovers?

Store any remaining slices in an airtight container in the refrigerator for up to three days. Because of the butter content in the frosting, it is best to let the cake sit at room temperature for thirty minutes before serving. This allows the crumb and the buttercream to soften to their ideal texture.

Can I use all-purpose flour instead of cake flour?

While all-purpose flour will work in a pinch, it will produce a heartier and slightly tougher crumb. If you must use it, replace two tablespoons of flour with two tablespoons of cornstarch for every cup used. This helps mimic the lower protein content found in traditional cake flour.

Why did my pastry cream turn out runny?

If the pastry cream is too thin, it likely did not reach a sufficient temperature to activate the cornstarch. You must wait until the mixture begins to bubble gently before removing it from the heat. Ensure you whisk constantly during this process to avoid scorching the bottom of the pan.

Is there a substitute for whole milk in this recipe?

Whole milk provides the fat necessary for a tender cake, so low-fat or skim milk may result in a drier texture. If you must use a dairy-free alternative, full-fat oat milk or almond milk are the best options. However, the flavor and richness will be slightly altered from the traditional version.

Why is my Swiss meringue frosting so soft?

Soft frosting usually occurs if the butter was too warm or the environment in the kitchen is particularly humid. Place the entire mixing bowl in the refrigerator for fifteen minutes to firm up the fats. Once chilled, return it to the mixer and whip again until it reaches the desired consistency.

Instructions

Prepare the pans. Preheat your oven to 350°F (177°C), butter your 8-inch round pans, and line them with parchment paper for easy release.
Combine dry ingredients. In a mixer, blend the cake flour, sugar, baking powder, and salt, then gradually incorporate the softened butter until the mixture resembles coarse cornmeal.
Whip egg whites. In a separate bowl, beat the large egg whites for about two minutes until they are frothy, light, and hold air bubbles.
Incorporate liquids. Stir vanilla bean seeds, vanilla extract, and almond extract into the milk, then alternate adding the egg whites and milk mixture to the batter while mixing on low.
Bake the layers. Divide the batter between pans and bake for 25 to 30 minutes, or until a skewer inserted in the center comes out clean.
Cool the cakes. Rest the cakes in their pans for ten minutes before transferring them to wire racks to cool completely to room temperature.
Craft pastry cream. Whisk egg yolks, sugar, salt, milk, and cornstarch in a saucepan over medium-low heat until thickened, then finish with vanilla bean paste and butter before chilling.
Prepare the meringue. Whisk egg whites, sugar, cream of tartar, and salt over simmering water until the mixture reaches 160°F (71°C).
Whip the frosting. Transfer the meringue to a mixer and whip until glossy and cool, then gradually beat in room-temperature butter until smooth and creamy.
Assemble the cake. Trim the cooled layers, fill with chilled pastry cream, apply a crumb coat, and frost the exterior with the Swiss meringue.

Notes

Ensure all ingredients are at room temperature to achieve a perfectly smooth emulsion in both the batter and the buttercream.
Use a digital scale for measuring flour to avoid packing, which keeps the cake crumb delicate rather than heavy or dense.
Create a sturdy border of buttercream around the edges of the cake layers to prevent the pastry cream filling from leaking out.
If your Swiss meringue frosting looks curdled while adding butter, continue whipping steadily; the fat will eventually emulsify into a silky texture.
