Lemon Curd Layer Cake Recipe: Zesty Citrus Dessert Guide

Lemon Curd Cake: Soft, tender layers of lemon cake filled with bright lemon curd and topped with a fluffy seven‑minute frosting. The balance of sweet and tart makes this a refreshing dessert for any occasion.

The meringue-like seven‑minute frosting gives lemon meringue pie vibes while the cake stays moist and delicate. The lemon curd adds a creamy, tangy center that pairs perfectly with the soft cake and light frosting.

Why this lemon curd cake works so well

• Bright lemon flavor: Fresh lemon zest and juice shine through a light vanilla base for a refreshing, citrus-forward cake.
• Elegant for events: It’s special-occasion worthy—great for birthdays, showers, or a spring gathering.
• Super tender crumb: A combination of butter, cream cheese, and neutral oil keeps the cake moist without a fussy method.
• Easy shortcut: You can use store-bought lemon curd to save time while keeping excellent flavor.
• Generous yield: The recipe makes about 12 large or 16 smaller slices, so it’s perfect for sharing.

• Granulated sugar
• Large eggs: room temperature
• Buttermilk: or a suitable substitute if you don’t have it
• Pure vanilla extract
• All-purpose flour
• Baking soda and baking powder
• Kosher salt

For the lemon curd filling:

• Lemon zest (from a large lemon)

• Granulated sugar
• Egg yolks (reserve whites for the frosting)
• Butter cut into small pieces

For the seven‑minute frosting:

• Granulated sugar
• Egg whites at room temperature
• Lemon juice
• Vanilla extract

How to make the cake

For the cake:

1. Preheat the oven to 325ºF. Grease and flour two 9×2″ round pans and line with parchment circles.
2. In a stand mixer with the paddle, beat butter, cream cheese, oil, sugar, and lemon zest on medium‑high until very light and fluffy, about 4 minutes, scraping the bowl as needed.
3. Add eggs and vanilla, then mix until combined.
4. Beat in buttermilk on low just until combined.
5. Whisk flour, baking soda, baking powder, and salt in a separate bowl. With mixer on low, add half the dry mixture, then the rest, mixing only until incorporated—do not overmix.
6. Divide batter evenly between pans (an ice cream scoop helps), smooth the tops, and bake until a tester comes out clean or the center reaches 190ºF, about 35–40 minutes.
7. Cool in pans 5 minutes, loosen edges with a knife, invert onto a rack, and cool completely.

To make the lemon curd:

1. Set 1″ of water to a strong simmer in a small saucepan. In a heatproof bowl set over the simmering water (bowl must not touch the water), whisk sugar, lemon juice, and zest.
2. Whisk in the egg yolks and cook, whisking constantly, until the mixture thickens to coat the back of a spoon (about 6–10 minutes).
3. Remove from heat, whisk in butter until smooth, strain if necessary, and refrigerate until cool.

To make the seven‑minute frosting:

1. Bring 1″ of water to a strong simmer. In a heatproof bowl set over (but not touching) the water, combine sugar, egg whites, and lemon juice.
2. With the bowl over the warm water and the burner on low, beat with a hand mixer until the mixture is glossy and holds soft‑medium peaks, about 7 minutes. Remove from heat and beat in vanilla. Cool to room temperature before using.

To assemble:

1. Place one cake layer on a serving plate. Pipe or spoon a ring of frosting around the edge to form a dam.
2. Spoon the chilled lemon curd into the center and smooth it out.
3. Top with the second layer, then spread the remaining frosting over the top and sides of the cake.

Make-ahead and storage

You can make the lemon curd ahead and refrigerate it until assembly. The frosting can be prepared a few hours before and cooled to room temperature. Cake layers can be baked a day ahead, wrapped tightly in plastic, and stored at room temperature; for longer storage, freeze the layers. Avoid refrigerating plain cake layers as they stale faster in the fridge.

Once assembled, store the cake in the refrigerator if it won’t be served within four hours—lemon curd is perishable. For best texture, let refrigerated slices sit at room temperature for about 30 minutes before serving. Leftover lemon curd keeps in the fridge for about one week or up to three months in the freezer.

Pro tips

• Use an ice cream scoop to divide batter evenly between pans so the layers bake uniformly.
• When making the frosting, whisk sugar and lemon juice before adding egg whites to prevent the whites from cooking too quickly.
• If sugar crystals cling to the mixing bowl sides while whipping the frosting, brush them down with a wet pastry brush to avoid a grainy texture.
• Don’t overbeat the seven‑minute frosting. Stop at soft‑medium peaks to keep it soft and glossy; overwhipping dries it out.
• If you like the lemon meringue look, gently toast the frosting with a culinary torch just before serving.

Instructions

To make the cake:

• Preheat oven to 325ºF. Grease and flour two 9×2″ pans and line with parchment circles.
• Beat butter, cream cheese, oil, sugar, and lemon zest until very light and fluffy, about 4 minutes.
• Beat in eggs and vanilla, then add buttermilk on low until just combined.
• Whisk dry ingredients together. With mixer on low, add half the dry mix, then the rest, mixing only until incorporated.
• Divide batter between pans and bake until a tester comes out clean, about 35–40 minutes. Cool completely.

To make lemon curd:

• Simmer 1″ of water in a saucepan. Over the simmering water, whisk sugar, lemon juice, and zest, then whisk in egg yolks.
• Whisk constantly until thickened to yogurt consistency, about 6–10 minutes. Remove from heat, whisk in butter, strain if needed, and chill.

To make frosting:

• Over simmering water, combine sugar, egg whites, and lemon juice in a heatproof bowl that does not touch the water.
• Beat on low over the warm water until glossy and holding soft‑medium peaks, about 7 minutes. Stir in vanilla and cool.

• Top with the second layer and frost the top and sides with the remaining frosting.

Notes

Seven‑minute frosting

• You can substitute 3/4 tsp cream of tartar for the lemon juice if needed.
• Beat for about 7 minutes to reach soft‑medium peaks; avoid overbeating or the frosting will dry and form a crust.
• This frosting yields roughly 5 1/2 cups—enough for a two‑layer 9″ cake.

Lemon curd

• The recipe yields about 1 1/2 cups of curd.
• Use a nonreactive metal bowl and keep the water at a gentle simmer so the bowl does not touch the water.
• Whisk constantly to prevent curdling; the curd will thicken further as it chills.
