How to Make Lemon Curd Cake With Lemon Buttercream Frosting Recipe

Step 1: Prepare the Lemon Curd

Start by beating the vegan butter, granulated sugar, fine salt, and lemon zest together until smooth and fragrant. Incorporate the eggs and yolks one by one, mixing thoroughly after each addition to build a rich, velvety base. Stir in the fresh lemon juice, which may cause the mixture to look a little curdled at first—don’t worry, this is expected. Transfer the mixture to a small pot and gently heat it over medium-low, stirring constantly until it thickens to about 175°F (80°C) and coats the back of a spoon. Pour the curd into a bowl, cover it directly with plastic wrap to prevent skin forming, then chill in the fridge until it’s time to assemble your cake.

Step 2: Bake the Lemon Cake Layers

Preheat your oven to 340°F (170°C) and prepare two 6-inch cake pans with grease and parchment paper. Whisk together the flour, cornstarch, salt, baking soda, baking powder, sugar, and lemon zest to evenly distribute the leavening agents and zest. Cut the softened butter into this dry mix until it resembles sandy crumbs, which ensures a tender crumb. In a separate bowl, mix eggs, mayo, and vanilla for moisture and a bit of tang. Combine wet and dry ingredients gently, then stir in the non-dairy milk until smooth, taking care not to overmix. Divide batter evenly into pans and bake for 20-25 minutes, checking doneness with a toothpick. Cool briefly before transferring to a wire rack.

Step 3: Whip up the Lemon Buttercream Frosting

Using a stand mixer, beat vegan butter and shortening until light and fluffy. Gradually add powdered sugar in thirds, scraping down the bowl to ensure even mixing each time—you want your frosting smooth and not grainy. Once fully incorporated, mix in salt, vanilla, lemon juice, and optional zest to brighten the flavor. This frosting is luscious, rich, and packed with lemon goodness, perfect for both spreading and piping.

Step 4: Assemble the Cake

Place one cake layer on a stand or plate and apply a thin frosting layer using an offset spatula. Pipe a buttercream border to create a well in the middle, then spoon in a generous dollop of tangy lemon curd. Repeat with the second layer. Once all layers are stacked, apply a crumb coat all over the cake to lock in moisture and crumbs. Refrigerate for 30 minutes to set the crumb coat. Finish by decorating the cake as fancy or simple as you like—with more buttercream, lemon curd, or fresh lemon slices for that extra wow factor.

Garnishes

Side Dishes

This cake pairs wonderfully with light accompaniments like a simple mixed berry salad, a scoop of vanilla bean ice cream, or even a cup of hot herbal tea to balance the tangy sweetness. Each pairing highlights the cake’s lemon flavor without overwhelming the palate.

Creative Ways to Present

For a layered celebration, slice the cake into elegant wedges and plate with drizzled lemon glaze or extra lemon curd on the side. You can also make mini versions in cupcake tins using the same frosting and lemon curd method for parties. For an extra special touch, pipe decorative lemon blossoms or rosettes with the buttercream using vibrant yellow and white piping tips.

Make Ahead and Storage

Storing Leftovers

Leftover slices of this Lemon Curd Cake With Lemon Buttercream Frosting Recipe should be stored in an airtight container in the refrigerator. The cool environment keeps the buttercream stable and the cake fresh for up to 4 days while preserving its moist texture and vibrant flavor.

Freezing

You can freeze the fully assembled cake wrapped tightly in plastic wrap and then foil for up to 2 months. Thaw overnight in the fridge before serving. Alternatively, freeze individual layers or just the lemon curd and frosting separately to freshen the experience when you bake the cake.

Reheating

Since this is a delicate frosted cake, avoid reheating it to preserve the buttercream texture. If you prefer your cake slightly warmer, bring it to room temperature for 30 minutes before enjoying. The lemon flavors will still shine beautifully without needing heat.

FAQs

Can I make this cake gluten-free?

Absolutely! Substitute the all-purpose flour for a gluten-free blend with xanthan gum to help with structure. Be sure to measure carefully, as gluten-free flours behave differently, but the lemon flavor and moist texture will remain delightful.

Is this recipe vegan?

The original Lemon Curd Cake With Lemon Buttercream Frosting Recipe contains eggs and dairy butter, but you can easily adapt it by using vegan egg replacers and plant-based butters to keep the cake moist and flavorful without animal products.

How tangy is the lemon flavor?

This cake strikes a beautiful balance between sweet and tart. The lemon curd packs a zesty punch, the cake layers have mellow lemon zest, and the frosting adds a creamy, citrusy finish that is bright without being overwhelming.

Can I use regular butter instead of vegan butter?

Yes, regular unsalted butter can be used in place of vegan butter for those who do not require dairy-free ingredients. It will add a rich flavor and maintain the texture exactly as intended.

What’s the best way to transport this cake?

For safe transport, keep the cake chilled and secured in a cake box. If taking it on a longer journey, add a layer of parchment between cake layers and pack some ice packs nearby to keep the frosting firm and stable.
