This Lemon Layer Cake is tall, tender, and packed with bright citrus flavor in every forkful. Soft cake layers brushed with lemon syrup, filled with tangy homemade lemon curd, and covered in smooth lemon cream cheese frosting. I made this for my sister Karla's birthday last spring, and she took one bite and said, "This tastes like sunshine had a baby with a cloud." The whole table went quiet after that, just forks scraping plates.
What I love most is how the lemon curd adds that little zing between the layers without being too sweet. It's easier than it looks, too. You'll need a stand mixer and a little patience, but the result is bakery-quality and absolutely worth it.

See Recipe Card Below This Post For Ingredient Quantities
Lemon Curd:
- Egg Yolks: These thicken the curd and give it that silky, rich texture.

- Salted Butter: Adds creaminess and a smooth finish once the curd is cooked.
Lemon Cake:
- Cake Flour: Creates a soft, tender crumb that melts in your mouth.

How to Make Lemon Layer Cake
Follow these steps to build your beautiful lemon layer cake from scratch.
Prepare the Lemon Curd: Fill a small saucepan with about 2 inches of water and bring it to a gentle boil over low heat, then reduce to a simmer. In a medium heat-safe bowl, whisk together the egg yolks, sugar, and lemon juice. Set the bowl on top of the saucepan and whisk constantly for 10 to 15 minutes, until the mixture thickens and looks like pudding, reaching about 170 to 180°F. Remove from heat, stir in the butter until melted and smooth, then cover and refrigerate until fully set.
Prepare the Lemon Cake: Preheat your oven to 325°F. Grease and flour three 8-inch cake pans. In a large bowl, whisk together the cake flour, milk powder, baking powder, baking soda, and salt, then set aside.
Cream the Lemon Zest and Sugar: In the bowl of a stand mixer, add the lemon zest and sugar. Pinch and rub the zest into the sugar with your fingers for 2 to 3 minutes until it smells bright and fragrant. Add the butter and vegetable oil, then mix on medium speed for 4 minutes until light and fluffy.
Add the Eggs: In a small bowl, whisk together the eggs, egg whites, lemon emulsion, butter vanilla emulsion, and almond extract. Add this mixture to the stand mixer in three portions, making sure each addition is fully blended before adding the next.
Combine Wet and Dry Ingredients: Add half of the dry ingredients to the mixer and mix for about 15 seconds. Then add the buttermilk, lemon juice, and sour cream, mixing until just combined. Scrape down the sides of the bowl, then add the remaining dry ingredients and mix until a thick, smooth batter forms.
Bake the Cakes: Divide the batter evenly among the three prepared pans. Bake for 40 to 45 minutes, until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Prepare Lemon Simple Syrup: In a small saucepan, combine the water and sugar over medium heat. Stir until the sugar fully dissolves, about 5 to 7 minutes. Remove from heat, stir in the lemon juice, and set aside to cool.
Prepare Lemon Cream Cheese Frosting: Clean your stand mixer bowl and add the butter and powdered sugar. Beat on low for 1 to 2 minutes, then increase to medium-high and beat for 3 minutes until light and fluffy. Add the lemon juice and lemon emulsion, mixing until smooth. Add the cold cream cheese and mix for 2 to 4 minutes until completely smooth and creamy.
Assemble the Cake: Slice each cooled cake layer in half horizontally so you have six thin layers. Place the first layer on a cake stand and brush it lightly with lemon simple syrup. Spread about one-third of the lemon curd on top. Add the second layer, brush with syrup, and spread a thin layer of frosting. Repeat with the remaining layers, alternating between curd and frosting.
Chill and Frost: If you'd like, wrap the assembled cake with a cake collar to help keep the sides neat. Refrigerate for 1 hour. Apply a thin crumb coat of frosting all over the cake, then chill for another 30 minutes. Finish with a final, thick layer of frosting, smoothing it with an offset spatula.
Serve and Store: Slice and serve at room temperature for the best flavor and texture. Store any leftovers in an airtight container in the fridge for up to 5 days. Let the cake sit out for about 1 hour before serving if it's been chilled.
Substitutions and Variations
If you need to swap ingredients or want to try a twist, here are a few ideas that work well.
- Cake Flour: You can use all-purpose flour if that's what you have. For every cup of all-purpose, remove 2 tablespoons and replace with 2 tablespoons of cornstarch, then sift it together. It won't be quite as tender, but it'll still be delicious.
- Lemon Emulsion: If you can't find emulsion, use lemon extract instead. Start with half the amount and taste as you go since extract can be stronger.
- Buttermilk: Make your own by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk. Let it sit for 5 minutes until it curdles slightly, then use it as called for.
- Sour Cream: Greek yogurt works as a substitute and adds the same moisture and tang.
- Cream Cheese Frosting: If you want a lighter option, you can use whipped cream or a simple buttercream instead. The tang from the cream cheese is lovely, though.
- Lemon Curd: Store-bought lemon curd works in a pinch if you're short on time. Just make sure it's thick enough to spread between the layers without sliding.
Equipment For Lemon Layer Cake
Having the right tools makes assembling this Lemon Layer Cake so much easier.
A stand mixer is your best friend here for creaming the butter and sugar and mixing the thick batter. You can use a hand mixer, but it'll take a little longer and your arm might get tired.
You'll need three 8-inch round cake pans. If you only have two, you can bake in batches, just keep the extra batter at room temperature while the first two bake.
A small saucepan is essential for making the lemon curd using the double boiler method. You'll also need a heat-safe bowl that fits snugly on top.
An offset spatula makes frosting the layers and smoothing the sides much easier, though a regular butter knife works too. A pastry brush is handy for applying the lemon simple syrup evenly to each layer.
If you want super clean layers, a bread knife or Lemon Layer Cake leveler helps you slice each cake in half horizontally. And a cake collar (optional) keeps the sides neat while you chill and frost.
Storage and Make-Ahead Tips
This Lemon Layer Cake keeps beautifully, which makes it perfect for parties or when you want dessert ready ahead of time.
Store the fully assembled and frosted Lemon Layer Cake in an airtight container in the fridge for up to 5 days. The lemon curd and cream cheese frosting both need to stay cold, so don't leave it out on the counter for more than an hour or two.
You can make the lemon curd up to 3 days in advance. Just keep it covered tightly in the fridge until you're ready to assemble.
The cake layers can be baked a day ahead. Let them cool completely, wrap each one tightly in plastic wrap, and store at room temperature. You can even freeze the layers for up to 2 months. Thaw them in the fridge overnight before assembling.
The lemon simple syrup and frosting can both be made a day early and stored in the fridge. Just let the frosting come to room temperature and give it a quick stir before using.
If you want to freeze the whole assembled Lemon Layer Cake, wrap it tightly and freeze for up to 1 month. Thaw it in the fridge overnight, then let it sit at room temperature for an hour before serving.
Serving Suggestions
This lemon layer cake is stunning on its own, but here are a few ways to make it even more special.
Serve it with a handful of fresh berries on the side. Raspberries, blueberries, or strawberries add a pop of color and a little extra tartness that plays nicely with the lemon.
A dollop of whipped cream on each slice adds a light, airy contrast to the rich frosting. You can even fold a little lemon zest into the whipped cream for extra flavor.
Pair it with a cup of hot tea or iced lemonade for a perfect afternoon treat. The bright citrus flavors make it feel refreshing, even though it's a rich dessert.
If you're serving this for a celebration, garnish the top with candied lemon slices or a sprinkle of lemon zest for a bakery-style finish.
Expert Tips
Bring all your ingredients to room temperature before you start. Cold eggs and butter don't mix as smoothly, and you'll end up with a dense batter. I usually set everything out on the counter about an hour before I start baking.
Don't skip the lemon simple syrup. It might seem like an extra step, but it keeps the Lemon Layer Cake layers moist and adds an extra layer of lemon flavor. Brush it on while the cakes are still slightly warm for the best absorption.
Chill the cake between frosting steps. That first crumb coat might look messy, but once you chill it and add the final layer of frosting, everything smooths out beautifully.
Use cold cream cheese for the frosting. It sounds backwards, but cold cream cheese blends more smoothly and helps the frosting stay firm and pipeable. If it's too soft, the frosting can get runny.
Slice the cake layers carefully. Use a long serrated knife and work slowly, rotating the Lemon Layer Cake as you go. If the layers aren't perfectly even, don't stress. The frosting hides a lot.
Let the cake sit out before serving. The flavors really come alive when the Lemon Layer Cake isn't ice cold. About an hour at room temperature is perfect.
FAQ
Can you make lemon cake with lemon curd?
Absolutely! Lemon curd makes a fantastic filling for layer cakes. It adds a tangy, creamy contrast to the soft cake layers and pairs beautifully with lemon frosting. Just make sure your curd is thick enough so it doesn't slide out between the layers. My trick is to chill it completely before assembling.
Can you mix lemon curd into cake batter?
You can, but I wouldn't recommend it for this recipe. Lemon curd is best used as a filling or swirled on top. Mixing it into the batter can make the texture too dense and the curd might break down during baking. If you want lemon flavor in the batter itself, stick with lemon zest, juice, and emulsion.
What can I bake with a jar of lemon curd?
So many things! You can use it to fill cupcakes, layer it in a trifle, swirl it into cheesecake batter, spread it on scones or muffins, or fold it into whipped cream for a simple mousse. It's also amazing spread on toast or stirred into yogurt. My sister Karla eats it straight from the jar, but I don't officially recommend that.
Can you put lemon curd in a sponge?
Yes! Sponge cakes are light and airy, so lemon curd makes a great filling. Just make sure the sponge layers are completely cooled before spreading the curd, and brush them with a little simple syrup first to keep everything moist. The tangy curd cuts through the sweetness of the sponge really nicely.

Ingredients
Method
- Start by making the lemon curd. Fill a small saucepan with about 2 inches of water. Heat over low heat, bringing it to a simmer.
- In a medium heat-safe bowl, combine the egg yolks, sugar, and lemon juice. Place the bowl over the saucepan, whisking constantly to avoid cooking the eggs. Continue whisking for 10-15 minutes until the mixture thickens and reaches 170-180°F.
- Once thickened, remove the bowl from the heat. Stir in the butter until fully melted. Cover with plastic wrap and refrigerate until set.
- Preheat the oven to 325°F. Grease and flour three 8-inch cake pans.
- In a large bowl, whisk together the dry ingredients: cake flour, milk powder, baking powder, baking soda, and kosher salt. Set aside.
- In the bowl of a stand mixer, combine lemon zest and sugar. Rub the zest into the sugar for 2-3 minutes to release its oils and aroma.
- Add the butter and vegetable oil to the sugar mixture. Using the paddle attachment, mix on medium speed for 4 minutes until light and fluffy.
- In a small bowl, whisk together eggs, egg whites, lemon emulsion, butter vanilla emulsion, and almond extract. Slowly add the egg mixture to the stand mixer, about ⅓ at a time, ensuring each addition is fully incorporated before adding more.
- Add half of the dry ingredients to the wet ingredients and mix until just combined. Then add buttermilk, lemon juice, and sour cream, mixing until fully incorporated.
- Add the remaining dry ingredients and mix until a thick batter forms.
- Divide the batter evenly between the three prepared pans and bake for 40-45 minutes. Test with a skewer-when it comes out with a few moist crumbs, the cakes are done.
- Cool the cakes in the pans for 10 minutes before transferring them to a wire rack to cool completely.
- While the cakes are baking, prepare the lemon simple syrup. Combine water and sugar in a small saucepan. Heat over medium heat for 5-7 minutes, stirring occasionally, until the sugar dissolves. Remove from heat and stir in the lemon juice.
- To make the frosting, beat butter and powdered sugar together in a stand mixer on low speed for 1-2 minutes. Once combined, increase the speed to medium-high and mix for 3 minutes. Add lemon juice and lemon emulsion, mixing for an additional 20 seconds.
- Add the cold cream cheese to the frosting and mix for 2-4 minutes until smooth and fully combined.
- To assemble the cake, slice each cake in half horizontally. Brush the cut sides of each cake layer with lemon simple syrup. Spread a layer of lemon curd on the bottom layer.
- Place the second cake layer on top and brush with more syrup. Spread a thin layer of frosting. Repeat with the remaining layers.
- Once assembled, wrap the cake with a cake collar (optional) and refrigerate for 1 hour. After the first chill, apply a thin layer of frosting, then refrigerate for another 30 minutes before applying the final layer of frosting.
- Store the cake in an airtight container in the refrigerator for up to 5 days. Before serving, allow it to sit at room temperature for about 1 hour for best texture.
