Ingredients You’ll Need

The beauty of this Lemon Bar Cake lies in its simple, thoughtfully chosen ingredients. Each plays a crucial role in bringing out the vibrant lemon flavor while ensuring the perfect texture, from the crisp crust to the creamy frosting on top.

• All-purpose flour (1 1/2 cups): Forms the sturdy, buttery base crust essential for the cake’s structure.
• Granulated sugar: Used in both crust and cake layers to perfectly balance tartness and sweetness.
• Unsalted butter: Adds richness and helps create that flaky crust and tender cake crumb.
• Vanilla extract: Enhances and rounds out the bright lemon flavors elegantly.
• Pinch of salt: Vital for intensifying the sweetness and balancing flavors in every layer.
• Cake flour: Provides a soft, delicate crumb to the lemon cake without weighing it down.
• Baking powder: Ensures the cake rises nicely to a fluffy texture.
• Eggs: Bind the cake ingredients and contribute to the rich, moist texture.
• Sour cream: Adds moisture and a slight tang that highlights the lemon zest and juice beautifully.
• Lemons: Both the zest and juice are the stars, delivering fresh, vibrant citrus flavor.
• Egg yolks (for lemon curd): Create that silky, thick lemon curd so perfect for layering.
• Powdered sugar (for frosting): Provides smooth sweetness that balances the tang of the cream cheese.
• Cream cheese and heavy cream: Combine for a luscious, dreamy frosting topping the cake.

How to Make Lemon Bar Cake

Step 1: Prepare and Bake the Crust

Start by preheating your oven to 350°F (175°C). The crust is the heart of this recipe—a simple mixture of all-purpose flour, sugar, butter, vanilla, and a pinch of salt. Cut the cold butter into the flour and sugar until the mixture resembles coarse crumbs, then press it firmly into your baking pan. This creates a firm but tender base that will hold all the layers beautifully. Bake this crust for 10 minutes to set it slightly and develop that irresistible golden color.

Step 2: Mix and Bake the Lemon Cake

While the crust bakes, prepare the lemon cake batter by combining cake flour, baking powder, salt, butter, sugar, eggs, vanilla extract, sour cream, lemon zest, and lemon juice in a bowl. The sour cream helps make the batter moist and tender, while the lemon zest and juice infuse it with vibrant citrus notes. Pour this batter gently over the hot, baking crust to help it meld together. Bake the combined layers for 30 minutes, allowing the cake to rise and attain a soft, fluffy texture.

Step 3: Make the Lemon Curd

While your cake cools down, it’s time to make that luscious, tangy lemon curd. Combine fresh lemon juice, lemon zest, sugar, and egg yolks in a bowl and cook gently over low heat, stirring constantly until the mixture thickens to a smooth, custardy consistency. Finally, stir in unsalted butter to add a rich, velvety finish. Let the curd cool completely to set before using it as a layer or topping for your cake. This lemon curd is where the bold, fresh flavors truly shine.

Step 4: Frost and Assemble

For the final flourish, prepare the cream cheese frosting by whipping softened cream cheese and butter until smooth, then gradually adding powdered sugar, vanilla extract, and just enough heavy cream to achieve a silky spreadable texture. Once the cake has cooled completely, frost it generously with this tangy-sweet frosting. You can finish the Lemon Bar Cake by spreading the chilled lemon curd atop or serving it on the side, and garnish with some fresh lemon slices for extra brightness and visual appeal.

How to Serve Lemon Bar Cake

Garnishes

Feel free to add a sprig of mint or edible flowers for a pop of color and a hint of earthiness that pairs beautifully with the bright lemon flavors.

Side Dishes

This Lemon Bar Cake pairs wonderfully with light accompaniments such as whipped cream or a scoop of vanilla ice cream to mellow out the tartness. For a refreshing touch, serve a bowl of mixed berries or a crisp green salad with a tangy vinaigrette alongside for a balanced summer dessert spread.

Make Ahead and Storage

Storing Leftovers

After enjoying your Lemon Bar Cake, wrap any leftovers tightly with plastic wrap or store them in an airtight container in the refrigerator. This will keep the cake moist and fresh for up to 4 days while maintaining the integrity of the lemon layers and frosting.

Freezing

You can freeze the Lemon Bar Cake if you want to save it for later. Wrap the cake carefully in plastic wrap and then in aluminum foil to prevent freezer burn. Frozen properly, it will keep well for up to 2 months. When ready to enjoy, thaw overnight in the refrigerator.

Reheating

Because this cake is best enjoyed chilled or at room temperature, reheating is not usually necessary. However, if you prefer, you can let slices sit at room temperature for 30 minutes before serving to bring out the flavors and soften the frosting. Avoid microwaving as it can cause the frosting to melt unevenly.

FAQs

Can I make the crust gluten-free?

Absolutely! Substitute the all-purpose flour with a gluten-free flour blend that measures cup-for-cup, and you should get a similar flaky texture. Just keep an eye on texture as some gluten-free flours absorb more liquid.

Is it possible to make the Lemon Bar Cake dairy-free?

Yes, you can replace butter with dairy-free margarine or coconut oil, and use dairy-free cream cheese for the frosting. Sour cream can be substituted with a plant-based yogurt or a coconut cream alternative to maintain moisture.

Can I prepare parts of the Lemon Bar Cake in advance?

Definitely! The lemon curd and cream cheese frosting can be made a day ahead and kept in the fridge. The crust can also be baked before assembling, making the final assembly quick and stress-free.

What’s the best pan size for this cake?

A 9×13-inch baking pan works perfectly, providing the ideal thickness for both crust and cake layers. You want enough surface area to get that glorious lemon flavor in every bite.

How can I make the lemon flavor more intense?

If you’re a lemon lover, increase the lemon zest by one extra lemon or add an additional tablespoon of lemon juice in the cake batter. Just be careful not to add too much liquid, as it can affect the cake’s texture.
