Classic Lemon Cake with Lemon Buttercream Frosting

The Lemon Cake That Tastes Like Actual Sunshine

There are chocolate cakes, there are vanilla cakes, and then there is lemon cake, the one that somehow feels both celebratory and effortless at the same time. This Classic Lemon Cake with Lemon Buttercream Frosting is the kind of dessert that gets requested year after year. Bright, buttery, and layered with real citrus flavor from both the zest and the juice, it is the cake people talk about long after the party is over.

Whether you are baking for a birthday, a spring brunch, a baby shower, or just a Tuesday that needs brightening up, this recipe delivers every single time.

Why This Recipe Works So Well

A lot of lemon cakes are timid with the citrus, offering only a whisper of lemon flavor that disappears the moment you take a bite. Not this one. Here is what makes it stand out:

• Double the lemon: Both zest and fresh juice go into the batter, and again into the frosting. You get lemon in every single layer.
• Sour cream for moisture: A touch of sour cream keeps the crumb incredibly tender without making the cake heavy.
• Fluffy, not overly sweet frosting: The lemon buttercream is creamy and bright, balancing the richness of the butter with a good hit of citrus.

Chef's Tip: Always zest your lemons before juicing them. Once the lemon is juiced, the skin collapses and zesting becomes nearly impossible.

The Tools and Ingredients That Make a Difference

For a cake this simple and flavorful, quality ingredients do a lot of heavy lifting. Using real butter, fresh lemons, and full-fat sour cream will give you noticeably better results than any substitutions. A reliable microplane zester and a good stand mixer also make this process smoother and more enjoyable.

A Few Tips Before You Start Baking

Lemon cake is forgiving, but a little preparation goes a long way:

Room temperature ingredients are non-negotiable. Cold butter will not cream properly, and cold eggs can cause the batter to curdle. Pull everything out of the fridge at least 30 to 45 minutes before you begin.

Do not overmix the batter. Once the flour goes in, mix only until the streaks of flour disappear. Overmixing develops gluten and leads to a dense, tough cake.

Let the layers cool completely before frosting. Rushing this step is the fastest way to end up with melted, sliding frosting. If you are short on time, pop the layers in the freezer for 20 minutes after they have cooled at room temperature.

Baker's Note: If your frosting feels too stiff, add heavy cream one teaspoon at a time until it loosens. If it feels too soft, refrigerate it for 10 to 15 minutes, then re-whip.

How to Get That Perfect Lemon Flavor

The secret is in the zest. Lemon zest contains the essential oils from the skin, which carry far more concentrated flavor than juice alone. When you rub zest into the sugar before beating it with the butter, those oils release and infuse the entire batter with a deep, fragrant citrus aroma that juice simply cannot replicate on its own.

Use unwaxed lemons when you can, and always wash them thoroughly before zesting. Organic lemons are a great choice here since you are using the skin.

1x2x3x

• 2 1/2 cups all-purpose flour, spooned and leveled
• 2 1/2 tsp baking powder
• 1/2 tsp baking soda
• 1/2 tsp salt
• 1 cup unsalted butter, softened to room temperature
• 1 3/4 cups granulated sugar
• 4 large eggs, room temperature
• 1 tsp pure vanilla extract
• 2 tbsp lemon zest, from about 3 large lemons
• 1/4 cup fresh lemon juice, freshly squeezed
• 3/4 cup whole milk, room temperature
• 1/4 cup sour cream, room temperature
• 1 cup unsalted butter, softened, for frosting
• 4 cups powdered sugar, sifted, for frosting
• 3 tbsp fresh lemon juice, for frosting
• 1 tbsp lemon zest, for frosting
• 2 tbsp heavy cream, for frosting, plus more as needed
• 1 pinch of salt, for frosting

Instruction

1

Preheat your oven to 350 degrees F (175 degrees C). Grease and flour two 9-inch round cake pans, then line the bottoms with parchment paper circles.

2

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.

3

In a large bowl using a hand mixer or stand mixer fitted with the paddle attachment, beat the softened butter and granulated sugar together on medium-high speed for about 3 to 4 minutes, until the mixture is pale, light, and fluffy.

4

Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract and lemon zest.

5

In a small bowl or measuring cup, combine the milk, sour cream, and fresh lemon juice. Stir briefly.

6

With the mixer on low, add the flour mixture to the butter mixture in three additions, alternating with the milk mixture, beginning and ending with the flour. Mix until just combined after each addition. Do not overmix.

7

Divide the batter evenly between the two prepared pans and smooth the tops with a spatula.

8

Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean and the tops are lightly golden.

9

Let the cakes cool in the pans for 15 minutes, then turn them out onto a wire rack and let them cool completely before frosting.

10

To make the lemon buttercream, beat the softened butter in a large bowl on medium speed until very creamy, about 2 minutes. Add the sifted powdered sugar one cup at a time, mixing on low between additions.

11

Add the lemon juice, lemon zest, heavy cream, and pinch of salt. Beat on medium-high speed for 3 minutes until the frosting is light, fluffy, and spreadable. Add an extra splash of cream if it seems too thick.

12

Place one cooled cake layer on a serving plate or cake stand. Spread a generous layer of frosting over the top. Place the second layer on top, then frost the top and sides of the cake.

13

Garnish with extra lemon zest, thin lemon slices, or a light dusting of powdered sugar if desired. Slice and serve.

Serving and Storing Your Lemon Cake

This cake is beautiful as a simple two-layer round, but you can also dress it up with thin lemon slices, a few sprigs of fresh thyme, or edible flowers for a truly stunning presentation.

Serve slices at room temperature for the best texture. The butter in the frosting firms up in the fridge, so if you are storing leftovers cold, give each slice a few minutes on the counter before eating.

Leftovers keep well covered at room temperature for 2 days, or refrigerated for up to 5 days. Individual slices also freeze beautifully wrapped in plastic, making it easy to enjoy a piece whenever the craving hits.
