Classic Lemon Cake

A classic lemon cake is a tender, moist butter cake with bright lemon flavor throughout, topped with a smooth lemon glaze. The secret is using both lemon zest and fresh juice, added at different points, so the flavor stays bright instead of baking away.

Ingredients for Classic Lemon Cake

All-purpose flour gives the cake structure and a tender crumb. Butter creamed with sugar creates a light, fluffy base, while granulated sugar sweetens and helps trap air. Eggs at room temperature bind everything and add richness. Lemon zest brings intense citrus flavor that won’t fade in the oven, and fresh lemon juice adds brightness and tang to both the batter and glaze. Baking powder lifts the cake, while salt balances the sweetness. Sour cream makes the crumb moist and tender. Powdered sugar sweetens the glaze and creates a smooth coating.

Why This Classic Lemon Cake Works

Creaming soft butter and sugar together traps air bubbles that expand in the oven, making the cake light and fluffy. Adding eggs one at a time lets each one fully blend in, so the batter stays smooth and thick instead of breaking apart. Room-temperature ingredients mix more evenly and create a finer, more tender crumb than cold ones.

The zest goes into the batter early so the oils stay in the cake, while fresh juice gets added just before baking, keeping that bright flavor intact. Sour cream replaces some of the milk in a traditional cake, adding moisture and a subtle tang that makes the lemon taste fresher. The glaze sets up quickly at room temperature, giving you a shiny finish that doesn’t crack or slide off.

Mistakes To Avoid

Overmixing the batter after you add the flour makes the cake tough and dense. Once you add the dry ingredients, stir just until the flour disappears, then stop. The batter will be thick and may look slightly lumpy, and that is fine.

Using cold eggs and butter makes them harder to blend evenly, so the batter breaks or looks curdled, and the finished cake turns out dense and dry. Set them on the counter for 30 minutes before you start, or warm the eggs in a bowl of warm water for 5 minutes.

Baking the cake on the wrong oven rack makes the top brown too fast or the inside stay raw. Use the middle rack so heat circulates evenly all around the pan. If the top browns too quickly, tent it loosely with foil for the last few minutes.

Cutting the cake while it is still warm makes the crumb tear and fall apart. Let it cool in the pan for 15 minutes so it sets and firms up, then turn it out onto a wire rack and cool completely before slicing or glazing.

Ingredients

• 2 1/4 cups (281 grams) all-purpose flour
• 2 teaspoons baking powder
• 1/2 teaspoon salt
• 1/2 cup (113 grams) unsalted butter, softened to room temperature
• 1 1/2 cups (299 grams) granulated sugar
• 3 large eggs, room temperature
• Zest of 2 lemons
• 1/3 cup fresh lemon juice
• 1/2 cup sour cream, room temperature
• 1 3/4 cups (210 grams) powdered sugar, for glaze
• 2 tablespoons fresh lemon juice, for glaze
• 2 tablespoons unsalted butter, melted, for glaze

Step-by-step Instructions

1. Heat the oven to 350°F (175°C). Grease a 9-inch round cake pan and line the bottom with parchment paper.
2. Whisk together the flour, baking powder, and salt in a small bowl and set aside.
3. In a large bowl, beat the softened butter and granulated sugar with an electric mixer on medium speed for 3 to 4 minutes, until light and fluffy and pale in color.
4. Add the eggs one at a time, beating well after each addition, about 1 minute total. Add the lemon zest and beat for 30 seconds, until the zest is evenly mixed in.
5. Add the flour mixture and sour cream in two additions, starting and ending with flour. Beat on low speed, stopping as soon as the flour disappears, about 30 seconds total.
6. Stir in the 1/3 cup lemon juice by hand with a rubber spatula until just combined, then pour the batter into the prepared pan and smooth the top.
7. Bake at 350°F (175°C) for 32 to 35 minutes, until a toothpick inserted in the center comes out with a few moist crumbs and the edges are light golden brown.
8. Let the cake cool in the pan for 15 minutes, then run a thin knife around the edge, turn it out onto a wire rack, and cool completely, about 1 hour.
9. For the glaze, whisk together the powdered sugar, 2 tablespoons lemon juice, and melted butter in a small bowl until smooth, then drizzle over the cooled cake.
10. Let the glaze set for 15 minutes before slicing and serving.
