Delicately sweet, moist, and infused with the sunny zest of fresh lemons, Gâteau au Citron—or French Lemon Cake—is a timeless classic that embodies the lightness and elegance of French home baking. Whether served at teatime, brunch, or as a simple dessert, this lemon cake offers the perfect balance of tangy freshness and buttery richness.

Let’s explore this elegant treat, along with how you can make the perfect lemon cake from scratch.

What Is Gâteau au Citron?

Gâteau au Citron is a tender loaf or sponge cake flavored with lemon zest and sometimes lemon juice or syrup, resulting in a cake that is moist, aromatic, and subtly tangy. While simpler than a glazed American-style lemon pound cake, the French version is lighter in texture and less sweet, making it suitable for everyday indulgence.

In France, this cake is often enjoyed with a cup of tea or espresso, and can be found in boulangeries and patisseries, as well as made fresh in home kitchens.

Ingredients for a Classic Gâteau au Citron

This recipe yields a soft, buttery lemon loaf that’s easy to make and hard to resist.

Ingredients:

1 cup (125g) all-purpose flour

½ tsp baking powder

¼ tsp salt

½ cup (115g) unsalted butter, softened

¾ cup (150g) granulated sugar

2 large eggs

Zest of 2 lemons

2 tbsp fresh lemon juice

¼ cup (60ml) milk or plain yogurt (for tenderness)

Optional: 1 tsp vanilla extract

For the Lemon Syrup (Optional but Recommended):

¼ cup (60ml) fresh lemon juice

¼ cup (50g) sugar

For the Glaze (Optional):

½ cup (60g) powdered sugar

1–2 tbsp lemon juice

How to Make Gâteau au Citron

Step 1: Preheat and Prepare

Preheat oven to 350°F (175°C).

Grease and line a 9x5-inch loaf pan or an equivalent cake tin with parchment paper.

Step 2: Make the Batter

In a bowl, sift together flour, baking powder, and salt.

In another bowl, beat the butter and sugar until light and fluffy.

Add eggs one at a time, beating well after each addition.

Mix in the lemon zest, juice, and vanilla extract (if using).

Alternately add the dry ingredients and milk (or yogurt), beginning and ending with flour. Mix until just combined.

Step 3: Bake the Cake

Pour the batter into the prepared pan.

Bake for 40–50 minutes, or until a toothpick inserted in the center comes out clean.

Let the cake cool slightly in the pan.


Step 4: Soak with Lemon Syrup (Optional but Adds Moisture)

While the cake is still warm, mix lemon juice and sugar in a small saucepan and heat gently until sugar dissolves.

Poke small holes in the cake with a skewer and brush the syrup over the top.

Let it soak in fully, then remove cake from the pan to cool completely.


Step 5: Glaze the Cake (Optional)

Whisk together powdered sugar and lemon juice to form a thick but pourable glaze.

Drizzle over the cooled cake and let it set before slicing.

Flavor Variations

Lavender Lemon Cake: Add a teaspoon of culinary lavender to the batter for a floral twist.

Almond Lemon Cake: Substitute ¼ cup of flour with almond flour for a moist, nutty flavor.

Lemon & Poppyseed Cake: Add 1 tbsp of poppy seeds for a delightful crunch.

Lemon Thyme or Lemon Basil: Infuse with fresh herbs for a gourmet variation.

How to Serve Gâteau au Citron

Serve at room temperature, either plain or glazed.

Enjoy with black tea, Earl Grey, or espresso.

Add a dollop of crème fraîche or whipped cream and fresh berries for an elegant dessert.

It also pairs beautifully with a light French rosé or sparkling wine for brunch or special occasions.

Storage Tips

Keeps well at room temperature for 2–3 days in an airtight container.

Refrigerate for up to a week, or freeze slices individually wrapped for longer storage.
