Why You’ll Love Lemon Curd Poppyseed Cake Recipe

I love this cake because it has a light and tender crumb while still feeling rich and satisfying. The lemon curd filling adds an intense citrus flavor that pairs beautifully with the delicate vanilla cake and crunchy poppy seeds.

Another reason I enjoy making this recipe is how impressive it looks once assembled, even though the process is surprisingly simple. The fluffy cake layers, creamy filling, and silky frosting create a bakery-style dessert that feels perfect for celebrations or afternoon coffee.

I also appreciate that the lemon flavor tastes natural and fresh rather than overly sweet, making every bite feel bright and refreshing.

Ingredients

(Note: All ingredient amounts are listed in the recipe card below.)

For the cake:

3 tablespoons very soft butter

⅓ cup oil, sunflower, canola, vegetable or any other mild tasting oil

1 cup sugar

1 teaspoon vanilla extract

1 ⅓ cup all-purpose flour

1 ½ teaspoons baking powder

1 ½ tablespoons poppy seeds

½ teaspoon salt

½ cup milk

3 large egg whites, (save the yolks for the lemon curd!)

For the filling:

¾-1 cup Ridiculously Easy Lemon Curd

For the lemon curd icing:

8 ounces very soft butter

¼ cup Ridiculously Easy Lemon Curd

1 teaspoon vanilla extract

⅛ teaspoon almond extract, optional

3 ½- 3 ¾ cups powdered sugar

3-4 tablespoons half and half or heavy cream

Directions

1. PREHEAT THE OVEN: I preheat the oven to 350˚F. I spray one 8-inch round cake pan with baking spray and line the bottom with parchment paper.
2. PREPARE THE CAKE BATTER: In a medium-large bowl, I stir the soft butter until creamy. I add the oil, sugar, and vanilla extract and mix until smooth and creamy.
3. ADD THE DRY INGREDIENTS: I sprinkle in the baking powder, salt, and about one-third of the flour. I stir gently until the flour disappears.
4. ADD THE MILK AND FLOUR IN STAGES: I add half the milk and stir, then another portion of flour. I repeat with the remaining milk and flour, mixing gently after each addition. Finally, I stir in the poppy seeds.
5. WHIP THE EGG WHITES: In a separate clean bowl, I whisk the egg whites until foamy and soft peaks form.
6. FOLD THE EGG WHITES INTO THE BATTER: Using a spatula, I gently fold the whipped egg whites into the batter while being careful not to overmix.
7. BAKE THE CAKE: I transfer the batter to the prepared pan and smooth the top. I bake for 35–40 minutes until a toothpick inserted into the center comes out clean.
8. COOL THE CAKE: I let the cake cool in the pan for 15 minutes before turning it out onto a wire rack to cool completely.
9. SLICE AND FILL: Using a long serrated knife, I carefully slice the cake horizontally into two layers. I place the bottom layer onto a serving plate and spread the lemon curd filling across the center, leaving about a ½-inch border around the edges.
10. ADD THE TOP LAYER: I gently place the second cake layer on top with the cut side facing down.
11. PREPARE THE LEMON CURD ICING: In a bowl, I combine the soft butter, lemon curd, vanilla extract, and almond extract if using. I mix until creamy, then gradually add the powdered sugar and half and half until the frosting becomes smooth and spreadable.
12. FROST THE CAKE: I frost the cake as desired with the lemon curd icing before serving.

Variations

I sometimes add fresh blueberries between the cake layers along with the lemon curd for a fruity twist that pairs beautifully with the citrus flavor.

For extra lemon intensity, I occasionally mix fresh lemon zest directly into the cake batter and frosting.

When I want a lighter finish, I decorate the cake with whipped cream and fresh berries instead of fully frosting the outside.

I also enjoy using almond extract in the icing because it adds a subtle bakery-style flavor that complements the lemon wonderfully.

Storage/Reheating

I store the cake covered in the refrigerator for up to 4 days because the lemon curd filling stays freshest when chilled.

Before serving, I usually let the cake sit at room temperature for about 20–30 minutes so the frosting softens slightly and the flavors become more pronounced.

I do not recommend reheating this cake, since it is best served cool or at room temperature.

For longer storage, I freeze individual slices tightly wrapped for up to 2 months and thaw them overnight in the refrigerator.
