How to Make Lemon Poppy Seed Cake

There is nothing quite like the bright, sunny aroma of a freshly baked moist lemon poppy seed cake filling your kitchen. This recipe is my go to for spring brunches, baby showers, or any day that needs a little citrus cheer. The combination of tender crumb, pop of poppy seeds, and tangy cream cheese frosting is simply irresistible. I will walk you through every step so you can bake a bakery worthy cake at home with confidence.

Lemon Poppy Seed Cake

Let us start with the cake layers. For the lightest texture, I use a mix of all purpose flour and cornstarch, which mimics cake flour perfectly. If you have cake flour on hand, use 2 1/4 cups (270g) instead. Here is what you need:

this …

• 2 cups (240g) all purpose flour
• 1/4 cup (30g) cornstarch
• 2 1/2 teaspoons baking powder
• 1/2 teaspoon salt
• 3/4 cup (170g) unsalted butter, room temperature
• 1/4 cup (60g) vegetable oil
• 1 1/2 cups (300g) granulated sugar
• 3 tablespoons fresh lemon zest
• 4 large eggs, room temperature
• 1/3 cup (90g) milk
• 1/2 cup (115g) plain yogurt (or buttermilk)
• 1/4 cup (58g) fresh lemon juice
• 2 tablespoons poppy seeds

Preheat your oven to 350°F (175°C). Grease two 8 inch round cake pans and line the bottoms with parchment paper. Sift the flour, cornstarch, baking powder, and salt together in a bowl and set aside.

In a large mixing bowl, combine the butter, oil, sugar, and lemon zest. Cream them together on medium speed for 2 to 3 minutes until the mixture is light, fluffy, and pale. This step is crucial for a tender crumb, so do not rush it. Add the eggs one at a time, beating well after each addition. The batter should look smooth and creamy.

Next, add the milk, yogurt, and fresh lemon juice. Mix on low until combined. The batter may look slightly curdled at this point, but that is perfectly normal. Switch to a rubber spatula. Gradually add the dry ingredients, folding gently until just a few streaks of flour remain. Overmixing will make the cake dense, so stop as soon as the flour disappears.

Fold in the poppy seeds. For extra flavor, you can soak the poppy seeds in the milk or buttermilk for 30 minutes before adding them; this softens the seeds and enhances their nutty taste. Divide the batter evenly between the prepared pans. Bake for 33 to 38 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Let the cakes cool in the pans for 15 to 20 minutes, then turn them out onto a wire rack to cool completely.

For an extra moist cake, brush the warm cake layers with a simple syrup made from equal parts sugar and water, plus a squeeze of lemon juice. This is the secret to a bakery style moist lemon poppy seed cake that stays tender for days.

Cream Cheese Frosting

This cream cheese frosting is the perfect partner for the bright lemon cake. It is tangy, creamy, and not too sweet. Here is how to make it:

• 1 cup (225g) unsalted butter, room temperature
• 3 cups (375g) powdered sugar
• 1 1/2 cups (335g) cold cream cheese (block type, not spreadable)
• 1 1/2 teaspoons vanilla extract
• 1 teaspoon fresh lemon juice

In a large bowl, beat the butter on medium high speed until light and fluffy, about 2 minutes. Gradually add the powdered sugar, one cup at a time, mixing on low until incorporated. Scrape the bowl as needed. Add the cold cream cheese, vanilla, and lemon juice. Mix on medium speed just until smooth. Be careful not to overmix; overworking the frosting can make it runny. If the frosting looks lumpy, switch to the whisk attachment or mix on high speed for a few seconds. For a thicker consistency, add an extra cup of powdered sugar.

How to Decorate Lemon Poppy Seed Cake

Once your cake layers are completely cool, it is time to assemble. Level the tops with a serrated knife if they domed slightly. Place one layer on a cake stand or plate. Spread a generous amount of frosting over the top. Place the second layer on top, then apply a thin crumb coat over the entire cake. Refrigerate for 15 minutes to set the crumb coat.

After the crumb coat is firm, apply the remaining frosting. Use a cake scraper or offset spatula to smooth the sides and top. For a decorative touch, transfer the leftover frosting to a piping bag fitted with a 1M star tip and pipe swirls around the top edge. Sprinkle a few extra poppy seeds over the top for a beautiful finish. The result is a stunning layer cake that tastes as good as it looks.

How to Store Lemon Poppy Seed Cake

Because this cake has cream cheese frosting, it needs proper storage. You can leave the cake at room temperature for up to half a day, but for longer storage, refrigerate it. Place the cake in an airtight container or cover it with a cake carrier to prevent it from drying out. It will keep well in the refrigerator for up to 4 days.

Before serving, let the cake sit at room temperature for about 30 minutes. This brings back the soft, tender texture and allows the flavors to shine. If you want to freeze the cake, wrap unfrosted layers tightly in plastic wrap and foil. Freeze for up to 3 months. Thaw at room temperature before frosting and serving. Frosted cake can also be frozen, but the texture of the cream cheese frosting may change slightly.
