Lemon Poppy Seed Cake with Raspberry Curd – light and fluffy lemon poppy seed cake with a homemade raspberry curd layer and a lemon buttercream.
Are you guys tired of hearing about my birthday?
I’m so tired of talking about it. I told you in my ice cream post that I really don’t like my birthday and the only reason that I let my husband invite friends over for burgers this past weekend was because I didn’t realize it was my birthday until it was too late.
I used my birthday/friends coming over as an excuse to make this cake that I’ve wanted to make for so long. You guys know that I am very much against fruit in desserts but the cake just spoke to me for some reason. I think it’s because I love the lemon & raspberry combination.
This cake turned out so beautiful. I love the little black specks throughout. The lemon zest was tart and the crumb light and fluffy. The curd was smooth and a nice change from typical layer cake filling.
How To Make Lemon Poppy Seed Cake
- Whisk together flour, baking powder, salt, and poppy seed to remove lumps
- In a separate bowl, use an electric mixer to beat egg whites and cream of tartar to stiff peaks
- Using another bowl, beat butter, sugar, and lemon zest
- Alternately add milk and flour mixture to the butter mixture; beat until just combined
- Use a rubber spatula to fold the beaten egg whites into the batter
- Divide batter into 2 9-inch round cake pans buttered and lined with parchment paper
- Bake for 25 – 30 minutes, until the cakes are golden and cooked through
- Cool completely before filling and frosting
How To Make Raspberry Curd
- Melt butter in a large saucepan
- Add fresh raspberries, egg yolks, sugar, and salt
- Cook mixture, mashing the berries as it cooks
- Stir constantly until the mixture has thickened to a curd like consistency, about 10 minutes
- Pour curd though a mesh strainer to remove seeds
- Stir in lemon juice
- Cover and refrigerate until ready to fill cake
How To Make Lemon Buttercream Frosting
- Use an electric mixer to beat butter and lemon zest until light and fluffy
- Add powdered sugar and beat until smooth
- Add lemon juice and beat for 1 minute longer
- Store in an airtight refrigerator until ready to frost cake
How Long Is Lemon Poppy Seed Good For?
This cake will be fine for up to a week if covered and stored in the refrigerator. Try to store it in an airtight container so it doesn’t dry out.
I would bring it to room temperature (or at least take the chill off) by setting it on the counter for a while before serving it.

For the raspberry curd:
- 8 tbsp. unsalted butter
- 1 pint ripe raspberries or 1 12-oz. package frozen raspberries, thawed
- 5 large egg yolks, lightly beaten
- ¾ cup sugar
- Pinch of salt
- 2-3 tsp. fresh lemon juice
For the lemon buttercream frosting:
- 16 tbsp. unsalted butter, at room temperature
- 2 tbsp. finely grated lemon zest
- 3 cups sifted confectionersâ€™ sugar
- 3 tbsp. fresh lemon juice
- Fresh raspberries, for garnish
- To make the cake, position a rack in the middle of the oven and preheat the oven to 350 degrees F. Butter and flour 2 9-inch round cake pans. Whisk together the flour, baking powder, salt, and poppy seeds in a bowl; set aside. In the clean, dry bowl of an electric mixer fitted with the whisk attachment, beat the egg whites on medium speed until foamy. Add the cream of tartar and increase the speed to medium-high. Beat just until stiff peaks form when the whisk is lifted. Transfer the egg whites to a separate bowl, clean the mixer bowl and reattach it with the paddle attachment.
- Add the butter to the mixer bowl and beat on medium speed until smooth. Gradually add the sugar and beat until incorporated. Mix in the lemon zest. Beat the mixture on medium-high speed until light and fluffy. Add ¼ cup of the milk and beat until just blended. Reduce the speed to low and add the flour mixture alternately with the remaining milk in three batches, beginning and ending with the flour, scraping down the sides of the bowl as necessary. Beat until just blended. Using a rubber spatula, fold one quarter of the egg whites into the batter, being careful not to deflate the mixture. Once incorporated, add in the rest of the whites and gently fold in until well combined.
- Pour the batter into the prepared pans and bake until golden and a toothpick inserted in the center comes out clean, about 25-30 minutes. Cool the cakes in the pan on a wire rack for 10 minutes. Run a thin knife around the outside of pans and gently turn the cakes out. Allow to cool completely.
- To make the raspberry curd, melt the butter in a large saucepan over medium heat. Add the raspberries, egg yolks, sugar and salt, and cook, mashing the berries. Stir frequently at first and then constantly at the end, until thickened, about 10 minutes. Pour the mixture through a coarse strainer set over a bowl, pressing hard on the solids to extract as much liquid as possible. Cool to room temperature; the curd will continue to thicken as it cools. Stir in lemon juice to taste. Cover and refrigerate until ready to serve.
- Layer the rounds with the cooled raspberry curd. Once layered, allow the assembled cake to cool in the refrigerator to help them set. In the meantime, make the frosting. In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and zest on medium speed until light and fluffy. Gradually add the sugar and beat until smooth. Add the lemon juice and beat for one minute longer.
- Frost the chilled cakes with the lemon frosting. Garnish with fresh raspberries as desired.
