Lemon Poppy Seed Cake is soft, moist, simple to make and loaded with fresh lemon flavor. The lemon buttercream had me licking the spatula, the bowl, the piping bag…

Our love of poppy seed desserts is obvious, from our Poppy Seed Cake to Mom’s Poppy Seed Roll. And the fresh flavor of lemon really amps up desserts, like these lemon-glazed blueberry muffins. The combination of poppy seeds and lemon is pure bliss.

Lemon Poppy Seed Cake Recipe:

Lemon cakes are challenging because they tend to be dry. We made cake after cake until we landed on this combination which produced a moist cake with a soft crumb studded with poppy seeds and subtle and lovely lemon flavor. The softened butter and buttermilk were the key to adding moisture and great flavor to the cake.

Can I Substitute the Fresh Lemon Juice?

Fresh lemon juice is critical in this lemon cake and all you need is a total of 2 large lemons for the cake and frosting. Using both the zest and the juice will give you the best lemon flavor. Lemon juice from concentrate just won’t be the same. We haven’t tried lime but it’s worth experimenting for a lime flavored cake.

Can I Make this Lemon Poppy Seed Cake Ahead?

This Lemon Poppy Seed Cake refrigerates well and we actually prefer it chilled for an hour or so for easier slicing. The little bit of cream cheese in the frosting keeps it from firming up too much in the fridge so you can serve it chilled or at room temperature.

How to Store A Cake:

  • Plain cake layers – cool completely to room temperature then wrap fully in several layers of plastic wrap and keep at room temperature up to 2 days, refrigerate up to 5 days, or freeze up to 3 months.
  • Frosted cakes – cover with a cake keeper (here’s ours) or use a large overturned bowl or even pot (just be sure it has enough clearance for the width and height of the cake. Refrigerate cakes covered to keep them from drying out or absorbing refrigerator odors.
  • Sliced Cake – once a cake has been cut, it starts to lose moisture. To keep it fresh, lay a piece of plastic wrap against the cut side then cover as you would whole frosted cakes (see above).

How to Make Lemon Buttercream:

The secret to the best lemon buttercream frosting is adding just a little bit of softened cream cheese. It balances the flavor, enhances the lemon and makes the texture luxuriously whipped, velvety smooth and perfect for piping onto cakes. A pop of fresh lemon flavor cuts the sweetness and makes it irresistible. This lemon frosting couldn’t get any easier:

  1. Cream butter then beat in cream cheese until smooth
  2. Add powdered sugar, vanilla and fresh lemon juice
  3. Beat 5 minutes on high speed until whipped and fluffy

Pro Cake Baking Tips:

  1. Have all of your moist ingredients at room temperature. Butter, eggs, lemons and buttermilk should be at room temperature before using. Room temperature ingredients incorporate much easier for an even-textured batter and improved rise. When to take ingredients out? Timing depends on your room temperature so take ingredients out at least 1 hour before or 2 hours before to be sure.
  2. Read through the recipe before starting so you know what tools are needed for a recipe and aren’t frantically looking for that whisk when you need it.
  3. Pre-measure everything so it’s ready to add as you follow the recipe.
  4. Measure ingredients correctly – use the correct measuring cups and spoons for wet or dry ingredients. The way you fill matters, i.e. for flour, use the spoon and scrape method instead of plunging your measuring cup into a bin which can give you 25% more flour, resulting in a dense cake.
  5. Keep the oven door closed, opening it only to test for doneness at the end.

Instructions

How to Make Lemon Poppy Seed Cake:

  • Preheat oven to 350˚F with a rack in the center of the oven. Butter the sides and base of two 9" cake pans and line the bottom of each pan with a ring parchment paper.
  • In a large mixing bowl with an electric hand mixer, cream together 12 Tbsp softened butter and 1 cup sugar for 2 minutes on high speed. Add eggs one at a time mixing just until incorporated.
  • In a small bowl, whisk together 2 cups flour, 2 1/2 tsp baking powder and 2 Tbsp poppy seeds. Add half of the flour mixture, mixing just until incorporated.
  • Add 1 Tbsp lemon juice, 1 Tbsp lemon zest and 1 tsp vanilla, mixing just to combine. With mixer on low speed, add 1/2 cup buttermilk then mix in remaining half of the flour mixture, mixing until no lumps remain. Divide between 2 prepared pans and spread evenly. 
  • Bake at 350˚F for 20-23 minutes or until a toothpick inserted into the center comes out clean. Let cake cook in pans 10 minutes then transfer to wire racks, remove backing and and cool to room temperature.

To Assemble and Frost the Cake:

  • Once completely cooled, place the first cake layer on a cake platter and spread a generous 1/3 of the buttercream frosting over the top. Place the second layer of the top (flat-side-up) and spread 1/3 of the frosting over the top and sides.
  • Sprinkle the edges of the cake with poppy seeds if desired. Pipe remaining 1/3 of the frosting as desired over the top and place a slice of fresh lemon over each puff of frosting.

How to Make Lemon Buttercream Frosting:

  • In a large mixing bowl with an electric hand mixer, beat 1 cup butter on high speed until smooth and creamy (2 min). Add 4 oz softened cream cheese and beat until completely smooth. Add 4 cups powdered sugar, 3 Tbsp lemon juice and 1 tsp vanilla and beat on high speed until whipped and fluffy (5 min).

    Hi! I’m planning to make this cake, can I use cake flour instead of all-purpose flour? 🙂

      Hi Careal, this recipe is really soft without cake flour, so I don’t think it needs it, but I haven’t experimented with cake flour to advise it will work if you happen to test that; I would love to know how you like it.

    Hi!
    Is the icing recipe enough to fully frost a 2 layer 9” cake, or only ‘naked’ frost?
    Thanks!

      Hi Lisa, we enjoyed it that way, but you can definitely use less frosting at the top and between the layers to have more coverage on the sides.

    The lemon poppyseed cake, it’s so good, but dry tasting, can a vanilla pudding be added for moisture ? If so, do we need to add something else ?

      Hi Wanda, I haven’t tried adding vanilla pudding but that could be tasty. Make sure to brush with syrup and avoid over-baking or adding too much lemon which can dry the cake out.

    Hi Natasha—
    Just wanted to let you know I made the Lemon Poppy Seed last night. It was a little dr. I left it in 23 min and probably should have taken it out in 21 min. BUT still delicious. My frosting was sitting out too long while cake was cooling. Ran out for a church service not thinking about putting in refrigerator before leaving.go to church. My icing around edge not as I would have liked but I never tried doing a decoration before so I am pretty happy with it all. I took a picture but not sure how to send it.🙂💐

      Thank you so much for sharing that with me; I’m so happy you’re enjoying my recipes! If baking in 8″ tins, you would need to bake longer – probably closer to 23 minutes or until a toothpick inserted in the center comes out clean.

      Hi Sye, I haven’t tested it that way, but you would probably need a tall-walled (3″ at least) springform pan if using one so it doesn’t overflow. If you experiment, please let me know how it goes.

    I found this recipe very easy to follow but I was disappointed with the result. I followed the recipe to a T and I do have darker pans so I always check on the layers early. I baked these for 18 minutes about and they were very, very dry. I added raspberries fo bring some moisture which helped. The lemon flavor comes through but even freshly baked it was so dry it seemed stale. I also thought the layers would be taller they seemed very flat. Any advice would be so helpful!

      Hi Isabel, If it seems overly dry, it could be due to overbaking. Also, make sure not to add too much lemon juice. I’m not sure if it was the case, but if baking in a larger pan, the layers would be flatter and would require less time to bake.
