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 Natasha,
    Firstly, your videos make me smile and brighten up my day :).

    Is there an ingredient that can be added to the frosting to stabilise it so, if I needed to travel with the cake the frosting will not melt and stay in-tack?

      Hi, I would bring it to room temperature for a bit before serving. Also, if you slice it, place a sheet of plastic wrap directly over the sliced part of the cake to keep it from drying out before putting it in the refrigerator.

      Everything I have ever made from your site has been phenomenal but this cake seemed to stump me a bit. It came out a bit dry and hard and not as fluffy? I’m not sure where I went wrong but we still enjoyed it with lots of whipped topping to combat the dryness!

        Hello Tammy. Lemon cakes are challenging because they tend to be dry. The softened butter and buttermilk were the key to adding moisture and great flavor to the cake so make sure that you used the right measurements of ingredients to achieve that moist that we want to achieve. I recommend trying it exactly as written. Thank you for sharing that with us, I hope it works out better next time.

    Is the texture of this cake supposed to be like a chiffon cake or more like a sponge or castella cake?

      September 29, 2020

      Hi, it is probably more like a combination of those two – something in between. It has a soft and airy texture but is more crumbly than chiffon.

    Greetings from Singapore! I hope all is well with you, Natasha. I can’t wait to try making this cake. I am quite the noob when it comes to baking. My oven can only hold one baking pan at a time. Is it ok to bake one layer of cake first, then wash out the pan when the first one is done, pour the remaining batter and bake? I guess my concern is that the batter that is waiting will change during the time the first batch is in the oven. And if this is ok, do I use a “9” or “8” inch cake pan? Thanks!

      Hi! 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. I worry the batter will deflate if you make the entire recipe and have one pan sitting while the other is baking. If you experiment, please let me know how it goes.

    I will admit that I didn’t plan to like this as much as I do!

    I consider myself a good cook and a decent baker, but cakes have never been my strong suit. They usually just turn out so-so and I wonder why I bother when I could get good results from a boxed mix.

    Anyway… I usually bake a birthday treat for my family members and my sister-in-law sent me a link to this recipe a couple of weeks ago. It is her birthday this week, so I figured it was a hint. I followed this recipe exactly and all the hints too… The cake turned out great and the frosting is divine.

    I don’t usually love lemon cakes because they don’t have enough zing. I considered a lemon filling for this, but decided to try the recipe as-is. I was not disappointed. The lemon is so fresh and bright and has just enough tart. Super yum! (Ijust finished off the last piece for breakfast this morning)
