Lemon Poppy Seed Cake

This lemon poppy seed cake is bursting with bright citrus flavor, packed with nutty poppy seeds, and drizzled with a tangy lemon glaze—perfect for sharing (or not!).
A variation of my popular lemon pound cake, this lemon poppy seed cake is laced with fresh lemon zest, filled to the brim with nutty, crackly poppy seeds, and drizzled with a bright lemon glaze. The texture is just what you hope for in a homemade cake—ultra-moist and melt-in-your mouth tender.
The recipe yields two loaves that stay fresh for days. My grandmother would have called it “company cake” since it’s the perfect treat to have on hand when friends and family come over. And if you love the lemon and poppy seed combo, don’t miss my lemon poppy seed muffins!
(Note: This recipe was originally a Bundt cake, but due to readers having issues with sticking, I updated it in January 2025 to loaf pans, which can be lined with parchment for easy removal.)
“The cake was moist and lightly lemony and the proportion of poppy seeds spot on…It’s a GEM.”
What you’ll need to Make Lemon Poppy Seed Cake
- All-purpose flour – Provides structure and gives the cake its tender crumb.
- Baking soda – Helps the cake rise by reacting with the acidity in the buttermilk and lemon juice.
- Salt – Enhances flavor and balances the sweetness.
- Poppy seeds – Add a nutty flavor and subtle crunch, giving the cake its signature texture.
- Buttermilk – Keeps the cake moist and tender while adding a slight tang that complements the lemon.
- Lemon zest – Infuses the cake with bright, aromatic lemon flavor.
- Fresh lemon juice – Adds a fresh, tangy citrus punch to both the cake and the glaze.
- Unsalted butter – Provides richness, moisture, and a soft texture.
- Granulated sugar – Sweetens the cake and the syrup that keeps it extra moist.
- Large eggs – Bind the ingredients together, add moisture, and contribute to a light, fluffy texture.
- Confectioners’ sugar – Used in the glaze to create a smooth, sweet finish that enhances the lemon flavor.

Step-by-Step Instructions
To begin: In a medium bowl, combine the flour, baking soda, salt, and poppy seeds. Whisk well and set aside.
In a small bowl, mix the buttermilk, lemon zest and lemon juice. Set aside.
In the bowl of an electric mixer fitted with the paddle attachment (or beaters), combine the butter and sugar. Cream on medium speed until light and fluffy, 3 to 4 minutes.
Scrape down the sides of the bowl, then add the eggs one at a time, beating well after each one. Give the bowl another quick scrape, then, with the mixer on low, beat in a quarter of the flour mixture.
Add one-third of the buttermilk mixture.
Beat in another quarter of the flour mixture, then a third of the milk mixture. Keep going—another round of flour, then the rest of the milk. Finally, mix in the last of the flour. Scrape down the sides and bottom of the bowl, then give it a quick mix to make sure everything is fully combined.
Spoon the batter into the prepared pans and smooth the tops.
Bake for 55 to 65 minutes, or until the top of the cake is golden and a cake tester comes out clean. Cool the loaves in the pan for ten minutes on a rack.
While they cool, make the syrup. Combine the water and granulated sugar in a saucepan and bring to a boil. Remove from the heat and stir in the lemon juice.
Make the glaze: in a medium bowl, whisk together the confectioners’ sugar and lemon juice until smooth.
When the cakes are cool, gradually brush the warm syrup all over the cakes, including the sides, letting it soak in as you go. Finally, spoon the glaze over the top of the cakes, letting it drip down the sides. Let the glaze harden before slicing. The cake will keep nicely for 3 days or frozen (without the glaze) for up to 3 months.

Ingredients
For the Cake
- 3 cups all-purpose flour, spooned into measuring cup and leveled-off with a knife
- ½ teaspoon baking soda
- ½ teaspoon salt
- ¼ cup poppy seeds
- 1 cup low-fat buttermilk (see note)
- Finely grated zest of 3 lemons (about 3 gently packed tablespoons)
- 2 tablespoons fresh lemon juice
- 2 sticks (1 cup) unsalted butter, softened
- 2¼ cups granulated sugar, plus more for the pan
- 3 large eggs
For the Syrup
- 2 tablespoons water
- 2 tablespoons granulated sugar
- 2 teaspoons fresh lemon juice
For the Glaze
- About 1 cup confectioners' sugar
- 2 tablespoons fresh lemon juice
Instructions
- Preheat the oven to 350°F and set an oven rack in the middle position. Spray two 8½ x 4½-inch loaf pans with nonstick cooking spray. Line the long sides of the pans with parchment paper “slings” and spray lightly with nonstick cooking spray again.
- In a medium bowl, whisk together the flour, baking soda, salt, and poppy seeds. Set aside.
- In a small bowl, combine the buttermilk, lemon zest and lemon juice. Set aside.
- In the bowl of an electric mixer fitted with the paddle attachment (or beaters), cream the butter and sugar on medium speed until light and fluffy, 3-4 minutes. Scrape down the sides of the bowl, then beat in the eggs one at a time, beating well after each addition. Scrape down the sides of the bowl again. With the mixer on low speed, beat in one-quarter of the flour mixture, then one-third of the buttermilk mixture. Beat in another quarter of the flour mixture, then another third of the milk mixture. Repeat with another quarter of the flour mixture and the remaining milk mixture. Finally, beat in the remaining flour mixture. Scrape down the sides and bottom of the bowl, and give a quick mix with a rubber spatula to make sure all of the ingredients are well incorporated.
- Spoon the thick batter into the prepared pans and smooth the top with a rubber spatula. Bake for 55 to 65 minutes, or until the top of the cake is golden and a cake tester comes out clean. Cool the cake in the pan for ten minutes on a rack.
- Set the cakes on a cooling rack, and cool in the pans for 10 minutes. Carefully run a knife along the unlined sides of the pans to loosen the cake from the pan. Using the parchment slings, lift the cakes out of the pans and place onto the rack, leaving the parchment paper in place under the cakes. Let cool for about 1 hour.
- When the cakes are almost cool, make the syrup. Combine the water and sugar in a saucepan and bring to a boil. Remove from the heat and stir in the lemon juice.
- When the cakes are cool, carefully transfer them to serving platters.
- Gradually brush the warm syrup all over the cakes, including the sides, letting it soak in as you go.
- To make the glaze: in a medium bowl, whisk together the confectioners' sugar and lemon juice. Add more confectioners' sugar or lemon juice as necessary to make a thick but pourable glaze (it should be a little thicker than you'd think, about the consistency of molasses or honey). Spoon the glaze over the top of the cake, letting it drip down the sides. Let the cakes sit for about one hour to allow the glaze to set before serving.

- Note: You'll need 3 large lemons for this recipe
- Freezer-Friendly Instructions: The cake can be frozen (without the glaze) for up to 3 months. After it is completely cooled, double-wrap it securely with aluminum foil or plastic freezer wrap, or place it in heavy-duty freezer bag. Thaw overnight on the countertop before serving. (Add the glaze after the cake is thawed.)

I hope I can find my saved copy of the Bundt version, because I don’t want to make this in loaf pans and have always made it very successfully using the original recipe.
Would be great if you can offer both methods, unless the measurements haven’t changed?
Hi Melissa, I’ll email you the original version.
Are you able to send me the Bundt version too?
Yep!
I almost never comment but this recipe was a winner with the whole family! Will definitely be making this again and you should too. Best part is you don’t have to soak the poppy seeds!
I was looking for a lemon cake that used fresh lemon juice instead of lemon extract. I had poppy seeds on hand and made the buttermilk using fresh lemon juice as your hint recommended. This is a fantastic, easy to make cake! The fresh lemon juice was just perfect. I only used the simple syrup on top as it didn’t need frosting. This lemon poppy seed cake lives up to the reviews and is definitely company cake!!
I made this cake and it was amazing. I followed the recipe to make my own buttermilk and it turned out perfect. The lemon intensity was really right on, but I am going to make it again next week and increase the lemon to water ratio in the syrup and glaze, and increase the lemon zest in the cake because I want to make it a little more intense because I’m curious. The recipe was easy and instructions were well written and easy to follow. Thank you for this lovely recipe!

Made this last night and I had no problems with the recipe, the only problem I had was I couldn’t wait for it to cool before applying the glaze. It of course just melted, but when I served this I place fruit (Blueberries and Lemon Slices) with whipped creme and it came out so good that I was asked to serve seconds! Since I’m Diabetic I couldn’t eat it and today I plan to follow the same recipe but instead of sugar, I’ll be using Splenda or other sugar substitute. Oh, and on a second note: I used the jar of Poppy seeds!
Great recipe, thank you for sharing.
Hi Carmen !
I love how you served the cake! It sounds delicious (I’m not surprised there were requests for more!).
We’re not diabetic, but I’d be really interested to hear how the recipe turned out using SPLENDA😊.
Lisa in Laton
I want to make this today with monkfruit sweetener. Did it turn out with the Splenda? Did you make any adjustments?
Followed each step carefully and got decent Bundt cake mould – it was 110% worth it!!! We had sleepover during Christmas holiday and this loaf was a BIG HIT for our family of 20 people for chrismats morning breakfast!! LOVE LOVE LOVE
