Lemon Poppy Seed Cake
This post may contain affiliate links. Read my full disclosure policy.
Moist, tender, and unapologetically lemony, this cake pairs plenty of citrus with a generous scattering of poppy seeds.
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 melt-in-your-mouth texture is just what you’d hope for in a homemade loaf.
This lemon poppy seed cake 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: Gives the cake its structure while still allowing for a tender crumb. For accuracy, spoon it into your measuring cup and level it off with a knife.
- Baking Soda: Works with the acidity in the buttermilk and lemon juice to help the cake rise.
- Salt: Balances the sweetness and brings out the lemon.
- Poppy Seeds: Give the cake its signature look along with a subtle nutty taste and a little crunch.
- Low-Fat Buttermilk: Keeps the cake moist and tender while adding a slight tang that works especially well with the lemon. If you’d prefer not to buy it, check out some easy guidance on how to make buttermilk using milk and lemon juice or vinegar.
- Lemon Zest & Fresh Lemon Juice: Zest gives the cake its strongest lemony punch, while the juice is used in the cake, syrup, and glaze. It adds brightness to the batter, gives the syrup a tart edge, and turns the confectioners’ sugar into a tangy glaze.
- Unsalted Butter: Makes the cake rich and tender; softening it first allows it to cream properly with the sugar.
- Granulated Sugar: Sweetens the cake and is also used to coat the pan and make the lemon syrup that soaks into the baked cake.
- Eggs: Give the cake structure and richness and help hold the batter together.
- Confectioners’ Sugar: Whisked with lemon juice to make the simple glaze that goes over the cooled cake.

Step-by-Step Instructions
Step 1: Combine the dry ingredients. Whisk the dry ingredients together until evenly combined. Take a moment to make sure the poppy seeds are well distributed so they’re scattered evenly throughout the finished cakes.
Step 2: Combine the wet ingredients. Combine the buttermilk and lemon zest/juice. Don’t be concerned if the mixture looks slightly curdled after the lemon juice goes in—that’s completely normal.
Step 3: Cream the butter and sugar. Beat the butter and sugar until light and fluffy. Give this step a few minutes—the mixture should look noticeably lighter in both color and texture before you move on.
Step 4: Add the eggs and begin the batter. Beat in the eggs one at a time, then start incorporating the dry ingredients on low speed. Scrape down the bowl as needed so everything mixes evenly.
Step 5: Add some of the buttermilk mixture. Mix in the first portion of the buttermilk mixture. The batter may look a little uneven at this point, but it will come together as you continue adding the wet and dry ingredients.
Step 6: Finish the batter. Continue alternating the dry and wet ingredients, ending with the dry. Once the flour starts going in, keep the mixer on low and mix only until everything comes together; overmixing at this stage can make the cakes less tender.
Step 7: Fill the pans. Divide the thick batter between the prepared loaf pans and smooth the tops. Just eyeballing the amounts is fine, but if you happen to have a kitchen scale, you can use it to get the two loaves reasonably close.
Step 8: Bake and cool. Bake until the cakes are golden, and a tester inserted into the center comes out clean. Let them rest briefly in the pans before lifting them out to finish cooling on a rack. The short rest gives the cakes a chance to firm up.
Step 9: Make the lemon syrup. While the cakes finish cooling, make the simple syrup and stir in the lemon juice off the heat. You want the syrup to stay warm so it absorbs readily into the cakes.
Step 10: Make the glaze. Whisk together the glaze until smooth, adjusting the consistency if needed. It should be thick but pourable—closer to honey than a thin icing—so it stays on top of the cakes while still dripping down the sides.
Step 11: Soak and glaze the cakes. Slowly brush the warm syrup over the cooled cakes, giving it time to soak in as you go, then spoon the glaze over the top. Let the glaze set before slicing. The cakes keep well for a few days and can also be 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 (see note)
- 1 cup (2 sticks) 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 (175°C) and set an oven rack in the middle position. Spray two 8½ x 4½-in (22 x 11-cm) 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 to 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.
Notes
- If you’d prefer not to buy it, check out some easy guidance on how to make buttermilk using milk and lemon juice or vinegar.
- You'll need 3 large lemons for this recipe.
- Freezing 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.)

Great recipe. I can’t have a lot of sugar, so I used 1.5 cups, no syrup, a small amount of glaze to decorate. Perfect for my family. Great texture, flavour and looks good too. Thanks.
My husband and I love your recipes and was so happy to come across this one. Could I double the recipe and make a bunch of tiny loafs? If so, would the oven be the same temp. for mabe 1/2 hour or so ??? I’d like to give as gifts. Thank you so much.
So glad you like the recipes! These should work in mini loaf pans. The timing will depend on the size of the pans.
Followed the directions exactly, using a Bundt pan I have used many times successfully. However, this cake stuck so badly that I am left with a heap of broken pieces. And it tastes good but more like a muffin than a cake. Waste of ingredients.
Hi jen, I’ve made a lot of your recipes and they’re pretty much full proof ❤thankyou
I’m not sure what happened with this cake it was dry inside. I put the syrup did everything exactly like the recipe. I’ve been baking for years. Not sure what happened 🤔
Hi Angela, Sorry you had a problem with this. If you’ve been baking for years, you may already know about this, but dryness is usually caused by measuring the flour incorrectly. Did you use the spoon and level method to measure the flour? Even a few extra ounces can make a big difference. This article/video explains it nicely.
Amazing, amazing! Made this for a friend on her birthday and she told me her whole family devoured it in a few minutes!
What a terrific cake! I made the recipe exactly as written (choosing the option of greasing and lightly flouring my Bundt pan) and could not have been more delighted with the result. The cake was moist and lightly lemony and the proportion of poppy seeds spot on. I loved how they crackled a little as you bit into your slice of cake! I’m an experienced baker but have never found a Lemon Poppy Seed recipe I’ve been happy with until now. More than happy. It’s a GEM. Thanks for sharing it with us all Jenn!
Amazing! Just what my daughter ordered for her birthday! Great to have the additional notes about preparing the pan. Worked like a charm! So delicious and all from scratch!
Tried this recipe today it was a super hit. Everyone loved it. I followed the recipe exactly as the way it was.
This is an epic lemon poppyseed bundt cake recipe – crunchy outside and moist inside – it’s simply delicious!! Will be my go to lemon poppyseed recipe from now on
Oh my gosh! The first time I made this, my hubby practically ate the whole thing. The 2nd time I made, which is tonight, I gave it to a person who was down on their luck, but wanted to celebrate a special occasion. She was so thankful. She said it smelled so delicious. I ended up sharing your recipe with many others that saw what I made on FB. Your recipe was clear and thorough. Thank you so much!!
Holy moly, this cake was REALLY sweet! It was nice, but I needed a cup of black coffee to get it down. I guess as a children’s birthday cake it might be good. As a casual “something to munch on with your coffee” cake I might try cutting the sugar in half next time. Otherwise it was easy to put together and baked up nicely (and it looks pretty)
I made this cake this morning and we just had it for dessert. It was absolutely delicious! My whole family agreed. The texture is a perfect balance of moist and dense but still light. I used lemons from my garden and the balance of tart and sweet was on point. I’ll definitely make this cake again!
