Tender lemon poppy seed cake layers drizzled with lemon syrup and topped with a tangy cream cheese frosting.
I’ve said it before, I am a HUGE fan of lemon desserts. More so than any other flavor. If there is a lemon dessert on the menu you can bet I’m ordering that over something chocolate (unless it’s panna cotta, no thank you jello-like texture). There is just something about the sweet and tangy flavor that has me coming back for more.
Today, I’m bringing you the classic combo of lemon and poppy seeds in layer cake form. Oh and it’s paired with my delicious new cream cheese frosting recipe for good measure.
How to Make Lemon Poppy Seed Cake
To make this Lemon Poppy Seed Cake I started with my favorite Lemon Cake recipe and tweaked it a bit. I added poppy seeds (obviously) and a bit more zest but also reduced the sugar a bit.
Making the cake layers follows the traditional creaming method but the key difference here is that you should cream the lemon zest with the butter and sugars. This helps release all of those delicious and flavourful oils from the zest. Don’t skip this step and just opt to toss it in at the end!
Cake Tip!
Cream the lemon zest with the butter and sugar to release the oils from the zest and amp up the lemon flavor.
I experimented with adding more poppy seeds (I like my lemon poppy seed cake heavy on the poppy seeds) but that made the cake a little bit denser than I’d like. You wouldn’t think adding an extra Tbsp of poppy seeds would make a big difference but they do tend to absorb some of the moisture from the cake so I’m keeping the recipe at two which is the perfect balance.
To give the cake even more of a lemony punch I made an easy lemon simple syrup to brush onto the cake layers. This will make the cake sweeter though which is why I cut back on the sugar from the usual 1 1/2 cups to 1 cup.
To use the syrup it’s best to trim the crust off the top of the cake. I don’t usually need to trim my cakes — they bake nice and flat because I use baking strips — but for best syrup absorption I find trimming off that top crust is ideal. That or you can poke holes into the cake with a skewer if you prefer. Then simply dip a pastry brush into the syrup and brush each of the cake layers generously.
Stable Cream Cheese Frosting
In my most recent post I gave you the details of how to make cream cheese frosting more stable and I’ve used that recipe here. Cream cheese frosting is such a perfect pairing for Lemon Poppy Seed Cake!
I’ll let you head over to that post to read the ins and outs but it comes down to order of ingredients, temperature, and stabilizing agents.
I hope you all love this cake as much as we did. It’s the perfect spring cake and would be wonderful for Mother’s Day!

Instructions
Lemon Poppy Seed Cake:
- Preheat oven to 350F. Grease and flour three 6" cake rounds and line with parchment.
- In a medium bowl, whisk flour, poppy seeds, baking powder, and salt until well combined. Set aside.
- Using a stand mixer fitted with a paddle attachment, cream butter and lemon zest until smooth. Add sugar and beat on med-high until pale and fluffy (approx 3mins).
- Reduce speed and add eggs one at a time fully incorporating after each addition. Add vanilla.
- Alternate adding flour mixture with milk & lemon juice, beginning and ending with flour (3 additions of flour and 2 of milk & lemon juice). Fully incorporating after each addition.
- Spread batter evenly between the prepared pans and smooth the tops.
- Bake for about 30-35mins or until a toothpick inserted into the center comes out mostly clean.
- Place cakes on wire rack to cool for 10mins then turn out onto wire rack to cool completely.
Lemon Simple Syrup:
- Place lemon juice and sugar into a small saucepan, stir to combine. Cook over medium heat, stirring often, until simmering and all sugar has dissolved. Cool completely before using on cake.
Cream Cheese Frosting:
- Using a stand mixer or hand mixer beat butter until pale and creamy.
- Reduce speed to low. Add powdered sugar 1 cup at a time and mix on low until well blended. Increase speed to medium and beat for 3 minutes. Add vanilla and continue to beat on medium for 1 minute.
- Slowly add chilled cream cheese one cube at a time (about 1 tablespoon at a time). Beat well until blended and ensure no lumps of cream cheese remain.
- If needed, add cornstarch or meringue powder 1 tablespoon at a time to stiffen the frosting (I didn't but this is an option). Add a pinch of salt to cut some sweetness if desired.
- Run mixer on low for a couple of minutes to remove any air bubbles.
Assembly:
- Trim the crust off the top of each cake layer and brush each with the lemon simple syrup. About 1-2 Tbsp per layer.
- Place one layer of cake on a cake stand or serving plate. Top with 2/3 cup of frosting, spread evenly. Repeat with the remaining layers and apply a thin coat of frosting all over the cake. Chill for 20mins.
- Use the remaining frosting to frost the cake in a rustic manner.
- Decorate with fresh, edible flowers and lemon slices if desired.
Chelsea says
Hi,
How long do your cakes last at room temp? Or are they required to be kept in the fridge?
Olivia says
Hi Chelsea! I generally recommend refrigerating but they should be fine at room temp for a couple of days. The frosting will get quite soft though.
Abby says
Hi! Do you think that your vanilla swiss meringue buttercream would taste okay with this?
Olivia says
Hi Abby! Yes, I think it would be delicious.
sam says
I have made a cake from this site before and it was great. I made the lemon poppyseed cake and my cakes (6in pan) are maybe a centimeter thick! I am confused at what happened this has never happened before when baking for me
Olivia says
Hi Sam! It definitely sounds like something went wrong. The cakes should be close to 1.5″ (~4cm) tall each. Did you use three 6″ pans? Did you adjust the recipe in any way? I would check to make sure your baking powder is still fresh otherwise. That could cause the cakes to not rise. Did you include baking powder? 1cm thick almost seems like they didn’t rise at all.
Megan says
Hi Liv, I would love to add lemon curd, could I replace the lemon syrup and just use the lemon curd between the layers instead?
Olivia says
Hi Megan! You can use both if you want an extra kick but you can definitely replace it. Be sure to make a stiff border with the buttercream to hold the curd in.
Rudolph Loehndorf says
can I use your lemon buttercream recipe on this cake.
Olivia says
Hi Rudolph! I don’t have a lemon buttercream recipe, but it should work fine.
Rudolph Loehndorf says
can I add chopped pecans to this recipe thank you for the information.
Olivia says
Hi Rudolph! I’m not sure how that would go flavour-wise, but you can definitely add them. Be sure to toss them in flour first and fold them in gently at the end.
Kara Ross says
It was amazing! How could I make this a sugar free recipe?
Olivia says
Hi Kara! So glad you loved it. I have not tried it myself with sugar substitutes so I can’t give specific recommendations.
Lisa says
I used 2 8″ cake pans. Layers came out thin and very dense. Had to make a second batch, came out the same. Why did this happen?
Olivia says
Hi Lisa! The cakes should be close to 1.5-2″ tall each in two 8″ pans. If they were shorter than that I would check to make sure your baking powder is still fresh. Also make sure not to overmix the cake batter as this can cause shorter, denser cakes.
Kirsten says
I had the same problem Lisa. Second try for two more layers I limited mixing and got the same result. I wonder if the cake strips helped cause this. It’s going to be a 4-layer cake!
Amber says
Looks amazing! How long can the finished cake sit in the fridge prior to eating? Or does it sit out at room temperature? Can I fully finish it the day before?
Olivia says
Hi Amber! It will be fine in the fridge for 2-3 days, after that it will start to dry out. You can definitely finish it the day before. Just take it out of the fridge 2-3 hours before serving so it can come to room temp.
Avni says
Hi! Im looking forward to making this cake for a friends birthday. I wanted to use a stencil on the frosting, and i was wondering if the frosting would be firm/dry able to support that?
Olivia says
Hi Avni! I have not tried stenciling on cream cheese frosting before so I can’t say for sure. It does crust over though due to the powdered sugar.
Debbie howe says
Hi. Lovely recipe. Can this be used as one of a tier for a wedding cake. Will it stack ok
Olivia says
Hi Debbie! As long as the tiers are properly supported it should be fine.
Jacquie says
Hi Liv!! Reading this post has me salivating for this lemon poppy seed cake. I love lemon too and was my Dad’s favourite. I love how you decorated it too. Looks so fresh and bright and very delicate. My hubby is now T2 diabetic and I have been finding recipes to use almond flour instead of all purpose and using erythritol instead of regular sugar. Do you have any experience with substituting these? If so, could I do a measure for measure for these lemon poppy seed cake?
Olivia says
Hi Jacquie! Thanks so much for your sweet comment, I’m so happy you love it! I have subbed almond flour, but only for half of the flour not all of it (you need something to account for the gluten. Can he do GF flour? You should be able to replace all of the AP flour for a proper AP GF flour blend. I have not used sugar substitutes but I think that would be less of an issue. For subbing that just use whatever it says on the package. Not sure if it’s one for one but it often is. Let me know how it turns out!
Jacquie says
Hi Liv! Thanks for your response. GF flour is made with rice flour (I’ve learned that rice, potatoes, ap flour,pasta all convert to sugar (grrr!) Anyway, the recipes that I’ve made with almond flour also uses either xanthum gum or cocunt flour. Cakes don’t rise as much but they are still tasty. I have earmarked this recipe to try at our next family function. I will send a pic and let you know how it goes and tastes!!
Olivia says
You can try it will all almond flour but do add some of the xanthan gum as that helps mimic the gluten. Let me know how it turns out!
