This was drop-dead delicious! I stuck to the recipe as written but halved the glaze amount. I poured the glaze over the cake while it was still warm and still in its pan. It soaked in beautifully. I let it cool completely before removing it from the pan.”

Flour Blends Tested:
1. King Arthur Measure for Measure—This blend works really well in my recipes. I don’t have to let the flour blend rest in the batter.
2. Bob’s Red Mill 1:1 Blend—This blend also works well, but this flour blend does benefit from resting the batter for 15 minutes before baking. The rest allows the rice flour in this blend to soften, so you don’t have gritty baked goods.
Ingredient Notes:
- Gluten Free Flour Blend – If your gluten free flour blend doesn’t contain xanthan or guar gum, add ½ a teaspoon. You can read more about my best gluten free flour recommendations and testing.
- Baking Powder and Soda – This recipe contains both. They help give a nice rise to this cake. Use aluminum-free baking powder.
- Poppy Seeds – Use any brand, but read the ingredients to ensure it is just the seeds.
- Eggs – Use size large.
- Coconut Oil – I used this, but you can use another light oil. I also like avocado and canola oil.
- Milk – I used almond milk to keep this lemon poppy cake recipe dairy-free. You can use any plant-based milk you like or regular milk. You can read more about what plant-based milk is gluten free.
You can even make this into gluten free lemon poppy seed muffins!
Tips For Sucess
1. I recommend using a spoon or leveling method to measure your gluten-free flour. Put the measuring scoop into the flour and fill it. Do not pack the flour. Use a knife to scrape along the top to remove the extra flour. You can also use a spoon to fill the measuring cup. Use a knife to level along the top to remove the extra flour.
2. Let the cake batter sit in the loaf pan for 20-30 minutes. This will soften the rice flour in the batter, making the cake less gritty.

Step-By-Step Photos and Directions:
Step 1: Preheat the oven to 350º F. Add the dry ingredients, including the flour, almond flour, sugar, baking powder, baking soda, salt, and poppy seeds, to a large
Step 2: In a separate smaller bowl, mix the wet ingredients, including the coconut oil, vanilla, eggs, lemon juice and zest, and non-dairy milk. Whisk.
Step 3: Pour the wet ingredients into the dry ingredients and gently mix. Don’t overmix the batter for best results because this can make your poppy seed cake denser.
🔑 Sandi says: I do NOT recommend a stand mixer. It will overmix your batter, leaving you with a dense cake.
Step 4: Spray a loaf pan with gluten-free baking spray. Pour the batter into a bread loaf tin and bake at 350º F for 40-50 minutes until done. The actual baking time can vary depending on the size and depth of your loaf pan.
You can test if your gluten-free lemon poppy seed loaf is done by inserting a toothpick into the middle of the cake. If the toothpick comes out clean, it is finished baking! This is called the toothpick test!
Try these fun topping ideas:
- Lemon glaze (a much runnier version of my lemonade icing; you want the lemon juice and sugar to absorb into your cake.)
- Vanilla frosting
- Cream cheese frosting

Frequently Asked Questions:
The poppy seeds are optional, so feel free to omit them if you don’t have them.
This lemon poppy seed cake will keep fresh for up to 4 days in the refrigerator. I don’t recommend storing it on the counter, as gluten-free foods tend to spoil much quicker.
You can freeze this lemon loaf cake. To freeze it, wrap the cooled loaf in plastic wrap tightly. Next, wrap it in foil. Place the bundle into a freezer bag. It will stay in the freezer for about three months.

Fluffy Gluten-Free Lemon Poppy Seed Cake
Ingredients
- 1 ½ cups gluten free flour * see note
- ½ cup almond flour * see note
- â…” cup cane sugar
- 2 tablespoons poppy seeds
- 1 teaspoon baking powder aluminum-free
- ½ teaspoon baking soda
- â…› teaspoon salt
- 2 large eggs
- ¼ cup coconut oil or another oil
- 4 tablespoons lemon juice
- 2 tablespoons lemon zest
- 1 teaspoon pure vanilla extract
- ½ cup dairy-free milk
For Icing:
- â…” cup powdered sugar
- 2 tablespoons non-dairy milk
- 3 tablespoons lemon juice feel free to adjust this if you want your icing thicker or runnier.
Instructions
- Preheat the oven to 350º F. Grease a bread loaf pan with gluten-free baking spray, coconut oil, or butter.
- In a large mixing bowl, add all dry ingredients and whisk to blend them together.
- In a smaller bowl, add all wet ingredients, including zest and whisk to mix. If your coconut oil is solid, melt it for 20 seconds in the microwave oven.
- Pour the wet ingredients into the dry ingredients and mix. Don't overmix or your cake will not be as light and fluffy. Optional: Let the cake batter sit for 20-30 minutes. This allows the rice flour to soften so the cake is not gritty.
- Bake the lemon cake for 30-40 minutes, or until done. Insert a toothpick into the top middle to test. If the toothpick comes back clean, the cake is done baking. If you see batter or crumbs, bake a little longer. The baking time can vary depending on the size and depth of your loaf pan.
- Allow the cake to cool completely on a cooling rack.
- In a bowl, add icing ingredients and mix. Drizzle on top of the cake and enjoy!
Notes
- I have tested this recipe with King Arthur Measure for Measure GF and Bob’s Red Mill 1 to 1 GF blend. That doesn’t mean others will not work; I just have not tested other flours.
- If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add ½ teaspoon.
- I highly suggest using almond flour and not almond meal. Almond meal is coarser and will make your cake grainy.
- To test for doneness, insert a toothpick into the center of the loaf. If the toothpick comes out clean, it is done baking. If you see batter or crumbs, the cake needs to bake longer.
- I used almond milk, but other dairy-free kinds of milk will work, but I do not recommend canned coconut milk.
- This cake will keep up to 4 days in an airtight container, or up to 4 months in the freezer.
SPECIAL NOTE
Please know that every gluten free flour blend has a different starch to grain ratio. If you use a blend I didn’t test, you may need to adjust your moisture levels in your baked goods.

Hello, do you have any substitutions for the coconut oil? Can’t tolerate coconut unfortunately.
Hi Molly, you can use a light oil like cannola or avocado. Thanks for writing!
Hi! Do you think that this recipe could be made in a bundt pan?
You can definitely make this in a bundt pan, but you will need to bake it longer.
I love this recipe and I’m making it for my partner’s birthday party this week because he’s obsessed with it. Thank you! Just a quick question:Ccould you share with me the ratios for the original glaze with butter? It worked so well for me the first time, and I can’t imagine the flavor without butter. Much appreciated!
Hi Hannah, it was 1/4 cup of butter I believe. Tell your partner happy birthday from us!
This was drop-dead delicious! I stuck to the recipe as written but halved the glaze amount. I poured the glaze over while the cake was still warm and still in its pan. It soaked in beautifully. I let it cool completely before removing it from the pan. I found it needed a full 40 min to test fully baked. Tender, moist, amazing. Thank you so much!
I am so glad you liked it Dana, you made my day!
Hi again! I’m back to bake this a second time because we devoured the first double batch. Why did you remove the butter from the topping?! I think it was genius and will still make it that way because we loved it. Also, I noticed that in your description near the top you mention to bake for 40 minutes (which is what worked for me) but in the actual directions you state to bake for 30.
Love this recipe.
Dana
You are so sweet Dana. I am finding the butter topping only works if someone uses the specific gluten free flour blend I used, King Arthur Measure for Measure. When someone uses a higher starch content blend, the recipe didn’t work with the butter topping so I took it out. There are just too many gluten free flour blends and when some don’t work with a recipe…it frustrates people.
Thank you for this fabulous recipe! I just made it and I don’t think anyone would be able to tell that it’s gluten free. I did use half and half in place of almond milk, only because I was out. It turned out great.
I am so glad you liked it Barbara 🙂
By using the coconut oil, does that mean it is gluten free, and dairy free?
This recipe is dairy-free as well as gluten free. Thank you for stopping by Lynne 🙂
Hi Sandi, can you use butter instead of the coconut oil?
Thanks!
Hi Nikita, I assume butter should be fine in this muffin recipe. I use the two interchangeably. Please come back and let me know how it turned out.
Great recipe. Before Celiac I had a Poppyseed bread recipe that I loved and this turned out very similarly. I did leave out the lemon juice and added an equal amount of liquid, but the key to my rave-reviewed bread is the glaze: 1/2 C sugar, 1/4 C orange juice, !/2 tsp each vanilla, almond, and butter extracts. (the same flavorings go into the batter as well). Poke the bread after it’s out of the oven for 10 minutes and pour the glaze over so it soaks in while warm. Be sure to get GF flavorings.
This sounds fabulous Molly 🙂
Sandy, I just found this recipe on Pinterest today. I’m so excited to try it, but I’m wondering if you have ever substituted the almond flour with anything else? I just received an assortment of flours through nuts.com that i am anxious to try but know nothing about them and what would be a better option. Brown rice flour, potato flour, cassava flour, and banana flour. Any suggestions?
Hi Kris, you can definitely make this recipe without almond flour. Instead of 1/2 cup almond flour, use an additional 1/4 cup of the gluten free flour blend. I like Cassava flour, but it is very light, starchy, and absorbs liquid a little more. I like brown rice flour…if it isn’t ground superfine it can add a slight grit to the texture, depending on brand. Authentic Foods brand gluten free flours are milled superfine so I use their brown rice flour. I have a bag of banana flour, but I haven’t experimented with it. Thank you 🙂
Thank you so much for this recipe! In my husband’s family, they made a lemon poppyseed cake for every birthday, but since my husband had to go gluten-free two years ago, I haven’t had the nerve to try to make one. I baked this today, and it actually turned out even better than the old family recipe (which for me usually turned out flat). The whole family was so impressed, and my husband was thrilled!
You made my day Ashley. I am so glad your family loved these muffins. Thank you for taking the time to come back and let us know :-).
Hi Sandi, I was about to try your recipe and noticed that there is no butter or oil. Is the recipe meant to be oil and butter free? Thanks!
That is so odd, thank you for pointing this out. There should be 1/4 cup coconut oil in this recipe. I added it back in. Thank you so much!
This cake looks so delicious and you’d never think it was gluten free. I will definitely be sharing with all of my girlfriends that are gluten free!
Thank you so much Jessica 🙂
Love having a delicious option for GF cake!
Awesome Suzy, enjoy 🙂
Wow, this Lemon Poppy Seed Cake so cute! I would love to eat this for breakfast, lunch and dinner! Thank you for sharing this great recipe! YUM!
LOL, my kids would love this lemon poppy seed cake for dinner too!
I am loving this recipe. My son has Celiac Disease and we are forever creating new GF baked goods. Personally, I would love this for breakfast with my coffee and for dessert anytime. I’ve always loved the lemon-poppy seed combination.
I hope your son likes this cake as much as we do Valentina 🙂
This looks so good especially with that icing. I think i might make two loaves as well and give one to a friend.
I like how you think Vicky, I hope your friend enjoys it too 🙂
