Gluten Free Lemon Cake
This gluten free lemon cake is moist, spongey and so easy to make. Just one bowl and a few simple ingredients. Top it off with a sweet and tangy dairy free lemon buttercream frosting.

This cake has been a long time coming and gone through SO many phases! I initially planned on making a vegan lemon cake that would of course be gluten free, but every trial results in a gummy, weirdly chewy or really dense cake.
After about 5 tries, I decided to throw in the towel on the vegan idea and just stick to a really, really good gluten free lemon cake. The eggs provide this cake with structure and help contribute to the perfect spongey texture.
This cake also uses a mix of gluten free all purpose flour and almond flour to provide a nice cakey texture. It’s much fluffier than my gluten free lemon drizzle cake, which is more like a pound cake.
I sometimes find that just using the all purpose flour can yield a slightly gummy texture, but a little bit of almond flour really helps to balance that all out and keep the cake light, fluffy, moist and delicious.
One bite into this cake and you’re going to fall in love. It’s the perfect Easter dessert, but to be honest, I would eat this any day or any time of year. If you love this recipe, my strawberry cake, almond flour vanilla cake or orange cake next!

How to make gluten free lemon cake
Line either one 9×13 pan or two 9 inch round pans or three 6 inch round pans with parchment paper just on the bottom. It helps to lightly oil the bottom then put the prepared parchment paper in so it sticks easily. Set aside.
In a large bowl or bowl of a stand mixer, beat together all wet ingredients until well incorporated. Use a handheld electric mixer if not using a stand mixer.
Add in the dry ingredients, making sure to spoon and level the flours to measure, don’t scoop from the bag. Use a whisk to mix together until well combined, but careful not to over-mix.
It shouldn’t be runny, but definitely won’t be thick either. It should resemble a fairly thin pancake batter.
Pour into your prepared pan(s) and add to the oven. The 9×13 will take about 32-40 minutes, the 9 inch will take closer to 25-30 and the 6 inch will take about 45. Check with a toothpick to test doneness.

Remove from the oven, let cool for about 10 minutes, then carefully flip onto a cooling rack and peel off the parchment paper. If you’re making a sheet cake, you are welcome to leave it right in there and frost it in the pan for easy storage.
Let cool completely before frosting. I suggest sticking in the fridge for about an hour to ensure it’s fully cool.
To make the buttercream, add the room temperature butter, milk lemon juice an zest to the bowl of a stand mixer or large mixing bowl and beat until well combined. I prefer using a stand mixer to make buttercream.
Beat in the powdered sugar, 1 cup at a time until your desired consistency is reached. I used about 4 cups for this recipe. To make it thicker, add more sugar, to make it thinner, add more milk. Frost the cake once cool & enjoy! Try my lemon pistachio cake next!
WANT TO SAVE THIS RECIPE?

Getting the perfect flavor
This cake uses three forms of lemon to achieve the perfect lemon flavor. We’ll be using fresh lemon juice, zest and lemon extract. That might seem like a lot, but I promise it’s SO good! Same with in my lemon brownies!
The tangy of the lemon gets balanced by the sweetness from the sugar and the richness from the oil. Lemon juice and lemon extract are not the same, so be sure you’re using both in this recipe!
I also don’t recommend bottled lemon juice as it will react differently with the baking soda compared to fresh lemon juice.

The best flour for gluten free cake
If you’ve made any of my recipes before, you know I’m very loyal to my Bob’s Red Mill 1:1 Baking flour. A lot of gluten free bakers prefer making their own blends, but I find it easiest for me and you to use a blend. Plus, if you’re not gluten free, just swap it out for regular all purpose flour.
I highly recommend sticking to the Bob’s flour since there is a lot of variation brand to brand, but if you opt to use a different one, just make sure it has xanthan gum in the mix!
This gluten free cake truly tastes no different than a regular cake. I’m the only one in my family who is gluten free and everyone says it tastes just like the real deal. Try it (and then my gluten free lemon cupcakes) and you’ll see!

How to keep cake moist
For whatever reason, a lot of people seem to think gluten free cakes (like my mint chocolate cake) and other baked goods are really dry. Because of that, I make a serious effort to ensure all of my recipes are incredibly moist and stay that way.
This gluten free lemon cake is made moist with the oil, milk, eggs, a generous amount of lemon juice and even almond flour. As long as you store it in a container or wrapped with foil, you should have no problem keeping this cake moist!
I even find that it can get more moist as it sits because the buttercream seeps into the sponge a bit overtime. I promise, no dry cakes over here, even with my dairy free birthday cake.
Once prepared, this cake will keep for about 3 days at room temperature or 5 in the fridge.

Lemon Buttercream
- ¾ cup butter room temperature
- 2 tablespoons lemon juice
- 3 tablespoons milk dairy or non-dairy
- 1 tablespoons lemon zest or to taste
- 4 cups powdered sugar
Instructions
- Preheat the oven to 350 degrees Fahrenheit.
- Line either one 9×13 pan or two 9 inch round pans or three 6 inch round pans with parchment paper just on the bottom. It helps to lightly oil the bottom then put the prepared parchment paper in so it sticks easily. Set aside.
- In a large bowl or bowl of a stand mixer, beat together all wet ingredients until well incorporated. Use a handheld electric mixer if not using a stand mixer.

- Use a whisk to mix together until well combined, but careful not to over-mix. It shouldn’t be runny, but definitely won’t be thick either. It should resemble a fairly thin pancake batter.
- Pour into your prepared pan(s) and add to the oven. The 9×13 will take about 32-40 minutes (mine took 35), the 9 inch will take closer to 25-30 and the 6 inch about 45 (they’re smaller but the layers will be fairly thick so they need to bake for longer).
- Check with a toothpick to test doneness. The top should be golden brown and there should be no jiggling on the inside.

- To make the buttercream, add the room temperature butter to the bowl of a stand mixer or large mixing bowl and beat until well combined. I like using a stand mixer for buttercream, but a hand mixer will work!
- Beat in the sifted powdered sugar, 1 cup at a time until your desired consistency is reached. I used about 4 cups for this recipe. To make it thicker, add more sugar, to make it thinner, add more milk. Beat in the milk, lemon juice and zest until well combined.

I can’t wait to try this for a client of mine! I will sub out almond flour due to an allergy but she really wants a hint of maple syrup. Where could I sub this? She also can’t have cane sugar, but I have a few sugar substitutes here. Any ideas? Thanks! I will update you on the finished product!
-
I would probably suggest decreasing how much of the sugar sub you use, and then swapping some of the milk for maple syrup- maybe 1/4-1/3 cup. Let me know if you try it!

This cake was awesome! I changed it up a bit and added 1/2 c sour cream with 1 1/4 c almond milk. Also threw in about 1/3 c slivered almonds as well as coconut. Then the icing I did 3 3/4 c sugar but even that was too sweet. Also speinkedl coconut on top. Next time I will do less sugar and toast the coconut. It was a huge hit with everyone at family dinner taking seconds!!
-
Yum! So glad it was a hit!
-
-
I have a question
When I click on Metric it says 1 1/2 butter but 1 and a half what???-
Sorry about that, should be fixed now!

I made this for my boyfriend’s birthday, and it was a hit! We are all gluten free, and we were delighted with how moist this cake was. I used coconut milk for the cake, but for the frosting I used whole milk. I am a huge lemon lover, so I am a big fan of this one. Thanks for the awesome recipe!
-
Hello, Can I use 2 x 8 inch pans instead? How long should I bake for? Thanks!
-
Yes, probably around 35-45 minutes.
-
-
I loved this cake!! I made it for myself for my b-day, and what a treat it was! Slight mods were – I spread a very thin layer of raspberry jam between the 2 layers of cake. And I used a good quality store-bought coconut-oil-based vanilla frosting instead of making this frosting. My non-GF friends had nothing but praise for the cake. Thank you for a delicious recipe and for making my day (b-day)!!
-
Love the idea of adding raspberry jam! Sounds amazing.
-
-
How long would you beat the dry into the wet ingredients and what speed
-
Just until combined on medium/low speed.
-
-
I made the cake in a 9 / 13 Pan. The edges were baked well and delicious but was still quite dense and raw in the middle even though a toothpick came out clean after 41 minutes in the oven. Do you have any suggestions?
-
All ovens are different, so I would just increase the bake time next time!
-
-
Hi if I use a gluten free flour without xanthan gum how much would I need to add.
-
I would add about 1 1/4 teaspoons.
-
-
A+for texture. It doesn’t easily dry out and freezes well. I made mine with raspberry buttercream and overall very good, but could definitely use more lemon flavor. I might add some extract next time.
-
Can you substitute granulated sugar for the cane sugar?
-
Yes, same thing!
-
-
Easily the best GF cake I’ve made to date. Moist, sturdy enough to stack, simple!
-
Thank you, Kate!
-
-
Delicious!
Have you frozen the cake before to put together with the icing a few weeks later?
-
Yes! You can freeze for up to 1 month and frost when you’re ready to serve.
-
-
This recipe is perfect as is! I followed it to the letter and then uses Lemon Cream Cheese Frosting. Everyone raved and you can’t tell it’s gluten free. I added a little more lemon zest only because I like a zing.
-
Love a lemon cream cheese frosting! So glad you enjoyed it!
-
-
Excellent, excellent excellent! I would have given a rating of 10 if I could. I followed the recipe exactly and it turned out amazing. The cake is moist and delicious. The texture is perfect. I used three 8-pans and baked for 25 min. I will make this again for an upcoming engagement party.
-
Amazing! Honored to have it at an engagement party 🙂
