An incredible gluten free lemon cake! Layers of delicious lemon cake, filled with fresh lemon curd, and frosted with a lemon curd buttercream frosting.
Happy Fall!
I can’t believe it’s already October. It’s been quite a while since I’ve posted a recipe here on the blog. I’ve been active on Instagram, but let’s just say I baked a little too much during quarantine this spring and summer… I needed a little break.
I’m excited to be back and finally show you the recipe for this ultimate Gluten Free Lemon Cake with Lemon Filling!
I have made this cake quite a few times this summer as it quickly became a family favorite. I know right now you may be into all things pumpkin and apple, but this cake is so good it deserves a spot in your home any time of year.
Let’s talk about it for a second…
This gluten free lemon cake It’s filled with fresh lemon curd filling and frosted with a delicious lemon curd buttercream. The cake itself is perfectly moist and spongy with a lovely sweet lemon flavor.
I prefer to make my own fresh lemon curd filling for cakes, but you can always use store-bought as a shortcut.
Finally, it’s frosted with a lemon frosting. I put lemon curd in my buttercream instead of lemon juice because it really enhances the lemon flavor!
All this lemon makes for a wonderfully sweet, and not too tart, lemon flavor carried throughout the cake.
WHAT FLOUR TO USE FOR GLUTEN FREE LEMON CAKE
For all my cupcake and cake recipes, I use Bob’s Red Mill 1:1 gluten free baking flour. This is the flour that I have been using since my Celiac diagnosis and seems to work the best for me! Not all gluten free flour mixes absorb moisture the same way, and they all have different proportions of ingredients used, so keep in mind that this recipe was designed specifically for this flour mix.
I always measure my flour by weight to ensure I’m using the exact amount needed, as even just a little bit more or less could change the texture of the cake. It’s also nice because I don’t have to dirty as many measuring cups, so I just spoon my flour into a bowl on my kitchen scale to weigh. If you don’t have a kitchen scale, you can measure your flour by spooning it into your measuring cup and then leveling it off before adding it to your dry ingredient bowl. This helps to prevent you from using too much flour, which can happen when you scoop it out of the bag with your measuring cup.
I haven’t tested this recipe with other flours, so I can’t guarantee that your cake will turn out the same if using a different flour mixture. If using a different gluten free flour mixture, I recommend using a 1:1 mix that contains xanthan gum and measure by weight. I have seen some bakers make my recipes successfully with Pillsbury gluten free flour. If you made this successfully with a different flour, please let me know!
CAN I MAKE A 4 LAYER CAKE
Yes!! I have made this into a 4 layer cake and it’s just as perfect. Just fill 2 cake pans instead of 3 and bake for around 40 minutes until a toothpick inserted in the center comes out clean. Once the cakes have cooled completely (I find it’s best to have them chill in the refrigerator for at least an hour first… more on chilling below), cut them in half lengthwise across the middle with a serrated knife so that each layer becomes two. You will now have 4 thinner layers.
There is still enough frosting and filling in this recipe for a 4 layer cake.
CAN I MAKE OTHER SUBSTITUTIONS?
Gluten free baking is very finicky. I don’t recommend making a lot of substitutions as this it can really change the structure and texture of the cake.
However, there are a few that I have personally done that work well:
Dairy: For the yogurt, I usually use plain low-fat yogurt. You can use a dairy free yogurt or swap it for sour cream if you need to. I don’t recommend using greek yogurt as it’s had most of the liquid strained out and might make the cake a little dry or give it a different texture. For the milk, you can use regular cows milk or a non-dairy version. Canned coconut milk is too thick and has a different fat content and will not work well (I have tried it).
Oil: You can use any neutral oil you’d like in this gluten free lemon cake cake recipe. Melted or liquid coconut oil will also work, however depending on what type you use it may give the cake a coconut flavor.
Lastly, I did make this cake using myer lemons once instead of regular lemons. It was just as delicious! Keep in mind you may need more myer lemons because of the smaller size.
HOW TO STORE GLUTEN FREE CAKES
One thing I’ve found really helps with the texture of gluten free cakes is to refrigerate them before and after frosting. This cake is still great without refrigerating, but it’s even better when chilled as refrigerating helps to lock in the moisture and keep the cake from drying out.
Once the cakes have baked and cooled for about 10-15 minutes, carefully remove them from the pans and place on a wire cooling rack lined with parchment paper to cool completely.
After they have cooled completely, place the cakes on a large parchment-lined baking sheet, cover with a piece of parchment (to help prevent the cake tops from sticking) and cover tightly with foil. Then, place the baking sheet into the refrigerator until to chill at least one hour. You could also do this step the night before and keep the cakes chilled overnight. This not only helps to keep the cakes very moist but also makes it much easier to stack and frost.
Once you have filled and frosted the whole cake (the frosting for this cake recipe makes enough to fill, cover, and decorate a 6” cake), you could either eat it immediately or store it in the fridge for later. My cake recipes all work well for making a full day ahead of time. Just cover the assembled and frosted cake either with a glass cake dome or in an airtight cake container/carrier, then place it back into the refrigerator – just bring it out at room temperature 15-20 minutes before you are ready to serve.
6” stacked cakes are usually anywhere between 6-8” tall (or taller depending on if/how you decorate the top of the cake), so make sure your cake dome is large enough. If you don’t have a cake dome or airtight cake storage container, you can also place the cake on a large plate and cover it with a large stockpot if it fits in your fridge! The cake just needs something over it to prevent air from getting in and drying out the cake, as gluten free cakes tend to dry out quickly.
Store any cake leftovers in the refrigerator under the cake dome, or you can pre-slice and store in airtight containers. The cake should stay fresh this way for 3-4 days before it starts to dry out.
I hope you love this lemon cake as much as my family and I do! If you make it, be sure to comment below, or tag @zestandlemons on Instagram.
Gluten Free Lemon Cake with Lemon Filling
An incredible gluten free lemon cake! Layers of delicious lemon cake, filled with fresh lemon curd, and frosted with a lemon curd buttercream frosting. Makes one 3 layer 6-inch cake
Ingredients
For the Cake
- 1 ¾ cup (250g) Bob’s Red Mill 1:1 Gluten Free Baking Flour
- 2 tsp baking powder
- ½ tsp salt
- Zest of two lemons
- ⅔ cup oil (neutral oil)
- 1 ¼ cup granulated sugar
- 3 eggs
- ⅓ cup plain yogurt
- ¼ cup milk
- ¼ cup fresh lemon juice
Lemon Curd Filling
- 1 recipe for fresh lemon curd filling
Lemon Frosting
- 1 ¼ cup unsalted butter, room temperature
- 4 cups powdered sugar, more if needed
- 3-4 Tbsp lemon curd
- ¼ tsp vanilla extract
- 1-2 Tbsp milk or heavy cream, more as needed
Instructions
Lemon Curd
- Make one recipe for lemon curd filling at least a few hours before starting the cake so it has time to chill, or use store-bought lemon curd. You will need about ½ cup or more to fill a three layer cake, and up to ¼ cup for the frosting.
Make the Cakes
- Preheat the oven to 350℉. Grease and flour three 6” round cake pans and line the bottoms with a circle of parchment paper. Set aside.
- In a large mixing bowl, whisk together flour, baking powder, salt, and lemon zest. I like to whisk several times at a faster speed to aerate the flour a bit (this will help create a slightly lighter cake). Set aside.
- In a medium mixing bowl, whisk together oil, granulated sugar, eggs, yogurt, milk, and lemon juice until combined.
- Pour the wet ingredients into the dry ingredients, slowly mixing together until smooth and combined.
- Evenly divide the batter between the cake pans, there should be about 1 ¼ cups of batter in each. I prefer to weigh mine so the layers are always even!
- Bake for 30-35 minutes just until a toothpick inserted in the center comes out clean. Remove from the oven and let cool for about 10 minutes before carefully turning out onto a parchment-lined cooling rack. Allow to cool completely.
- Although not a necessary step, the cakes are more moist and stack easier if you refrigerate them after cooling. Please read the notes/blog post above about chilling the cake and how to store!
Make the Frosting
- Add the butter in the bowl of a stand mixer fitted with the paddle attachment (you can also use a large bowl and a hand mixer), and beat on medium-high speed until pale and fluffy, about 5-7 minutes. You may need to scrape down the sides of the bowl a few times in between.
- With your mixer running on low speed, add in the powdered sugar ½ cup at a time until combined, stopping to scrape down the sides of the bowl as needed.
- Add the lemon curd, vanilla, and 1 Tbsp of milk or heavy cream. Beat on medium-low speed (I use speed 4 on my Kitchenaid mixer) for 1-2 minutes until the frosting is light and fluffy. If your frosting is too thick, slowly mix in additional heavy cream or lemon curd as needed. If too thin, add more powdered sugar.
Assemble:
- Place the first layer of cake on a cake stand or serving plate. Pipe a thick frosting border or dam around the top outside edge of the cake. Fill with about ¼-⅓ cup of lemon curd, just so the filling almost reaches the top of the border. Top with the next layer of cake and repeat. Here’s a great video to watch on how this is done: https://www.youtube.com/watch?v=h3Rw065BZbg.
- When you top with the final cake layer, finish by carefully spreading the remaining frosting evenly on top and around the cake and decorating how you’d like!
- Serve immediately, or store in the refrigerator under a cake dome or airtight cake container until 15-20 minutes before you’re ready to serve.
Notes
Before Baking: I always line the bottom of my cake pans with a circle of parchment paper. If you’re having trouble getting the parchment to lay flat in the pan, crinkle it up into a ball with your hands first. When you open it back up, it should lay pretty flat.
Flour: I used Bob’s Red Mill 1:1 gluten free baking flour for this recipe, which already contains xanthan gum, so I cannot guarantee that your cake will turn out the same if using a different flour mixture. Not all gluten free flour mixes absorb moisture the same way, and they all have different proportions of ingredients used. If using a gluten free all purpose flour mix, I recommend using a 1:1 mix that contains xanthan gum and measure by weight. Always spoon and level your flour into your measuring cups! Scooping out your flour with the measuring cup can lead to using too much.
Storing: Please read the blog post above regarding refrigerating the cakes before and after frosting. You can make this cake up to one full day ahead of time and store in in the refrigerator in an airtight cake container or under a cake dome. Refrigerate any leftovers under the cake dome, or pre-sliced in airtight containers. The cake should stay fresh for 3-4 days this way before drying out.
Hi,I made this cake for an elderly lady on Mothers day & she absolutely loved it.,I too tried it & was very happy with the results,definitely my goto cake in the future.
Thank you so much for making the recipe and I’m so happy to hear you loved it!
Have you had any problems with doubling or tripling this recipe? I need to make a gluten free wedding cake and need bigger than 6″ rounds. Also, in your directions #3 says to stir in the expresso powder – I’m assuming this is for a different recipe but just thought I’d let you know.
Hi Lori, thanks for catching that mistake! It’s all fixed. And I haven’t personally tried doubling or tripling any of my cake recipes, so I don’t have any specific tips to provide and don’t know if it will turn out the exact same. However, I have made some of my cakes in two 8″ rounds instead of three 6″ and they turned out great (you just may need to adjust the baking time a bit). Depending on how many layers you are doing, I’d personally just make the recipe two or three times separately to be safe. Let me know how it turns out if you try it!
I’ve been wanting to try a recipe for gluten free cupcakes and just found your cake recipe and it sounds delicious. I’ll let you know how it works as cupcakes!
Looks delicious! How well does this frosting pipe? I am looking to do some serious piping decoration and want to know if this frosting can do the job 🙂
Hi! I have made this cake several times with awesome success. I’m wondering if you have the recipe for the yellow drizzle that you use on the outside of the cake
Hi! So happy you love the recipe, it’s one of my all-time favorites. Thank you for making it so many times! The drip on top is my lemon curd recipes (also on the blog) and I just added a few drops of water to make it drip better.
