Gluten-Free Lemon Layer Cake
This gluten-free lemon layer cake uses three naturally gluten-free flours to create a velvety crumb that’s balanced by lots of bright lemon zest. Layer it with sweet strawberry jam and vanilla buttercream for a super special cake.
Oooh, sometimes you make a cake and it is just perfect. A lemon cake is one of my favorites to put together (I am working on adapting my favorite, simple lemon yogurt cake to be gluten-free) and it is just right for spring. This recipe for the loveliest of lemon layer cakes that I’m sharing today is one of those “perfect cakes.”
This particular lemon-kissed cake would would be a wonderful ending to any holiday meal, or as a dessert for any spring gathering. Just three gluten-free flours in combination create a velvety texture that is balanced by lots of lemon zest.
Luscious lemon layers are filled with strawberry jam and a little lemon buttercream and the whole cake is covered in the lemon-spiked frosting. I topped mine with blueberries but you could certainly do fresh strawberries or raspberries as you like. This is definitely a more “fancy” cake than what I usually do, which makes it a special occasion treat, and so worth it!

Make Cake

- Rest batter. Divide the batter evenly between the two pans and let rest for 10 minutes.
- Bake cake. Place the cake in the oven and bake for about 30-35 minutes. Let cool completely.
Make Frosting
- Make frosting. Beat the butter, powdered sugar, lemon juice, and zest together. Add milk and mix until desired consistency.
Assemble
- Fill cake. Place one cake layer on a plate. Spread a very thin layer of buttercream on the layer, then top with the strawberry jam
- Frost cake. Top with the other cake layer. Frost the top and sides of the cake with the remaining buttercream.
Substitutions
Sorghum flour – swap in oat flour.
Sweet white rice flour – try almond flour.
Tapioca flour – use arrowroot.
To make dairy-free – use coconut oil in place of the butter and a non-dairy milk of choice.
To make refined sugar-free – Sub maple sugar for the sugar, and homemade powdered sugar for the powdered sugar.
Storage
Cake may be stored, well-covered in the fridge, for 3 days. Bring to room temperature to serve for the best texture and flavor.

For Frosting
- ¾ cup unsalted butter
- 1 ½ cups powdered sugar
- 2 tsp fresh lemon juice
- 1 organic lemon, zested
- 1-2 tbsp whole milk
Instructions
Make Cake
- Butter 2 8-inch cake pans and line with parchment paper.
- In a medium bowl, whisk together the flours, baking powder, and salt.
- In a large bowl, place the sugar and lemon zest. Using your hands, rub the lemon zest into the sugar for a minute or so until fragrant to release the lemon oil.
- Add the butter to the bowl with the sugar and lemon zest. Using a stand or handheld mixer, cream the butter into the sugar-zest mixture, beating on high speed for about 3 minutes until smooth and creamy. Beat in the eggs one at a time, scraping down the bowl as necessary. Beat in the vanilla until well combined.
- Add the flour mixture in three additions with the milk: flours, milk, flours, milk, and finish with the flours. Mix well on medium speed to make sure all the flours are incorporated.
- Divide the batter evenly between the two pans. Cover and let rest for 10 minutes, then preheat oven to 350° F. Let cake batter continue to rest until oven is ready.
- Place the cake in the oven and bake for about 30-35 minutes, checking at 25 minutes, until a tester inserted in the middle comes out clean. Remove from oven and place on a wire rack; let cake cool in pans for 10 minutes, then turn out onto the rack to cool completely.
Make Frosting
- With a handheld or stand mixer, beat the butter on medium speed until creamy, about 2 minutes. Add powdered sugar, lemon juice, and zest with the mixer running on low. Add the milk. Increase mixer speed to high speed and beat for 3 minutes until light and fluffy. If you think you need it, add a bit more sugar or milk for desired consistency.
Assemble Cake
- Place one cake layer on a plate. Spread a very thin layer of buttercream on the layer, then top with the strawberry jam. I went light on the jam, but you could increase it as you wish.
- Top with the other cake layer. Frost the top and sides of the cake with the remaining buttercream.
- Store the cake, well-covered, in the fridge, but serve at room temperature for best texture and flavor. Cake will keep in the fridge for 5 days.
