Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

3 eggs (room temperature)
1 3/4 cup fine granulated cane sugar
2/3 cup oil (any neutral oil)
1 3/4 cup milk (dairy or non-dairy)
1 tablespoon vanilla extract
4 tablespoons fresh lemon juice
1 teaspoon lemon extract
1 to 2 tablespoons lemon zest (about 1 large lemon)
2 3/4 cup gluten free all purpose baking flour
1 cup fine blanched almond flour
1 teaspoon baking soda
1 1/2 teaspoon baking powder
1/2 teaspoon salt

For the buttercream:
3/4 cup butter (room temperature)
2 tablespoons lemon juice
3 tablespoons milk (dairy or non-dairy)
1 tablespoon lemon zest (or to taste)
4 cups powdered sugar

Directions

Preheat the oven to 350 degrees Fahrenheit.

Prepare your baking pan by lining the bottom with parchment paper. Lightly oil the bottom first so the parchment sticks easily. Use one 9×13 pan, two 9-inch round pans, or three 6-inch round pans.

In a large bowl or stand mixer, beat together all the wet ingredients until well combined.

Add the dry ingredients, making sure to spoon and level the flours instead of scooping directly from the bag.

Whisk the mixture until just combined. The batter should be smooth and slightly thin, similar to pancake batter. Avoid over-mixing.

Pour the batter into the prepared pan(s) and place in the oven. Bake times will vary depending on pan size.

Check for doneness with a toothpick. The cake should be golden on top and set in the center.

Remove from the oven and let cool for about 10 minutes. Carefully transfer to a cooling rack and remove the parchment paper, or leave in the pan if making a sheet cake.

Allow the cake to cool completely. For best results, chill it in the fridge for about an hour before frosting.

To make the buttercream, beat the room temperature butter until smooth.

Gradually add the powdered sugar, about one cup at a time, until the desired consistency is reached.

Mix in the milk, lemon juice, and lemon zest until smooth and creamy.

Frost the cooled cake and serve.

Variations

Add fresh berries like blueberries or raspberries to the batter for a fruity twist.

Use a lemon glaze instead of buttercream for a lighter finish.

Turn this into cupcakes by dividing the batter into lined muffin tins and reducing the baking time.

Add poppy seeds for a lemon poppy seed version with a slight crunch.

For a dairy-free version, use plant-based butter and milk alternatives.

Storage/Reheating

Store the cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days.

If refrigerated, allow slices to come to room temperature before serving for the best texture.

You can freeze the unfrosted cake layers for up to 2 months. Wrap tightly and thaw before frosting.

FAQs

Can I use a different gluten free flour blend?

Yes, but results may vary. A 1:1 baking blend works best for maintaining texture.

Why is almond flour included?

It adds moisture and a tender crumb, helping prevent the cake from becoming dry.

Can I make this cake dairy-free?

Yes, simply use non-dairy milk and a plant-based butter substitute.

How do I know when the cake is done?

Insert a toothpick into the center. If it comes out clean, the cake is ready.

Can I skip the lemon extract?

Yes, but the flavor will be less intense. You can increase the zest slightly to compensate.

Why is my cake dense?

Over-mixing or incorrect flour measurement can lead to a dense texture.

Can I make this ahead of time?

Yes, you can bake the cake layers a day in advance and frost before serving.

What oil works best?

Any neutral oil like vegetable, canola, or sunflower oil works well.

Can I reduce the sugar?

You can slightly reduce it, but it may affect the texture and moisture.

How do I get a stronger lemon flavor?

Add extra lemon zest or a bit more lemon extract for a more vibrant taste.

This gluten free lemon cake is a bright, flavorful dessert that combines a soft, tender crumb with a rich citrus frosting. It’s easy to customize, simple to prepare, and perfect for any occasion where you want a fresh and satisfying homemade treat.
