This lemon sheet cake is incredibly soft, moist, and very delicious, even though it’s completely oil-free! The recipe is vegan, gluten-free, refined sugar-free, and very easy to make. Watch the video below to see the simple instruction steps.
Healthy Lemon Sheet Cake
I don’t know where to begin, because this vegan lemon cake recipe actually left me speechless! It’s oil-free, vegan, gluten-free, refined sugar-free, yet it turned out moist, soft, and very flavorful. I really didn’t expect it to be that good.
If you check out other lemon cake recipes, almost all of them contain lots of eggs, butter, regular flour, and tons of sugar. But not this lemon sheet cake. It’s quite healthy and the taste doesn’t disappoint.
11 Simple Ingredients
Maybe you already have most (or all) of the ingredients at home. If not, they should be easily accessible in all supermarkets. The 11 ingredients are:
- Rice flour
- Oat flour (ground oats)
- Liquid sweetener of choice
- Canned coconut milk
- Powdered Erythritol (or powdered sugar)
- Baking powder
- Baking soda
- Lemon juice + zest
I used white rice flour, however, this easy lemon sheet cake might also turn out great with brown rice flour. Also, I always make my own oat flour by simply processing oats in a blender or in an electric spice/coffee grinder. It takes only 20 seconds and saves a lot of money! You can use regular oats or certified gluten-free oats.
Maple syrup, rice malt syrup, Yukon syrup or agave syrup are just some examples of liquid sweeteners which can be used in this recipe.
I prefer using canned coconut milk because it’s rich, and adds a nice flavor. However, if you are a coconut hater, I would suggest using any other plant-based milk and adding 2 tbsp of oil. Why? Because the recipe is completely oil-free and relatively low in fat. Boxed plant-based milk is basically just water, and I am afraid the cake might end up too dry if you use it without oil!
Powdered Erythritol makes the best icing, in my opinion (and I tried many). Furthermore, it’s refined sugar-free and has zero calories (which isn’t important to me, however, I prefer not to use refined sugar). You can use powdered sugar though if you don’t have access to Erythritol.
Turmeric adds a nice yellow color and since we are only using 1/8-1/4 tsp the taste isn’t noticeable in the finished vegan lemon cake.
I am sure the other ingredients (baking powder, baking soda, lemon, salt) don’t require an explanation. 🙂

Dry Cake Ingredients
Wet Cake Ingredients
- I recommend using a kitchen scale for this recipe.
- Preheat oven to 350 degrees Fahrenheit (180 degrees Celsius) and line a baking pan (or sheet pan) with parchment paper with an overhang for easy removal. My pan measures 9"x6" resp. 23x15 cm (see pictures above in the blog post).
- Mix all dry ingredients in a bowl with a whisk.
- Add the wet ingredients and mix with a whisk until combined (don't over mix).
- Pour the batter into the lined pan. Bake for about 25 minutes in the oven or until a toothpick (inserted to the center) comes out clean. It took 24 minutes in my gas oven.
- Let cool completely. Meanwhile, make the icing/glaze.
- Simply add all ingredients to a small bowl and mix with a whisk. The icing should be runny but not too thin. If it's too thin, add more powdered Erythritol/powdered sugar. If it's too thick add a little more lemon juice or plant-based milk.
- Pour the icing onto the cooled lemon cake and put the cake in the fridge for about 20-30. The icing will firm up pretty quickly when you use Erythritol (what I did).
- Cut into squares and enjoy! Store leftovers in the fridge for up to 5 days. Check the recipe notes below.
