This oat flour carrot cake is tender, moist, sweet, and full of delicious spices and grated carrot. It's vegan and made without oil, yet perfectly moist and tender thanks to oat flour, applesauce, and a few other key ingredients. Prep is easy, and you'll swoon over the oil-free vegan frosting!
Everyone loves carrot cake, right? The moist texture and the way tangy cream cheese frosting contrasts with the warming spices. It was one of my favorite cakes prior to going vegan, but for some reason I've procrastinated in creating my own recipe.
I think it's because there are so many different ways to approach a vegan carrot cake recipe! So I ran into the whole "paralysis by analysis" thing.
Plus, cakes are special, festive, and usually only make an appearance a few times a year for most people.
That's why I usually prefer decadent, classic-style cakes as opposed to healthier versions. See my vegan birthday cake, vegan strawberry cake, and bourbon spice apple cake as evidence!
But for this carrot cake, I wanted to lean in a healthy-ish direction while still using simple ingredients you can find in any store. Most importantly, it had to taste amazing!
Finally I got there! A vegan carrot cake with oat flour, no oil, and less refined-sugar and flour than most carrot cake, vegan or not!

Why You'll Love It
- Versatile: I tested it in both 8-inch and 9-inch round pans. It really just depends on whether you want thick or thin cake layers and/or the type of pan(s) you have on hand. An 8x8 square pan also works! Divide the ingredient amounts in half to make a single layer cake.
- Game-changing frosting! No butter, cashews, coconut, or oil, yet it's perfectly rich and creamy. Seriously, the frosting really takes the cake up a few notches, so don't skip it!
- Flavor and texture: Replacing oil with non-dairy yogurt and applesauce means this cake is lower in fat and calories than most carrot cakes, while still creating a rich and dense texture.
- Make-ahead friendly: For Easter or other special occasions, you can make the cake in advance and the flavor is even better!
Ingredients
Note that the amounts and full instructions can be found in the recipe card below.
- oat flour - finely ground oat flour creates a tender and rustic texture that's perfect for carrot cake. You can use store-bought oat flour or make it yourself by blending rolled oats in a high-speed blender.
- all purpose flour - during recipe testing I found that the oil-free batter benefitted from the combination of the two flours. Using only oat flour created a crumbly and dense cake. Balancing it with all-purpose flour lightens the cake and helps with binding.
- spices - you'll need ground cinnamon, ginger, cloves and nutmeg.
- baking powder and soda - since our cake is eggless, these serve as our leavening agents.
- plain non-dairy yogurt - this works together with the applesauce to replace the oil usually found in carrot cake. I used cashew yogurt. Other varieties are good, too, like almond yogurt, coconut, or soy yogurt.
- unsweetened applesauce - replacing eggs and oil, applesauce adds moisture and improves the texture. Substitute a neutral oil, if you like, or a combination of the two.
- maple syrup - this also adds moisture, sweetness and flavor that pairs so well with the spices.
- organic cane sugar - Sugar is important for the overall moisture and texture of the cake. Look for organic cane sugar or sugar labeled as vegan to make sure it hasn't been processed using bone char (animal bones).
- lemon juice - acids reacts with the baking soda and help the cakes rise. Feel free to sub 1.5 teaspoons white or apple cider vinegar if needed.
- carrots - I like to grate them by hand using a standard box grater.
How to Make It
Prep is pretty simple! Just be sure to make the frosting in advance.
When you're ready to bake the cakes, line the bottom of the pans with parchment paper, and preheat the oven to 350°F (176°C).
Sift the dry ingredients into a mixing bowl and whisk well. Combine the wet ingredients in a separate bowl, and peel and grate the carrots.
Combine the wet and dry ingredients, and stir just until there's no visible dry flour. Fold in the shredded carrots and chopped nuts, if using.
The batter will be fairly thick and fluffy. Divide it evenly among the pans and gently smooth the surface.
Bake 9-inch cakes for 33 - 35 minutes and 8-inch cakes for 36 - 39 minutes.
They are done when the center lightly bounces back when pressed or a toothpick inserted in the center comes out clean. Cool in the pans for 10 minutes, then flip out onto a cooling rack and remove the parchment.
Once the cakes are cool, place one layer on a serving plate and evenly spread about 1 cup of frosting on top. Place and frost the 2nd layer. If desired, sprinkle chopped nuts on top for decoration. Keep the cake chilled until ready to serve.
Subs and Variations
- gluten-free - A gluten-free flour blend like King Arthur's Measure for Measure should work, but I haven't had a chance to test it yet (getting this one right took so many test batches that we actually need a break from carrot cake–ha). If you try it let us know in the comments below!
- with nuts - Since the frosting is made from almond flour, I usually don't include nuts in the batter, but we do love the texture they add. Chopped pecans or walnuts are perfect. Lightly toast them first for even more nutty flavor.
- raisins or coconut - If you're a fan of raisins or dried coconut in your carrot cakes, feel free to fold these in along with the shredded carrot.

Yield and Pan Size
As written the recipe makes a 2-layer cake. Choose between 8-inch round, 9-inch round, or 8x8 square pans.
- 8-inch round pans produce a cake with extra thick layers like you see in the photos. If using my oil-free frosting recipe, you might have a small amount of frosting leftover. I use Fat Daddio cake pans with 3-inch sides.
- 9-inch round pans and 8-inch square pans hold the same volume and will result in slightly shorter cakes, which is probably better here, in my opinion. Since there is more surface area and the cakes are thinner, these bake a few minutes more quickly, too.
- Divide everything by 2 for a casual, single-layer snack cake.
So it really just depends on what shape/height cake you want and your ideal frosting-to-cake ratio!
For the cakes you'll also need mixing bowls, measuring cups and spoons, and ideally, a kitchen scale for accuracy.
Can I make it in advance?
Absolutely! Once the cakes are completely cool, wrap each layer individually with a double layer of plastic wrap to make sure they stay moist, and refrigerate for up to 2 days.
The frosting can also be made up to 3 days in advance and stored in the refrigerator. This cake holds up beautifully and tastes even better when frosted the day before. Just make sure you have space in the fridge, as it should be kept chilled.
To freeze unfrosted cake layers, after wrapping in plastic wrap place in a freezer bag or other airtight freezer-safe container. Freeze for up to 1 month, then thaw in the refrigerator.
Can I make cupcakes?
Yes, the amount of batter needed for 12 cupcakes is equal to the batter in one 9-inch round cake. So for one dozen cupcakes you can divide the ingredient amounts by 2.
Bake the cupcakes at 350°F for 21 to 24 minutes. Use the toothpick test and lightly press with a finger to determine when they're done.
Top Tips
- Peel the carrots before grating. The outside is bitter so always peel them for the sweetest, best flavor.
- Use a kitchen scale to weigh the flours. If you don't own a scale use the whisk-and-fluff method described in the recipe notes. Otherwise, it's easy to scoop too much flour and end up with a dry cake.
- Sift the flour, spices, baking powder and soda to avoid clumps.
- Work quickly once the wet and dry ingredients have been combined to take advantage of the reaction between the lemon juice and baking soda.
- To test for doneness, lightly press the center of the cakes with a finger. If it bounces back slightly the cakes are done. You can also insert a tooth pick in the center, and if it comes out clean or with a few crumbs, the cakes are done.
- Let the cakes cool completely before frosting.

Instructions
- If using my homemade frosting, prepare it first, preferably the day before, so it has plenty of time to chill.
- Arrange an oven rack so that the cakes will be in the center of the oven and preheat it to 350°F (176°C). Place a circle of parchment paper in the bottom of each pan (no need to oil or flour).
- Sift the dry ingredients into a large mixing bowl, then whisk to combine.
- In a separate bowl, whisk together the wet ingredients.
- Combine wet and dry, and stir just until combined. The batter will be thick and fluffy. Fold in the carrots and chopped nuts, if using. Divide the batter equally among the pans, and use a spatula to smooth the surface. Bake 9-inch cakes for 33-35 minutes and 8-inch cakes for 36-39 minutes.
- The cakes are done when the center lightly bounces back when pressed. A toothpick inserted in the center should come out clean or with a few crumbs. Let the cakes cool in the pans for 10 minutes, then flip out onto a cooling rack and remove the parchment.
- Once the cakes are cool, place one layer on a serving plate and evenly spread about 1 cup of frosting on top. Place and frost the 2nd layer. If desired, sprinkle chopped nuts on top for decoration. Keep the cake refrigerated until ready to serve.

Delicious! I made this last weekend for my birthday. I wrapped and packed the cake layers along with the almond flour frosting and took them out of town with me, where my 9 year old granddaughter frosted and decorated the cake . I reduced the sugar in the cake (1/3 c. sugar and 1/3 c. erythritol). Everyone loved the cake. The frosting was a little thick, maybe next time I'll add a little more soy milk. Thanks for all your wonderful recipes.

Do you have the measurements to weigh the flours for this recipe?
Lori Rasmussen says
Hi Susan - Yes, if you tap on "Metric" above the ingredients it will display the weight in grams.
Susan L. says
Any substitutions for the yogurt? I have all the ingredients at home to make this...but not the yogurt... 🙃
Lori Rasmussen says
Unfortunately, not that I've tested, so it would really just be a guess. You need something that contains some fat and not much liquid, like nut butter mixed with some mashed banana or additional applesauce, plus a little bit of non-dairy milk, maybe? I would hate for it to not work out for you. Definitely try a single layer if you do! 😀
