Simple Oat Flour Carrot Cake – Gluten-Free Recipe You Need!
Miss the taste of a moist vintage carrot cake? Then here’s a recipe to save, print, make, and repeat often. One bite of this fluffy treat and you will understand why this has quickly become a favorite in my all-star gluten-free cakescollection. Then you will be equally floored it’s made with oat flour. 🤯
If you’re a little thrown by with baking with oat flour, let me break it down. Oatmeal. We’re all familiar with that, right? I bet you even have some oats right in your pantry. Just like this magical 5-minute homemade oatmeal bread, this carrot cake starts and ends with a quick whiz in the blender.
Now we’re talking. An oat flour carrot cake recipe all made in a blender?! Yep, it’s as easy as that. But no sweat if you don’t have something on hand to pulverize those oats into flour. Also included is an easy how-to for making the cake without a blender.
Once you have the oats blended into flour, just mix in all that classic carrot cake goodness – hand-grated carrots, warm inviting spices, the perfect leavening and moisture for a fluffy, yet moist crumb. Then, smother on a gooey, thick layer of browned butter cream cheese frosting on top. If cream cheese isn’t your jam, then try the world’s fluffiest buttercream, vanilla glaze, or let the cake do all the talking and simply dust with powdered sugar.
Once you fall in love with this recipe (guaranteed, you will!), I have another goodie – uber fluffy chocolate oat cake. So, so good!

Let’s Make This Together!
(Below shows step-by-step photos and modified instructions. For the complete recipe, along with ingredient amounts, scroll down to the recipe card.)
Blend up the oat flour.
If you have a high-speed blender, like a Vitamix, first dump the oatmeal in and process into a fine, powder. You also have the option to make with ready-made oatmeal flour and mix the batter by hand. Those instructions are in the recipe card below. 👇

Dump and mix other yummy carrot cake stuff.
Now you get to see why this recipe is so miraculous. Just add in the remaining cake ingredients and blend. Start with the remaining dry ingredients and combine. Add in the applesauce for added moisture, eggs, milk (dairy-free is fine), vanilla, and a little oil to further soften the crumb.
Once that’s nice and smooth, dump in the grated carrots, raisins, and optional nuts. I just pulse a couple times to mix in or you can stir it in the blender with a wooden spoon.

Time to bake.
If you’d like to lift the cake out of the pan to transfer to a platter, line your baking dish with parchment to lift out. Otherwise, pour the batter into a greased 8X8-inch baking pan or check out the alternative cake pan options.
Bake for 30-35 minutes, or until a toothpick comes out clean and the top slightly cracks. Cool completely before swirling on frosting.

Browned butter cream cheese frosting?! Yep, it’s as good as it sounds.
When making browned butter, it’s best to start with room temp, slightly softened butter. After it melts, stir occasionally so it doesn’t burn. It will foam, then the milk solids will start to settle at the bottom. Once the milk solids go from white to brown, it’s ready. Immediately transfer it to a mixing bowl to cool.
Add in the softened cream cheese, powdered sugar, and cream. Beat into fluffy clouds of sweetness. Try not to eat it all before it gets on the cake. Seriously.


Why Hand-Grated Carrots Work Best For Cake
Okay, I’ve been touting how easy it is to make carrot cake with oat flour, but I guess I left out one teeny asterisk…You have to grate the carrots by hand.
Why? Those pre-grated carrots from the store are dry and devoid of the moisture you will need. Your other option would be to use the grater disc on a food processor. My hesitation with this is it possibly creating too much moisture, throwing off the balance of the cake. If you try it this way, will you do me a solid and leave me a comment below?
Layer Cake and Alternative Baking Pan Options
I really contemplated if I should make this a layer or single layer recipe. I anguished over it. Eventually single layer won out because I wanted the recipe to be easy and approachable.
However, there would be zero issue turning this into a layer cake. Just double the recipe and divide the batter between two greased 9-inch cake pans. The baking time would stay the same. You would also need to double the frosting ingredients.
If you’d like a single round layer, pour the batter into a 9-inch round pan. A 9X9 or 11X7-inch pan also works, but the cake will be slightly thinner and the baking time would decrease by about 5 minutes.

Equipment
Instructions
- Preheat the oven to 350ºF. Grease 8X8 inch pan or 9-inch round cake pan with nonstick cooking spray. Line with parchment and overhang, if lifting out. Set aside.
- Hand grate and measure carrots so they can be added to the mixture when ready. If the batter sits while the carrots are grated it could absorb too much moisture and become dry.1 cups grated carrots
- Blender Method – Place the rolled oats in a powerful high speed blender, such as a Vitamix. Process into a fine, powdery flour, about 30-60 seconds. Add the remaining dry ingredients – granulated sugar, brown sugar, cornstarch, baking powder, baking soda, spices, and salt. Pulse to combine. Hand Mixer Method – Add the oat flour and remaining dry ingredients to a large bowl. Mix together on low speed.2 cups gluten-free certified rolled oats, ½ cup granulated sugar, ¼ cup packed light brown sugar, 3 tablespoons cornstarch, 1½ teaspoons baking powder, ½ teaspoon baking soda, 1 teaspoon ground cinnamon, ¼ teaspoon ground cloves, ¼ teaspoon ground ginger, ¼ teaspoon ground nutmeg, ¼ teaspoon salt
- Blender Method – Add the wet ingredients – eggs, milk, applesauce, oil, and vanilla. Process again to combine, scraping down blender if necessary. The batter will be very thin. Hand Mixer Method – Whisk together the wet ingredients in a separate medium bowl. Add to the dry ingredients and stir to combine.2 large eggs, ½ cup milk, ½ cup unsweetened applesauce , ¼ cup oil, 2 teaspoon vanilla extract
- Add in the pecans, raisins, and grated carrots. Pulse briefly to combine in the blender, or mix on low speed with hand mixer.½ cup chopped pecans , ½ cup raisins
- Pour the batter into the prepared baking pan. Bake for 30-35 minutes, or until a toothpick comes out clean and the top slightly cracks. Cool in pan for 5 minutes before lifting out onto a wire rack to cool completely. If frosting in the pan, you do not have to take the cake out. Just cool in the pan.
Cream Cheese Frosting
- In a small skillet, brown the butter over medium heat. First the butter will melt fully. Then watch carefully and stir occasionally so it doesn't burn. It will foam, then the milk solids will start to settle at the bottom. Watch for the milk solids to turn from white to brown. Once that happens, immediately remove from heat. Transfer to a large mixing bowl and cool to room temperature.¼ cup butter
- Add the softened cream cheese, powdered sugar, heavy cream, vanilla, and salt. Beat together until smooth without lumps over low to medium speed. Increase the speed to high and beat until fluffy, about 2 minutes.4 ounces cream cheese , 2 cups powdered sugar, 1 teaspoon vanilla, 2 tablespoons heavy cream, ⅛ teaspoon salt
- Spread on cooled cake. Refrigerate leftovers.

Loved this! I had to sub yogurt for apple sauce and opt out of the raisins and pecans; I also chose to do a plain cream cheese frosting (without butter or heavy cream), since I didn’t care too much about how well it was going to hold. Regardless, so good – I made this for my birthday, so it’ll always have a special place in my heart 🙂 Thanks!
Awww – thanks, Rita! I love knowing this recipe has a special place in your heart. Happy Birthday!

Can you replace the eggs with flaxseed.
I did make this it’s very good! Thank you for sharing your blessedness.
Hi June,
Glad you enjoyed it. Yes, that wouldn’t be a problem. You’ll find the crumb will fall apart a little more, but it should work fine.
Best,
Melissa
This is the most amazing cake! I’m making it today for the third time for my son’s birthday! I substituted maple sugar for the sugars because it has a lower glycemic level. So good!
Thanks for sharing, Becky! I appreciate you taking the time to leave me a note.

What can i sub the apple sauce with ? Can i use butter instead of oil ?
Can i use half & half instead of milk. ? Thank you
Hi Alison,
Butter instead of oil and half and half instead of milk would be fine. Instead of applesauce you can swap out an equal amount of yogurt or canned pumpkin.

Melissa
Could I sub the sugar for honey in the cake & frosting? If so what amount do you recommend?
Hi Shelby,
For the cake part, yes. It would just incorporate more moisture so it might have to bake a few minutes longer and it might have a slightly more dense texture. For the frosting I would use a different frosting recipe, one developed with honey. You can search cream cheese frosting made with honey or buttercream made with honey. Hope this helps!
Best,
Melissa
We have several family members who have to be careful with their carb intake. Any suggestions for making this cake lower in carbs, ie a different flour?
Hi Marge,
I wouldn’t recommend using a different flour for this recipe because it would turn out completely different. However, I don’t think using a sugar free sweetener or reducing the sugar would be a problem.
Best,
Melissa
All your recipes are spot on. I have just made this Carrot Cake for our community cafe tomorrow. I split the batter between two tins and it made two lovely well risen cakes. They look and smell amazing. Can’t wait for the feedback tomorrow. Thank you.
I love to hear this. Thanks so much, Bindy! I appreciate you taking the time to let me know.
