🍎🥕 Flourless Sugar-Free Oatmeal, Apple & Carrot Cake
Introduction
This Flourless Oatmeal, Apple & Carrot Cake is a wholesome alternative to traditional cakes. It contains no wheat flour and no added refined sugar, while rolled oats provide the structure normally supplied by flour. Grated apples and carrots add moisture, natural sweetness, color, and a wonderful fruity-vegetable flavor.
The result is a soft, tender, lightly chewy cake with warm cinnamon, juicy apple, and naturally sweet carrot in every bite. It works beautifully as a breakfast cake, afternoon snack, healthy dessert, or meal-prep treat.
🍰 Recipe Information
Preparation: 20 minutes
Resting: 10 minutes
Baking: 40–45 minutes
Total: About 1 hour 15 minutes
Yield: 8–10 slices
Pan: 20 cm / 8-inch round cake pan
Oven: 175°C / 350°F
🥕 Ingredients
Main Ingredients
- 2 cups (200 g) rolled oats
- 2 medium apples, about 250–300 g total
- 2 medium carrots, about 150–180 g total
- 3 large eggs
- ½ cup (120 ml) milk, dairy or unsweetened plant milk
- 2 tablespoons melted coconut oil or mild olive oil
- 1 teaspoon vanilla extract
- 1½ teaspoons ground cinnamon
- 1 teaspoon baking powder
- ¼ teaspoon salt
Optional Natural Flavor Additions
- ½ teaspoon ground ginger
- ¼ teaspoon nutmeg
- ½ teaspoon orange zest
- 2 tablespoons chopped walnuts or pecans
- 1 tablespoon chia seeds or ground flaxseed
Optional Sweetness
If your apples aren’t particularly sweet, you can add a zero-calorie sweetener such as stevia or erythritol according to the product’s recommended sweetness. This keeps the recipe free from added sugar.
For a strictly no-added-sweetener version, simply omit it—the apples and carrots provide the sweetness. Similar versions rely primarily on apples, carrots and optional dried fruit for sweetness.
Important: Raisins, dates, honey and maple syrup are naturally sweet but still contain sugars, so they are intentionally excluded from this strict no-added-sugar version.
🥣 Method
Step 1 — Prepare the Oven
Preheat your oven to:
175°C / 350°F
Line an 8-inch (20 cm) cake pan with parchment paper and lightly grease the sides.
This prevents the moist cake from sticking.
Step 2 — Turn the Oats Into Oat Flour
Place approximately 1½ cups of the rolled oats into a blender or food processor.
Blend until they become a fine, flour-like powder.
Keep the remaining ½ cup oats whole.
This combination creates a better texture: the blended oats give the cake structure, while the whole oats provide a pleasant, slightly chewy bite. Blending oats into a flour-like consistency is commonly used in flourless oat cakes.
Step 3 — Prepare the Apples
Wash and grate the apples.
You can leave the skin on if desired.
After grating, gently squeeze out some—but not all—of the excess liquid.
Don’t completely dry the apples because their moisture is important for creating a soft cake.
Step 4 — Prepare the Carrots
Peel and finely grate the carrots.
For the best texture, use the smaller holes of a box grater.
If the carrot produces a lot of liquid, lightly squeeze it.
Step 5 — Prepare the Wet Mixture
In a large mixing bowl, whisk together:
- 3 eggs
- 120 ml milk
- 2 tablespoons melted coconut oil or olive oil
- 1 teaspoon vanilla
Whisk for approximately 1 minute, until everything is well combined.
Add the grated apples and carrots.
Mix thoroughly.
🌾 Step 6 — Add the Oat Mixture
Add:
- blended oat flour
- whole rolled oats
- baking powder
- cinnamon
- salt
- ginger, if using
- nutmeg, if using
Fold everything together with a spatula.
Don’t overmix.
The mixture should be thick and moist, similar to a very thick oatmeal batter.
Step 7 — Let the Batter Rest
Allow the mixture to sit for approximately 10 minutes.
This is an important step because oats absorb liquid as they sit.
After 10 minutes, check the consistency.
If it is too wet:
Add 1–2 tablespoons of oats.
If it is too dry:
Add 1–2 tablespoons of milk.
The final batter should be thick but spreadable.
🍎 Step 8 — Add the Optional Ingredients
For extra texture, gently fold in:
- chopped walnuts
- pecans
- chia seeds
- orange zest
You can also add a little extra cinnamon.
For a particularly autumn-inspired flavor, cinnamon + ginger + orange zest works beautifully.
🎂 Step 9 — Transfer to the Pan
Pour the batter into the prepared cake pan.
Use a spatula to spread it evenly.
Gently tap the pan against the counter once or twice to remove large air pockets.
For decoration, arrange a few very thin apple slices over the surface.
Sprinkle a little cinnamon on top.
🔥 Step 10 — Bake
Place the cake in the center of the preheated oven.
Bake at:
175°C / 350°F for approximately 40–45 minutes.
The cake is ready when:
- the surface is golden
- the center feels set
- the edges are slightly firm
- a toothpick inserted into the center comes out mostly clean
Because apples and carrots contain considerable moisture, this cake may remain slightly moist in the center even when completely baked.
Comparable flourless oat/apple/carrot recipes bake around 35–45 minutes depending on the pan and formulation.
❄️ Step 11 — Cool
Remove the cake from the oven.
Allow it to cool in the pan for 10–15 minutes.
Then carefully transfer it to a cooling rack.
For the cleanest slices, let it cool completely before cutting.

❤️ Why You’ll Love This Cake
🌾 Flourless
There is no wheat flour. Oats provide the structure instead. If you need it to be gluten-free, choose certified gluten-free oats, since ordinary oats can have cross-contact with gluten-containing grains.
🍎 Naturally Sweet
Fresh apples and carrots contribute natural sweetness without requiring refined sugar.
🥕 Moist & Tender
The moisture from the grated fruit and vegetables keeps the cake soft.
💪 Satisfying
Oats contribute complex carbohydrates and dietary fiber, while eggs provide protein.
☕ Perfect With Coffee
The cinnamon, apple and carrot combination makes this especially good with coffee or tea.
🥣 Meal Prep Friendly
The cake can be prepared ahead and portioned into individual slices.

📜 History & Formation
The idea behind this cake combines several traditions of wholesome home baking.
Oat-based cakes use oats as a grain-based alternative to conventional wheat flour. Modern healthy-baking recipes increasingly grind rolled oats into a flour-like consistency, allowing them to function as the main dry ingredient.
Carrot cakes, meanwhile, have a long history of using naturally sweet vegetables to create moist baked goods. Apples are another classic baking ingredient because they provide both sweetness and moisture.
This recipe brings these ideas together into a modern flourless, no-added-sugar breakfast cake. Contemporary versions commonly combine oats with grated apples and carrots and use eggs or other binders to create the cake structure.
🔬 The Formation of the Cake
The chemistry of this cake is particularly interesting because there is no conventional flour.
Oats
Ground oats provide starch and structure.
Eggs
Egg proteins coagulate during baking and help hold the cake together.
Apples
Apples provide moisture, natural sugars and fruity flavor.
Carrots
Carrots add moisture, fiber, natural sweetness and color.
Baking Powder
Baking powder releases gas during baking, helping the relatively dense oat batter rise.
Oil
A small amount of oil improves tenderness and prevents the cake from becoming too dry.
Cinnamon
Cinnamon adds warmth and enhances the perception of sweetness.
Together, these ingredients create a cake that is moist, dense but tender, and naturally aromatic.
👩🍳 Chef’s Tips
1. Use sweet apples
Naturally sweet varieties will give you a better result when you’re avoiding added sugar.
2. Don’t over-squeeze the apples
You need some of their moisture.
3. Don’t overmix
Once the oats are incorporated, mix just until combined.
4. Let the batter rest
This allows the oats to absorb some of the liquid and improves the final texture.
5. Don’t cut it immediately
The cake continues to set while cooling.
6. Want a softer cake?
Blend all the oats into oat flour instead of leaving half whole.
7. Want more texture?
Keep ½ cup of oats whole and add walnuts.
