Ingredients (Estimated for an 8-inch Square Pan, About 9 Servings)

1 1/2 cups (140 g) rolled oats
1 large apple, peeled and finely grated (about 1 cup)
1/2 cup (50 g) finely grated carrot (about 1 medium carrot)
2 large eggs
1/3 cup (80 ml) pure maple syrup or honey
1/4 cup (60 ml) neutral oil or melted coconut oil
1/2 cup (120 ml) milk of choice, dairy or plant-based
1 tsp (5 ml) pure vanilla extract
1 tsp (2 g) ground cinnamon
1 tsp (4 g) baking powder
1/4 tsp (1.5 g) fine salt

Ingredient Notes

Blended oats take the place of flour and give the cake its structure. Grated apple and carrot add moisture and natural sweetness, so you can keep the added sweetener modest. Eggs bind the batter, and baking powder helps the cake rise. If you use a plant-based milk, choose an unsweetened variety so the cake does not become too sweet.

Equipment You Will Need

8-inch square baking pan
Parchment paper or cooking spray
Blender or food processor
Box grater or fine grater
Mixing bowl and spatula

How to Make Flourless Apple Carrot Oat Cake

Preheat the oven to 350°F (175°C). Grease an 8-inch square pan or line it with parchment paper, leaving a little overhang to lift the cake out later.
Add the rolled oats to a blender or food processor. Pulse or blend for 30 to 45 seconds, until the oats look like coarse flour with a few larger flakes remaining. Pour them into a mixing bowl.
Peel and finely grate the apple. Grate the carrot. Squeeze any excess liquid from the apple if it looks very wet, then set both aside.
In a separate bowl, whisk the eggs, maple syrup or honey, oil, milk, and vanilla until smooth and slightly frothy, about 1 minute.
Add the cinnamon, baking powder, and salt to the oat flour and stir to combine.
Pour the wet ingredients into the dry ingredients and stir until no dry patches remain. The batter should be thick but spoonable.
Fold in the grated apple and carrot until evenly distributed.
Spread the batter evenly in the prepared pan and smooth the top with a spatula.
Bake for 30 to 40 minutes, until the top is golden and a toothpick inserted into the center comes out with moist crumbs but no wet batter. Baking time varies with oven and pan, so start checking at 30 minutes.
Let the cake cool in the pan for about 15 minutes, then lift it out with the parchment and cool completely before slicing. Slicing too early can cause crumbling.

Pro Tips for the Best Results

Blend the oats until they look like coarse flour. Fully powdered oats can make the cake dense, while large flakes can make it crumbly.
Grate the apple and carrot finely so they blend into the batter and do not leave wet streaks.
Squeeze excess moisture from the grated apple if it is very juicy.
Let the batter rest for 5 minutes before baking so the oats can absorb some liquid.
Use a toothpick test rather than relying only on color, because the cake may look golden before the center is set.

Common Mistakes to Avoid

The most common issue is a gummy center. This usually happens when the cake is underbaked or sliced while still warm. Bake until the center is set and let it cool fully. A dry cake often comes from over-blending the oats or baking too long. Check the cake at the earliest time in the range. A cake that falls apart may need more time to cool or a slightly longer rest after baking.

Variations and Substitutions

Add 1/4 cup (30 g) chopped walnuts or pecans for crunch.
Add 1/3 cup (40 g) raisins or chopped dates for extra chew.
Use half of the sweetener with an extra ripe mashed banana if you prefer a softer flavor.
Swap the cinnamon for a pinch of ground ginger or nutmeg for a different spice profile.

Serving Suggestions

Serve the cake plain, with a spoonful of plain Greek yogurt, or with a light drizzle of maple syrup. It also pairs well with coffee, tea, or a glass of cold milk.

Storage and Reheating

Store cooled cake covered in an airtight container in the refrigerator. Most cakes like this keep for several days. For freezing, wrap individual slices tightly and freeze them for up to about 2 months. Thaw slices in the refrigerator or at room temperature. You can warm them briefly in a microwave for a softer texture.

Frequently Asked Questions

Is this cake truly flourless?

Yes. The base is made from blended rolled oats, so no wheat flour is needed.

Can I make it without refined sugar?

Yes. This version uses maple syrup or honey, plus the natural sweetness from apple and carrot.

Why did my cake turn out gummy?

It was likely underbaked or cut while still warm. Bake until a toothpick comes out with moist crumbs and let the cake cool completely.

Yes. It can be baked a day ahead and stored covered in the refrigerator.

Can I use a different pan?

You can use a similar-sized pan, but check for doneness early because baking time may change.
