Light & Spiced Low Calorie Carrot Cake
This low calorie carrot cake manages to be just as tender and spiced as the classic, but with less oil and sugar than you’d expect. Applesauce and a ripe banana do most of the heavy lifting for moisture and natural sweetness.

A thin swipe of light cream cheese frosting on top gives you that tangy finish without burying the cake under a thick layer of icing. It feels like the real thing, just a little lighter.
Why This Low Calorie Carrot Cake Works
The crumb stays remarkably soft because the applesauce and mashed banana replace a lot of the fat, and the whole wheat flour adds a pleasant nutty note instead of tasting dense. Real carrots and warm cinnamon do the rest, so you still get that cozy carrot cake flavor.
The frosting gets its creaminess from light cream cheese whipped with just a spoonful of powdered sugar. It’s tangy, barely sweetened, and lets the spiced cake shine through in every slice.
Ingredients

Cake
- 1 1/2 cups whole wheat flour: adds a gentle nuttiness and extra fiber
- 1/2 cup all-purpose flour: keeps the crumb tender
- 1 1/2 tsp baking powder
- 1/2 tsp baking soda
- 1 1/2 tsp ground cinnamon
- 1/4 tsp ground nutmeg
- 1/4 tsp ground ginger
- 1/2 tsp salt
- 2 large eggs: at room temperature
- 1/2 cup unsweetened applesauce: the main moisture booster
- 2 tbsp vegetable oil: just enough for richness
- 1/2 cup packed brown sugar: gives a deep caramel note
- 1/4 cup granulated sugar
- 1 tsp vanilla extract
- 1 ripe banana, mashed (about 1/2 cup): adds natural sweetness and a soft crumb
- 2 cups finely grated carrots: about 3 medium carrots
Frosting
- 4 oz light cream cheese, softened: Neufchâtel style
- 2 tbsp powdered sugar
- 1/2 tsp vanilla extract
Variations / Substitutions
- Flour swap: Use all-purpose flour for the whole wheat portion if you want a lighter color and milder taste. The cake will lose a little of its nuttiness but still turn out soft.
- Sugar: Light coconut sugar works nicely in place of the brown sugar and keeps the caramel undertone.
- No banana: Replace the mashed banana with an extra 1/4 cup applesauce. The cake will be slightly less sweet but still moist.
- Add-ins: Fold in 1/2 cup chopped walnuts or raisins with the carrots for some crunch and extra texture.
- Frosting: Swap light cream cheese for regular cream cheese if you don’t mind a few more calories. The icing will be thicker and richer.

How to Make Low Calorie Carrot Cake
Step 1: Mix the Dry Ingredients

Heat your oven to 350°F (175°C) and grease a 9-inch round cake pan. In a large bowl, whisk together the whole wheat flour, all-purpose flour, baking powder, baking soda, cinnamon, nutmeg, ginger, and salt until everything looks evenly combined.
The mixture should be uniform and lightly fragrant from the spices. A quick whisk here makes sure the leaveners are spread out evenly.
Step 2: Whisk the Wet Ingredients

In a second bowl, crack in the 2 eggs, then add the applesauce, oil, brown sugar, granulated sugar, vanilla, and mashed banana. Whisk until the mixture is smooth and no streaks of egg white remain.
The banana will leave a few tiny lumps, which is perfectly fine. This wet base will keep the cake from drying out as it bakes.
Step 3: Fold in the Carrots and Flour

Add the grated carrots to the wet bowl, then tip all the dry ingredients right on top. Switch to a rubber spatula and fold the batter just until the flour disappears. You should not see any dry pockets, but a few streaks are better than overmixing.
The batter will be thick and speckled orange with shredded carrot. Stop as soon as it comes together; stirring too much now makes the cake tough.
Step 4: Bake the Cake

Scrape the batter into your prepared pan and smooth the surface. Slide it onto the middle rack and bake for 35 to 40 minutes, until a toothpick poked into the center comes out clean.
Your kitchen will smell like a spice shop around the 25-minute mark. Let the cake rest in the pan for 10 minutes, then turn it out onto a wire rack and leave it to cool completely.
Step 5: Frost and Slice

While the cake cools, beat the softened light cream cheese, powdered sugar, and vanilla together until creamy. Spread the frosting over the top of the cooled cake, leaving a little rim around the edge so you can see the golden crumb. Slice into 12 pieces.
Each slice gets a thin, tangy layer of frosting that tastes indulgent without drowning the spice underneath. Serve right away, or pop it in the fridge for cleaner cuts later.
A Few Tips Before You Start
- Bring your eggs and cream cheese to room temperature so everything blends into a smooth batter and frosting without lumps.
- Grate the carrots on the fine side of the box grater. The short shreds melt into the crumb and give you a tender cake rather than chewy bits.
- Let the cake cool completely before frosting, or the icing will soften and slide right off.
- For a deeper spice warmth, add a tiny pinch of cardamom or allspice to the dry mix.
Bake times for different pans:
| Pan Shape | Size | Bake Time |
|---|---|---|
| Round cake pan | 9-inch | 35–40 mins |
| Square pan | 8×8-inch | 30–35 mins |
| Loaf pan | 9×5-inch | 50–55 mins |
| Muffin tin | 12 cups | 20–25 mins |
Keeping Carrot Cake Fresh
- Refrigerate: Store slices in an airtight container in the fridge for up to 5 days. The cold keeps the cream cheese frosting safe and the crumb pleasantly firm.
- Reheating: Microwave a slice for 15 to 20 seconds to take the chill off the frosting and soften the cake.
- Serve Cold: The cake is really good straight from the fridge too, with a cup of coffee.
Frequently Asked Questions
Can I make this carrot cake gluten-free?
Yes, use a 1:1 gluten-free flour blend in place of the whole wheat and all-purpose flours. The texture stays moist.
Does the banana make the cake taste like banana?
Not strongly. The cinnamon and carrot are the main flavors, but if you’d rather skip it, use 1/4 cup more applesauce instead.
Can I just leave off the frosting?
Absolutely. The unfrosted cake is still spiced and soft, and it keeps well without refrigeration for a day or two.
What if I want to add nuts or raisins?
Go right ahead. Fold in 1/2 cup chopped walnuts or raisins when you mix in the carrots. It adds a little crunch and chew.
