Ingredients

For the Cake (No Sugar, No Flour):

  • 2 cups finely grated carrots (about 3 medium carrots)

  • 3 medium very ripe bananas (the spottier, the better – natural sweetness)

  • 2 cups almond flour (not almond meal; fine blanched almond flour works best)

  • 3 large eggs (or flax eggs for vegan: 3 tbsp flaxseed meal + 9 tbsp water)

  • ¼ cup coconut oil, melted (or unsalted butter if not dairy-free)

  • 1 tsp vanilla extract

  • 1½ tsp baking soda

  • ½ tsp salt

  • 1½ tbsp ground cinnamon

  • ½ tsp ground nutmeg

  • ½ cup unsweetened shredded coconut (optional, for texture)

  • ¼ cup chopped walnuts (optional, plus extra for topping)

For the “No Sugar” Cream Cheese Frosting:

  • 1 cup raw cashews (soaked in hot water for 30 minutes)

  • ¼ cup full-fat coconut milk (the thick cream from the top of a chilled can)

  • 2 tbsp coconut oil, melted

  • 1 tsp vanilla extract

  • ½ tsp stevia or monk fruit extract powder (optional, if you want extra sweetness; omit for completely unsweetened)

  • 2 tbsp lemon juice (balances the sweetness and adds tang)

*Note: The cake itself is sweet enough from banana and carrot. If you are strictly zero-sugar (including zero fruit sugars), swap bananas for 1 cup unsweetened applesauce + ¼ cup erythritol.*

Instructions

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C).
Grease an 8-inch round cake pan with coconut oil. Line the bottom with parchment paper for easy removal. (Intensity: Low – 2 minutes)

Step 2: Mash the Bananas

In a large mixing bowl, mash the 3 ripe bananas with a fork until completely smooth and runny. This is your sugar substitute. (Intensity: Low – 2 minutes)

Step 3: Add Wet Ingredients

To the mashed bananas, add the melted coconut oil, eggs, and vanilla extract. Whisk until fully combined. The mixture will look glossy. (Intensity: Low – 1 minute)

Step 4: Add Dry Ingredients (No Flour, Remember!)

Add the almond flour, baking soda, salt, cinnamon, and nutmeg directly into the wet mixture. Stir with a rubber spatula until just combined. Do not overmix – almond flour batters are forgiving, but overmixing can make the cake dense. (Intensity: Low – 2 minutes)

Step 5: Fold in Carrots and Extras

Fold in the grated carrots gently. Then fold in shredded coconut and chopped walnuts (if using). The batter will be thick and chunky – that’s correct. (Intensity: Low – 2 minutes)

Step 6: Bake

Pour the batter into the prepared pan. Smooth the top.
Bake for 30–35 minutes. Check at 30 minutes: Insert a toothpick into the center. It should come out clean or with a few moist crumbs (not wet batter).
Note: Almond flour cakes brown faster than wheat flour cakes. If the top is getting too dark at 25 minutes, loosely tent with foil. (Intensity: None – just wait)

Step 7: Cool Completely

Let the cake cool in the pan for 15 minutes, then transfer to a wire rack to cool completely. This is critical – almond flour cakes are fragile when warm. (Intensity: Very Low)

Step 8: Make the Frosting (While Cake Cools)

Drain the soaked cashews. In a high-speed blender, combine:

  • Soaked cashews

  • Coconut milk cream

  • Melted coconut oil

  • Vanilla

  • Lemon juice

  • Stevia/monk fruit (if using)

Blend on high for 60–90 seconds until completely silky smooth. Scrape down sides as needed. Refrigerate for 20 minutes to thicken. (Intensity: Medium – requires a good blender)

Step 9: Assemble

Once the cake is at room temperature, spread the cashew frosting generously on top. Garnish with a few chopped walnuts or a sprinkle of cinnamon. (Intensity: Very Low)

Step 10: Slice and Serve

For clean slices, chill the frosted cake in the fridge for 30 minutes before cutting. Serve cold or at room temperature. (Intensity: None)


Storage Instructions

  • Counter: 1 day (in a sealed container – almond flour dries out quickly)

  • Fridge: 5 days (flavor improves after day 2)

  • Freezer: Wrap slices tightly; freeze up to 3 months. Thaw overnight in fridge.


Pro Tips for Success (No Sugar No Flour Baking)

  1. Don’t skip the banana ripening. Green bananas will not sweeten the cake. If you have no ripe bananas, roast unpeeled bananas at 300°F for 15 minutes until black – they become sugary soft.

  2. Measure almond flour correctly. Scoop and level – don’t pack it. Too much almond flour yields a dry, crumbly cake.

  3. Grate carrots finely. Large chunks of carrot release water unevenly and can create soggy pockets. Use the small side of a box grater.

  4. The toothpick test is king. Because there is no flour or refined sugar, this cake goes from “perfectly moist” to “overbaked dry” in about 3 minutes. Check early.

  5. For a nut-free version: Replace almond flour with 1 cup sunflower seed flour + 1 cup fine oat fiber (not oat flour). Add 1 extra egg. Note: Sunflower seed cake may turn slightly green from baking soda – it’s harmless and tastes fine.


Frequently Asked Questions

Q: Is this really “no sugar”?
A. Yes. Zero added cane sugar, honey, maple syrup, or artificial sweeteners (unless you choose to add stevia to the frosting). All sugars come from bananas and carrots, which are whole foods.

Q: Can I make it without bananas?
A. Use 1 cup unsweetened applesauce + 3 tbsp erythritol or allulose. The texture will be slightly more dense but still good.

Q: Why is there no frosting nutrition for “allowed”?
A. The recipe allows the cashew frosting as optional. The nutrition panel above is for the cake alone. If you want a zero-frosting version, the cake stands beautifully on its own.

Q: My cake sank in the middle – why?
A. Almond flour lacks gluten structure. Overmixing or opening the oven too early can cause sinking. Next time, let the cake cool in the oven with the door cracked for 10 minutes.


Final Note from the Chef

This cake proves that “no sugar no flour” doesn’t mean “no joy.” It’s dense enough to satisfy, spiced enough to feel like a splurge, and clean enough to eat for breakfast. Slice it up, share it with someone who thinks healthy baking tastes like cardboard, and watch them ask for seconds.
