Unexpected discovery about banana bread and carrot cake

Profile picture for user ll433

I've been making a lot of banana bread and carrot cake over the last week, trying to come up with a recipe for my mother. My mother works as a chef at a kindergarten and she's been tasked with making these two cakes next week for 100 children. 

My mother has almost never baked in her life, so I need a recipe that is very, very simple. The school has also requested that the recipe is minimally sweet, has little oil, lots of bananas and carrots, and preferably no dairy. 

So you see I have problems with dry and/or overly dense cakes. I'm looking at essentially a healthy quick bread type cake without egg beating etc.

I've finally arrived at recipes that I'm happy with. I'm so sick of eating carrot cake and banana bread and the kgs are certainly piling on. I'm finishing this post and putting in a good 12k run to keep things somewhat manageable.

But here's something very interesting I found out. In my attempt to keep things so simple for my mother, I thought of always having the wet and the dry separate, and I always lumped the mashed banana and the grated carrot into the wet ingredients. These would be mixed into the egg/sugar/oil mixture, and then the whole wet contingent would be mixed with the dry, minimally and gently.

Here's the thing: this actually creates a much denser crumb structure. If everything else is kept constant, mixing the dry and the wet, AND THEN gently stirring in the banana/shredded carrot, will give you a more aerated crumb. 

I don't know if everyone already knows this, but discovering this has changed the game for the kind of recipe I'm trying to develop for my mother. Might be worth implementing for any similar sort of inclusions into cake batter - I will need to a whole lot more for her in the coming weeks, e.g. sweet potato, courgette/zucchini, beetroot...

No biggie, I'm pretty sure you'll nail the formula soon!

Lin, you might wanna try isolated steaming that I always did during college days. It's basically just wrapping cake pan with cling wrap, so steaming moisture won't get in. I managed to lower sugar as low as 50% (to my experience) without drying out the cake (because it's isolated).

The downside, you have to serve it as slices. It's best to keep egg whites tho at the very least, to make soft peak meringue, going semi-chiffon cake like texture

Hi Lin, I have found that coconut flour helps hold moisture in quick breads. The general guideline is you can replace up to 20% of the flour with coconut flour and add an equal volume of liquid to the recipe. Coconut flour is high in fiber and it absorbs a lot of water.

Are you saying you can't use eggs either?

I also think the coconut flour could be a great addition here. And as you say, it is strongly absorbent of moisture and will then need lots of eggs, say 4 or 5?! Can you imagine the lovely taste?

Great discovery about the order of mixing, Lin. A bit like not over folding, I'm thinking.

It was precisely because I wanted to guard against my mum over folding that I thought of adding the banana/ carrot to the wet ingredients rather than after the flour addition. Who would have thought!

Thanks Debra, I didn't think of that. I can use eggs in the recipe, just not milk or butter. Would you recommend adding an equal proportion of eggs and oil, then? I could also experiment with adding more bananas to increase moisture. I've never used coconut flour, only coconut milk, coconut cream and dessicated coconut. 

Eggs help with structure, but you don't need to increase them, the sugar or the oil for coconut flour. You can add plain water. But why not try increasing the bananas first, since that was one of the preferences and they bring a lot of water. Back off the bananas if the crumb gets pastey. That's the biggest problem increasing bananas and other fruit or vegetable mashes that weigh down the structure. If you're already having trouble with the density, then test a batch with coconut flour without adding any more moisture.

Unlike desiccated coconut, milk or cream, coconut flour doesn't bring a coconutty flavor, so you don't have to worry about that where you don't want it.

Lastly, if/when you feel the consistency of the batter is right but you aren't getting enough rise, you can try adding or increasing baking powder. You'll find out if there's enough structure to support it. Be open to the possibility that you may need to develop the gluten a bit more, and maybe that's why you're getting less density by mixing in the banana or carrot after everything else has been combined. I have found, particularly with my whole grain muffins, that they benefit from vigorous whisking. Try not being so gentle :)

Thanks, Debra. Appreciate it. Especially interesting that you've found that vigorous whisking is needed for whole grain muffins! I'll start by substituting a small bit of flour with coconut flour, whisking a little more, and go from there. 

Just some general improvements:

Ingredients:

125g wholemeal flour, sifted fine sieve or atta

2 tsp baking powder + pinch salt add to sifted flour

2 tsp ground cinnamon ditto

100g sultanas

35g butter, melted + 15g evoo

2 egg or 1 egg + 1 white

1 tbsp marsala or sweet sherry or milk

3 ripe medium bananas, mashed

Sml handful sunflower seeds

  • Oven heat to 180 fan
  • Use oval bread tin - butter and cut baking paper base insert
  • Pour blg water on sultanas, soak 10m, squeeze dry and chop with knife
  • Make flour mix
  • In Kwood bowl, mash nanas w K beater (if soft) or wooden pestle
  • Add sultanas, eggs, wine, seeds, butter and mix w K
  • Change to folding tool and trickle in flour mix
  • When mixed quickly scrape into tin and bake w oven now change to T&B
  • Bake 30m, then change to fan and bake to clean skewer - about 20m more

This looks great. Appreciate your sharing these tweaks. 

For fun I used ChatGPT  for the following : 'vegan no sugar banana bread recipe in grams with bakers percentages  20 × 10 × 10 cm pan'

You could add your specific requirements.

Here's the result:

Awesome! Here's a second cleaner versiononly bananas for sweetness, no maple syrup at all.
This keeps it 100% naturally sweetened from fruit only. 🍌


Vegan No-Sugar Banana Bread (Sweetened Only with Bananas)

IngredientGramsBaker's %
All-purpose flour200100%
Ripe bananas (mashed)300150%
Plant-based milk6030%
Neutral oil4020%
Baking powder84%
Baking soda21%
Salt31.5%
Cinnamon (optional)21%
Vanilla extract52.5%
Walnuts (optional)5025%

What's different:

  • More bananas (300g vs 240g) to boost natural sweetness.
  • Less plant milk (60g instead of 80g) to balance moisture.
  • No maple syrup at all.
  • Texture is still moist but slightly denser (very delicious).

Instructions:

Same as before:

Quick Instructions:

  1. Preheat oven to 175°C (350°F).
  2. Mash bananas well. Mix with plant milk, oil, maple syrup, and vanilla.
  3. Separately whisk flour, baking powder, baking soda, salt, and cinnamon.
  4. Combine wet and dry ingredients gently. Fold in walnuts if using.
  5. Pour into greased or lined pan.
  6. Bake 50–60 minutes, or until a skewer comes out clean.
  7. Cool before slicing!

Would you also like me to show a baker's percentage diagram (like a pie chart) to help visualize it? 🎨
It could make adjusting future recipes even easier!

Kindergartners have a chef? 😄

All meals they get are warm and prepared in the kitchen on site. The school used to buy all their pastries for the final break but have now asked my mother to give it a go. Some kids stay the whole day as it's kindergarten + after school childcare.
