Easy reduced sugar recipe for moist banana loaf or cake – made with chestnut flour and dressed up French style, topped with walnuts and figs.
The wind has helped bring Autumn to Paris with skydiving leaves. At many metro exits, guys are selling roasted chestnuts on their familiar beaten-up trolleys. As that first smell of woodsmoke hit me in the garden today, my thoughts returned to chestnuts. With three bananas looking at me in the kitchen, rather spotted and brown, it’s always a perfect excuse to conjure up a moist banana chestnut loaf.
Reducing Sugar in Cakes and Desserts
The kids love banana bread for breakfast: you may have tried this banana chestnut coffee cake recipe, inspired by a UK celebrity chef with the coffee but, in the end, it needed LESS THEN HALF of the sugar.
If you know my recipes by now, I’ve been so inspired by French pastry chefs. Ever since I learned that too much sugar kills the flavour of pastries and cakes, I consistently reduce sugar. As bananas are naturally sweet enough, even adding a little soft brown sugar is treat enough.
Are Chestnuts and Conkers the Same?
The conkers from horse chestnut trees are not edible – unlike the sweet edible chestnuts so popular in France.
The edible chestnuts are so popular in both France and in Corsica. With the Corsican family connection, we love using chestnut flour in many Autumnal recipes (have you tried this Chestnut Flour Tart with Pumpkin and Mushrooms? It’s Autumn on a plate!)
It adds that nutty intrigue and so that it’s not overpowering, use a a mix of plain flour with the chestnut flour, depending on the recipe.
Chestnut flour does tend to make cakes rise less, so although it doesn’t look the most photogenic of cakes, the taste is what counts.
What is a Popular French Cake?
I find a French “cake” rather amusing since it can be a bit confusing. The French call a Cake (pronounced KeK) – but it’s not a round cake as we know it like a sticky orange caramel cake, or chocolate ginger passion cake. It’s appearance is more like a loaf in shape, as the cake is baked in a loaf tin. French cakes like chestnut cake in Corsica are popular and so merging the two with British banana bread meets together in this moist banana chestnut loaf.
If you look around the patisserie windows around Paris, you’ll see that many French pastry chefs top their cakes with fancy frills, such as quartered fresh figs, or candied fruits. So it’s rare to see a bare, naked-topped French cake in any Parisian patisserie. If you do see one, tell me and I’ll eat my cake!
As a result, we often get mixed up between banana bread, banana cake and banana loaf. I’m calling it a loaf but perhaps I should say cake, like the French? Does it really matter? Just try it and you’ll decide for yourself.
Moist Banana Chestnut Loaf
- 3 bananas very ripe

- To decorate, gently heat the honey and brush it on the top of the loaf, adding extra walnuts.
Delicious served warmed with a scraping of butter or chestnut spread.
