Use very ripe bananas. The riper the bananas, the better. Softer, sweeter and more intensely flavoured, works better for cake mixture.
Let the honey mixture cool completely. Don’t add the eggs to a warm mixture, the heat might begin to cook them. Once cooled, add the eggs one at a time and whisk well to emulsify.
Mix gently. Once the wet ingredients are added to the flour, be gentle. A few small lumps are perfectly fine. Overmixing might develop gluten in the flour, which can leave the cake with a tougher, less tender crumb.
Keep the baking paper in place. Before lining the loaf tin, lightly butter the inside around the edges. This helps the baking paper cling to the tin and prevents it from folding in as you pour in the batter.
Choose your honey. I have made this cake with both dark and regular honey, and both work beautifully. Personally, I prefer dark honey, as it gives the cake a deeper, more distinctive flavour with subtle molasses notes, as well as a wonderfully rich colour.
Roast the walnuts first. Toasting the walnuts before chopping them makes a noticeable difference. Try roasting them with a pinch of salt.
Give it time to rest. This cake texture and flavour improve as it cools. Even better, wrap the cooled cake and leave it until the following day, the honey and banana flavours deepen, and the crumb becomes beautifully moist.
