Healthy Banana Bread (Low Added Sugar, High Protein)

The bananas do the sweetening here, so they need to be properly ripe: heavily freckled or almost black. That is why this loaf needs only 30g of maple syrup in total. Greek yogurt keeps it moist, and a little protein powder gives each slice 11g of protein.

Sliced loaf of healthy banana bread topped with walnuts and banana, on a wooden board

Ingredients

  • 3 very ripe bananas (about 300g peeled), plus half a banana to decorate (optional)
  • 3 eggs
  • 200g 0% fat Greek yogurt
  • 2 tbsp olive oil (30ml), or melted coconut oil
  • 1 and a half tbsp maple syrup (30g)
  • 1 tsp vanilla extract
  • 150g wholemeal flour
  • 50g ground almonds
  • 40g unflavoured or vanilla protein powder (whey)
  • 2 tsp baking powder, half a tsp bicarbonate of soda and a pinch of salt
  • 2 tsp ground cinnamon
  • 30g walnuts, roughly chopped

Method

  1. Heat the oven to 170C (150C fan). Line a 900g (2lb) loaf tin with baking paper.
  2. Mash the bananas in a large bowl until almost smooth. Whisk in the eggs, yogurt, oil, maple syrup and vanilla.
  3. In another bowl, mix the flour, ground almonds, protein powder, baking powder, bicarbonate of soda, salt and cinnamon.
  4. Fold the dry ingredients into the wet ones with a spatula until just combined. Stop as soon as you cannot see any dry flour; overmixing makes it tough. Fold in most of the walnuts.
  5. Scrape into the tin, level the top and scatter over the rest of the walnuts. Lay a halved banana on top, if using.
  6. Bake for 50 to 60 minutes, until risen and a skewer pushed into the middle comes out clean. If the top browns too quickly, cover it loosely with foil after 35 minutes.
  7. Cool in the tin for 15 minutes, then lift out and cool completely on a rack before slicing. Keep in an airtight container for up to 3 days, or freeze in slices for up to 3 months.

Why it works

Each slice has about 11g of protein and 216 calories. More than 20% of its energy comes from protein, which is the threshold for calling a food "high protein" in the UK.

Only 3g of added sugar a slice. The sweetness comes from very ripe bananas and cinnamon; the only added sugar is the maple syrup. Most banana bread recipes add a lot of sugar on top of the bananas. The NHS advises adults to have no more than 30g of free sugars a day.

The protein comes from the eggs, Greek yogurt, almonds and protein powder. No protein powder? Use another 40g of ground almonds instead. Each slice will have about 9g of protein.

Wholemeal flour and walnuts add fibre and unsaturated fat. That makes a slice a sensible snack before or after training, or for anyone who wants something sweet that keeps them going rather than leaving them hungry an hour later.

Allergy notes. This contains eggs, milk, wheat and tree nuts. For a warm breakfast with oats and fruit, try the baked oats with apple and cinnamon.
