Our kidney bean brownie recipe is about to become your new go-to bake. It’s quick, fuss-free and all made in one blender – ideal for busy days when you still want something homemade. The beans create a perfectly fudgy texture while adding a hidden protein boost (no one will guess!).

What you'll need:

  • 1 x 400g tin kidney beans, drained and rinsed
  • 2 eggs
  • 3 tbsp cocoa powder
  • 60ml maple syrup or honey
  • 2 tbsp coconut oil (melted)
  • 1 tsp vanilla extract
  • 1/2 tsp baking powder
  • Pinch of sea salt
  • 50g dark chocolate chips (optional but recommended!)

Method:

  1. Preheat your oven to 180°C/Gas Mark 4 and line a small baking tin with parchment paper.
  2. Add the kidney beans, eggs, cocoa powder, maple syrup, coconut oil and vanilla extract into a blender or food processor. Blend until completely smooth.
    Top tip: Take an extra minute here – the smoother the mix, the better the texture.
  3. Pour the mixture into a bowl and stir through the baking powder, salt and chocolate chips.
  4. Transfer the batter into your lined baking tin, smoothing out the top evenly.
  5. Bake for 20–25 minutes, until just set in the middle.
  6. Leave to cool in the tin for at least 10 minutes before slicing – they’ll firm up as they cool.
  7. Serve warm or cold with yoghurt, berries or simply on their own for a delicious, protein-packed treat.
