Place all ingredients in a blender and pulse to combine. Alternatively, mash the banana with a fork and then, using a whisk, incorporate the egg and milk. Add the rest of the ingredients and whisk gently until combined. Whichever way you to choose to prepare these, take care not to over work the mixture.
½ small banana, 1 large egg, 250 ml almond milk, 125 g spelt flour, 2 teaspoons baking powder, pinch of salt, 1 tablespoon rapeseed oil, 1 teaspoon vanilla extract
