Pre-heat the oven to 180C/160C fan forced.
Line a loaf tin with baking paper.
Combine all the ingredients, except for the pumpkin seeds, in a food processor or mix them with a spoon in a large bowl.
Pour the mixture into the prepared tin, then sprinkle the pumpkin seeds on top for some added crunch.
Bake it for 35-40 minutes or until it is cooked through and golden.
Leave it to cool in the tin for a few minutes, then turn out onto a rack to finish cooling before slicing it.
