Combine all ingredients in a bowl and mix with a spoon until smooth. Eat immediately or refrigerate for up to a week.
Tips
Try a different nut butter if you like - almond butter and cashew butter both work well.
Add a sprinkle of cinnamon on top for extra flavour.
This peanut butter fluff is great spread on toast topped with sliced banana. Also delicious as a dip for fresh fruit, or as a topping for pancakes and pikelets.
