Easy Peanut butter and chocolate biscuits

Preheat oven to 180°C. Line a baking tray with baking paper and set aside. Place all ingredients into a bowl and combine well. Roll tablespoon sized balls and place on the tray. Push down each one with a fork. Bake for 10-15 minutes. Leave to cool on the tray for 5 minutes and then further cool on a wire rack. Spread Nutella between 2 cookies and press down on each other.
