In a bowl, add the flour and baking powder and mix well
Next, add the Nutella, whisked eggs and melted butter
Mix well using a spoon or your hands until combined and no streaks of flour are visible
Place in the fridge for 10-15 minutes so the cookie dough can firm up (this prevents the cookies from spreading too much)
Form into balls and place a few inches apart on a parchment lined baking sheet (cookies will spread so leave some space)
Bake for 10-12 minutes on the middle rack. Ovens will vary so take them out when they are firm but still slightly soft. Overbaking these cookies will result in a harder/crunchier texture
Allow to cool for 10 minutes then enjoy! The texture should be soft with chewy edges
Notes
Store these cookies in an airtight container
They may harden slightly overnight and become more chewy. You can still enjoy them like that, or if you like really soft cookies, pop them in the microwave for 1 minute
