Have you done this before? No
Tools for the recipe: Regular mixing whisk and spatula
Ingredient substitute: Coconut flour instead of regular flour
Experience doing the recipe: This recipe is on point. It is super quick and delicious. I warmed up the Nutella a bit as it felt a bit difficult to mix it with the eggs as I mixed everything by hand. This recipe requires arm power and strong will since the smell of Nutella makes you want to lick that bowl. I added the coconut flour and my mix turned almost into a dough. So I formed little balls and placed them in a cupcake baking pan. The 20 min bake mark was right and although I did not have a batter the brownies came out crusty on the outside and oozing Nutella in the middle. Delicious and evil as you cannot eat only one
Would you try doing the recipe again? Yes, maybe I will experiment with doubling the recipe as the ones I baked did not last very long
