In a microwaveable container, add the Nutella and milk. Microwave for 30 seconds at a time just until the Nutella is warm enough to mix into the milk completely. Set aside.
In a large bowl, combine the flour, baking powder and salt until completely combined. Make sure to get rid of any baking powder lumps.
In a medium bowl, beat the eggs. Add the oil and Nutella/milk mixture, then mix until fully combined.
Add the dry ingredients to the wet ingredients, and mix just until combined. Don’t worry if there are some lumps; try to smash a few against the side of the bowl, but don’t go wild with it.
Add the batter to the waffle maker (how much depends on the size of your waffle maker; mine holds ⅓ cup of batter per waffle) and cook until there’s almost no steam coming out of the waffle maker. Remove the cooked waffles and repeat with the rest of the batter.
Serve warm with any toppings you’d like!
Recipe Notes
Feel free to use another kind of chocolate hazelnut spread or another kind of milk.
