Notes
Ingredient Notes and Shopping Tips
Nutella: When baking, I always use brand names to achieve the best results.Your Nutella should be smooth and spreadable. If its not microwave for 20-30 seconds.
Eggs: Whisk until the eggs are light yellow in color and tripled in size. This will give your brownies height.
Also, make sure they're at room temperature to help them incorporate smoothly.
Tips
Incorporate Air: The secret to making the perfect Nutella brownies is to make sure you whip your eggs up.
Easy Measuring: Spray your measuring cup with nonstick spray to prevent the Nutella from sticking.
Use Foil: Line your pan with foil for easy cleanup and removal.
Don't overbake: Overbaking will lead to a tough and dry brownie.
My Mom's Tip: Slice with a plastic knife for perfect cuts every time (plastic is naturally nonstick).
