Perfect for Nutella fans!

Ingredients:

• 1-2 tablespoon Nutella
• 1 cup water

Place the Nutella and water in a sauce pan.  Heat on medium stirring until the Nutella is dissolved.  Bring to a boil. Pour into your favorite mug and top with whipped cream and chocolate shavings or marshmallows.

Variations:

Microwave method:
Pour water/milk into microwavable cup and heat for 2 min.  Add Nutella and microwave for another minute. (Ezara mentioned below that if you have a higher power microwave these times are a bit high; try heating the water for 1 minute, add the Nutella and heat for another 40s). Stir and serve.

Make it creamier:
Replace all or part of the water with milk/cream.  Stir/whisk constantly while heating. Froth up the milk if you have a frother.

Make it more chocolaty:
Add 2 tablespoons of cocoa powder.

Make it spicier:
Add a pinch (or more) of cayenne pepper and/or a teaspoon of cinnamon.

Make it more caffeinated:
Add a 1/2-1 teaspoon instant espresso powder or replace some of the water with brewed espresso.
