Line 2 large baking sheets with parchment paper. Set aside.
In a medium saucepan set over medium heat, combine the butter, sugars, cocoa, and milk and bring to a boil, about 3-5 minutes.
½ cup unsalted butter, 1 cup granulated sugar, ½ cup brown sugar, ½ cup milk, ⅓ cup unsweetened cocoa powder
Remove the pan from the heat and add in the Nutella, vanilla, and oats.
½ cup Nutella, 1 teaspoon pure vanilla extract, 3 cups quick cooking oats
Stir the mixture until everything is combined well.
Scoop out the mixture (I like to use a ¼ cup cookie scoop) and drop them on the baking sheet.
Let the cookies set in the fridge for about 15 minutes before serving.
Notes
*You can use any type of cocoa powder you like for these cookies, as long as it is unsweetened. Use natural cocoa powder for a slightly more acidic taste, or use Dutch-process for a slightly smoother taste.**The Nutella can be replaced with the same amount of peanut butter or almond butter.Tips:
I use whole milk, but skim, almond or oat milk will also do the trick. Just use whatever milk best fits your dietary needs.
I topped my cookies with chopped hazelnuts and flake salt before placing them in the fridge to set, but that is completely optional!
Storage: Store Nutella no bake cookies in an airtight container in the refrigerator for up to 3 days or in the freezer for up to 2 months.
