Chocolate Chip Nutella Stuffed Cookies

When stressed, I tend to bake- and by bake I mean I make loads of cookies. I keep seeing Nutella cookies and I happen to love one certain chocolate chip recipe, so I thought why not combine it? Cook's Illustrated produces perfect products, which I often refer to for a multitude of recipes as well as refer to for various cooking techniques. They recipe-test multiple times and truly have created an incredible chocolate chip cookie recipe. I've adapted the recipe a bit, but the original link is here:
 Cook's Illustrated Perfect Chocolate Chip Cookies

Servings: About 24 cookies

Ingredients:

1 3/4 Cups All-Purpose Flour
1/2 Teaspoon Baking Soda
1 3/4 (14 Tablespoons) Sticks of Unsalted Butter
1/2 Cup of Granulated Sugar
1/2 Cup of  Brown Sugar
1 Teaspoon Salt
2 Teaspoons of Vanilla
1 Large Egg
1 Large Egg Yolk
1 1/4 Cups of Semi-Sweet Chocolate Chips
Nutella

Directions:

Preheat oven to 375 degrees.

Place Butter into a pan on the stove. Melt the butter and allow it to brown.

In a bowl combine the sugars, egg, egg yolk, vanilla, and salt.
In a separate bowl mix the flour and baking soda together.

Take the browned butter and add it to the sugar mixture. Whisk well to get out all of the lumps.
Slowly add a small amount of the flour mixture and stir. Continue this until all of the flour and baking soda mixture is incorporated into the sugar mixture.

Allow the dough mixture to cool for five minutes.
Then add the chocolate chips. (The mix needs to cool, otherwise the chocolate chips wil melt from the hot butter.)

Take a spoonful of cookie dough and flatten with your palms. Then place a small dollop of Nutella (1/2 teaspoon approximately) in the middle of the dough. Then fold over the cookie sides to cover the Nutella and form a small ball.

Place the cookie balls on a parchment lined baking sheet and bake for about 10-14 minutes, or until the cookies appear golden brown.
Allow cookies to cool then move to a wire rack and allow the cookies to completely cool.
