Nutella-Stuffed Chocolate Chip Cookies

0 Line a baking sheet with parchment paper.
1 Scoop teaspoon-sized dollops of Nutella onto the sheet and freeze for 20–30 minutes. (This makes stuffing the cookies much easier!)
2 Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
3 In a large bowl, cream together the butter, brown sugar, and granulated sugar until light and fluffy.
4 Add the egg and vanilla extract, mixing until smooth.
5 In a separate bowl, whisk together the flour, baking soda, and salt.
6 Gradually mix the dry ingredients into the wet ingredients until combined.
7 Fold in the chocolate chips.
8 Scoop about 2 tablespoons of dough and flatten it in your palm.
9 Place a frozen Nutella scoop in the center, then top with another small piece of dough. Seal the edges and gently roll into a ball.
10 Place the stuffed dough balls onto the prepared baking sheet, spacing them 2 inches apart.
11 Bake for 10–12 minutes, or until the edges are set but the centers still look slightly underbaked.
12 Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack.
