Preheat the oven to 350°F. Line a cookie sheet with parchment paper or a silicone baking mat. Set aside.
With a mixer, cream together the peanut butter, butter, white sugar and brown sugar until blended.
Beat in the egg and vanilla until combined.
Next, add flour, baking powder and salt to the peanut butter mixture and mix together. The dough will be very soft.
Scoop tablespoonfuls of dough and roll into balls. Press a tsp measuring spoon into the center of the cookie dough to create a crater.
Place cookies 2 inches apart on parchment lined cookie sheets. Bake for 8-10 minutes. Don’t overcook! These cookies are much better soft and just barely cooked all the way through.
Allow the cookies to cool for 5-10 minutes on the pan.
After the cookies have cooled slightly, press a tbsp measuring spoon into each crater.
Let the cookies cool completely and spoon or pipe the Nutella into the center of each cookie. Enjoy!
