Step 1

Preheat oven to 350°.

Step 2

Cream together the butter, granulated sugar and brown sugar.

Step 3

Add the egg and vanilla. Mix until light in color and creamy.

Step 4

Add in the dry ingredients (flour, baking soda, baking powder and salt), mix into the dough. Mix until completely combined.

Step 5

Portion out the dough into a little less than 1/2 cup portions. Roll into a ball and arrange 6 onto each cookie sheet.

Step 6

Use your thumb to create a pocket into the middle of the dough. Spoon about 1/2 tbsp of Nutella into each pocket and then close the cookie around the Nutella. Flatten just slightly prior to baking.

Step 7

Bake for 12-15 minutes, until the cookies have spread and have started to crackle a little on top.

Step 8

Allow the cookies to cool on the pan for 10 minutes.

Step 9

Spoon the remaining Nutella into a zip top bag, snip the corner slightly and zig zag the Nutella across the top of the still warm cookie.

Step 10

Immediately sprinkle with sea salt. Serve warm.
