Step 1

Preheat your oven to 350 degrees and line 2 cookie sheets with parchment paper.

Step 2

Whisk together your flour, oats, baking powder, baking soda, and salt. Set aside.

Step 3

Add your butter and both types of sugar to a large bowl and mix on medium speed until the butter is light and fluffy (about 3-5 minutes). Add the eggs and vanilla and continue to mix until they're thoroughly blended.

Step 4

Gradually add in the flour mixture (make sure each addition has been mixed in before adding more). Then add the hazelnuts and chocolate chips and fold them in with a wooden spoon.

Step 5

Measuring the dough with a tablespoon, drop the cookies onto the baking sheet 2" apart and bake for 15-18 minutes or until the edges have set. Cool the cookies for 5 minutes on the baking sheet, then transfer them to a wire rack to finish cooling.
