Preheat oven to 350 degrees F. Line a baking sheet with parchment paper.
In a medium bowl, whisk together the flour, baking powder, baking soda and salt.
In a large bowl, cream together butter, Nutella and the sugars until mixture is fluffy. Beat in the egg, followed by the vanilla extract.
Working at a low speed or by hand, gradually blend in the flour mixture and the oats (if you don’t have quick-cooking, pulse whole rolled oats in the food processor to chop them up a bit).
Drop teaspoonfuls of the batter (1/2-inch balls) onto prepared baking sheet, leaving at least 2-inches between cookies to allow for spread.
Bake for 10 minutes, until cookies are set.
Cool on baking sheet for 10 minutes, then transfer to a wire rack to cool completely.
Store in an airtight container.
