Preheat oven to 350 degrees and line a baking sheet with parchment paper.
In a medium bowl (or using a stand mixer), add the nutella and egg. Cream together until combined. Add the flour and mix until combined. Stir in the chocolate chips. The batter will be stiff.
Take about 1 1/2 tablespoons of dough and wrap around a cherry forming a ball. Basically, you want to use as little dough as you can while covering the cherry completely. Repeat with remaining dough.
Bake for 10-12 minutes or until dough is not wet. Let cookies cool on the pan as they will continue to bake there. If you like yours extra gooey try baking for less time (8-9 minutes). It will all depend on how big you make your cookies.
Notes
Make sure when you are measuring your flour that you spoon the flour into the measuring cup. If you scoop your flour using the measuring cup you will be packing the flour in and overmeasuring causing your cookies to be dry.
