Preheat oven to 375°F. Line baking sheets with parchment paper.
In a large mixing bowl, beat butter, brown sugar and granulated sugar until creamy. Add in 1 egg and molasses and mix until combined.
In a separate bowl, whisk together flour, baking soda, salt, cinnamon, ginger, and cloves. Add flour mixture to the creamed butter. Mix just until combined. Stir in the rolled oats.
Scoop dough onto the prepared baking sheets by rounded tablespoon. Be sure to leave 2” between each. Bake for 8-10 minutes or until edges are browned and centre’s look slightly underdone. Allow to cool on baking sheet for 2 minutes before transferring them to a cooling rack.
