In a large bowl, whisk together the dry ingredients (oats, flour, baking powder, baking soda, cinnamon, cloves (if using), salt.
In another mixing bowl, stir together butter vanilla, both sugars and egg. Stir until well combined.
Add the wet ingredients to dry ingredients and stir until combined. The dough will be sticky.
Add chocolate chips and M&M candy and mix in well.
Cover the bowl with saran wrap and place in fridge for at least 2 hours to overnight.
When ready to bake, line baking sheet with parchment paper or silicone baking mat.
Preheat oven to 350 degrees F.
Scoop the dough with medium size cookie scoop (1 and ½ Tablespoon size). Place scoops of dough on prepared baking sheet, spacing them 2" apart. Add few chocolate chips and M&M's on each scoop, if desired.
Bake cookies for 13 to 15 minutes. For me 14 minutes was the magic number.
Let cool on sheet for 5 minutes, then transfer onto cooling rack.
Notes
You can use any chocolate chips you like.
You can press the cookie dough into an 8" square baking pan and bake it for 18 to 20 minutes to make cookie bars.
