Traditional mole sauce can take several days and nearly 30 different spices to cook properly. Fortunately for busy cooks, prepared mole sauce is available in most supermarkets. Mole sauce has a rich flavor most notable for containing a mix of chili peppers and dark chocolate. Jarred mole sauce is convenient but can be a little bland, so don't be afraid to spice up your chicken breast mole with whatever's handy in your spice rack.
Preheat your oven to 375 degrees Fahrenheit. Rinse the chicken breasts, and blot them dry with paper towels.
Coat a baking dish with a spritz of nonstick cooking spray to keep the chicken and mole sauce from sticking.
Place the chicken breasts into the baking dish in a single layer. Pour the mole sauce on top.
Bake the chicken for 30 to 45 minutes, or until inserting an instant-read thermometer into the center of the thickest chicken breast shows a temperature of 165 degrees Fahrenheit.
