Season the chicken on both sides with garlic powder, chili powder, paprika, salt, and pepper.
Heat a nonstick pan over medium heat. Once hot add the oil. Brown the chicken on both sides and cook to an internal temperature of 160 degrees using a thermometer. Remove from the pan and set aside.
For the mole sauce: In the same pan whisk together the broth, chipotle sauce, cumin, cocoa powder, lime juice, and tomato paste. Simmer, stirring occasionally until the sauce becomes thick and rich.
In a bowl whisk the sour cream and lime juice. Season with salt and pepper to taste.
Spoon the mole sauce and crema over the chicken. Garnish with red onion, cilantro and lime wedges. Serve with bread.
