Set a large heavy skillet over medium heat and add the oil. Once the oil is hot, but not smoking, add the garlic cloves. Stir and fry for about one minute, until they start to gain color. Add the chipotle chiles and peanuts, stir and fry for about two minutes. Add the sesame seeds, stir and continue to fry for about a minute. Remove from heat. Carefully transfer all the contents from the skillet into the jar of a blender. Let cool for about 10 minutes.
