In a small to medium sized saucepan, heat the olive oil over medium heat. Cook the chopped onions for a few minutes, until softened.
Then add the minced garlic and cook another minute.
Stir in the chili powder, cumin, cinnamon and salt. Toast for another minute, then remove from heat.
Transfer the mixture to the blender. Add the remaining ingredients. Blend until smooth.
Now pour the mixture back into the saucepan and cook over low heat until everything is hot. Taste and add more salt if needed.

This recipe makes about 3/4 cup of mole sauce. You can swap the brown sugar for maple syrup.If you want more heat, add another chipotle pepper to the sauce.If you don’t have a blender, a food processor or immersion blender can work well too.Store any unused sauce in an airtight container in the refrigerator for at least 5 days. Rewarm on the stovetop or microwave before use.
