Add the chipotle peppers, spices, salt, vegetable stock, diced tomatoes, almond butter and tomato paste. Heat over medium-high heat until it begins to simmer, reduce heat to medium and simmer for 5 minutes.
Remove from heat and add the chocolate of choice, stir until completely melted and well blended.
Use an immersion blender to make sauce smooth. If you don't have an immersion blender use table top blender, puree/pulse the mole sauce in small batches as it will be hot.
Serve with roasted vegetables, rice, beans, or use as sauce for Oaxacan Mole Pot Pies (recipe coming soon).
