Over medium-high heat in a large Dutch oven or stock pot, toast the dried chiles until fragrant, about two to three minutes. Add 2 cups beef stock and bring the mixture to a simmer. Cover, reduce heat and continue to simmer for 10-15 minutes until the chiles soften and are pliable.
Add the chiles and beef stock used to simmer the chiles to a blender with the chipotle peppers and adobo sauce. Blend until smooth. Set aside the chile paste.
Heat oil in a large, heavy-bottomed stock pot or Dutch oven over medium heat. Add the onion and jalapenos to the pot. Cook until softened, about four to five minutes. Add the garlic and cook for 30 seconds, stirring constantly.
Add ground venison to the onion mixture. Cook the venison until it browns, using a wooden spoon to break up the meat as it cooks.
Pour in remaining 4 cups of beef stock, strong coffee and reserved chile paste, scraping up the bottom of the pot with a wooden spoon.
Stir in the Rotel tomatoes, tomato paste, apple cider vinegar, cocoa powder, brown sugar and spices. Bring the heat back to medium-high and boil the mixture.
Once it boils, reduce the heat to a simmer. Put the top on, leaving a small crack open. Simmer for two to two and a half hours while stirring occasionally.
In the last 10 minutes of cooking, add beans. Turn off heat. Serve with desired toppings. Enjoy!
