In a large skillet over medium-high heat, brown the ground venison. Drain any excess fat.
Transfer the browned venison to the slow cooker.
In the same skillet, sauté the onions, garlic, and bell peppers for 3-4 minutes until slightly softened. Add to the slow cooker.
In a small bowl, mix all the homemade chili seasoning ingredients.
Add the seasoning mixture to the slow cooker and stir to combine with the meat and vegetables.
Add diced tomatoes, kidney beans, black beans, beef broth, and tomato paste to the slow cooker. Stir well to combine all ingredients.
Cover and cook on low for 6-8 hours until meat is tender.
Serve with your favorite chili toppings and enjoy!
Notes
You can cook on HIGH 3-4 hours instead. For a thicker chili, you can add a cornmeal slurry (2 tablespoons cornmeal mixed with 1/4 cup water) in the last hour of cooking.The cocoa powder in the seasoning mix adds depth to the flavor without making it taste like chocolate. Don't skip this ingredient!
