Bake bacon in the preheated oven until partially cooked but still flexible, 6 to 8 minutes.
Brush venison tenderloins with olive oil and season with onion powder, salt, and black pepper. Place tenderloin roasts side by side and wrap them together in strips of partially cooked bacon. Place into a roasting pan.
Roast until bacon is browned and an instant-read meat thermometer inserted into the thickest part of a tenderloin reads at least 145 degrees F (65 degrees C), about 1 hour.
Heat butter in a saucepan over medium heat; cook and stir mushrooms and garlic in hot butter until mushrooms are soft, 8 to 10 minutes. Stir green onion into mushroom mixture; pour in cream. Cook, stirring often, until sauce is heated through. Serve sauce with tenderloins.
Mix together venison, 1 tablespoon brown sugar, crackers, and egg in a bowl. Season with mustard, cilantro, garlic powder, onion flakes, thyme, cinnamon, and paprika; mix well. Pat mixture into a 9×9-inch pan, or a loaf pan.
Bake in preheated oven to an internal temperature of 160 degrees F (70 degrees C), about 40 minutes. Stir together the ketchup, with 1 tablespoon brown sugar. Spread on top of the meatloaf, and place back in the oven for 10 minutes more.
Place chunks of venison into a shallow baking dish, and pour enough apple cider in to cover them. Cover, and refrigerate for 2 hours. Remove, and pat dry. Discard apple cider, and return venison to the dish. Pour barbeque sauce over the chunks, cover, and refrigerate for 2 to 3 more hours.
Preheat an outdoor grill for high heat. Charcoal is best, but if you must, use gas. Remove meat from the refrigerator, and let stand for 30 minutes, or until no longer chilled. Wrap each chunk of venison in a slice of bacon, and secure with toothpicks.
Brush the grill grate with olive oil when hot, and place venison pieces on the grill so they are not touching. The bacon will kick up some flames, so be ready. Grill, turning occasionally, until the bacon becomes slightly burnt, 15 to 20 minutes. The slower, the better. Dig in, and prepare to want more!
