Add the ground turkey, panko, parmesan cheese, onion powder, garlic powder, chipotle chili powder, and a pinch of salt into a large mixing bowl. Mix everything together thoroughly with your hands.
Roll the mixture into tablespoon-sized meatballs. Place them in your Crockpot in a single layer.
Pour the hot sauce and 1/4 cup water over the meatballs. Add the butter on top. Cover the slow cooker and set to low heat for 3-4 hours or high heat for 1-2 hours.
When the cooking time is up, turn the heat to high. Stir in the softened cream cheese and shredded cheddar cheese. Add the broccoli and gently mix. Cover and cook for an additional 15 minutes until the sauce is smooth and creamy.
Serve over rice or enjoy the meatballs straight out of the Crockpot with buffalo sauce or ranch for dipping.
