Preheat your oven to 375°F and line a sheet pan with foil or parchment paper. Brush the surface with olive oil to lightly coat it.
Make the buffalo sauce by stirring together the melted butter and hot sauce in a small bowl, then set aside.
Add all of the meatball ingredients, along with 2 Tablespoons of the buffalo sauce, to a large mixing bowl and mix until just combined. Do not overmix, or the meatballs will be too firm.
Use a small cookie scoop to scoop the meatballs onto the prepared sheet pan. They should be around 1 to 1½ tablespoons in size. Wet your hands and roll the meatballs in your palms to shape them into round balls.
Bake for 15-18 minutes, until the internal temperature reaches 165°F and the meatballs are lighty browned.
Toss the meatballs in the remaining buffalo sauce and serve.
Notes
Keep a bowl of water on the counter when rolling the meatballs to shape and dip your hands in the water when the meatballs begin to stick to your hands.
Store leftover meatballs in an airtight container and refrigerate for up to 4 days. Reheat in a 325°F oven until warmed through or in the microwave.
