Preheat oven to 375°F. Line a rimmed baking sheet with foil. Spray a six-cup muffin tin with nonstick cooking spray and set on top of the baking sheet.
In a large bowl, combine ground turkey, olive oil, quick oats, garlic powder, and freshly ground black pepper.
In a 1-cup measuring cup, measure out barbecue sauce, ketchup, and Worcestershire sauce; stir well. Pour half of the barbecue sauce mixture into the ground turkey mixture and mix to combine.
Evenly divide the meat mixture between the six muffin cups, smoothing the tops of the mounds. Carefully spoon the remaining barbecue sauce mixture over the meatloaf muffins. Bake for 30 to 45 minutes, until the center of a meatloaf muffin reaches 165°F on an instant read thermometer. Use a spoon to help lift the muffins out of the pan and drain on a paper towel-lined plate.
The baking sheet under the muffin tin is to prevent any potential overflow of ingredients from making a mess on the bottom of your oven.
