Preheat oven to 375°F and spray a muffin tin with non-stick cooking spray.
Mix ground beef, breadcrumbs, ketchup, Worcestershire sauce, ½ tbsp BBQ sauce, garlic powder, salt, and pepper in a large bowl.
Divide mixture among 8 muffin cups, pressing firmly and creating a slight depression in the center.
Brush remaining BBQ sauce over each meat cup.
Wrap each meat cup with a slice of bacon, tucking ends underneath.
Bake for 25-30 minutes until internal temperature reaches 165°F and bacon is crisp.
While baking, prepare mashed potatoes and transfer to a piping bag with a star tip.
Let meatloaves rest 5 minutes before removing from tin.
Pipe mashed potatoes on top in a swirl pattern to resemble frosting.
Garnish with chopped herbs and serve warm.
