Preheat oven to 350°F. Line a 12-cup muffin pan with foil baking cups, or spray it with nonstick spray.
In a large bowl, combine all meatloaf ingredients. Thoroughly mix.
Evenly distribute meatloaf mixture among the muffin cups, and smooth out the tops with the back of a spoon. Bake until firm and cooked through with lightly browned edges, 20-25 minutes.
Meanwhile, bring a medium pot of water to a boil. Add potatoes, and once returned to a boil, reduce heat to medium. Cook until very tender, 15-20 minutes.
Drain and transfer potatoes to a large bowl. Add remaining ingredients for mashies except paprika. Thoroughly mash and mix.
Evenly top mini meatloaves with mashies, and sprinkle with paprika. Makes six servings; two cupcakes per serving. Eat up!
