Preheat your oven to 375°F (190°C). Grease a muffin tin.
In a large bowl, mix together all the meatloaf ingredients until well combined.
Press the meatloaf mixture into the muffin tin cups, filling each to the top.
Bake for 20-25 minutes, or until the meatloaf is cooked through and the tops are browned.
While the meatloaf bakes, boil the potatoes in salted water until tender, about 15-20 minutes.
Drain the potatoes and mash them with milk, butter, salt, and pepper until smooth and creamy.
Once the meatloaf cupcakes are done, let them cool slightly and then remove them from the tin.
Pipe or spoon the mashed potato ‘frosting’ on top of each meatloaf cupcake.
Garnish with fresh chives or parsley before serving.
