While meatloaf is cooking, mix all sauce/topping ingredients in a bowl with a whisk.
About 5-10 minutes before cooking is complete, spread sauce mixture on top of meatloaf with a basting brush, then allow it to finish cooking.
Let the meatloaf set for about 10 minutes before cutting to allow the juices to redistribute throughout the meatloaf.
