Preheat your oven to 325 degrees.

In a small bowl melt your butter and whisk in the honey and dijon until all combined.

Place your ham in a large baking dish.

Coat the ham in the honey butter mixture.

Next in another bowl combine the onion powder, paprika, pumpkin spice and both sugars.

Using your hands coat the outside of the ham with about half of the sugar mixture.

Cover with foil and place in the oven and bake for about 2 hours or until 130 degrees.

Remove the ham from the oven and carefully coat the ham with the rest of the sugar mixture.

Turn the oven up to 425 degrees and place the ham back in the oven for 10-15 minutes just until the sugars caramelize a bit.

Slice and serve!
