Preheat the oven to 350 degrees.

Place the ham flat side down in a baking dish or high sided baking pan, and cover loosely with tin foil. Cook according to package directions until there are 30 minutes of cook time left, then remove.

When the ham has almost 30 minutes of cook time left, melt the butter in a saucepan over medium heat on the stove.

Add the brown sugar, cinnamon and ginger paste to the melted butter, and whisk until the sugar substitute is completely dissolved.

Continue to cook the mixture for another 2-3 minutes.

Remove the ham from the oven, remove the tin foil, and baste the ham with the brown sugar mixture.

Place the ham back into the oven and bake for an additional 20-30 minutes.

Remove the ham from the oven at the end of the cook time, baste with the extra glaze and juices in the pan and serve.
