Break the hardened glycerin into 1x1 inch squares.

Melt the glycerin at 30-second intervals in the microwave or over a double boiler, stirring after each interval.

Ensure the glycerin is fully melted but not boiling.

Stir in the honey and cinnamon.

Pour the mixture into soap molds to your desired thickness.

If you want oatmeal only on the top, stir it in and let it settle while the soap is still thin.

If you want oatmeal evenly distributed, wait until a layer forms on top and the mixture begins to thicken.

Remove the top layer with a spoon and slowly stir in the oatmeal, one teaspoon at a time.
