Healthy Benefits
Although the cake isn’t healthy, pumpkin, including canned, is a great source of beta-carotene, the vegetable pigment that the body turns into vitamin A. Pumpkin also contains a hefty amount of fiber, ample amounts of iron, and vitamin C. Using a combination of sugar and sugar substitute in the glaze cuts the sugars and carbs down but doesn’t compromise the taste at all.

Instructions

To make the glaze:
- Place the sugar, sugar substitute, buttermilk, light butter, baking soda, and vanilla in a small saucepan and heat over medium heat.
