1 large sweet potato, baked, peeled and mashed
1 1/2 cups all-purpose flour (may substitute whole-wheat)
1 egg
1/4 cup rolled oats
1/4 teaspoon cinnamon

Mix all the ingredients together and knead a few times. Roll dough into a thick sheet and cut out desired shape of biscuits.

Arrange biscuits on a baking tray lined with parchment paper and cook in a preheated, 350-degree oven for 30 minutes, until crunchy and golden-brown.

Store them in an airtight container or sealed jar for up to 2 weeks.

Makes 1 dozen biscuits.
