Cut sweet potatoes in half and roast at 400 degrees for 30-40 minutes, or until soft. Mash with a fork or a food processor. I added a tad of milk to my food processor to get them fully mashed. (Do this a day ahead to save time.)
Mix 2 cups of mashed sweet potatoes, milk and honey.
In a separate bowl, whisk whole wheat flour, baking powder, cinnamon, and salt together.
Using a cheese grater, grate 5 tbsp of butter into the flour mixture.
Fold the sweet potato mixture into the flour mixture.
Place the dough on a flat and floured surface. Pat or roll to 1-1.5 inches tall. Use a biscuit cutter to cut biscuits.
Place in oven at 400 degrees and bake for 10-12 minutes.
(Or freeze on a tray and bake at your convenience)
Serve with your favorite jam or honey!
