After you make these biscuits... you will never want to have plain biscuits again. They taste similar to the filling of a sweet potato pie, but not as sweet. If you are looking for sweeter biscuits, I would go ahead and double/triple the amount of sugar in the recipe and omit the salt in the water when boiling the potatoes.
1 large sweet potato (it should make about 1.5cups when mashed)
2.5 cups of Original Bisquick Mix
1 Tablespoon of Sugar
2 - 4 Dashes of Cinnamon
2 Tablespoons unsalted butter melted
Preheat the oven to 450 degrees.
Boil skinned and chopped sweet potatoes in lightly salted water. When chopping the sweet potato, it does not have to be neat since it will be mashed later. Once the potatoes are soft and can be easily mashed with a fork, drain water, mash the potatoes, and then set aside until cooled.
Once cooled, combine Original Bisquick Mix, sugar, cinnamon, melted butter and potatoes to form the dough. I also added a dash of Vanilla Soy Milk for good measure. The dough should still be wet and sticky, but firm enough to make drop biscuits in an oven pan.
In a lightly greased oven pan, spoon biscuits onto the pan and place into the oven. I made 8 good sized biscuits, but you could easily make more if you wanted smaller ones.
Bake for 16 - 20 minutes, or until a toothpick comes out clean when poked into the center of the biscuit.
Once removed from the oven, melt butter or margarine over the top and enjoy!
