Cinnamon Yam Biscuits

This is actually off of a recipe card from Walmart. I like this recipe better than other versions I've tried. I'm pretty sure regular salted butter has about 1/2 t. of salt in it, maybe it has more. Anyway, I think I just used regular butter and omitted the extra.

2 c. flour

2 T. sugar

4 1/2 t. baking powder

1/2 t. salt

1/4 t. cinnamon

1/8 t. allspice

1/2 c. unsalted butter, cut into small pieces

1 c. mashed cooked yam

6-7 T. milk, or more as needed

Combine dry ingredients and mix. Cut in butter until crumbly. Beat yam and milk together and stir into flour mixture. Add more milk if needed to form a soft dough. Roll or pat 3/4" thick and cut into circles. Bake 18-21 min or until golden brown at 425.
