Preheat the oven to 375℉ & line a half sheet pan with parchment paper
Combine the plant milk with the vinegar & then add the sweet potato puree & whisk to combine
In a large mixing bowl combine the flour, baking powder, salt, cinnamon & nutmeg. Sift or whisk to combine evenly
Using a box grater shred the cold vegan butter into the flour mixture then using your hands work the butter through the flour until it is evenly distributed
Pour the milk / sweet potato mixture into the flour mixture & mix by hand until it forms a soft dough
Form the dough into a disc about 8" diameter on a lightly floured surface and cut it into 6 equal triangles OR using a 2 ounce scoop place the dough onto the parchment lined sheet pan spaced 2" apart then lightly press each on to form a disc rather than a mounded dough (this recipe makes about 12 small biscuits or 6 large triangle cuts)
Optional sprinkle each one with cinnamon sugar & bake in the preheated 375℉ oven for 15 minutes until light golden for the small ones & about 20-25 minutes for the larger triangle ones
