Preheat oven to 425 degrees. Mix the mashed bananas, soymilk, and oil together in a large bowl. Add the flour and baking powder and stir well. 

Place dough on a floured surface and knead for 3 minutes. Using a rolling pin, roll dough to a 1/2-inch thickness. Cut into 2-inch-wide circles using a cutter or tin can. Place biscuits on a lightly oiled cookie sheet, bake 20 minutes or until browned. Serve warm.

These delicious biscuits make a perfect breakfast item.

Leftovers can be re-heated in a toaster oven.
