2. Add mashed sweet potato, banana, dates, applesauce, water, balsamic vinegar, and vanilla to a high speed blender and blend until smooth, several minutes.
3. In a large bowl, add the oat flour, cocoa powder, baking soda, and baking powder, and mix together. Add the wet ingredients to the dry and mix together until smooth. The batter will be thick.
4. Divide the batter between the two prepared cake pans and spread it out evenly.
