Add steamed sweet potato and the cooked or canned black beans in a mixing bowl. Make sure you pat the beans dry and remove the excess moisture.
Mash the beans and sweet potato using a potato masher. To this add finely chopped onions, Chopped cilantro. Also, add minced ginger and minced garlic.
Add the spice powders and salt. I am using Garam Masala, Coriander powder, and Cumin Powder.
Next, add the Oats Powder.
Combine everything together and bring it as soft dough. refrigerate it for 30 mins.
Divide the patties into equal portions. Pinch in part and shape them as patties. Shape the patties with all the dough and arrange them in a baking tray. Freeze them for 15 mins.
Air Fryer Method:
Preheat the air fryer to 200 C / 400 F for 5 mins. Spray in some oil and arrange the patties. Air fry at 180 C / 356 F for 12 mins. Flip once halfway and brush with oil as needed.
Stovetop Method:
Heat a cast iron pan with oil. Once the oil is hot drop in the patties and shallow fry in a medium flame.
Flip and cook both sides until the patties are crisp and golden.
Drain in paper towels once they are cooked
