Cut the sweet potato into cubes. Boil 1 cup of cubed sweet potato in water until soft (approx. 20 minutes).
In a bowl, mash the cubed sweet potato and add the plant-based milk, maple syrup, and canola oil. Give it a quick whisk.
Add the flour and baking powder to the wet ingredients. Whisk until incorporated. Fold in the chocolate chips. Let the batter sit for a few minutes.
Spray a flat pan or griddle with oil and heat it up to medium to low heat. Add a small ladle of pancake batter*. Let it cook until the middle becomes bubbly and the corners set, then flip with a spatula. Let it cook on the other side until done. Repeat for all the pancakes. You should be able to get 8 pancakes out of the batter.
Stack the pancakes and drizzle with maple syrup. Enjoy!
*If the batter spreads too much in the pan, whisk a bit more flour into the batter. If it doesn't spread enough, add a bit more plant-based milk.
