Preheat the oven to 400 degrees.
Rinse and scrub the outer skin of the potatoes with a vegetable brush. Place the potatoes on a foil or parchment lined baking sheet. Poke the potato 3 to 4 times with a fork. Bake in the oven for 45 minutes or until easily pierced with the tip of a knife. Remove the potatoes from the oven and allow them to cool slightly before removing the skins.
Add the flesh from the sweet potatoes, milk, maca powder and cinnamon to a food processor. Blend until smooth and creamy, adding more milk if necessary.
Divide the sweet potato mixture evenly among bowls and top with desired toppings.
