A cake made with Greek yogurt and sweet potatoes.
Mash the steamed sweet potatoes.
Mix Greek yogurt into the mashed sweet potatoes (Use 200g Greek yogurt for 2~3 sweet potatoes. The batter should be thick and firm.)
Place the prepared batter into a dish or mold that fits the air fryer, or shape it nicely on parchment paper.
Bake in the air fryer at 170°C (340°F) for 45 minutes.
(For even better taste, let the baked cake chill in the refrigerator for about half a day before serving!)
