For the sauce:
Add all the sauce ingredients into a small bowl and whisk until just combined. Set in the fridge until serve.
For the cakes:
Preheat the oven to 200 C.
Wash and dry the sweet potatoes.
Place the sweet potatoes into an oven-friendly dish, cover with aluminum foil and bake until soft, for about 40 minutes. Let cool.
Peel the sweet potatoes, place them into a food processor and add all rest of the ingredients.
If you want a thicker consistency, you can add a little bit more flour.
Heat a skillet on low-medium heat and add coconut oil.
Cook the cakes using about 1 ice-cream scoop of the batter and a mason jar for the shape.
Cook on both sides until golden brown.
Serve with the yogurt sauce. Enjoy!
