In a deep pot preheat oil over medium heat. If using a thermometer, heat oil to approx 325°F (160°C).
In a bowl, mix flour, baking powder, and sugar.
Grate approx. 1/2 teaspoon of nutmeg into the flour mix.
Fold in yogurt and press out large lumps of flour.
Fold in the vanilla extract.
Use the cookie dough scoop to portion one donut hole into the pot. If the dough begins to immediately sizzle, then the oil is ready for use.
Scoop in more donut holes until they just cover the top but still have space to flip over.
Fry on each side approx 3 minutes and then flip and fry for another 3 minutes or until golden brown on all sides.
Check for doneness by puncturing the center of one of the donuts with a toothpick. If the toothpick comes out clean, then the donut is cooked in the middle.
Remove the donuts from the oil and place them in a strainer or cooling rack to drain excess oil. Enjoy!
