Powder the sugar and set aside 2 tbsp heaped. Warm the milk and stir in the coffee powder.
Sieve the remaining sugar powdered along with all-purpose flour, salt, baking powder and cinnamon powder. Add the beaten egg, vanilla essence and melted butter and fork it together.
Slowly pour in the coffee mixing the dough till the desired consistency is obtained. Do not add the coffee at one go as it may get too watery and may not hold together. You should be able to make a ball out of the dough kneading it for about 5 minutes.
Place the dough in a well-greased bowl and let it rest covered for about an hour.
Make smaller balls out of the dough and roll it out to about 1/2 an inch thick using a roller. Using a cookie cutter (bottle caps also work just as well) cut out large circles and using smaller cutters, cut out smaller concentric ones at the center and remove the excess dough at the center.
Heat the oil in a pan. Fry the doughnuts on medium flame till you attain the delightful brown color you want. Transfer it onto a towel for draining off excess oil.
Add a half a tsp of cinnamon powder and 2 tbsp of powdered sugar into a ziploc cover. Transfer the fried doughnuts into this bag and give it a good shake to ensure that all the doughnuts are coated well in the mix.
