Take a mixing bowl and add to it your pot of plain yogurt. Then, once rinsed out and dried, use it to measure 3 pots of flour and 2 pots of sugar and add this to the mix. Using a fork (or electronic whisk), mix the contents. Again, using the same yogurt pot, measure 1/2 pot of oil and 1/2 pot of milk and add to the bowl. Then, measure out the 1 tbsp of baking powder and crack to eggs into the batter. Mix (tilting the bowl and moving the fork in a circular motion to get as much air in as possible) until the mixture is nice and smooth, free from lumps. If there are any chocolate fanatics out there, you could swirl in some melted chocolate for a marble effect!
