Orange and cinnamon cake

First time I made this cake without consulting any recipe, but vaguely remembering that I had made something similar in the past. It turned out so well, I thought I'd write down the recipe next time, if I ever manage to reproduce it. I did reproduce it, so here is the recipe:

Ingredients, in order of appearance:

teaspoonful orange zest
juice of one orange (measured, it amounted to about 100 ml)
2 eggs, medium
1/2 teaspoonful salt
3/4 cup* white sugar
teaspoonful cinnamon
60 ml sunflower oil (refined, so it doesn't smell of anything much; can easily be replaced by other refined non-smelly oil)
100 ml milk
1 and 1/2 half cups plain flour (approx)
teaspoonful baking powder

pancakes

There is a lot of recipes for pancakes around, and I experiment periodically, though I still can't recreate the taste and general feel of the thick pancakes ("оладьи") of my childhood. I suspect it is mostly due to the fact that dairy products are different everywhere, and some of the stuff readily available in Russia ("кефир", for example) is not so readily, and sometimes not at all available where I live.
