To start prepare all the ingredients! (there still needs to be soda and milk, sorry, I forgot to photograph them=) )

Pour the yogurt into a convenient container, add eggs, flour, baking soda, sugar and semolina. Cocoa and vanilla sugar until set aside aside) and mix. I use a mixer Dough consistency is obtained as for Charlotte, like sour cream I don't leave semolina to swell, cook immediately)

Then divide the dough into two parts, one part add 3 tablespoons cocoa and another whole bag of vanilla sugar (not vanillin)

Chaotic motion pour batter into the pan, I split 28cm. you can just pour in half, you can spoon, but you can as I am to draw patterns))) here as your heart desires (by the way, an important tip, before you pour the dough, brush the edges of a split form egg white in the places where I inserted the bottom and put it in the oven for two minutes, it will save your manna from flowing, especially if the form is eventually almost lost form and not so tight!)

Put in duhovochku for 30 minutes at 200 degrees ( well in my oven) ) you see yourself on the principle of "dry matches" I apologize for my oven=)

Now for the frosting, in an iron pan, connect oil (100 g), milk (4st. l), cocoa (6h. l) and sugar 8ст. l) I sugar ground in a coffee grinder but this is optional) Cook until liquid, about 10 minutes, set aside, give a little to cool

Get ready manna from the oven and allow him to relax a bit, it will help you easily pull it out of shape and have a smooth shape. Then spread on a plate and pour glaze

Well, here's the result: help yourself!) great warm and cold!
