First make the pudding.
Mix cold milk with powdered pudding and sugar.
Mix everything and put on fire to cook until thick.
If you don't have blueberry pudding, take a regular one, and then add blueberry puree, 50g for example.
Well, in General, look at the color saturation.
So boil our pudding, remove from heat, cover with film and put to cool.
I put it in cold water. We're gonna need a little warm pudding.
Make the dough.
Divide the eggs into yolks and whites.
Eggs whites whisk until peaks.
Whisk the yolks with the sugar until white.
Add oil and water.
Next, add the flour with baking powder and vanilla.
Add our eggs whites.
And gently mix everything.
1/3 of the dough is poured into another bowl and add cocoa.
Take the form of 24 to 35 cm.
Lay the paper, pour the light dough.
And dark dough pour on top of chaotically.
On top then spread with a spoon our pudding.
Take the floor spoon.
Put in the oven to bake at 160 gr 30 minutes.
But look at your oven.
Maybe you'll need more time.
The cake should be browned.
Ready cake take out and let cool completely.
Sour cream mix with powder and vanilla sugar.
(I do this when baking cake, mix the sour cream with sah. powder and put in the fridge.)
Pour in the cooled cream.
Level and give him more to stand in the refrigerator.
You can sprinkle with grated chocolate.
Or pour over the chocolate. Better if kuhen will stand up night.
A delicious cake, especially if the refrigerator is now in the heat...
