Ingredients taken is based on a great shape, size 30x30 (the output is big, 16-20 portions).

Package BlackBerry (or any other frozen berries), pre-thaw.You can take canned cherries (compote pitted, will be even tastier!).And you can take and fresh, but in addition how expensive cherries, berries is not observed!

then in a large enough container, beat with a mixer: - 1 Cup flour - 1 Cup sugar - 1 Cup cocoa powder (1/2 of cocoa+1/2 sugar if you take Nesquik, 1 Cup only it) - 1/2 Cup sunflower oil without smell - 3 eggs - 1/2 Cup sparkling mineral water 1 sachet baking powder - if so, ground walnuts (but without them well) and immediately pour into a greased baking pan (the output is large, so that the form doesn't save, take a little wider, 30x30 - no less)

and decorate with berries (spread slightly pressing it into the batter)

bake in preheated oven for 35-40 minutes (readiness is checked with a match or toothpick, if dry - remove, do not tumble dry)

can sprinkle with powdered sugar, like I did (on the advice of OIGAS), and you can pour the syrup. Syrup: 2 tablespoons lemon or orange juice (from bag) + 4 tablespoons of sugar. Boil briefly in a small cezve (prior to thickening) and evenly pour on the still hot cake. Flavor! The structure is like a tender cupcake, with a pronounced chocolate-nutty taste, aromas of blackberries is not very noticeable, but the berries provide the juiciness. Very tasty and easy cake!
