Marshmallows, chop into small pieces. I used pink marshmallows, but white, pink and white, but not chocolate because the extra chocolate in the test violates the proportion of dry and wet ingredients.

Prepare the dough for the pie. Butter room temperature vzbit with sugar with a mixer for 5 min.

Add the egg, again beat well.

Then pour the sifted flour, baking soda, cocoa powder, vanilla sugar, stir with a spatula.

To connect the resulting mass with marshmallows, dough vescovato, not a liquid, it takes on the spoon full.

The bottom of a split form lay baking paper or silicone Mat. If you use baking paper, I recommend oiling it is not a large amount of vegetable oil. I have a square 20x20 cm, you can not take a large round shape. And so, the finished dough is distributed on the form.

Prepare the protein mass - chilled proteins vzbit with sugar to hard peaks.

Black currants (I had frozen, not thawed) mix with starch. I tried to bake a pie with fresh berries, tasty, but I liked it more with the frozen berries remain whole, not flattened. And so, black currants spread on the dough and distribute proteins throughout the surface of the cake. Bake in a preheated to 180 With the oven for 20 minutes, and then under the top grill for 2 minutes to obtain a "sunburn" on the protein cream. If the baking process is a protein tip has acquired a "tan", it is not necessary to bake it further. The finished cake to cool in shape very WELL! The cake has to rest, okay to cool at room temperature.

When the cake is cold cut it into pieces.

Pie is not the usual taste, in my opinion, take one bite and it combines the lightness and viscosity of marshmallow, black currant berries impart a tangy acidity and surprisingly, the cake, in the presence of a marshmallow, soft and airy!
