Step 1

Separate egg whites from yolks. In a medium bowl, whisk together yolks, sugar and vanilla. Add flour until well blended.

Step 2

In a large bowl, beat egg whites on high-speed until they foam and are about 3-4 times in volume (about 2 1/2 to 3 minutes). Don’t beat too long or they will become too stiff and won't blend well.

Step 3

Use a spatula to gently fold the yolk mixture into the egg whites until well combined. Don’t mix too much or you will lose volume. The batter should have a fluffy texture.

Step 4

Divide the batter evenly among the two, lined cake pans & bake 20 minutes until the tops are golden.

Step 5

As soon as the cake is done, turn the cake out onto a clean surface and peel off the wax paper. This is much easier to do while the cake is still very warm.

Step 6

Use a knife to remove rough edges. Let cakes cool to room temperature.

Step 7

Place on of the cake layers into the bottom of a springform pan and pour 1/2 of your soda/syrup over the cake and let it soak in. (You will pour the ptichye moloko over this layer).

Step 8

In a small sauce pan, combine 1 packets unflavored gelatin with 1/2 cup milk.

Step 9

Whisk together over medium heat. Continue whisking until it just begins to steam, then remove from heat (DON'T BOIL).Set aside to cool.

Step 10

In the bowl of an electric mixer on medium speed whisk together 1/2 cup sugar, 8 oz tub of sour cream and a 8 oz tub of cool whip until well blended.

Step 11

With the mixer on, slowly add the warm milk mixture. Immediately pour over the first biskvit layer inside the prepared baking dish. Smooth the top as evenly as possible. Cover and refrigerate to cool.

Step 12

Freeze your mixing bowl and whisk attachment for 10-15 minutes before beating the cream and keep the heavy whipping cream refrigerated until you are ready to use it.

Step 13

Whip the heavy cream at high speed until it forms soft peaks (1 minute).

Step 14

Add the sifted powdered sugar and vanilla and continue whipping at high speed until the cream forms stiff peaks but is still smooth (about 1 minute).

Step 15

Place the second cake layer over the ptichye moloko and pour the rest of syrup/soda over the cake layer. Cut around the edges of the cake to loosen in from the springform pan.

Step 16

Trim the edges of the ptichye moloko to make it even with the cake layers.

Step 17

Frost the cake and even it out with a food-scraper.

Step 18

In a small saucepan, over low heat, melt 3/4 cup chocolate chips, stirring constantly until smooth.

Step 19

Transfer to a ziploc bag and cut a small hole on the tip. Practice a couple of strips on wax paper. Transfer the cake to your favorite cake stand. Refrigerate the cake until ready to serve.
