Chocolate-Plazma Roll Cake

Who says a roll cake can't be made like a torta? With the same filling and a fantastic flavor, this chocolate-plazma roll is just as delightful as a cake, and once you taste it, you won't stop at one slice! It’s so good, you’ll be running around for the rest of the day just to burn it off. Here’s how to make it:

Ingredients:

For the Sponge Cake:

• 7 eggs
• 7 tablespoons sugar
• 5 tablespoons flour
• 2 tablespoons cornstarch (if you don’t have cornstarch, use 7 tablespoons of flour)
• 2 tablespoons cocoa powder
• ½ teaspoon baking powder

For the Filling:

• 1 package of ground Plazma biscuits
• 200g powdered sugar
• 3 packets of vanilla sugar
• 600g sour cream (or "kajmak" in some regions, or Schmand in Germany)
• 3 packets of powdered whipped cream
• 325ml milk

Directions:

Make the Sponge Cake:

1. Beat the egg whites and sugar together until stiff peaks form.
2. Gradually add the egg yolks, one at a time, while continuing to mix.
3. Sift together the flour, cornstarch (or extra flour), cocoa powder, and baking powder, and gently fold it into the egg mixture using a spatula.
4. Pour the batter onto a baking tray lined with parchment paper, spreading it evenly.
5. Bake in a preheated oven at 170°C (340°F) for about 10 minutes or until the cake is firm and springs back when touched.
6. Once baked, turn the cake out onto a kitchen towel, remove the parchment paper, and roll it up carefully while it’s still hot. Let it cool completely.

Make the Filling:

1. In a bowl, mix the sour cream with the powdered sugar and vanilla sugar.
2. Add the ground Plazma biscuits, saving a couple of tablespoons for decoration, and mix until everything is well combined. Set aside.
3. In a separate bowl, whip the milk and powdered whipped cream until stiff peaks form. Reserve 6 tablespoons of the whipped cream for decoration.
4. Gently fold the whipped cream into the Plazma mixture, ensuring everything is smooth and well mixed.

Assemble the Roll Cake:

1. Unroll the cooled sponge cake and spread most of the filling evenly over the surface, leaving a little space on the edges.
2. Spread the whipped cream over the filling and smooth it out.
3. Carefully roll up the cake, gently pressing as you go to ensure it holds together.
4. Place the roll onto a serving plate, with the seam side down.
5. Take the reserved whipped cream and place it in a piping bag to decorate the roll as desired.
6. Dust the top of the roll with the remaining ground Plazma biscuits using a sieve for an even coating.

Enjoy this delicious and creamy roll with a cup of coffee or tea, and don’t worry if you’ve had a few slices—you’re allowed! Just make sure to savor the flavor!
