How to make triple chocolate cake step by step

Step 1 - preparations

• Grease the baking pan with butter and dust with flour, or line with baking paper.
  
• Preheat the oven to 170℃ (fan-assisted) or 180℃ (top/bottom heat mode).
• Sift together flour, cocoa, and baking powder through a fine sieve.
  250 g wheat flour, 30 g cocoa, 2 teaspoons baking powder
  

Step 2 - preparing the chocolate cake

• Transfer the wet ingredients for the cake and sugar to a large bowl.
  4 eggs, 250 g sugar, 200 ml milk, 160 ml oil
  
• Mix everything together with a kitchen whisk or a spoon.
• Add the sifted flour with cocoa and mix until combined.
  
• Pour the batter into the prepared pan.
  
• Place the cake in the preheated oven and bake for about an hour - until a dry skewer comes out clean.
• After baking, let the cake cool completely.

Step 3 - preparing the chocolate cream

• While the cake is cooling, heat the heavy cream in a saucepan until hot, then add the broken chocolate and mix thoroughly until you get a smooth chocolate mass. Let it cool.

• To the cooled chocolate mixture, add mascarpone cheese and blend briefly until just combined (you can also mix the cream with a whisk if you don't want to use a mixer).

Step 4 - assembling the chocolate cake

• Cut the chocolate cake into two layers.
  
• Place the bottom layer on a plate and secure the baking pan ring around it.
  
• Spread the chocolate cream over the cake and level it.
  
• Carefully place the top layer of chocolate cake on the cream.
  
• Refrigerate the cake for at least an hour for the cream to set.

Step 5 - preparing the chocolate glaze

• Break the chocolate into pieces, add the heavy cream to it and heat together until melted - I heated them together for 30 seconds in the microwave. Mix thoroughly.
