Ingredients

For the cake:
  • 1 cup all-purpose flour/ plain flour.
  • ½ cup granulated sugar.
  • ⅓ cup Soft brown sugar.
  • ¼ cup Cocoa powder.
  • ½ teaspoon baking powder.
  • 1 teaspoon Baking soda/ Bicarbonate of Soda.
  • ½ teaspoon salt.
  • ½ cup hot coffee hot water with 1 tsp instant coffee.
  • ¼ cup cooking oil.
  • 2 small eggs see the note.
  • ½ cup milk see the note.
  • 1 teaspoon kashmiri red chilli powder optional (see the note).
For the frosting:
  • ½ cup Nutella see the note.
  • ⅔ cup Chocolate Chips.
  • ⅔ cup dark chocolate chips.
  • 1 ¼ cups heavy cream/ double cream.

Instructions

For the cake:
    Cup of Yum
  1. Grease two 8” baking pans and line with greaseproof paper/ parchment paper.
  2. Preheat the oven at gas 3.5/ 170° C/ 338°F.
  3. In a mixing bowl, place the flour, cocoa powder, granulated sugar, brown sugar, chilli powder (if using), baking powder, bicarbonate of soda and salt. Stir well using a hand whisk.
  4. Put the milk, oil and eggs in a measuring jug. Lightly beat it using a fork.
  5. Pour the egg mixture into the flour mix, and whisk it using a handheld blender, handheld mixer, or a hand whisk until you get a smooth thick batter.
  6. Then, add the hot coffee into the batter and carefully mix again until the batter is smooth and slightly runny. 
  7. Pour the batter into the prepared pans and gently tap the pans against the kitchen worktop to get the batter surface levelled. 
  8. Bake in the preheated oven at gas 3.5/ 170° C/ 338°F for about 45 minutes or until a skewer comes out clean when you test the cake. 
  9. Once the cakes are fully baked, leave them in the pans for about 2 minutes. Then take them out of the pans and put them on a cooling rack to completely cool down.
For the frosting:
  1. Place the cream and the chocolate chips in a mixing bowl. 
  2. Then heat the bowl in a microwave at high-heat (700-800w) for about 1 minute. Give it a good stir. You can see that the chocolate is melting. Mix it until you get as many chocolate chips melted as you can. Heat it again for about 30 seconds if it’s not fully melted. And stir well. 
  3. Or, you can melt the chocolate and cream on a double boiler. Just boil some water in a pot and put the mixing bowl over the boiling water. Let the hot steam melt the chocolate. Stir well until chocolate and cream are mixed thoroughly into a smooth chocolate ganache. 
  4. Leave the chocolate ganache to cool at room temperature. 
  5. Using a hand-held mixer or a stand mixer, whisk the chocolate ganache until you get a smooth and shiny chocolate mousse. Keep it in the fridge to slightly firm. You want the texture to be soft and spreadable. But not hard nor runny. 
To assemble the cake:
  1. Sandwich the cakes with Nutella.
  2. Spread the chocolate mousse to cover the cakes. 

Notes

  • The eggs weigh differently. So for this recipe, we need something around 110-120 grams of eggs in total (with the shell). 
  • We always use whole milk in our household, so that’s the milk I often use for this recipe. But if you want, you can use semi-skimmed or skimmed milk. 
  • Add the chilli powder if you prefer the spiced-up version of this chocolatey treat. A teaspoon of Kashmiri chilli powder will only give you a richer taste in the chocolate without any heat at all. But of course, you can always omit this and still make an irresistible chocolate cake.
