Chocolate Base for Any Cake

Preparation

1. Preheat the oven to 180ºC. Melt the chocolate coating together with the butter over low heat until completely combined.
2. Allow the chocolate to cool to 35ºC before proceeding with the recipe. Separate the yolks from the whites of three of the eggs, placing each part in a separate bowl.
3. Add the white of the fourth egg to the bowl with the other three whites.
4. Whisk the four egg whites until they form stiff peaks, gradually adding the sugar until you achieve a firm and fluffy texture.
5. Beat the three egg yolks separately until they are well aerated and pale in color.
6. Gently fold the whipped yolks into the egg whites using a spatula, stirring with gentle folding movements.
7. Incorporate the melted chocolate into the egg yolk and white mixture, stirring until the mixture is homogeneous.
8. Line the base of the mold with parchment paper, ensuring it is well placed to prevent the cake from sticking, and fill the mold with the prepared batter.
9. Bake the cake at 180ºC for 20 minutes. Check the doneness with a toothpick; if it comes out clean, the cake is ready.
10. Preheat the oven again to 170ºC for the second part of the recipe.
11. Melt the chocolate using a double boiler, ensuring that no water gets in, as this could affect its consistency.
12. Emulsify the butter until it is smooth and creamy. Add the muscovado sugar and a pinch of salt, and stir until well combined.
13. Gradually incorporate the eggs, ensuring each addition is well mixed before adding the next.
14. Add the melted chocolate, prepared in a bain-marie, when it reaches approximately 38ºC, pouring slowly while stirring constantly.
15. Gently fold in the sifted flour and cocoa powder, stirring softly until the mixture is homogeneous.
16. Finish homogenizing the mixture using a spatula, ensuring there are no lumps.
17. Place parchment paper on the bottom of the mold and fill it with the resulting mixture.
18. Bake at 160ºC for about 20-40 minutes, checking the doneness with a toothpick inserted into the center of the cake, which should come out clean when it is done.
