Prepare the Cake:
Preheat your oven to 180°C (350°F).
In a large bowl, mix together the flour, brunette sugar, cocoa powder, honey, cinnamon, and baking powder.
Gradually add the milk, stirring until you have a smooth batter.
Grease and flour a 25 cm x 35 cm baking mold, pour in the mixture, and bake for 20 minutes, or until a toothpick comes out clean.
Allow it to cool completely before removing it from the mold and slicing it into two equal layers.
Make the Syrup:
Combine the milk, honey, nutmeg, and ginger in a bowl, mixing well until everything is blended.
Prepare the Filling:
In a separate bowl, beat the cold milk with sugar until it forms a firm texture, then gently fold in the dulce de leche until fully combined.
Assemble the Pavé:
Place one layer of the chocolate cake in a dish and moisten it with the syrup.
Spread a generous layer of the dulce de leche mixture over it.
Add the second layer of cake, repeating the soaking and filling process.
Refrigerate for about 2 hours to set.
Create the Coverage:
Mix the melted milk chocolate with sour cream until smooth, then cover the entire pavé.
Decorate with melted white chocolate in a beautiful pattern and refrigerate again for 2 hours before serving.
