This video provides a detailed explanation of how to make double chocolate cupcakes. First, melt the sweet chocolate and unsalted butter in a double boiler until smooth. Next, whisk the eggs and granulated sugar with a hand mixer, then sift in the cake flour, almond flour, and cocoa powder and mix well. Add the melted chocolate to complete the batter, pour it into muffin tins, and bake in the oven. While the baked cupcakes are cooling, prepare the chocolate cream. Melt the sweet chocolate with the heavy cream in a double boiler, then whisk the other heavy cream and granulated sugar, and mix both together. Put the finished chocolate cream into a piping bag, decorate the cooled cupcakes, and garnish with Meltykiss chocolate and mint leaves to complete your beautiful double chocolate cupcakes.
