How to make the cake?

• The cake is made in a small springform of 20 cm/ 8 inches.
• Finely grate the dark chocolate and the zucchini.
• Mix together the flour, cocoa powder, baking powder, and salt and set aside.
• Cream the butter and the sugar for about 5 minutes.
• Add the eggs, one at a time, mixing well in between.
• Add the flour mixture, the milk, and the rum by turns in 2 or 3 batches.
• Fold in the chocolate and zucchini.
• Bake for about 1 hour. Check if the cake is done by inserting a toothpick in the middle.
• Leave the cake to get cold, then chill it; it has to be well chilled before you pour the mirror glaze on top.

Tips

• Use a kitchen scale to measure the ingredients - it is important.
• It is preferable to use a digital thermometer when making the chocolate mirror glaze. It works without it as well, but it works better if you use it.
• The chocolate mixture should first reach a temperature of 60 degrees Celsius/ 140 degrees Fahrenheit. Now is the time to add the gelatine to the mixture.
• Then again, the perfect temperature to pour the glaze is 29 degrees Celsius/ 84 degrees Fahrenheit.
• To pour the glaze, start by placing a small casserole form that is slightly smaller than the cake in a large roasting tin.
• Place the chilled cake on top of the small form and start pouring the glaze over it.
• Remove excess glaze from under the cake with a knife.
• Refrigerate the cake until serving or decorating.

Otherwise, I hope the summer is treating you well; we finally have a really nice summer day today. Take care, and enjoy the rest of your weekend!

Instructions

Cake:

• Preheat the convection oven to 180 degrees Celsius/ 350 degrees Fahrenheit. Butter the bottom of a 20 cm/8-inch springform and line it with baking paper.
• Finely grate the dark chocolate and the zucchini.
• Mix the flour, cocoa powder, baking powder, and salt and set aside.
• Combine: Cream the butter and the muscovado sugar for about 5 minutes. Add the eggs, one at a time, mixing well in between. Add the flour mixture, the milk, and the rum by turns, in 2 or 3 batches. Finally, fold in the chocolate and zucchini.
• Bake: Pour the mixture into the prepared springform and bake for about 1 hour. Check if the cake is done by inserting a toothpick in the middle. Leave the cake to get cold, then chill it. It has to be well chilled before glazing.

Mirror glaze:

• Soak the gelatine leaves in cold water for about 10 minutes or according to the packet's instructions.
• Dissolve gelatine: Pour the water into a small saucepan. Let it come to a boil and add the sugar. Stir well, remove from heat and add the chopped couverture chocolate. Mix with a hand whisk, add the sifted cocoa powder, mix well and add the heavy cream. Mix again, and when the temperature reaches 60 degrees Celsius/ 140 degrees Fahrenheit, stir in the squeezed gelatin leaves and mix until dissolved.
• Sieve this mixture into a jug and blend with a hand blender. Sieve again into another jug and let cool until the mixture reaches 29 degrees Celsius/ 84 degrees Fahrenheit.
• Glaze: Place a small casserole form that is slightly smaller than the cake in a large roasting tin. Place the chilled cake on top of the small form and start pouring the glaze over it. Remove excess glaze from under the cake with a knife. Refrigerate the cake until serving or decorating.
