Mirror Glaze Chocolate Zucchini Cake

Have you ever made a mirror glaze chocolate cake? It is really not as difficult as you might think!

And a nice zucchini cake is a “must” for me every summer, so why not combine the two: zucchini chocolate cake with mirror glaze on top.

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.

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.

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.

It looks amazing!! I never had zucchini cake before, because my husband is not a fan of the idea.
