Sift the powdered ingredients and set aside. Add the milk to a pan and heat on low. Add the minced chocolate and melt while mixing. Once melted stop the heat. Use the remaining heat to melt the butter. Finely chop up the nuts.
Add the egg yolk and 40 g of sugar to a bowl and beat until it becomes white and fluffy. Add to the pot from Step 1 and mix until smooth. Add the cocoa and flour and mix well. Add 50 g of sugar to the egg whites in 3 parts and make a firm meringue.
Divide the meringue into 3 parts and add bit by bit to the pot from Step 2. Mix with a spoon. For the first part mix well, but for the second and third parts mix lightly.
Once everything has been mixed together it'll look like this. Now pour into a pan lined with baking paper, top with the chopped nuts, and cook in your preheated oven at 180°C for 10 minutes, then at 170°C for 15 minutes.
Top with the powdered sugar and it's complete.
Story Behind this Recipe
I wanted to make healthy sweets for my mother who loves chocolate. The taste comes from a friend who made a chocolate cake with nuts for me a long time ago. I was going to eat it a little at a time, but it was so delicious I ended up polishing it off all at once, haha. This really is a recipe I don't want to tell anyone else. This is a healthy snack with a modest sweetness without heavy cream.
Don't boil the milk. I also recommend not using low-fat milk for the best rich taste. For the meringue add some sugar, whip into a fine foam, and then add sugar again…repeat this process. Once it forms peaks and it's firm enough not to fall out of the bowl if turned upside-down it's just right. If you mix in a scooping motion from the bottom of the bowl upwards this keeps the meringue intact. I recommend non-sweet, bitter cocoa.
