Today I am going to share with you a delicious Hungarian Decadent Chocolate Cake recipe. Maybe you have heard of it.  

This is a recipe inspired by the classic Rigó Jancsi cake, named after the legendary Hungarian Gypsy violinist.

If you have never had this cake before, you do not know what you are missing. For chocolate lovers and not only, but this cake is also a must-try.

Once you have had it, this recipe will become one of the family treasures. At least, this is what happened in our house, and I am confident that it will happen in yours as well.

Moist and delicious, with a hint of rum flavor and coffee (flavors that are so traditional in Eastern Europe), the cake has a decadent layer of chocolate ganache and a glaze that makes the cake really handsome and presentable.

This is an elegant dessert that resembles the rich, decadent life of the 19th century in the Austro-Hungarian Empire. 

Before you start making this recipe, please read the instructions carefully. It is not a difficult dessert to make, but it has some things that you need to pay attention to.

For example, the cake batter has a little bit of baking soda in the mixture, but the air incorporated in the egg whites will help the cake rise beautifully, so make sure you beat the eggs really well, stiff but not dry.

You will also need a 9×9″ cake pan

Remember: After you make the chocolate ganache, you will need to set aside 1 cup of it for the final glaze. Don’t forget about it. It happened to me.

Serve the cake by cutting it into small equal pieces. For cutting, use a sharp knife that has been dipped in warm water. Rinse the knife and dip it again in warm water before each cutting.

Now, let’s make the cake and enjoy it!
