Beat eggs with salt powder, then add the rest of the ingredients and mix the composition.
We put the composition in a larger cup or bowl, it does not have to be full, because it will grow.
Put in the microwave and bake for 4 minutes at 800 W.
After it is baked, we turn it over on a plate and let it cool, then we cut it into 3.
We syrup the tops with a little water, mixed with sugar and a little rum essence, after which we will fill each top with nutella.
On top we decorate it with blueberry jam, or you can leave it unadorned.
