This cake dough is made on a steam bath. Preheat water, using a bowl, on top of the boiling water; make sure the bowl does not melt. Place butter, honey and sugar; let it stand there, until it is all melted.
In a separate bowl, beat eggs with baking soda until they have one consistency. Slowly, add egg mixture to the batter, continue mixing the whole time while adding.
Cook for about 30-40 minutes, until the color changes. Take it off the steam bath, add vanilla extract and let it sit for 10 minutes. Add flour to the dough; it may still be sticky after adding flour. Preheat the oven to 350F and line baking sheet with parchment paper.
Here is the trick to rolling it out - easy. Flour surface generously. Because the dough is sticky, this will help you work easier with the dough. Also you can weigh each dough piece; this way they all will turn out the same size. Make sure it measures to be large enough for the shape you will cut out later.
To move it to the baking sheet, roll it on top of roller, and unroll it onto the baking sheet.
Bake for 5-7 minutes, until golden brown. During the process of baking, roll out another layer to speed up the process. When it's done, remove it from the oven and cut out each circle by placing a plate over the top. This is the key trick to making all of the sides perfect - is to cut the cake after baking. You'll need the cut off pieces for later decoration.
Do not immediately stack the layers on top of each other, as they will lose its even shape. Rather, make sure they first cool off on a flat surface.
Repeat until you are done.
