Cake for first graders on September 1 For the first time in the 1st grade

I made a biscuit for the first time, it turned out delicious, weighing 2800 kg. cake, but this is taking into account the weight of mastic. There are no step-by-step photos, since I found out about this site only today, I didn't plan to exhibit anything anywhere before, but I'll fix it)
This cake is called "Golden key - honey cake", found in the notes in the notebook.
Beat eggs with white sugar, add honey diluted with 3 tablespoons of hot water, soda, beat well.
Sift the flour with cocoa.
Mix.
Pour in the nuts and stir well again.
Divide the dough into 3 parts.The dough turns out to be runny, like sour cream, it needs to be spread with a spoon on a baking sheet covered with parchment. Bake 3 cakes at a temperature of 190 degrees.
Let the dough cool down before impregnation for about 6 hours, you can leave it overnight, you can in the morning. In the meantime, let's do the mastic.

Dissolve marshmallow marshmallow 200gr. with 1 tsp butter and a couple of drops of lemon juice in the microwave, about 1 min. Add powdered sugar, sifted gradually kneading a tight dough. Let rest for about 30 minutes. If you use dry dyes, then it is better to first dissolve them in a drop of water, I do it in lemon juice, if you take helium dyes, then they can be put into ready-made mastic. This cake took me 400 gr. marshmallows. I made jewelry blanks a little earlier, since I was at work during the day), BUT since oil is included in the mastic, it is not recommended to make blanks too early.

When it's time to soak our cake with syrup, collect cakes, smear with cream (beat butter with condensed milk + chopped walnuts. We align, make the shape of the book, necessarily better than I did)), I see my mistakes, but you can not hesitate in the comments. IT is important to maximize the perfect preparation of the cake. We put it in the refrigerator for an hour.

Roll out the mastic, preferably not very thinly, since all the errors will be visible and it may break when smoothing. You have only 1 attempt, so try not to miss the size, remove and lay the second time you are unlikely to succeed, except to make a new portion of mastic. I have an iron, but you can just use your hands or improvised means to smooth out the irregularities when laying mastic on the cake.

So, now the most interesting thing, we decorate our masterpiece with edible, previously prepared rulers with pencils, leaves, well, whatever you like, well, or in my case, what happens)) It is better not to do the inscription right away, since the food marker on fresh mastic spreads a little.
Good luck to you in a difficult but sooooo exciting business !!!
