Cheese cake with mice

Cooked this cake for my husband and me on our birthdays.
Beat eggs, sugar and vanilla sugar very well.
Continuing to beat, pour in refined vegetable oil, and immediately milk and cocoa powder.
Mix flour with baking powder and sift into the main mass, beat everything well.
Pour the dough into a form lined with parchment paper and greased with vegetable oil.
Bake in a preheated 180 degree oven for 45 minutes (I baked a little more). Remove the finished cake and let it cool.
Since my family loves meringue, I decided to bake it and insert it into the cake.
For it, we need to VERY carefully separate the whites from the yolks.
Whisk the whites with half the sugar, at the maximum speed of the mixer, gradually adding a tablespoon of the remaining sugar.
Whisk until thick peaks, then add starch, and whisk a little more. Now pour in the peanuts and mix gently with a spoon from the bottom up. We spread the finished dough on a baking sheet covered with parchment, according to the size of our cake, and bake, or rather, dry in the oven at 100 degrees, for two hours. Put the finished cake aside to cool down.
For the cream, we need to take chicken yolks, mix them with sugar and cocoa. Then add the milk, and send it to the fire, where we constantly stir. Cook until thick, then remove and let cool.
After the mass has cooled, beat the butter and gradually add the cocoa mass to the butter. The cream is ready.
Now let's start assembling our cake.
Cut the cakes in half and impregnate with syrup.
Lubricate the bottom cake with cream, put meringue on it, also smear with cream and cover with a second cake. The remains of the meringue are cut off, aligned along the base of our cakes.
The top and sides are coated with cream and sent to the refrigerator.
After our cake has cooled down a little, we start decorating it.
To begin with, we cut out a piece from it and put it off, it's not necessary to do this, but I liked it more))).And so, we take yellow mastic. We roll out and cover our cake with it, align and trim the excess. In the same way, we cover the piece that was cut out, put it on top of the cake.
Now we make depressions, as if holes in cheese (I made them with a rolling pin handle). Well, the cake is ready, it remains only to plant mice. I made mice out of gray mastic, and from the remaining yellow I made pieces of cheese and scattered it all over the cake. That's what happened. Everyone really liked it!!!
P.S. There is a little hack in the design, do not judge strictly))))
