I have long wanted to learn how to make beautiful decorations for cakes (I think, not I one)! But how and what you can do, I will tell you now. The recipe is really simple! Most importantly, do everything carefully and quickly!
Put marshmallows in a bowl, add 1 tbsp butter.
Put in microwave for 20-25 seconds. Our marshmallow will increase in volume.
Add the powdered sugar (I added immediately 100 grams).
And begin to knead the dough. In the process, add the powdered sugar until then, until the dough becomes similar to clay (it took me about powdered sugar 120 g).
Roll out on surface dusted with powdered sugar. Cut glass circles.
Now the most interesting. Start to make a rose. Take one circle and turn it into a tube. The last edge is slightly wetted with water and like glue it to the tube.
Take the next circle, in the hands of the fingers, mash it, make it more soft (the slices dry up and if you don't knead in hand, they will burst and then nothing happens) to the middle of the wetted by water (I did it with a brush).
And wrap around the first tubes of this circle.
Similarly, glue more circles (do not forget to stretch your hands), until we have rose!
