Margarine tubes with boiled condensed milk

It's no secret that patients often thank the medical staff more than they can. I have a friend who works as a nurse. A lonely granny with a fracture got to them in the hospital. Tanyushka took care of her, treated her grandmother like a human being. When the old lady checked out, she disappeared for a while, and a week later a large basket was brought to Tanya's post, in which there were waffle tubes with condensed milk like flowers. Grandma baked a treat for the whole shift. This delicious meal was enough for everyone, even the patients. Do you want to cook such tubes at home? Please, here's a recipe for you.
Melt margarine, mix it with eggs, add salt. Sift the flour through a fine sieve and add it to the mixture. We add milk in such an amount that the dough turns out to be viscous and viscous.
For baking tubes, there should be a waffle iron in your arsenal of kitchen utensils. The resulting dough is poured into a waffle iron and baked. You can shape the tubes if the dough is hot. We put a little condensed milk on the waffle and roll it up. We wait until the product cools down so that the boiled condensed milk does not leak out.
