Beans boil until tender, as directed on the package.

Hot beans to turn into a puree using a blender. Add butter and grind in a blender into a homogeneous mass.

Then add the yolk and salt, mix well. Then crumble the yeast and mix well.

Small portions to pour the flour, knead the dough and shape it into a ball. It is soft and smooth. Wrap in plastic wrap and put into the fridge overnight to "rest".

In the morning, remove dough, roll it into a layer with a thickness of 1,5-2 cm, and make shallow slits with a knife.

Cut a groove with a diameter of 2-4 cm, muffins, lay them on a baking tray lined with baking paper, and give "rest" for 20-30 minutes. Then brush with beaten egg and bake in a preheated 200 deg. the oven for about 12-15 minutes. I divided the dough into 2 parts and one part cut out notch 4 cm (got 16 donuts), and another notch 2cm (got 22 muffins). Liked the little beauties, one bite.

Serve dumplings with sour cream, sauce, jam, or separately. Bon appetit!
