Prepare the custard: beat the eggs with the sugar until the sugar is completely dissolved. The mixture should become completely homogeneous. Next, add flour and 3-4 tbsp. l. cold milk - mix.
Bring the remaining milk to a boil and pour, whisking constantly, into the egg mixture. Put the mixture on the fire and, stirring constantly, bring to a boil until the mixture thickens. Then add butter and cool.
Dip vanilla crackers (do not soak) in milk, transfer to a blender and grind until crumbs.
Add cocoa, boiled condensed milk to the ground crackers and mix. You should get a viscous mass.
Take a small amount of the resulting mass, put a little cream and cashews on the center. Roll into a ball and roll in coconut flakes. Put the finished balls in the refrigerator to cool for 30 minutes.
