Cookies and nuts are crushed in a shredder or in a package, rolling with a rolling pin.
Melt the chocolate together with the butter in a steam bath.
Pour into the liver with nuts. Stir.
Add condensed milk if desired, adjusting the sweetness. My chocolate is black, not too sweet.
I find it convenient to shape with a sushi Mat. Put the foil with the film on it. Spread the prepared mass in the form of a rectangle ≈ 22 ×17 cm and a height of 1.5-2 cm.
In the middle of the mass, make a small depression in which we spread the peeled and cut in half banana. My daughter asked me to put a kiwi, so I took a small banana.
Lift the edges of the Mat with foil and connect the top, giving the mass the shape of a pyramid (triangle). Put in the refrigerator for 2-3 hours, so that the mass is well frozen.Unfold the foil, carefully transfer to a plate. Melt the white chocolate with milk, decorate the dessert on top and sprinkle with coconut shavings, simulating snow.
It turns out that such a mountain or house.
Cut the dessert into separate cakes-houses. Enjoy)
