Ingredients.

Bananas wash, break into pieces and make a puree by any available way for You. I used blender. Baking tray lay a parchment, put the mass into a rectangle of thickness 0.5 cm.

Bake at t= 160 40 - 60 min. Time not giving accurate, as much depends on Your oven. The layer is ready when it will no longer be sticky when you touch. There is another FEATURE. If You want to get crisp candies, like a marshmallow, then bake as I wrote. But if You prefer a more gentle, similar to a soufflé, then under the pan place a pan with water. After the surface will tell You that it is ready, remove the tray with water and let stand for 3-4 minutes more. Remove, turn over and immediately remove the parchment. He's recovering well. Grease the surface with jam.

Put in some layers. We get a long rectangle. Then lubricating jelly along the entire length and folded in half. Leave it to cool down.

Cut. Decorate according to Your desire. Cut.
