Collect our cake in a split form. The cake is high, so I doraschivat form foil. First put a layer of sponge cake. Pour 1/3 of the marshmallow mass, cover with a second biscuit and now half of the marshmallow mass. The last biscuit is covered and pour the remaining mass. We send the cake to the refrigerator to solidify for a few hours (I sent at night).
When the cake froze-spread on top of strawberries.
