Epiclouds Glacier Banana alternative or recipe?

[matholland618]

I looooooove Glacier Banana by Epiclouds. Problem is, they only sell 30ml bottles...Price isn't too bad $15 a pop. Anyone have a recipe or an alternative that tastes close that is cheaper and can buy bigger bottles?

maybe 5% Banana 3% Cream and 2% Menthol, only guessing from the flavor profile, but it´s always a start
