For the batter: In a large bowl, whisk together the milk, eggs, 2 tablespoons melted butter and vanilla. In another bowl, whisk together the flour, sugar and salt. Combine the dry ingredients into the wet ingredients, whisking out any lumps. Let the batter rest for a few minutes while you prepare the fillings. (Batter can be covered and refrigerated for up to 24 hours, but it may need to be thinned a bit.)
For the fillings: Mix together 1 cup cherry pie filling and the cream cheese; cover and refrigerate until ready to serve. Put the remaining cherry pie filling into a serving bowl. When ready to serve, slice the bananas and put them into a bowl; put the chocolate spread into another bowl.
For the pancakes: Grease the pan with a bit of the melted butter. Pour a scant 1/4 cup of batter into the pan, swirling the pan to coat it evenly. When the top looks dry and bubbles and the edges are lightly browned, 45 seconds to 1 minute, flip the pancake over and cook for an additional 15 to 20 seconds. (The first pancake may not turn out perfect so don't worry if it does not work, eat it as a snack.) Place the pancake onto a plate and continue cooking the remaining batter in the 1/4 cup increments, brushing the pan with melted butter as needed. Stack the pancakes on top of each other and set aside covered with foil until ready to serve. (Pancakes can be covered and refrigerated for up to 24 hours. Pancakes can be placed between layers of wax paper, wrapped in plastic and frozen for up to a month. Thaw overnight in the refrigerator before using.)
To serve: Put the pancakes out along with the bowls of fillings. Fill a pancake with a dollop of 1 of the fillings fold it in half and roll it up like a cigar. Garnish with a dollop of the remaining cherry pie filling or sprinkle with a bit of the powdered sugar.
