Preheat oven to 400º. Combine cherries, lemon juice, sugar, and corn starch into a skillet and cook over low to medium heat, stirring occasionally until everything is mixed.
Roll out pie crust dough and cut in half. Line inside of one jar with one half of rolled out dough. Repeat with remaining jars and pie crust dough.
Scoop out the cherry filling into the dough-lined Mason jar. Slice strips of dough from the other half of the pie crust for the lattice. Interweave the strips of dough on top of the Mason jar to form the lattice. Trim as needed. Brush melted butter over the top of the lattice and sprinkle on sanding sugar.
Bake at 400º for 20-25 minutes or until golden brown. Top with whipped cream.
