Combine flour, corn starch, baking powder, salt and baking soda in a bowl

Using a funnel, pour mixture into bottom of a 1 quart sized mason jar

Slowly pour chocolate candies on top of flour mixture, making sure they don't press too far down into flour

Add brown sugar on top of candies and pack well around the edges (so white sugar doesn't mix into it)

Add layer of white granulated sugar on top

(Note: This mixture won't quite fill all the way up to the top)
