You can just use one bag on mini creme eggs for this recipe, however to ensure you have lots of creme eggs in each bite, I like to use 1 ½ packs plus a few bigger creme eggs.
Take care not to overcook these brownies, as you want them to be gooey in the middle and not completely cooked through like a cake.
Store these brownies in an airtight container for 2 - 3 days.
