I used Patriotic Funfetti Cake Mix, but any Funfetti cake mix variety will work.
Do not overbake. The bars will continue to set as they cool.
Reserve some M&M's for topping after baking for a bakery-style look.
Store leftovers in an airtight container at room temperature for up to 5 days.
Freeze individual bars for up to 3 months.
