Preheat over to 350 degrees F.
Mix together the brown sugar, sugar, & vanilla
Add flour, egg, pinch of salt, mix well
Add half a cup of M&M’S
It’ll be sticky and thick! Get a 9x13 baking pan, line with foil, spray with nonstick cooking spray
Put dough in pan and spread it evenly
Cook 20-25 minutes. You want it to be doughy still, almost like a cake pop!
You can cut into squares or even cut out with cookie cutters like I did!
Optional- add melted butter on top (tiniest bit) and add sprinkles!
