Preheat oven to 350 degrees. Lower a strip a parchment paper to fit the base of a 9×13 pan, but cling above 2 of the edges. Spray pan with non-stick spray and then area parchment in, pressing paper to spray to enable it stick. (Alternately you could line with foil and frivolously spray with cooking spray.) Established aside.
Position oats in your blender and pulse just a pair times to barely split up oats. You don’t want to make oat flour! They should really still search like oats, just damaged up a little into smaller sized items. Set these aside.
Mix flour, baking soda, and salt in a bowl and frivolously whisk to merge. Established aside.
In a mixing bowl or stand mixer, melted butter, brown sugar, and white sugar. Include eggs, one particular at a time, stirring in between every addition, and vanilla. Include flour mixture in a few additions till incorporated.
Stir in oats and chocolate chips until eventually just put together. *I like to just sprinkle my M&M’s on the prime of the dough, but if you have a significant bag, truly feel free of charge to toss a little handful into the dough, or substitute M&M’s for a portion of your chocolate chips.
Push dough into well prepared pan and press flat. Sprinkle a handful of M&M’s on top rated and incorporate sprinkles if you motivation.
Bake for about 25-30 minutes. Get rid of from oven when edges are golden brown and centre appears established, but however gentle. The center should jiggle a bit when you shift the pan. They will be extremely doughy in the middle! Unless you are serving a bit warm above ice product, interesting absolutely to place temperature. Notice: It’s thoroughly usual for the middle to sink down reduced than the edges, as soon as cooled! I imagine these are ideal when they’ve cooled for many several hours and I like to set them in the fridge to chill just before slicing, even. They are excellent to make in advance!
