Spray a 9x13-inch pan with cooking spray, line with parchment (with an overhang for removal). Melt butter in microwave and set aside to cool to room temp.

Fold in chocolate chips plus M&Ms. If needed, switch to electric hand mixers, but don't over mix. Press dough evenly into pan. If desired, press a few more chocolate chips & M&Ms into tops of bars.BAKE: 23-28 minutes until top isn't glossy, edges are lightly golden. Be careful to not over-bake for soft & chewy bars. Optional: top with sea salt right out of the oven. Fully cool in pan, lift out, cut, and serve. Best within 1-2 days. Recipe NotesNote 1: You can discard egg white or save and add it to breakfast the next morning (we love this Egg Skillet) or use it in our favorite Egg Wrap. Note 2: Maple syrup is the "secret ingredient" in these bars. In a pinch, you can leave it out, but the bars do lack a bit of tenderness and a certain level of sweetness. I use pure maple syrup, not to be confused with pancake syrup.
