In a large bowl, stir melted butter with granulated sugar until smooth and glossy.

Add eggs one at a time, mixing thoroughly after each addition. Stir in vanilla extract until evenly distributed.

Whisk together flour and salt in a separate bowl. Gradually fold into the wet mixture just until combined to avoid overmixing.

Allow to cool completely in the pan. Sprinkle remaining M&Ms on top before slicing into wedges for serving.
