Preheat the oven to 350°F. Use parchment paper to line a 12-inch pizza pan or lightly grease it.

Mix melted butter with sugar in a big bowl until it looks shiny. Crack in the eggs one by one, mixing each in well. Stir in the vanilla.

In a separate bowl, whisk the flour and salt together. Slowly add this to the wet mixture, stirring until it's just blended. Try not to overdo it.

Use a spatula to fold in the white chocolate chips and M&M's (reserve a little extra for topping later). The mixture will be thick and fun!

Spread the batter evenly into your prepared pan and smooth it out a bit. Bake it for 25-30 minutes, until the edges are golden and a toothpick comes out almost clean with a few crumbs.

Let it completely cool in the pan before you finish it off. Once it's cooled, sprinkle the leftover M&M’s on top, cut it up like pizza slices, and dig in!
