Instructions
  1. In a medium-size light-colored saucepan over medium heat, melt the butter and cook until it’s deep golden and fragrant. When brown specks start to appear, remove it from the heat and immediately transfer the butter with the brown specks to a large bowl. Set aside to cool to room temperature.
  2. Preheat the oven to 350ºF (180ºC). Line an 8-inch square baking pan*** with parchment paper, leaving a couple of inches of overhang.
  3. Whisk together the flour, baking powder and salt in a medium-size bowl until well combined. Set aside.
  4. Add the brown sugar, granulated sugar and vanilla extract to the cooled brown butter and stir until combined. Add the egg and egg yolk and stir vigorously for 1-2 minutes, until smooth and well combined. Stir in the flour mixture just until combined. Set aside a few of the larger chocolate pieces for the top. Gently fold the remaining chocolate pieces and the M & M’s into the dough.
  5. Transfer the dough to the baking pan and smooth the top with a spatula. Arrange the reserved chocolate pieces on the top. Bake until the top is set and light golden brown and a toothpick inserted into the center of the bars comes out with a few moist crumbs on it, about 20-25 minutes. Add the candy eyes and sprinkles while the bars are still warm. Let the bars cool in the pan.
