Preheat your oven to 175°C (350°F) and line a 9x9-inch (23x23 cm) baking pan with parchment paper.
In a medium saucepan, melt the butter over low heat, stirring occasionally. Once melted, remove it from the heat and let it cool slightly.
In a large mixing bowl, combine the melted butter, light brown sugar, and granulated sugar. Whisk until smooth and creamy.
Add the egg, egg yolk, and vanilla extract to the sugar mixture. Whisk until fully incorporated and the mixture is slightly glossy.
In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually fold the dry ingredients into the wet mixture using a spatula, being careful not to overmix.
Gently fold in 150 grams of M&M candies and white chocolate chips (if using), reserving some of the M&Ms for topping.
Transfer the batter into the prepared baking pan, spreading it out evenly with a spatula.
Sprinkle the remaining M&M candies over the top of the batter, pressing them slightly into the surface.
Bake in the preheated oven for 25-30 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out with a few moist crumbs (do not overbake for chewy blondies).
Allow the blondies to cool completely in the pan on a wire rack before slicing into 12 squares. Serve and enjoy!
