Instructions

Preheat the oven to 350°F. Grease a 9x13-inch pan with cooking spray and line with parchment paper (I don’t recommend lining with foil). These bars are sticky, so you do want the parchment paper.
In a large bowl, combine the room-temperature butter with the granulated sugar and light brown sugar in a medium bowl. Beat with hand mixer (or in a stand mixer) until light and creamy. Add in the egg, egg yolk, and vanilla. Mix until combined.
In a separate large bowl, combine the flour, baking soda, and salt. Stir. Add wet ingredients to dry ingredients and stir until just combined. With a wooden spoon, stir in 1 cup of white chocolate chips and stir until combined.
Press the cookie dough into the prepared 9x13-inch pan. Bake the bars for 22–26 minutes or until the top is no longer glossy and edges are ever-so-slightly browned. Remove from the oven and immediately top with the mini marshmallows. Return to the oven for 1 minute and 30 seconds.
Gently press the marshmallows down a little. Sprinkle the remaining 1/4 cup white chocolate chips evenly over the bars. Sprinkle the M&M’s evenly over the bars. Scatter the sprinkles evenly over the bars.
Let cool completely (these bars take 1–3 hours to really set up), then cut with a hot, sharp knife (run the knife under hot water, dry, make a slice, repeat). Confetti Bars are best enjoyed within 1–2 days; after that, the marshmallows become unpleasant.
