Equipment

  • 13"x9" Baking Pan
  • Mixing Bowls
  • Measuring Cups and Spoons
  • Microwave or Double Boiler
  • Large Saucepan or Saute Pan

Ingredients
 
 

  • 7 Tbsp Salted Butter* divided - 98g
  • 1 Tsp Clear Vanilla Extract 4g
  • 6 Cups Mini Marshmallows (one 10-oz bag) 300g
  • 4 Cups Rice Krispies® Cereal 112g
  • 3 Cups Cap'n Crunch's Birthday Crunch™ or Oops! All Berries® Cereal 120g
  • 2 Cups White Chocolate Chips (one 12-oz bag) 340g
  • Cup + 1 ½ Tbsp Heavy Cream 97g
  • ¼ Cup Rainbow Sprinkles 40g

Instructions
 

For the Bars

  • Use 1 Tbsp of butter to grease a 13"x9" baking pan. Add a strip of parchment paper to help with easy bar removal, and butter that as well. Set aside.
  • Melt the remaining 6 Tbsp of butter in a large saucepan or saute pan over medium heat. Continue to heat the butter, whisking occasionally. As it starts to bubble, whisk constantly until the solids at the bottom of the pan begin to turn brown and you smell a nutty aroma. This process can take up to 10 minutes, and once the butter starts to turn brown--it can burn very quickly.
  • Turn the heat to low, and add the vanilla extract (it'll bubble a second) and all but ½ to 1 cup of marshmallows. Stir continuously to mix with the butter until the marshmallows melt into a smooth mixture, about 1-2 minutes longer. It will brown slightly.
  • Remove the pan from the heat. Stir in both cereals and remaining marshmallows until combined. Pour the mixture into the prepared 13"x9" pan. With buttered fingers or the bottom of a glass cup, press down on the mixture with moderate intensity to spread it evenly in the pan. Do not press too hard that the bars overly compact, which can make them harder to eat (they should be about 1 ¼" - 1 ½" thick when you're done this step). Set aside to cool while you prepare the ganache.

For the Ganache

  • In a large microwave safe bowl, stir together the white chocolate chips and cream. Heat on half power in 30 second increments, stirring between each session until the mixture is smooth and easy to pour.
  • Pour the ganache evenly over the bars, and use an offset or rubber spatula to spread it out if needed. Add sprinkles over the ganache, and place uncovered in the refrigerator to allow the bars to fully set. These bars can stay out at room temperature in an airtight container for up to 2 days.

Notes

Salted Butter: If you only have unsalted butter on hand, don't fret! Stir 3/4 tsp of sea salt or table salt into the melted butter.
