Avalanche Cookies and Bars: A New Year’s Eve Delight

When my wife and I stumbled upon a recipe for “avalanche cookies” shared by another member, we were intrigued. We decided to try making them with our own twist. These treats are perfect for New Year’s Eve, combining the rich flavors of white chocolate and peanut butter with the crunch of Rice Krispie cereal and the fun of M&M’s and marshmallows. Here’s how we made them, along with some tips, reasons to love them, and storage suggestions.


  • 1 bag of white chocolate chips
  • 2 cups of Rice Krispie cereal
  • 1 cup of melted peanut butter
  • 1 cup of M&M’s
  • 1 cup of marshmallows


  1. Melt the Chocolate and Peanut Butter: Begin by melting the white chocolate chips in a saucepan over low heat. Stir continuously to prevent burning. Once the chocolate chips are completely melted, pour in the melted peanut butter. Stir until the peanut butter is fully incorporated and you have a smooth mixture.
  2. Mix with Cereal: Remove the saucepan from the heat. Pour the Rice Krispie cereal into the mixture and stir until the cereal is evenly coated with the chocolate and peanut butter mixture.
  3. Add Marshmallows and M&M’s: Gently fold in the marshmallows and M&M’s. Make sure they are evenly distributed throughout the mixture.
  4. Form Cookies and Bars: Using a cookie scoop, form the mixture into cookies. Place them on a baking sheet lined with parchment paper. For the remaining mixture, use a springform pan to shape it into bars.
  5. Refrigerate: Place the cookies and bars in the refrigerator until they are cold and firm. This usually takes about 30 minutes to an hour.
  6. Enjoy: Once chilled, your avalanche cookies and bars are ready to enjoy!
