Confetti Bars

These bars are a staple at any Manitoba holiday spread... quick to come together, and even quicker to disappear!

  • 1 Package Butterscotch Chips
  • 1 Cup Smooth Peanut Butter
  • ½ Cup Butter
  • 1 Small Bag Rainbow Mini Marshmallows


  • In a glass bowl, heat butterscotch chips, peanut butter, and butter. I like to microwave it for a minute or so, until the chips are about half melted. Stir until everything is melted, combined, and smooth.
  • Add in mini marshmallows, stir until all are evenly coated. Use between ½ and 1 small bag of them, depending on your tastes. I usually use about ⅔ of a bag, but used a whole bag for this batch (as pictured). Sometimes you want more of the “fudge” part, sometimes you want more marshmallows. These bars are NOT a hard science 🙂
  • When marshmallows are coated, spread mixture into a lightly greased pan. (I used 8″ x 8″ for 2″ thick bars, 9″ x 13″ is a popular size to use for thinner bars.) Chill until set.
  • Slice up and serve!
