Butterfinger Rice Krispie Treats

Rice Krispie Treats are a hit in my household always; kids love recipe like this no matter what! This version of the yummy treat takes it to the next level. They have butterfinger chunks in every bite! If you like butterfingers – this is a must try recipe for you!

This recipe not only tastes good, but it is super simple to make and it has simple ingredients too. Cereal bars are the best dessert for when you’re on a time crunch! Plus – the butterfingers add a great texture.

Ingredients Needed

  • Butterfingers: Get full size candy bars or mini candy bars to chop, or use butterfinger pieces, which I love for making Butterfinger Pie.
  • Marshmallows: I used one bag mini marshmallows but you can also use large ones. Mini marshmallows just melt easier.
  • Rice Krispie Treats: Any size box is up to you, but buy the regular flavor.
  • Butter: I always use and prefer unsalted butter.

How to make Butterfinger Krispie Treats

  • Place butter and marshmallows in a large microwave safe bowl. Heat, stirring often, until butter melts into the marshmallows. You can also do this in a large pot over medium low heat.
  • Stir cereal into marshmallow mixture, then stir in butterfinger chunks.
  • Press into a 9×13-inch pan and allow to cool.

Expert Tips

  • Have all your ingredients measured and ready to go before you start. It’s a fast process and can get quite hectic.
  • I recommend using a really large bowl because if not, the cereal might end up on the floor.
  • You could add 1/4 cup of peanut butter to the marshmallow mixture while you’re heating it if you want these extra peanut buttery. Or add 1 cup of peanut butter chips!
  • Spray your clean hands with non-stick cooking spray before pressing them down in the pan. This will save you even more time and less mess!


  • Store them in a covered container at room temperature for up to 3 days.
  • Freeze these in an airtight container in the freezer for up to 3 months. Place pieces of wax paper or parchment between the bars so they don’t stick together.

  1. I think it’s cute that you put that they could be stored for up to 3 days.  Umm, these may not last 3 hours!

  2. Yay for a brand new kitchen.  Not so much yay for cleaning out garages that want to swallow you whole!  I cannot wait to see all the fun kitchen prep!  It will be awesome when it is all done!  And until then, munch on RKT…I love all the Butterfinger goodness going on in these!!!

  3. Oh these are soooo fun!! I just made my first krispie treats the other day, how embarrassing?!?! Do not worry about everyone having perfect houses, we have 4 rooms + 2 bathrooms that are clear enough for visitors… the rest of the house is chaos!!! Obviously I need a hundred bags of sugar and chocolate chips in the house…! 🙂
