Pro Tips

Crushing butterfingers:
Place unwrapped candy bars in a zipped bag.
Use a rolling pin or mallet to crush them into pieces.
They don’t need to be totally pulverized; just small enough to incorporate with the other ingredients.

Grease or spray your pan:
Use baking spray or a very light coating of butter to grease your baking pan.
These treats are STICKY (hello, marshmallows) and can be a pain to remove if you forget this step.
You can even add a square of parchment paper to the bottom of your dish for extra stickiness prevention.

Work quickly:
After removing the pan from heat, mix in the rice cereal quickly.
Otherwise, everything begins to harden and the batter is more difficult to work with.

Press treats gently:
When adding the krispie treat batter to the pan, use a greased rubber spatula to spread it evenly.
Use a light touch. Pressing too hard will result in hard, dense treats.
The softer you press, the softer and chewier the finished treats will be.

These treats set up quickly right on the counter at room temperature.
Make sure to let them cool completely before slicing and digging in!

What size Butterfingers do you need for this recipe?

I used 3 full sized Butterfingers.
To use fun sized Butterfingers instead, you will need about 9 bars to equal the same amount.

Can I make Rice Krispie Treats with mini marshmallows?

Yes, you can swap mini marshmallows for the full sized ones in this recipe.
You’ll need a full 10 oz bag (or approximately 5 cups) of mini marshmallows.

What’s the best way to cut rice krispie treats?

Use a sharp clean knife or pizza cutter to make even cuts in your pan of krispies treats.
I cut them right in the pan, but some people swear by turning out the whole tray of treats and slicing them up on a cutting board.

Can you freeze rice krispies bars?

I don’t recommend freezing these treats for best results.
The texture of the cereal changes and they don’t taste super fresh after they’ve been thawed.

Good thing these are so irresistibly delicious, the whole pan will disappear long before you can even think about freezing them!
