Frequently Asked Questions

Why are my Rice Krispie treats too hard?

Overcooking the marshmallow and butter mixture can lead to harder treats. It’s best to melt them just until smooth.

Can I use chunky peanut butter?

Yes, chunky peanut butter can be used for a different texture and added crunch.

Why did my treats turn out too sticky?

This could be due to not using enough Rice Krispie cereal or not pressing the mixture firmly into the pan.

What if the mixture is too dry?

A dry mixture might result from too much Rice Krispies or old marshmallows. Ensure your ingredients are fresh and appropriately measured.


  • Butter: You can substitute with refined coconut oil or a plant-based butter substitute for a dairy-free version.
  • Mini marshmallows: Large marshmallows can be used, but they might take longer to melt.
  • Peanut Butter: Almond, cashew, or really any other nut butter can be a delicious alternative.


  • Chocolate Chips: Add in some chocolate chips for a sweet contrast.
  • Caramel Drizzle: A light drizzle of caramel on top can add an extra layer of flavor.
  • Sea Salt or Crushed Peanuts: For those who like a mix of sweet and savory, sprinkle a bit of sea salt or crushed peanuts on top.

Tips From the Chef

  • Use a fresh bag of marshmallows for optimal melting.
  • Stir the mixture constantly to prevent burning.
