Ingredients & Substitutions

You only need a few staples. Below are the primary ingredients and easy swaps to make the recipe gluten-free, dairy-free, or vegan.

  • Butter – Use regular butter or a plant-based butter to make these dairy-free/vegan.
  • Mini marshmallows – Choose gluten-free marshmallows; vegan marshmallows are available if you need a plant-based option. Use 8 cups melted and reserve 2 cups to fold in for extra gooey bits.
  • Gluten-free crispy rice cereal – Verify the packaging is certified gluten-free. Many conventional rice cereals include barley malt and are not safe for celiac diets.
  • Coarse sea salt – A pinch heightens flavor and balances the sweetness.
  • Sprinkles (optional) – If adding sprinkles, confirm they’re labeled gluten-free.

How to Make Gluten-Free Rice Krispie Treats

This recipe comes together quickly with a microwave and a little stirring. No stove or oven required.

  1. Prep the pan – Line a 9×13-inch baking dish with parchment and lightly coat with non-stick spray.
  2. Melt butter and marshmallows – In a large microwave-safe bowl, microwave 1/2 cup butter and 8 cups mini marshmallows on high for 1 minute, stir, then heat another minute until smooth and fully melted.
  3. Stir in cereal and salt – Add 6 cups gluten-free rice cereal and 1 teaspoon coarse sea salt. Stir until evenly coated, then let cool 1 minute.
  4. Fold in extra marshmallows – Gently fold in the reserved 2 cups mini marshmallows for extra gooey pockets; stir in sprinkles now if using.
  5. Press and set – Transfer the mixture to the prepared pan and press down gently—avoid over-packing or the bars will be dense. Let cool completely before slicing.

Tips & Tricks for Perfect Rice Krispie Treats

A few small techniques make a big difference in texture and appearance.

  • Use fresh marshmallows – They melt smoothly; stale marshmallows can make the mix stiff.
  • Don’t over-press – Gently pat the mixture into the pan; too much pressure yields tough bars.
  • Grease hands or spatula – A light coating of oil or non-stick spray prevents sticking when shaping.
  • Cut with a hot knife – Run a knife under hot water and dry it before slicing for clean edges.
  • Timing for mix-ins – Stir in chocolate chips or delicate add-ins after the mixture cools a minute to avoid melting them.
  • Room-temperature storage – Keep at room temperature; refrigeration will make them hard.

Fun Flavor Twists

Customize these squares with simple add-ins to make them uniquely yours.

  • Choco-mallow – Fold in 1/2 cup mini chocolate chips with the last marshmallows for melty chocolate pockets.
  • Peanut butter swirl – Stir 1/2 cup natural peanut butter into the melted butter and marshmallow mixture before adding cereal.
  • Salted caramel drizzle – Once cooled, drizzle caramel sauce over the top and finish with flaky sea salt.

How to Store Gluten-Free Rice Krispie Treats

Store bars in an airtight container at room temperature for up to 7 days. For longer storage, wrap individually or separate layers with parchment and freeze in a sealed container for up to 6 months. Thaw or bring to room temperature before serving for the best texture.

Gluten-Free Rice Krispie Treat Recipe FAQs

Are Rice Krispies treats gluten-free?

Not always. Many common rice cereals include malt flavoring from barley, which contains gluten. Always choose a certified gluten-free rice cereal suitable for celiac diets.

Can I make them vegan?

Yes—use plant-based butter and vegan marshmallows to create fully vegan Rice Krispie treats that keep the same texture and flavor.
