Gluten-Free Ingredients you’ll need

With only 4 simple ingredients, you will need:

100g unsalted butter (around 7 tablespoons)
250g gluten-free marshmallows (about 9 oz)
1 tsp vanilla essence
6 cups gluten-free rice bubbles, gf rice krispies or gf puffed rice cereal

Note: Be sure that your marshmallows and rice cereal are both certified gluten-free, as many can contain hidden gluten (especially malt extract in rice cereals).

Ingredients For Gluten-Free Rice Krispie Bars

Step by Step Instructions

Step 1: Use a rectangle-sized tray (approx. 9 x 13 inch / 23 x 33 cm) and line it with baking paper, leaving some overhang for easy lifting.

Step 2: Melt butter & marshmallows: In a large pot over low heat, melt the butter. Add the marshmallows and stir continuously until completely melted and smooth. Turn off the heat and stir in vanilla essence.

Step 3: Stir in cereal: Add the gluten-free rice bubbles and stir quickly to combine everything evenly.

Step 4: Press into tray – pour the mixture into the prepared tray. Use a lightly greased spatula or a piece of baking paper to press the mixture firmly and evenly into the tray.

Step 5: Cool & slice – let it cool at room temperature for about 30 minutes (or refrigerate for faster setting), then lift it out and slice into squares or bars.

Storage Instructions

Store in an airtight container at room temperature for up to 4 days.
For longer freshness, keep them in the fridge for up to a week (they’ll be a bit firmer, but not teeth-breaking hard – and still delicious!).
You can also freeze them for up to 2 months – just layer between baking paper in an airtight container.

Fun Variations:

🍫 Chocolate Topped: Melt some gluten-free chocolate and pour over the top before setting.
🌈 Sprinkles: Add gluten-free rainbow sprinkles before pressing into the tray for party vibes.
🥜 Nut Butter Swirl: Stir in a tablespoon or two of peanut butter for a nutty flavour twist.

Make It With the Kids!

This is the perfect recipe to get little hands involved. They’ll love watching the marshmallows melt, stirring the mix, and pressing it into the tray. Bonus: there’s no hot oven to worry about, though the melted marshmallow mixture does get hot and sticky!
