WHAT INGREDIENTS DO YOU NEED TO MAKE FRUITY PEBBLES TREATS?
- Fruity Pebbles cereal - Post Fruity pebbles cereal is naturally gluten-free
- Marshmallows - most marshmallows are gluten and dairy-free but not naturally vegan.
- Butter - unsalted butter is what I prefer
- Vanilla extract
TOOLS NEEDED TO MAKE THE RICE CRISPY TREATS:
- large pot - you need a lot of room to stir the treats.
- silicone spatula - I spray my spatula with nonstick spray to help with easy cleanup.
- measuring cups - Pyrex cups are what I have on hand but other dry measuring cups will work.
- 9 x 13 pan - either glass or metal. Be sure to spray with non-stick spray.
- non-stick pan spray
- Chef knife or pizza wheel - once again, spray with non-stick pan spray.

📝 Frequently asked questions, answers and tips:
Fruity pebbles cereal treats also are gluten-free and dairy-free when a dairy-free butter substitute is used. Post Fruity Pebble cereal is labeled gluten-free.
This is why fruity pebbles cereal treats are the perfect allergy-friendly treat to send to school and bake sales.
There are about 8-½ cups of fruity pebbles in each box. That means one box will make a 9x13 pan of sweet treats or grab 2 boxes to make one pan of extra-thick treats or 2 pans of single layer rice crispy treats.
👩🍳 CHEF TIP FOR MAKING RICE KRISPIE TREATS
- Don't let the marshmallows boil. High heat will crystallize the sugars, making the bars hard instead of chewy. Keep the heat just warm enough to melt the marshmallows.
- When melting the marshmallows, allow the marshmallows to melt about 95%. The little bits of marshmallow will give the rice crispy treats pockets of marshmallow.
- Or add 1 cup of mini marshmallows right at the end before stirring in the fruity pebbles.
- Gently press the warm crispy treats into the pan, do not press hard, or compact them.
- Don't let the marshmallows over heat and take on color.
🔪 Tips for slicing:
- Generously spray the pan with nonstick spray before pressing the rice krispie treats into the pan.
- Use a large chef knife that has been dipped in hot water and dried before each cut.
- Or spray a chef knife or pizza wheel with non-stick spray before slicing.
