FAQs
Can I use regular food coloring instead of gel?
Yes, but regular liquid food coloring may make the marshmallow mixture slightly thinner, which can affect the texture. Gel food coloring is preferred for bright colors without altering consistency.
Can I make these treats gluten-free?
Yes, as long as you use a gluten-free cereal similar to Rice Krispies. Check that all your ingredients, including marshmallows and sprinkles, are gluten-free to ensure the treats are safe for those with gluten sensitivities.
