Notes
RECIPE NOTES & TIPS
Marshmallow size - use regular-sized marshmallows (like Pascall's brand) as they melt easily than jumbo or mini marshmallows.
Marshmallow colour - I like to use white marshmallows, however, you can use a combination of pink and white if you prefer. Note: if you use pink and white marshmallows, the slice will have a slight pink colour to it.
Use a new box of Rice Bubbles - it's important to use a brand new (unopened) box of rice bubbles. Using rice bubbles that have been sitting opened in the pantry may not be as crispy and fresh and lead to a stale tasting rice bubble and marshmallow slice.
Brand of puffed rice - while you can use any brand (or home brand) puffed rice that you like, I find that the Kellogg's brand of rice bubbles gives the crunchiest and best tasting result.
Press the mixture firmly into the tin - use the back of a spoon to press the mixture very firmly into the baking tin. This will ensure the slice stays together when cutting.
Storing - store the rice bubbles slice in an airtight container for up to one week. Storing the marshmallow rice krispies in the fridge keeps them deliciously crunchy.
Freeze - freeze in an airtight container for up to 3 months. Allow to defrost in the fridge before consuming.
