Notes
RECIPE NOTES & TIPS
Always use a new, unopened box of Rice Bubbles for maximum crunch.
Work quickly when mixing the marshmallow mixture through the cereal — it sets fast.
To stop sticking, grease your spatula or hands lightly with butter before pressing into the tin.
Use a piece of baking paper to press the mixture down firmly and evenly into the tin — it stops the mixture sticking to your spoon or hands and helps the slice hold together when cut.
Slice the bars while still slightly soft (after chilling for 1–2 hours), for neat, clean edges.
Store in an airtight container in the fridge for up to 1 week.
Freeze in individual portions in ziplock bags for up to 3 months. Defrost in the fridge overnight or pop straight into lunchboxes to thaw by recess.
For parties, cut into mini squares so you get more servings out of one batch
