Instructions

To begin, line the base and sides of an 18 x 28cm slice tray with baking paper - making sure you leave the paper hanging over the edges.
In a large bowl, add the rice bubbles and set aside until needed.
Place the butter and marshmallows in a small saucepan and cook over a medium heat stirring occasionally until they have both melted and combined.
Pour the melted mixture quickly into the bowl with the rice bubbles, and mix until combined.
Pour the combined mixture into a slice tin and use a metal spoon to spread across the tin and push down.
Sprinkle 100s and 1000s over the top (optional) and place in the fridge for two hours or until set.
Once set, remove the slice from the fridge and cut into small squares.

Notes

This slice is best stored in the fridge and enjoyed within 5 days of making.

If you can't find Rice Bubbles, you can use alternatives such as Rice Krispies.

You can also use both pink and white marshmallows for this recipe, if using pink, the slice will have a slight colour to it.

When pushing the slice down into the tray, I find using a metal spoon or spatula to be the most effective method.

You can sprinkle 100s and 100s over the top of the slice before placing into the fridge if you wish.

To make Rice Bubble Bars, simple cut the slice in half lengthways and then into bars.

I used an 28 x 18cm slice tin to make the recipe pictured, you can use different sized baking dishes however the depth of the slice will vary.
