Ingredients for Marshmallow Rice Bubble Slice Recipe
To make up this easy Rice Bubble Slice you need:
- Rice Bubbles (or you might call them Rice Krispies)
- Butter
- Marshmallows
- Sprinkles (for decorating – optional, of course).
Here, I've used white marshmallows only. I just like how this slice looks using only white marshmallows.
However you can use the mixed pink and white pack of marshmallows and your slice will just be a pale pink colour.
For ingredient quantities, refer to the recipe card at the bottom of this post.
You'll also need a slice tin of about 28 x 18 cm.
How to make Rice Bubble Slice
Start by greasing the tin and line with baking paper, leaving a little paper overhanging at the sides to assist with removal of the slice from the tin later.
Melt butter and marshmallows together
Next, you melt the butter and marshmallows over LOW heat until the mixture is completely melted and smooth.
IMPORTANT: Remember, keep the heat low and continue to stir so the mixture doesn't burn or stick to the bottom of the saucepan.
Combine melted mixture with rice bubbles
Next, pour the butter and marshmallow mixture over the rice bubbles and stir to combine.
Press into slice tin
Pour the mixture into the slice tin, then use another piece of baking paper on top of the mixture to press it into the tin using the back of a metal spoon.
The mixture will be too sticky at first to smooth it with the spoon directly. You'll need the baking paper between the mixture and the spoon and then, once it's quite level, you can use the back of a spoon directly on the slice to finish smoothing it out and ensuring it's even.
Decorate and allow to set
Decorate with sprinkles and then place the slice in the fridge to set for at least a couple of hours.
Cut into squares
Cut the slice into squares or bars using a sharp knife.
