What You Need
- rice bubbles – also called rice krispies or puffed rice. I use Kellogg's brand, but you can use any brand you like.
- honey – for a vegan slice, you can substitute with bee-free honey, agave nectar, or sorghum syrup.
- coconut oil - this helps to give the slice it's delicious crunch. Use liquid coconut oil for this recipe. If you live in a warm climate, your coconut oil will already be liquid. If you live in a cool climate and your coconut oil has solidified, simply warm it into the microwave to melt before using.
- sprinkles – like 100s & 1000s. You can also make your own sprinkles from desiccated coconut.

Recipe Tips & FAQ
Can you freeze rice bubble slice?
Yes absolutely! And you can serve it directly from the freezer as a chilled, crunchy summer treat!
How long does this no-bake rice bubble slice keep?
It will keep in the fridge up to 7 days or frozen for up to 1 month.
How do you press the mixture extra firmly into the tin to stop it from crumbling?
Use a cake tin of the same size to help press the mixture down firmly. Place the empty tin (of the same size) over the top of the tin holding the mixture and press down as hard as you can. It's important that the mixture is pressed down very firmly so that it doesn't crumble when sliced.
Is this slice good for packing in lunchboxes?
This slice is best when eaten while still chilled! Once it sits out, the coconut oil and honey will melt, causing the slice to crumble. They're perfect for after school snacks, though!
How do I cut this slice?
Cut the bars with a very sharp knife while the slice is still in the tin and has been chilled for 3 hours minimum (best overnight). Place the slice pieces back into the fridge as soon as you've cut them.
Can I make this slice in my Thermomix?
Absolutely! I've updated the recipe card below to include both Thermomix and conventional (bowl and spoon) methods.

I always have an ice brick in my son's lunch box for his yoghurt so these might actually stay chilled enough to stay set

That's a great idea!!

If I replace the coconut oil with Copha, do I need to increase the quantity? and will this make a firmer slice? thank you 🙂
Lucy Mathieson
Hi there, I haven't made them with copha so you might need to experiment a little - as long as the rice bubbles are nicely coated it should be fine. xx
di
Hello
How long will these last?
Lucy
Hi Di, these will last a week in the fridge 🙂
Elise
What could the honey be substituted for to make them suitable for under 1s? I’m thinking rice malt syrup or maple syrup, but don’t want them too sugary. And would it be 1:1 swap?
Lucy Mathieson
Hi Elise, you could use rice malt syrup for sure - the only thing is that they wont hold together as well as when you use honey. xx
