Confetti Slice



In my travels to find a rainbow dot blouse I kind of stumbled across this recipe for cake batter rice crispy treats (you know what Google’s like), and they looked so pretty I thought I’d give them a try.

The recipe’s really quick and easy, and would make a great little treat at a special event.


2tbs butter

120g marshmallows

1/4 cup dry packet cake mix (vanilla or butter flavour)

2 1/2 cups of rice bubbles

25g 100s and 1000s


Step 1. Melt the butter in a large saucepan


Step 2. Add the marshmallows to the saucepan & turn the heat down low


Step 3. Stir until the marshmallows have melted, then remove from the heat

Step 5. Add the rice-bubbles and stir in


Step 6. Add the hundreds and thousands, and – working quickly! – gently mix through. Don’t be too vigorous with this step or the colouring will run!


Step 7. Pour the mix into a deep dish that’s been lined with baking paper


Step 8. Using another piece of baking paper you can smoosh the slice flat


Step 9. Let it set for about half an hour – it doesn’t have to go in the fridge, it should set at room temperature.


Step 10. Once it’s set you should be able to cut it into squares with a shape knife

  1. I made avalanche bars- similar but no cake mix- rice bubbles, marshmallows, choc chips and I think leant butter and pretzel sticks- was yummo and my niece and nephews loved it!

  2. Love this! I’m thinking for my 35th this year I might have a rainbow themed party and these squares will be perfect.

    Also ‘rice bubbles’ are called ‘rice crispies’ in the UK. Im always interested in that kind of thing.

  3. ooh, I made a Nutella version of these last night! 4 tbsp butter, package of marshmallows (40) and half cup or so of Nutella then stir in 8 cups of the rice cereal (I’m in the US and used the store branded “Rice Crisps”). Yours are prettier but I think I’d still choose the Nutella =)
