Halloween Rice Bubble Slice (Rice Krispies Treats)
This no bake marshmallow rice bubble slice recipe (aka Rice Krispies treats recipe) topped with melted chocolate, candy eyes and marshmallow cobwebs is such a fun halloween recipe that kids love to make (and eat!).
Equipment
- 20cm x 20 cm / 8" x 8" square baking tin
Ingredients
- 3 tablespoons butter ($0.46 / £0.25p)
- 280g (9 ¾ oz) marshmallows ($4.12 / £1.18)
- 170g (4c) Rice Bubbles / Rice Krispies ($0.93 / £0.46p)
- 2-3 tablespoons raspberry jam ($0.13 / £0.07p)
- 200g (7oz) chocolate, milk and dark, roughly chopped ($5.00 / £1.00)
- 1 tablespoon butter ($0.16 / £0.09)
- 2-4 white marshmallows ($0.29 / £0.08)
- edible eyes ($0.60 / £0.30p)
Instructions
- Line a 20cm x 20 cm / 8″ x 8″ square baking tin with greaseproof paper.
- Melt the butter in a medium saucepan then add the marshmallows and gently melt over a low to medium heat, stirring occasionally to make sure they aren’t sticking to the bottom of the pan.
- Add the Rice Bubbles / Rice Krispies and quickly stir to combine.
- Add raspberry jam and stir lightly.
- Tip the mixture in to the lined baking tin and press down with the back of a spoon, using clean fingers greased with butter to press down the top to smooth.
- Melt the milk chocolate and dark chocolate in microwave or bain marie (a heatproof bowl set over a pan of barely simmering water, the bowl shouldn't touch the water), then pour over the marshmallow rice bubbles and smooth.
- Leave to set at room temperature.
- When the chocolate has set make the marshmallow cobwebs – melt the white marshmallows in ban marie then take off the heat and leave to cool slightly for a couple of minutes. Using 2 forks, dip them in the marshmallows and then pull apart slowly and gently to create strands of marshmallows. Keeping the forks apart, lay these strands over the set chocolate. Repeat in a haphazard pattern until the whole of the slice is covered. Decorate with edible eyes. Please see * note below for extra tips on how to make the cobwebs.
- Using a sharp knife to cut into 20-25 squares.
- Optional serving idea: pile cut squares on a plate and decorate with more marshmallow cobwebs.
- The slice is best eaten within 2 days. Store in an airtight container at room temperature.

Notes
Estimated costs: Australia $11.69. Per slice = $0.59
UK £3.43. Per slice = £0.18p
America - I am yet to calculate the estimated ingredients costs to make this recipe in the US. If you would find it useful please let me know and I'll get calculating :)
*How to make marshmallow cobwebs – leave the melted marshmallows for 30 seconds to a minute to set slightly to make it easier to pull strings from them. Use two forks and gently pull them apart to create the strands, pressing down on the edge of the baking tin to make them stick. Don’t touch the marshmallow strands you have already laid across the slice as they will stick to your current ones…and it gets a bit messy. Once slightly set you can use your hands to move the strands to where you want them to go.If the melted marshmallows become too hard to work with: gently reheat in a heatproof bowl set over a pan of simmering water to make them soft again.
Kellogg’s Rice Bubbles – Kellogg’s Rice Krispies if you are in the UK or the US, they also go by the name of rice pops, or you can use any supermarket own brand puffed rice cereal in this recipe.
Marshmallows – I like to use pink and white marshmallows for the slice itself and white marshmallows for the cobwebs., and they are generally easier to find, but you can stick to white marshmallows if you prefer. Use regular size rather than mini marshmallows.
Butter – unsalted butter, or Nuttalex or another dairy free spread.
Raspberry jam – or strawberry jam.
Chocolate – I like to use a mixture of dark chocolate and milk chocolate for the top layer, as all milk chocolate tends to be too sweet, yet all dark chocolate is not as popular with kids. I personally prefer to use a chocolate bar and break in to pieces rather than using chocolate chips.
Don’t over stir the marshmallow / puffed rice cereal mixture when you add the jam, as you want clumps in the slice to look spooky.
Have the Rice Bubbles / Rice Krispies weighed out and ready to go and work quickly mixing them in as the marshmallows will soon start to stiffen once they cool and can be tricky to work with.
