Funfetti Rice Krispies

Quick, easy, no baking involved and a one bowl recipe - I absolutely love these family friendly recipes that can bring just as much joy in creating them as there is in sharing and eating them! A bright and beautiful twist on a childhood classic, rice krispie squares with chunks of fluffy marshmallows through and colourful, sweet sprinkles.

Total time to make : 15 mins + chill time (1hr)

Servings : 9 large squares or 12


90g butter

140g rice krispies

300g mini white marshmallows

80g sprinkles - I LOVE these bright ones that don't bleed into the batter

1/2 tsp vanilla extract

Pinch salt


  1. Line an 8 x 8" baking tin with baking paper. Spray the baking paper on top with cooking spray or a very thin smear of butter to grease (so it's not visible) - this will ensure the mixture doesn't stick to the paper once set.

  2. Melt the butter in large saucepan over a medium heat (this will be our mixing bowl too - so it needs to be big enough to hold all of the ingredients in!).

  3. Once the butter is melted, add in 2/3 of the marshmallows and continue on a medium heat, stirring with a spatula until everything is melted down and smooth. Turn off the heat and add the vanilla and salt.

  4. Pour in rice krispies and mix through. Add in 1/3 marshmallows and mix. Finally, add in sprinkles and mix through again.

  5. Tip into the prepared baking tin and very gently spread out until even, I like to wet my hands (so the mixture doesn't stick) and use my fingers to spread it out. Don't pack them down hard - as this creates dense, solid blocks.

  6. Set for ~ 1hr at room temp. or in the fridge for ~ 30 mins before slicing.
