Line a 9" square tin with baking paper. I grease the tin first with a little butter to help the paper stick to it
Weigh the rice cereal out into a large mixing bowl, add the salt and stir it in
Put the butter, white marshmallows and vanilla extract into a pan on a low-medium heat and stir together until the butter and marshmallows are fully melted
Pour the melted marshmallow mixture into the rice cereal and stir until the cereal is fully coated
Add the mini pink and white mini marshmallows and stir them in until evenly distributed
Press the mixture gently into the tin into an even layer, I use a silicone spatula to do this, then leave to set for 1 hour
To serve, remove from the tin and cut into squares, store leftovers in an airtight container in a cool place for up to 1 week
Notes
You can use a baking spread like Stork in rice krispie treats, but I much prefer using real butter as I think it tastes better.
Many marshmallows contain beef or pork gelatine so check the packet if you are serving this recipe to vegetarians. I like to use gelatine free marshmallows, one of my favourite brands is Freedom marshmallows, which are available online and in Sainsburys. There are also other gelatine free marshmallow brands like Dandies and Free From Fellows.
I added extra pink and white marshmallows to this recipe for nuggets of gooeyness, but you can omit this step, or swap them for chocolate chips or dried fruit.
Although I provide cup measurements, I highly recommend weighing your ingredients out using digital kitchen scales*. It is the most accurate way to measure ingredients and will ensure the best results. Digital scales are very low cost and can be purchased for around £12 ($16.50) .
For teaspoon (tsp) and tablespoon (tbsp) measurements, please use measuring spoons* and not the type of spoons you eat with. Again this will ensure accuracy and provide the best results.
