Ingredient notes:

The ingredients to make white Christmas rice bubble slice on a wooden bench top

Marshmallows: Yes, I separated two bags of pink and white marshmallows so that I could use all the white ones! You could use both colour together if you prefer, you'll just end up with more of a 'Pink Christmas' than a 'White Christmas'!
Rice bubbles: This recipe calls for plain rice bubbles. I've also made it with gluten free rice bubbles in the past!
Toppings: Let your imagination run wild with Christmas themed sprinkles, chocolate and candy. Or, leave it plain if you prefer.

Note: Scroll to the recipe card for the ingredients, quantities and the full method.

Step by step instructions:

Line a 17 x 27cm baking tray with baking paper and set aside. Place the butter in a large saucepan over a low heat and melt. Add the marshmallows to the melted butter. Mix until completely melted and combined.

Recipe FAQs:

Why do you only use white marshmallows?

This helps to keep the rice bubble slice white in colour! I have another recipe for Marshmallow Rice Bubble Slice that uses pink and white marshmallows together and it is very pink! But as always, feel free to use both colours if you prefer.

What other toppings could I use on this slice?

You could also decorate your slice with chocolate drops, crushed candy canes or other Christmas candy.

Storage:

Store your White Christmas Marshmallow Rice Bubble Slice in an airtight container either in the pantry, or the fridge depending on how warm the weather is!

This delicious slice can also be frozen. Once set, cut into pieces then place in airtight bags or containers in the freezer for up to three months.

Top tips:

Other toppings to use could include chocolate chips or mini M&Ms.
You could leave the topping plain if you prefer.
