Writing about these Marshmallow Slice recipe brings a smile to my face. I wish I could time capsule the moment I shared with my son and daughter making them, because these are the types of moments I want to cherish forever: Sharing the joy of baking together on a beautiful, sunny afternoon. Mixing and measuring, sifting and stirring–making a mess!… and then happily enjoying the spoils together.

As my son was licking marshmallow off the beaters he kept saying, “You’re the best, Mum (Mom)! You’re the best cook in the world. If anyone comes this house and doesn’t like your cooking, I’m going to kick them out!” He made me laugh! Nothing like straight sugar to win the heart of your 6 year old.

The fluffy marshmallow topping is a real crowd pleaser

I’d never made marshmallow before this recipe and I loved it! As we beat the mixture it went from a transparent, oily-looking consistency to a foamy, egg white appearance to finally thick, white and glossy clouds. Like magic! My son and daughter enjoyed taking turns with the beaters, watching the mixture change properties.

Our daughter Ruby loved making this Marshmallow Slice

I do need to give you a warning, though: the marshmallow sets really fast! By the time I had spread the jam over the biscuit base the marshmallow was mostly set and I had a lot of trouble spreading it. So ensure you spread the jam before you begin making the marshmallow. That way, as soon as you’ve finished beating the marshmallow you’ll be ready to spread it right away. Have fun!
