Melt in your mouth, buttery shortbread base, with soft, thick, fluffy marshmallow!!!! homemade marshmallow slice – YUMMY!!!
marshmallow slice can be a bit time-consuming, as it has two elements to make. The shortbread base which is really quick and easy to make, but then you have to cook it and wait for it to be totally cool before even attempting to pour the marshmallow on top.
While the shortbread is cooling, make the marshmallow. You really need to beat the gelatine and dextrose mixture for around 10 minutes to make sure your marshmallow is beautifully light and fluffy.
I would not recommend making the marshmallow until your shortbread is cold, otherwise you will end up with a bowl full of set marshmallow and it WILL NOT spread on top of your shortbread base.
I normally leave my marshmallow white, but you can add food colouring at the same time you add the vanilla extract. I’m not too keen on food colouring, but there are loads of good natural options if you want to change things up a bit.
Having said that it is time-consuming it is also super easy, but looks fabulous and is great for kids parties or a lovely afternoon tea with friends or family.
Prior to being sugar free, if we ever went to a bakery my kids would most certainly choose the huge sugar laden, teeth rotting, marshmallow slice.
It’s nice to know now that I have control over exactly what ingredient are in the treats that the kids are eating and I can at least appease myself somewhat to know that my marshmallow slice is a lot better for us, although still a treat,
For an extra special treat you can spread raspberry chia seed jam over the base before putting the marshmallow on.
