Key ingredient notes and substitutions
**Please see the recipe card at the bottom of this post for the full list of ingredients.
Ginger nut biscuits
Also known as gingers snaps. These biscuits are readily available in most supermarkets and will form part of the biscuit base.
Alternatively, you can use any other plain biscuits, like digestives biscuits, Graham crackers, Rich tea, Tennis biscuits, Marie biscuits (South Africa), to name but a few.
Butter
We'll mix the melted butter with the ginger crumbs to make the tart base.
Sweetened condensed milk
Depending on where you are in the world, cans of condensed milk may vary slightly in weight.
The difference is usually just a few grams (we use a 397g can). As long as the weight is close enough to this range, it won't impact the quality of the tart.
Lemon juice
Be sure to use freshly squeezed lemon juice for the recipe. Avoid using bottled lemon juice concentrate as it may affect the taste.
Double Cream
Also known as heavy cream. For a lighter tart, you can use single or whipping cream.
Mini marshmallows
You can usually find mini marshmallows in the baking aisles. Look for packs that have a variety of different colours, including the sought-after baby blue marshmallows.
These packs with blue marshmallows are like gold-dust, but if you're in the UK, you might find them at Home Bargains.
You can also use large marshmallows and cut them into smaller pieces with a pair of kitchen scissors.
Glaze cherries
Let's be honest, even the snobbiest of folks can't resist the charm of a glaze cherry, it's true!
How to make a marshmallow tart
The crust:
- Use a food processor to blitz the ginger nut biscuits into a fine crumb.
No food processor? No problem! Just put the ginger nut biscuits in a sturdy plastic bag and crush them with a rolling pin.
- Melt the butter either in the microwave or on the stove top and then combine it with the biscuit crumb.
- Press the crumb mixture firmly into the base of a baking dish, tart pan or an 8-inch springform cake tin.
You can use the back of a spoon or the bottom of a glass to smooth out and press the crumb mixture evenly into the base.
- Place the crust in the fridge to firm up whilst you get on with the filling.
The filling:
- In a large bowl, combine the condensed milk with the freshly squeezed lemon juice.
- Using a hand mixer, whisk or even a fork, whisk the mixture until it begins to thicken slightly. The lemon juice helps the condensed milk thicken.
- In another mixing bowl, whisk the cream until it forms stiff peaks.
- Gently combine the whipped cream with the condensed milk mixture by folding them together until well combined, being careful not to overmix.
- Fold in the mini marshmallows and glaze cherries.
- Spoon the marshmallow mixture onto the biscuit base, then use a spoon to smooth the top. Feel free to decorate it however you like!
- To allow the tart to firm up, place it in the fridge for a minimum of 6 hours. For the best results, it's recommended to leave it overnight.
A shortcut version
You can skip making a cookie crumb crust with butter and simply layer whole biscuits on the base of your dish.
Decoration ideas
- In the picture above we piped homemade marshmallow fluff on top of the tart and torched the tips with a kitchen torch.
Not only does it look fancy, but you will fill the house with the joyful smell of toasted marshmallow.
- Dollop or pipe whipped cream on top.
- Sprinkle with cookie crumbs.
- Scatter with mini marshmallows.
- Dot large marshmallows on top and toast with a kitchen torch.
- Leave it plain.
Storage suggestions
To keep the tart fresh, you can store it in the fridge for up to 3 days. Simply cover it with cling wrap, foil or place it in an airtight container.
Not suitable for freezing.
