ABOUT THE RECIPE
Marshmallow cake is really a slice, with a buttery shortcake base beneath a generous layer of strawberry marshmallow. The topping starts with a packet of jelly, beaten with icing sugar until pale and fluffy.
Cut into squares and served chilled, it’s a sweet addition to the afternoon tea table. Chocolate icing is an optional finishing touch for anyone who likes strawberry and chocolate together.

Ingredients
Shortcake base
115 g butter, softened
165 g caster sugar
1 egg
1 tsp vanilla extract
225 g plain flour
1 tsp baking powder
Strawberry marshmallow topping
1 × 85 g packet regular strawberry jelly crystals
1 cup water
300 g icing sugar
Optional chocolate icing
150 g icing sugar, sifted
15 g cocoa powder, sifted
15 g butter, softened
1–2 Tbsp hot water, as needed
Method
1.
Preheat the oven to 160°C fan. Grease a 23 × 33 cm slice tin and line it with baking paper, leaving some overhang so you can lift the cake out later.
2.
Beat the butter and caster sugar until light and creamy. Beat in the egg and vanilla. Add the flour and baking powder and mix just until a soft dough forms.
3.
Roll or press the dough evenly across the bottom of the tin. Bake for approximately 20–30 minutes, until lightly golden and firm in the centre. Leave it in the tin to cool completely.
4.
Put the dry jelly crystals and water in a medium saucepan. Leave to stand for 10 minutes. Bring the jelly mixture to a boil, stirring to dissolve the crystals, then boil for 5 minutes. Remove from the heat.
5.
Transfer to a large heatproof mixing bowl, add the sifted icing sugar and beat with electric beaters until the mixture is thick, pale, fluffy and holds its shape. It may take several minutes to thicken as it cools.
6.
Immediately spread the marshmallow over the cooled base. Leave until cold and set, this will take a few hours.
7.
Mix the icing sugar and cocoa with the butter. Add 1 tablespoon of hot water and stir until smooth, adding a little more water only as needed to make a thick but pourable icing. Allow it to lose any heat, then gently pour it over the set marshmallow and ease it to the edges without pressing down. Let the icing set before slicing.

THE TASTE TEST
So, was it worth making again?
The honest verdict after cooking from the 1979 page.
I enjoyed this, and the strawberry marshmallow was the highlight. It was yummy, although mine wasn’t quite as firmly set as I’d have liked. A little more beating may have helped. The shortcake base was quite thick, too, and I’d have preferred it a little thinner. A firmer topping and a little less base would have made a good slice even better.
SAMANTHA'S NOTES
Beat until thick
Give it time to set
Keep the base even
Use electric beaters until the marshmallow is pale, fluffy and thick enough to hold its shape. Beating builds the airy texture and thickens the mixture.
Allow at least 2 hours in the fridge before slicing, and longer if the topping is still soft. Chilling gives the marshmallow time to firm up; it should hold its shape when you lift out a piece.
Press the dough evenly into a 33 × 23 cm tin, taking care not to leave thicker patches. A smaller tin will give you a deeper base as well as a thicker marshmallow layer.
