Yo-Yo Biscuits
Yo-Yo Biscuits are a classic Aussie treat that have stood the test of time, and for good reason! With their buttery, melt-in-your-mouth texture and a zesty orange cream filling, these biscuits are pure nostalgia. Perfect for a morning tea, an afternoon pick-me-up, or just because—you won’t be able to stop at one!
Ingredients
Biscuits
- 125g butter, at room temperature
- ½ cup caster sugar
- 2 egg yolks
- 1 teaspoon vanilla extract
- ¼ cup custard powder
- ¾ cup plain flour
- ¾ cup self-raising flour
Filling
- 50g butter, at room temperature
- 1 cup icing sugar
- 1 teaspoon boiling water
- Finely grated zest of ½ orange
Instructions
- Preheat oven to 180℃ (160℃ fan forced). Line 2 baking trays with baking paper.
- Cream butter and sugar in a bowl until light and fluffy. Add egg yolks and vanilla and beat well to combine.
- Add custard powder, plain flour and self-raising flour and mix until a dough forms. Roll heaped teaspoons of mixture into balls (I weigh each ball and mine weighed about 18g each). Place onto prepared trays leaving a little room for spreading. Using the back of a fork, lightly squash each biscuit to mark the top.
- Bake in the oven for 10-12 minutes or until biscuits move when pushed gently with your fingertip. Remove and transfer to a wire rack to cool completely.
- Meanwhile, to make the filling, combine butter, icing sugar, boiling water and orange zest in a bowl until well combined. Spread half of the biscuits with the orange filling cream (be generous) then sandwich together with the remaining biscuit halves. Allow to set before serving, if you can wait!
Notes
- MEASUREMENTS
We use Australian metric measurements. 1 teaspoon = 5ml, 1 tablespoon = 20ml and 1 cup = 250ml
We use free range extra large size eggs. Each egg weighs approximately 59g. - ICING SUGAR
You can use icing sugar mixture or pure icing sugar here. For a softer filling I use icing sugar mixture but if you prefer a harder centre, use pure. - MAKE AHEAD
Store in an airtight container at room temperature for up to 1 week. - SWITCH UP THE ICING FILLING
You can play around with the icing so the biscuits suit your flavour and/or theme! Try these different ideas in place of the orange zest.
-
- Lemon – omit orange zest and use 1/2 teaspoon lemon juice
- Passionfruit – omit orange zest and water and add the pulp of 1/2-1 passionfruit
- Coloured – omit orange zest and add a few drops of food colouring to suit your gathering or theme. i.e pale pink for a girl baby shower, pale blue for boy baby shower, pastel colours for a high tea or children's birthday etc
