What goes into the recipe
- custard powder- this is the key ingredient that makes these: yellow, pillowy and delicious. Melting moments are very similar to these but aren't made with custard powder.
- icing sugar- using icing sugar to make these biscuits has some awesome benefits. you don't need to drag out the stand mixer, because they can be kneaded by hand, getting the butter easily into the sugar and custard powder to make a dough. Literally by hand- you need to get your hands into this mixture, as the butter will emulsify with the warmth of your hands, but won't do that with a wooden spoon!
- butter- you can't swap this for margarine or anything similar and have the same results, this needs to be butter!
- vanilla- extract works best in this recipe. Although there is already vanilla in the custard powder, it's essential to add this to help with the vanilla flavour. If you don't have vanilla extract it swaps for a teaspoon vanilla essence.
- flour- this is plain flour, and we are holding off on adding it at the start as we need to get a dough almost done first, then the flour helps to complete the dough
- icing sugar- not icing mixture! Icing sugar. You don't need to sift it, but you can if you want to!
- milk- not much, just enough to give it a creamier texture.
- butter- not margarine. Unsalted butter is the best for this.
- boiling water- just to emulsify the sugar and get everything smooth. Using boiling water means that the icing sets when it is at room temperature, meaning the biscuits will stay stuck together!
- vanilla extract- because nobody wants icing without flavour. Vanilla is the best to use for this icing, but you could also try lemon or almond, both work really well (lemon juice also works!).
- food colouring (optional)- I used red for this to give a bright pink, but they also look cute with blue, green or orange icing!

Expert Tips and FAQs
No! Although visually similar, yo-yo biscuits use custard powder in the dough to create the biscuit dough and have a softer, crumblier mouth texture.
Once cooked, yo yos will last 3-5 days. The best option for storing is the fridge as the icing contains butter and milk and therefore is prone to running if kept out of the fridge. An airtight container is your friend!
You don't need to for this recipe. There is no need to cream butter and get your beaters dirty for something this simple.
