Yo-Yo Biscuits (custard cookies)

These Yo-Yo Biscuits will absolutely melt in your mouth. They are the most deliciously, crumbly and soft biscuits ever. Try them and fall in love!

If I could choose any biscuit in the world to have with my afternoon cup of tea, I’d totally choose yo-yo biscuits. Hands-down. They are just the yummiest little bites of perfection!

Yo-Yo Biscuits

When I was little Mum would sometimes take us to a market and we’d buy yo-yo biscuits off an older lady there. It wasn’t like the trendy farmers markets that are around today though – nope it was just a tiny market in an old shed! Anyway, the yo-yos definitely made the trip worthwhile.

So what gives yo-yos that deliciously soft, crumbly, shortbread-like texture that totally melts in your mouth? Well that fabulous little combination of butter, sugar and flour of course! But yo-yos have one extra special ingredient that makes them even yummier than other biscuits – custard powder. Yep, custard powder is what makes yo-yo biscuits taste sooooo good and it’s also what makes them different from melting moments! Melting moments are super similar to yo-yos (in fact they often get confused as being the same thing). They too, melt in your mouth and are ridiculously yummy, however, they’re made with cornflour instead of custard powder. You can find my recipe for Passionfruit Melting Moments here. So there you go, a little bit of biscuit trivia for your Monday!

When you make yo-yos, make sure you roll your balls of mixture quite small. Remember that you’ll be eating two of the biscuits at once, so you don’t want them to be massive (well actually maybe you do!). I made that mistake a few weeks ago when I made a batch of Monte Carlo biscuits and each one was about the size of a full meal… not that I was complaining!

How to make Yo-Yo Biscuits…

You can of course make your yo-yos with a classic white filling. But I’m a self-confessed girly-girl, so there was no way my yo-yos weren’t going to be pink!

  13. Tegan says:

    The look absolutely gorgeous. I haven’t heard of Yo-Yo Biscuits before, however I wonder if that is because I just thought they were all melting moments lol!

    1. Bake Play Smile says:

      Thanks so much Tegan – you’ll love a yoyo!

  14. I love these biscuits, but I never knew they were called yo yo’s! I just thought they were a version of shortbread biscuits, whoops.

    1. Bake Play Smile says:

      They are a version of a shortbread, but yep definitely called yo-yos! Hope you like them 🙂 xx

  15. Those look absolutely delicious! And the way you write about them and describe them? My mouth is positively watering!

      Oh thank you so much xx

  20. Smaggle says:

    These look amazing! So perfect… I can never yoyo biscuits to look like this! I think I may have to get a Thermomix after all!

    1. Bake Play Smile says:

      Oh thank you Carly! Hehe these are just as good without a Thermomix I promise!

  21. These look fantastic! Custard powder is a real secret of classic baking 🙂

  22. Ashley Stevenson says:

    I was wandering if you can help I’m desperate to get these biscuits right, both my biscuit mix and icing mix are too dry what am I doing wrong?

    1. Bake Play Smile says:

      Hi Ashley, the very first thing I would suggest is to spoon your flour into the measuring cup (rather than scoop it) and then use a knife to wipe off any excess. One of the most common problems with baking is over measuring the flour (and this would definitely make your dough dry). Also, make sure that you’re using room temperature butter. For the icing – measure the icing sugar the same way as the flour and if it’s still too dry, add a little more lemon juice. Hope that helps!

  23. Noelene says:

    Years ago I use to make melting moments for a very popular coffee shop and they were always the first ones to go. I totally agree with the “custard powder” idea and even find it great to include it when making birthday cakes as a basic cake recipe. I’m always asked for the recipe and yet its so easy and comes out light and fluffy each and every time I make it.

  24. Cynthia says:

    Hi Lucy just wondering Yoyos seem to sit in jars at cafes etc for a while. How long would be ok to store them in an airtight container?

    1. Bake Play Smile says:

      Hi Cynthia, they should be fine for 4-5 days in an aright container! If they last that long.. that is!! xx

  25. Abbey says:

    Is there a secret to getting perfect looking yoyo’s that don’t crack? They still taste amazing however I can’t get them looking perfect!

    1. Bake Play Smile says:

      Hi Abbey, I think the main thing is to make sure that your oven isn’t too hot!!

  26. Amanda says:

    I was so excited to try these as I love your recipes but I had a lot of trouble with the icing. It went quite crumbly with the icing sugar and butter and then more like a dough once all ingredients added. Do you know what I might be doing wrong? The wrong icing sugar or something? I’m making in the thermomix. Thanks =)

    1. Bake Play Smile says:

      Hmm that’s very weird! My guess is it’s the brand of icing sugar or butter used. That being said icing sugar mixture is much ‘softer’ than pure icing sugar so perhaps give that a go! Or add a little extra lemon juice! Good luck xx

      1. Amanda says:

        Thanks so much for your reply. I still made them, just put on the icing with my fingers and flattened it out (haha!) and omg they are DELICIOUS!!!!! Absolutely the best yoyo biscuits I’ve ever had. Thank you for such a wonderful recipe!!!

        1. Bake Play Smile says:

          Hahaha well that’s as good as any way! So happy you liked them! It’s actually time I made another batch!

  27. Lorraine Reynolds says:

    These look great, but I can’t seem to print off the recipe. I’ve clicked the print button about 10 times and nothing.

    1. Bake Play Smile says:

      Hi Lorraine, we’re currently in the process of having this fixed! It prints fine for me on Safari (but not on Chrome), so if you try another web browser it should be fine!

  28. Natasha says:

    I also feel like the icing comes out too dry. I measured it out to the gram but had to add alot more butter and lemon juice to make it more workable.

    1. Lucy Mathieson says:

      Hi Natasha, it can be a little tricky! I’ve found that certain brands of icing sugar and butter make a difference – it’s just a matter of playing around until you’ve got the right texture. xx

  29. Sarah says:

    My English granny used to make Yo-Yo biscuits, but instead of sandwiching two biscuits together with icing, she’d put choc chipsin themix, and serve them as single biscuits.

    1. Lucy Mathieson says:

      Oooh that’s a fantastic idea!!! xx

  30. Jacquie says:

    Hi how far in advance can the biscuits be filled with the passion fruit filling ? Also can the biscuits be frozen (unfilled)?
    Thanks

    1. Lucy Mathieson says:

      Hi Jacquie, they’ll be fine for a few days filled (in an airtight container) but will soften over time. I would freeze the uncooked dough rather than the biscuits. xx

  31. Darren says:

    Hi there, my biscuit mixture is coming out way to soft, you can’t form a ball with it, it’s a bit mushy. I measured everything exactly and use a stand mixer. 2 attempts with same result. Do you no why this happening?

    1. Lucy Mathieson says:

      Hi Darren, it could be either the brand of ingredients used or the temperature of your kitchen. Just pop the mixture into the fridge to firm up a bit and then roll into balls. xx
