So we’re 21 weeks into our Slimming World journey and we’ve never tried overnight oats. That is until this week! We were looking through some recipes for them, and none really took our fancy, so we decided to ask our Facebook group.

Posh Overnight Oats - Apple Pie & Custard

We had some really interesting suggestions, and we’ll be putting some of them up here in due course. So excited! But until then we have these bad boys – “posh” layered Apple Pie & Custard overnight oats.

We use Sukrin Gold which is an all-natural granulated stevia sweetener alternative to sugar with zero calories. You can grab Sukrin Gold over onAmazon UK.

Sukrin Gold doesn’t have that strange after taste that a lot of artificial sweeteners do! It also shares the exact same sweetness and weight to sugar – which makes it really easy to substitute in recipes like these Posh Overnight Oats – Apple Pie & Custard.

If you are using a powdered sweetener, then please check how it compares to sugar. In some cases you’ll need to use less, as powdered sweeteners weigh less.

That being said you don’t have to use Sukrin – there are lots of other high quality granulated sweeteners available from the supermarket, such as Canderel Sugarly, and Natvia.

They’re not layered in the typical overnight oats sense, we found that sometimes the oats can stay a bit dry, so we decided to layer in a different way. First up we have an apple & cinnamon layer. There is some debate about whether a grated apple is a tweak or not – so we’ll leave that decision up to you. You could always cut the apple up real small instead.

Then we have the custard layer which is some fat free natural yoghurt, vanilla and sweetener mixed with Quark. We add Chia seeds in there to set the “custard” as they swell up when wet. Thus they set the “custard” layer & get a really nice set texture.

Wondering what Chia seeds are? They’re super seeds packed full of goodness & make you feel fuller for longer and can count towards your Healthy Extra B. This is why we only use 32g of Oats, so you don’t have to syn them. You can get chia seeds from your local supermarket or Home Bargains have them for £2!

I’d like to say a big thank you to all of our testers in our Facebook group. You guys have been brilliant, and we couldn’t have developed this recipe without you. Much love to you all x

  1. Having trouble finding syn free flavoured yoghurt as I am allergic to gelatine which is what most mullers contain any ideas?

    1. Hi Vickie, you can use plain yogurt, with vanilla extract and some sweetener & some custard flavouring. Lakeland do it apparently! Hope this helps x

  2. Hi, so there is two types of yoghurt in this – correct? Which fat free yoghurt would you recommend? thanks in advance

    1. Hi! Yes, there are two sorts of yogurt. You can choose any syn-free natural yogurt for the oats layer. (Greek yogurt can often be less acidic.) The recipes then suggests Muller Banana and Custard yogurt for the custard layer. (Alternatively,Aldi do a banana/custard variety for 0.5 syns and Lidl Milbona Banana/custard is free.)

  3. I love my overnight oats, this is by far my favourite recipe, so many flavours and it really does taste like apple pie and custard. Thanks

  4. I thought all flavoured fat free yogurts are now 1/2 run? Does that make the recipe 1/2sin now or would you just use unflavoured for both areas?

    1. Hi Donna
      You’d use the natural fat free yogurt in both. I’ve clarified this on the recipe card.
      Thanks for getting in touch!
