    I couldn’t find a chocolate pudding so used a vanilla pudding instead. It came out as a 2 tone desert. When i eventually found a chocolate pudding i made it only for my kids say they prefer the vanilla pudding. I only cooked it 1 1/2 mins in a 1.5l slow cooker. This recipe is a total hit & i make it alot.

  2. This was absolutely amazing, all 3 of my kids loved it and there is leftovers for a couple of us tomorrow. Definitely making this again, I think I need a dessert slow cooker now lol

  3. Can someone please tell me what the difference is between an instant pudding and a self saucing pudding?
    Someone has told me not to add the sauce sachet or water so I am very confused now being I thought all pudding needed sauce =/

  4. There are a few people asking the same question that I did in regards to the pudding.
    Paulene confirmed with me that it is an instant pudding not a self sauce pudding and I found what she was talking about in the dessert isle near the jellies and mousses.
    It is a milk base dessert that would normally set like a custard… hope this helps somebody ๐Ÿ™‚

    Wow this recipe is absolutely amazing Jaclyn Wark. Easy to prepare and so yummy served with ice cream on a cold night. Rated 10/10 by our household ๐Ÿ™‚

  6. This was a disaster. I cooked it in my new Aldi 3 ltr. After 2.5 hours it was still not cooked. It was just like the sauce in a self saucing pudding, very little cake bits. I cooked it exactly as recipe states.

  7. Can you double the mixture as I have a 5L slower cooker and I would be feeding 9 people?
    Does the cooking time need to change?

  8. Made this last night. It tasted awesome. Next time I will use a bigger slow cooker though. My baby slow cooker (1.5lt) was not big enough to contain the chocolate ‘lava’…

  9. OMG this is the most delicious and creamy potato bake I’ve ever made . this will be a weekly new side dish in our house with everyone loving it . I did double the chorizo and bacon and added some spring onion to it but the flavour was incredible.

  10. Made a vanilla one with chocolate mousse with choc pieces done in my 5 litre sc cook for 2 hours on high turned out beautiful…

  11. Was pretty yummy!! And easy to make, tho mine took close to 3 hrs on high in my slow cooker and i used vanilla instant pudding, think id prefere chocolate next time…. overall pretty good!! ๐Ÿ™‚

  12. Made this lastnite but couldnt get cottees instant pudding mix so i used the areoplane desert mix. Was beautiful. Thanks

  13. Lots of people asking about tea towel method. For this recipe. Itโ€™s not in the recipe. But I would imagine it might get soggy without it ?

  14. I made this a week ago, beautiful. I used aeroplane chocolate dessert mix. Cooked in 5l slow cooker 2 hours on high. Spot on. ?

  15. My 5 year old son and I are going to make this Sunday for hubby for Fatherโ€™s Day / night desert. Son is so excited. Going to be cooking in my breville 3×2.5litre slow cooker how long should I increase the cooking time for please. As I have cooked cakes in the 6 litre one before and they have had a bit of crispy edges with a slight burnt taste so tried again on. lower heat and didnโ€™t cook properly on the inside. Thank you in advance.

  16. Hi, I am going to try this tomorrow, just wanted to know, Do you have to serve it as soon as it has finished cooking?

  17. This recipe gets a 10 /10 rating for me. It was soo easy to make and absolutely delicious. My family loved it. Will definitely make it again. Just as nice warmed up the next day with ice cream. Yum yum yum. ?????????

  18. I finally got round to making this last night after having bought the ingredients a while ago. Delicious and everyone loved it, I served it with vanilla ice cream. Easy to make too, I used a Betty Crocker Devils Food cake mix and Gregg’s Instant Dessert with Chocolate Chips, followed the packet instructions for both. I also used 4 Mars Bars :-), cooked in my 3L SC for 2 hours on high. I would make this again for sure.

    Absolutely mouth watering delicious!!
    So easy, the kidโ€™s loved helping and watching it form into a yummy gooey desert.

  20. I made this using snickers instead of Mars bars and ohhhhh yummm. I served with fresh whipped cream and it was delicious. Will certainly make again.
