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!! 🙂

Other comments below suggest it will overflow in a 1.5L so best to go larger 🙂

Will this fit in a 1.5ltr slow cooker or is it best to do it in larger one?

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…

Jess you’ve left this on the wrong recipe 🙂 If you want to re add it to the chorizo potato bake for me I can delete this one then x

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.

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’…

Just made this today. Should have cut the mars bars up thicker but still tastes good x

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?

I’ve reviewed those Aldi 3L cookers on our review page and they are notoriously slow as I’ve reviewed. You’d need extra time in that cooker than normal recipe times state 🙂

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.

Im using a 3ltr slow cooker with a lid no tea towel

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 🙂

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 🙂

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 =/

I see some are saying they cooked it in a 1.5L
Or you could go larger like 3L etc

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

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.

do you need baking paper under the cake in the cooker?

Do you need tea towel under the lid for this?

Make the dry cake mix into a wet cake batter ready to cook as per the box or pkt instructions 🙂
Then use this mix in the slow cooker recipe
