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.

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

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.

Do you use a small box of pudding mix or the large one?

Is it Angel’s delight people use ????

Is that what an instant pudding mix is called where you are? Not sure of your brands 🙂

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?

My 5 year old son and I are going to make this Sunday for hubby for Father’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 didn’t cook properly on the inside. Thank you in advance.

I can’t get the instant pudding in my town. HELP….. What can I do in replacement?


August 16, 2019

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

When it’s not listed in recipe it’s not meant to be used 🙂

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

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

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 🙂


September 28, 2018

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.

We made this on Monday. It was absolutely fantastic. My whole family loved it.

Absolutely easy to make and yummy to eat!

Straight in 🙂

Do you put cake mix in a tin or straight into slow cooker . Thanks

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.


July 6, 2018

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

Should the lava cake be gooey or runny. Opinions please

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 🙂


June 25, 2018

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 🙂


June 19, 2018

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

Chocolate pudding mix ?? Is that as in an Angel Delight please

Michelle Tonkin

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 to use a tea towel for this recipe please?

You can line it or greese it or use a cake tin etc
See here >> Slow Cooker Cakes

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


April 30, 2016

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
