So it is Good Friday and I am bringing you …..more chocolate! Well it can’t be avoided, this is the time of year for it after all. 🙂
This slow cooker chocolate and mint aero bubble cake is a cake with a difference as it is made in my slow cooker (3.5 litre oval slow cooker).
I decided to make a slow cooker chocolate and Mint Aero Bubble cake quite simply because I wanted to see the Aero Bubbles in a cake!
I have seen Maltesers and similar being used in traybakes (do make the Malteser traybake, it is delicious!) but I wanted these to go in a cake, not a no-bake or brownies.
I thought the cake would look great when sliced as you would see the green circles against the dark brown chocolate cake, as well as the bubbly texture of the bubbles against the velvety cake.
Well that was the idea anyway!
I saw in the traybake etc recipes that sometimes they froze the Maltesers or Aero bubbles overnight so they didn’t melt when baking.
I didn’t have the patience for that so just went for it.
Sometimes you just want cake then and there, am I right.
Ready to start baking! The base is lined with baking paper.
I would line the sides of the pot too to make it easier to get out!
This is what it looked like after 45 mins.
The edges are becoming firm and the Aero bubbles are melting! Just look at that rich chocolate colour, mmmmm.
Another hour later, after adding more Aero Bubbles in the centre.
The cake is starting to firm up.
Finished, after two and a quarter hours. Yummy, rich and fudgy chocolate cake topped with minty chocolate!

It’s delicious….Made one before Christmas and now things have quietened down a bit – I’m going to make another this weekend.
bakingqueen74 says
Glad you liked it!
lauren says
seen this earlier and have been out for the ingredients already it looks too delicious to not make it right now! haha
bakingqueen74 says
Excellent Lauren! Was it good? 🙂
brenda m nash says
I baked mine in a loaf tin with a drop of water in the bottom of the slow cooker. It was delicious and was very easy to slice because of its shape and depth
bakingqueen74 says
Great, sounds good Brenda!
Heather Stanger says
OMG I love cake – defo gonna try this maybe with different choc though – my slow cooker quite new and doesn’t need water but did you cook on high or low? X
bakingqueen74 says
Hi Heather, on high, they normally take about 1-2 hours. Good luck!
Nicki Pearce says
Hi, this cake looks great and I want to try it this weekend for a bake off at work! My slow cooker is 6.5l, so should I double mixture or leave it as the recipe states?
bakingqueen74 says
Hiya, it makes a big cake so I wouldn’t double it but put a cake tin in your sc and then you will get a round cake which looks better (for the bake off!).good luck!
Nicki Pearce says
Great thank you, I will give it a go!
Victoria says
Made this today.
This was my first attempt at a cake in the slow cooker so wasn’t sure what to expect but OMG IT IS AMAZING!!!!
Looks nothing like the picture as my bubbles melted but it sure tastes as good as the above picture looks.
I will be trying again.
bakingqueen74 says
Great, glad,you enjoyed,it!
brenda m nash says
Thank you. I will definitely visit the Facebook Page
brenda m nash says
I can’t wait to try this recipe. Love my slow cooker even more learning I can bake in it! Can you tell me if it’s possible to bake a Christmas Cake this way?
bakingqueen74 says
I haven’t tried it yet, but if you come over to the Facebook group Slow cooked wonders, some people have so you can get some tips!
SaRah says
Hey all could u use Maltesers instead of the aero bubbles ? Xx
bakingqueen74 says
Sure, chuck them in! Enjoy
emma says
This looks amazing, I’m going to try it tomorrow. I honestly didn’t know you could make cakes in the slow cooker! Thanks for enlightening me.
Rosalind Blight says
Have attempted this today. My house smells amazing only thing is my bubbles have all melted (and some crystallized) and the cake looks like it has little green craters all over it. Otherwise I am impressed as never cooked any cake in slowcooker before
Sharon says
I used aero bars (they were on offer) and it was gorgeous. We had it warm with ice cream 🙂 thank you great recipe
bakingqueen74 says
Great, glad you enjoyed it!
Soppy says
My aeros bubbles all melted I cooked it for 2 hours 10 mins why did they all melt ? Tastes nice though.
bakingqueen74 says
Hi, I guess it was just too hot, did you freeze them first? The slow cooker I used for this cooks quite slowly so mine stayed whole luckily
Emma says
I only have a rice cooker, will it work in that?
bakingqueen74 says
Sorry, no idea!
sam says
can you just use self raising flour instead of buying plain flour and baking powder? thanks
bakingqueen74 says
Hi Sam, yes, that would work too.
Fiona says
Would the malteezer cake be too crunchy inside ?? I was thinking of trying it today
bakingqueen74 says
Hi Fiona, they will melt and won’t stay crunchy, though I’ve not tried it myself. Enjoy!
michelle says
Hi. Im concerned that the greaseproof paper will catch fire. Do u put it on the bottom of the cooker? On top of margarine or just a layer of papee? X
bakingqueen74 says
Hi Michelle, it won’t catch fire,it is under a moist cake mixture. I greased the pot first with butter, and normally use baking paper which can go in the oven. Good luck with your cake if you try it!
Jo says
Found mine was still quite soggy in the middle
bakingqueen74 says
Hi Jo, I’d cook it for a little longer until no longer soggy. On low if it has started to look like burning, and with a tea towel under the lid to absorb the condensation.
Shrimp says
Hi, I just wondered how long the finished cake keeps please. And does it freeze well?
Looking forward to trying it – might try with Aero Orange Bubbles too 🙂
bakingqueen74 says
Hi there, mine didn’t keep for long as we scoffed it! It would last same time as a usual cake I’d say, so two to three days in a tupperware box or tin. I’m not sure about freezing I’m afraid as I haven’t tried it. Ooh yes, it would look nice with Orange bubbles! Good luck!
