    Slow Cooker Chocolate and Mint Aero Bubble Cake

     Slow Cooker Chocolate and Mint Aero Bubble Cake – a delicious chocolate fudge cake baked in the slow cooker with Mint Aero Bubbles! Baking in the slow cooker is so easy. The most popular recipe on my blog. Look in my Slow Cooker Desserts for loads more slow cooker cakes and bakes!

    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.

      I made it. It taste absolutely amazing. Although I had to use foil as I had no parchment paper and it was in for 3 1/2 hours. I forgot to freeze the aero balls and they all melted. It was worth it thankyou!

      Hi I love the idea of the slow cooked chocolate aero cake, however one of my daughters is gluten intolerant can I use gluten free flour for this recipe? Thank you

        Hi Karen, I don’t bake gluten-free so am not an expert at all, so I am not entirely sure if it would work. I do seem to remember an earlier comment here that someone made it using gluten-free flour though, perhaps you can have a look through and see.

      Mine’s been in nearly 4 hours so far and still not done lol. It’s smelling great but is full of craters for some reason. Long as it tastes good that’s all that matters though!

      I’ve never made a cake in my slow cooker and you’ve just given me a very good reason to give it a try! This is perfect for a post-school snack for my constantly hungry boys!

      Why have I still not tried to make a cake in a slow cooker? I think this will make a fantastic treat next time I have people over and my oven is full. I’m thinking of serving it warm with cream…

      Hello I would love to make this although I’d need an egg free recipe do you have one? Thanks x

        Hi Karmen, I’m afraid I have never had to replace eggs in my recipes so I don’t have a recipe without eggs I’m afraid. I think common egg substitutes in baking are mashed banana, apple sauce, chia seeds and so on. Hope that helps!

        Great to hear you made it Zoe! Times really depend on your slow cooker and how hot it is. Mine is on the way out I think!

      I’ve made the cake just waiting on it cooking 🙂 can you explain the ingredients, have you just given different measurements or is it 50g PLUS 2x tablespoons? Looking forward to trying it!

        Hi Charlene, if you are cooking using metric measurements just ignore the bit with tablespoons. I’ll add in some brackets to make it clearer. Hope you enjoy it!

      Hi there. What are the additional tablespoons of butter, sugar and cocoa for?

        September 11, 2015 at 5:45 am

        Hi Andrew, those are U.S. Conversions, for small measurements that don’t match the cup sizes, and are part of the total amount, eg third of a cup and two tablespoons. If you are using metric measurements, you don’t need to look at that at all. Hope that helps!

      Hi do you think you could use fudge pieces instead of the aero balls? 🙂

        Sure, use whatever you like! Some people have tried mars bars and Maltesers too, yum
