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.

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

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!

Wow! I really need to get into the slow cooker cake revolution! xx

I am in awe of this one Lucy, such a simple, but such and effective idea.

Wow, this looks so decadent and gooey! I haven’t had mint aeros for so long!

I’ve spotted this so many times on my travels through your blog, I will have to make it when I finish my healthy eating kick as it looks lush.

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!

It’s kinda my new year’s resolution to make cake in my slow cooker – you are an absolute inspiration in this area, this lush cake is testament to that:-)

Oh my goodness, what a brilliant idea! I didn’t even know you could bake a cake in a slow cooker. Dessert just became so much easier!

I just love how gooey this looks! I bet your kids LOVE it when you pull out the slow cooker 🙂

It’s amazing what you can make in a slow-cooker! This cake looks delicious 😀

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…

I always knew you were a genius!! Wish we could get mint Aeros here – might have to drive to Canada specially!


This works really well as slow cooked cupcakes. 🙂


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

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

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