The ultimate Twix Cake is here! Two layers of moist chocolate cake covered in a creamy chocolate caramel buttercream with plenty of Twix Bars and extra caramel sauce.
Calling all Twix lovers! 💜
The ultimate Twix Cake is here. We’re talking two layers of super soft and super moist chocolate cake covered in a thick chocolate caramel buttercream, with chopped Twix bars both in between the layers and on top.
It’s a truly choco-licious treat!
If you’re on the hunt for a chocolate layer cake that will wow a crowd but is actually surprisingly easy to make, this is for you! Let’s talk chocolate cake. This is one of my all-time favourite chocolate cakes because of it’s buttery flavour and stick-to-your-fork texture.
It’s actually a spin-off of my popular Chocolate Fudge Cake. It uses buttermilk for it’s light and soft texture and plenty of cocoa for its sinfully rich chocolate flavour. You could use it as a base for any special chocolate layer cake, but I think covering it in Twix and caramel is a very good choice 😉
Next, we have that luscious chocolate caramel buttercream. Not only does it have butter, sugar and cocoa in it, but a large helping of caramel sauce. You could make your own from scratch or simply buy your favourite kind from the shops. A nice, thick, store bought caramel sauce will work perfectly and save you oodles of time.
Once you cover the first layer of cake in buttercream, it’s time to scatter over some chopped Twix bars. Remember to buy a few extra because, if you’re anything like me, you’ll have eaten half of them before you’ve had a chance to decorate.
Frost the sides and tops of the cake, scatter over more Twix bars, and drizzle a little bit of extra caramel sauce. It’s makes one messy but oh-so-beautiful Twix Cake, perfect for birthdays, parties and the like!
TIPS FOR MAKING PERFECT CHOCOLATE CAKE
- I’ve made chocolate cakes with both oil and butter. Both work just fine but I do think butter gives this cake a beautiful, rich flavour.
- The recipe begins by creaming the butter and sugar together, so you will need an electric mixer. Just make sure your butter is at room temperature and not too cold.
- Buttermilk is an important ingredient in this recipe. If you don’t have any on hand, make your own but adding 1 tablespoon white vinegar to 1 cup of whole or regular milk. Leave for a few minutes and then use as normal. This substitution works just fine in this recipe.
- When you add the dry ingredients, try not to over mix the cake batter. This will ensure your cake is soft and tender.
- The hot water is important – don’t skip it! It helps the cocoa powder to bloom and makes a perfectly moist chocolate cake.
- The cakes will be ready when a skewer inserted into the centre comes out clean. Leave to cool completely before stacking and frosting.
TIPS FOR MAKING THE PERFECT CHOCOLATE CARAMEL BUTTERCREAM
- Temperature is everything. Make sure your butter is at room temperature. Cold butter won’t yield the same results. Your butter needs to be softened so it whips easily. But make sure it’s not too soft or melty by any means. It should be soft to the touch but still hold its shape.
- Beat the butter. The foundation of this chocolate frosting is making sure you beat the butter properly. Take your time and beat your butter until pale and creamy and smooth.
- Sift your sugar. I’m guilty on more than one occasion of not sifting my sugar but if you want the perfect buttercream, you HAVE to sift the sugar. It’ll ensure it’s light, fluffy and mixes well with the butter – no lumps. And same for the cocoa powder!
- Use your milk sparingly. The perfect buttercream has just the right ratio of butter, sugar and milk. Too much milk will make your buttercream too wet and runny, while too little, will make it too thick. Add a tablespoon at a time to ensure the correct consistency.
- Use good quality caramel sauce. You can use caramel sauce you’ve made from scratch or just buy your favourite brand at the supermarket. Try go for a thick, quality caramel sauce as the cheaper, runnier stuff won’t have that deep caramel flavour that you want in this dish.
- Don’t over beat the frosting. Once you add the chocolate, beat only until the frosting is melted and smooth – don’t over mix.

In a large mixing bowl, beat the butter with an electric mixer until creamy and smooth.
