Twix Chocolate Layer Cake

You guys! I’m back with a very special chocolate cake recipe. Hands up if you are a chocolate lover? I have both hands raised. But it’s not just chocolate that I am crazy about. I also love caramel and Twix bars. This cake is my new best friend. Not only does it look impressive but it tastes AMAZING! We’re talking two layers of thick and soft chocolate cake, covered in sweet and creamy caramel frosting – made using homemade caramel sauce. The final touch is an avalanche of chopped Twix bars, crushed shortbread cookies and more salted caramel.

Twix Chocolate Layer Cake

If you have a birthday coming up or a special celebration, you have got to bookmark this cake. Not only will it wow your family and friends but it’s not complicated. The chocolate cake is a simple mix cake that can be split into two cake tins. And while the caramel frosting is made using homemade caramel sauce,  you could use the store-bought kind if you are tight on time. However if you are feeling adventurous, give homemade caramel a go, it really is buttery-licious.

Twix Chocolate Layer Cake

Once you have eaten half the frosting, oops I mean frosted the cake, you can then pile it high with all your favourite things. Be sure to pick up a few extra Twix bars so you can nibble on them as you decorate (that’s not just me is it?). I seriously LOVED this cake. I went back for seconds and had to demonstrate serious restraint not to go back for thirds. Moderation right? I’m dubbing it the perfect chocolate cake. Growing up, I only ever wanted chocolate cakes for my birthday and even though now I am partial to ice cream cakes, I think this one will go straight to the top of my birthday wish list.

A delicious layer cake that will delight any Twix lover. Soft and fluffy chocolate cakes with a creamy caramel frosting, topped with chopped Twix bars, crushed shortbread cookies and homemade salted caramel sauce!


Chocolate cake

  • 2 cups (280 grams) plain flour
  • 1 cup (80 grams) cocoa powder
  • 1 teaspoon baking powder
  • 1 and 1/2 teaspoon baking soda
  • 1 and 1/2 cup (300 grams) caster sugar
  • 1/2 cup (90 grams) brown sugar
  • 1 cup (240 ml) buttermilk
  • 3/4 cup (180 ml) vegetable oil
  • 2 teaspoon vanilla extract
  • 3 large eggs, room temperature
  • 1 cup (240 ml) hot water

Caramel frosting

  • 1/2 cup (115 grams or 1 stick) unsalted butter, softened
  • 2 and 1/2 cups (325 grams) powdered or icing sugar
  • 1/2 cup (120 ml) [url]salted caramel sauce∞[/url]
  • Twix bars, chopped
  • Shortbread cookies, crumbled
  • Extra caramel sauce for drizzling


  1. Preheat your oven to 360 F (180 C). Grease and line two 8 inch round cake tins. In a large mixing bowl, sift the flour, cocoa powder, baking powder and baking soda. Then add the sugars. Whisk together. In a separate mixing bowl, add the buttermilk, vegetable oil, vanilla and eggs. Whisk together.
  2. Add the wet ingredients to the dry ingredients. Start to fold together, slowly pour in the hot water, and continue to mix until all the ingredients are incorporated. Divide the mixture into the two cake tins and bake for approximately 30 minutes or until a skewer inserted comes out clean. Leave for 10 minutes before gently removing the cakes from their tins and leave them to cool completely on a wire rack.
  3. To make the frosting, add the butter to a large mixing bowl and beat until smooth and creamy. Add the powdered or icing sugar and beat until smooth. Add the caramel sauce and continue to beat until creamy.
  4. To frost the cakes, you may need to trim off the dome of the cakes using a large serrated knife or a cake cutter. Then, add half the frosting to the top of one chocolate cake and then add the other chocolate cake on top. Frost with the remainder of the caramel frosting. Finally, top with chopped Twix bars, crushed shortbread cookies and drizzle with any extra caramel sauce.

    I’ve never seen cake batter that looked like this. It was like soup, and I was certain I’d done something wrong. I definitely wouldn’t recommend making a make a layer cake. I put mine in a 13 x11” pan and that was perfect. If I’d made a layer cake the top layer would have slipped off the bottom layer. I love Twix bars but I’d also forgo putting them on top of the cake. The cake called for shortbread cookies on top which would have been nice and I’d drizzle some melted chocolate over the top. I froze half of mine because my husband didn’t like it. It was so damp I had to leave the it loose in the storage pan so it could evaporate and dry out. The recipe said it was rich but not too rich. I love my sweets but I’d only eat a brownie size portion. Lastly, just use a regular chocolate cake mix.

    How should I store this? Refrigerator or room temperature?

    Hi! This cake looks amazing! I am considering making 3 6 inch cakes instead of the 8 inch cakes you mentioned. Do you have advice for temperature and bake times? Thank you!!

    It was very easy to make but I had to add more butter than listed to make my icing

    Excellent recipe. Tried an oil cake for the first time .it turned out great ! Also caramel cream icing is just, Wow!
    Thank you !

    I followed the directions for the icing and ended up having to doctor it with extra butter, sugar and whipping cream because the butter, sugar and caramel only instructions just made a crummy mess. More sugar than the butter would cream into!

    I tested the icing before going on the cake but hopefully it goes well with the cake as I didn’t have time to toss what I had and retry!

    Still excited to try. Just hope others are wary that the icing might need extra love

    “I made this once for a family gathering and now everyone insists that it be at every gathering! It’s so easy; you use a box cake mix! For chopping the chocolate bars, I put them in the freezer, then hit them with a hammer while still in the wrapper”

    Thanks for the wonderful recipe! I’m making this for my daughter’s first birthday party, can’t wait to try it! 🙂

    One question though. I only have one cake tin. Is it okay if I leave half the batter on the counter while the other half is in the oven, or should I put it in the fridge?

    Sandra Henslee — June 11, 2018 at 11:42 pm

    Could you please tell me what kind of cocoa powder you used.
    Was it a dark chocolate or regular powdered cocoa?

    Tommy — April 30, 2018 at 2:51 pm

    Am I reading that right, I need to mix the caramel into the icing? Won’t that make the icing go brown, how are you keeping the icing white?

    Question… in the ingredients list there isn’t any eggs but in the comments someone asked about an eggless version. So my question is how many eggs are needed since they aren’t listed? Thanks in advance. I am making this for my sons bday tomorrow.

    Meagan — January 26, 2017 at 1:26 pm

    Hi there! Amazing looking cake. Would it be possible to substitute the caster sugar with powdered? And how many days would u say this cake would stay fresh? Thanks in advance!

    • #
      Jess Holmes — January 30, 2017 at 2:41 pm

      Hi Meagan, thanks for your comment. I wouldn’t using powdered sugar in the cake but granulated sugar is fine. The cake stays fresh for 2-3 days.

    Rain — June 5, 2016 at 10:06 pm

    Absolutely gorgeous, decided to make it for a friend’s 21st and it was a lot easier than I was expecting for such a beautiful cake!! The chocolate cake is one of the lightest, fluffiest and richest chocolate cakes I’ve had in a very long time, and the icing was almost too sweet in the best kind of way. I’m always nervous about trying new recipes for occasions like these in case it doesn’t turn out well, but I’m very happy I decided to try my hand at making this. Will definitely be breaking the recipe out again c:

      Oh I am so glad to hear that Rain! Thanks so much for the very kind feedback. I love this chocolate cake recipe as well and I am so glad you enjoyed it with the caramel icing! 🙂

    I would love to know what mixing method you used? Looks delish!

    • #
      Jess Holmes — May 15, 2016 at 3:12 am

      Hi Michele, thanks for getting in touch! Since this cake is made with oil rather than butter, you simply mix it together with a wooden spoon or spatula – so easy!

    When I was younger I never appreciated the beauty of the Twix bar – what was with the weird biscuit in there? Now, as an adult who can’t eat Twix bars I wish I had taken full advantage of their delicious chocolate, caramel, shortbread combination. What an absolutely gorgeous cake creation. I can’t wait to make it for my Mum’s birthday 🙂
