Cadbury Crunchie Cake with a twirl Recipe

Last updated on May 5th, 2024 at 03:06 pm

Today is Mr P’s birthday and what better way to celebrate it than to surprise him with a new recipe for his birthday cake. I have been thinking of what kind of cake I wanted to make him for a few weeks now. What it came down to was putting his two favorite candy bars Cadbury’s Crunchie and Twirl together with his favorite cake, coffee cake. Mixing these together, I went with a dark chocolate frosting as there was clearly already enough sweetness to this recipe. It turned out delicious. Not the easiest to photograph on a dull and rainy day but at least you will get the idea below. It looked much better in person. I even got a “Wow Crunchie Chocolate Cake” from the kids which made me feel good when I brought it out at dinner tonight.

Birthday Celebrations

I absolutely adore celebrating birthdays. It’s a time to really spoil that person and celebrate their life they have had so far. I set the table and prepared Mr P’s favorite meal and then I piled the presents at the end of the table to taunt him while he ate. For some reason he ate his dinner and dessert faster than normal tonight. It’s his old age starting to kick in…shhh don’t tell him I said that or maybe the fact that he is really just a big kid after all and wanting his presents?

Birthday Cakes

As you get older the best bit about birthday’s is still the cake right? It’s something everyone can enjoy together, and I love to make them for my family to really make them see how special they are to me. If we don’t need a big cake (although how often does that really happen?!) then I still make the effort with some cupcakes – I love these pumpkin cupcakes with cream cheese frosting and salted caramel drizzle – or treats.

If you prefer a gluten free birthday cake option then you could always try my 4th of July watermelon cake, or the ultimate Rice Krispie tower cake for something completely different. You can find more free-from recipes here.

Chocolate Crunchie Cake

What I love most about this Crunchie Cake recipe, besides how easy it is to make, is the fact that the flavors all really go well together. It’s not too sickly if you stick to one slice and not three at a time. It paired nicely with heavy cream for Mr P and vanilla ice cream for me. I think cake should always be served with ice cream, and next time I think I’ll try it with Jammy Dodger Marshmallow ice cream for that extra indulgent kick.

How Do You Decorate A Cake With A Crunchie?

My favourite part about decorating cakes is that there are no rules. You can do whatever you like! I prefer to crush up my Crunchies (and Twirls) and scatter them over the top of the cake, and then loosely stack some larger pieces on the top – just watch out for the kids pinching those bits! If the messy look isn’t for you then you can chop the Crunchie into chunks and place them in a circle around the edge or create a spiral.

Don’t Like Crunchie?

If the idea of a honeycomb cake doesn’t quite make the cut for you, then it’s easy to change it up. You can just have a Twirl cake by leaving he Crunchie off completely – or replace it all with broken up bits of your favourite chocolate bar making a completely unique birthday cake with the things you love.

  1. This looks simply amazing! It’s my birthday in a couple of weeks, I’m going to leave this recipe lying around in the hope someone will get the hint!!

  2. Oh my gosh this looks INCREDIBLE! Wow, wow, wow-please vlog this next time too! Hope hubby had a super birthday. The photography and styling is so on point and I LOVE the new look of your blog too, gorgeous. Sorry for the all the shouting, I’m excited and crunchies are my all time fave choc-not had one for about a decade-shameful! Happy New Year!

  3. Had I known this was the cake you had some leftovers of, I’d have hunted you down! Serious crunchie love over here. Oh I can’t wait for the kitchen to be finished so I can give this a go x

    • It’s super easy to make try it and let me know what you think. Double the crunchie amount that you put into the cake if you really like it. 🙂 Hunt me down I made way too much would have given you half of it.

    • Oh thanks I think it’s gone down hill lately as I have been really slacking on practicing and taking the time to set things up and work on them. I feel like I am rushing everything so my new goals are to simplify life and work slower and enjoy it all more.

  4. I love the look of your vamped up coffee cake. And the decoration… It looks like something I would love to give a wee blast in the microwave and enjoy with a massive scoop of ice cream. Possibly honeycomb ice cream!

    • Oh yes we had it with ice cream that was the only way and Hubby with his favorite heavy cream. It’s got the crunchie’s inside the coffee cake too it was delicious. Flavors mixed perfectly. Thank you.

  5. Made this for Mum’s birthday (she’s a huge fan of coffee cake and Crunchies) and it went down a treat! I’m not a huge fan of coffee cake and my parents aren’t huge sweet tooths, so it’s rare to find a recipe we all love!
