My 25th Birthday Cake!

A chocolate explosion birthday cake for my 25th birthday!

Happy birthday to me!
So today, 20th October, is my birthday! This year, I have turned 25. I’m not entirely sure how I feel about this, so I decided to bake myself a bit of an explosion chocolate cake. FYI, it was heavenly.
I love baking cakes and such, but fondant is a bit of an effort for me, so I always prefer to do a cake like this for myself. I love making them as its easier for me, its delicious, and I think they look awesome. Yes, its a little sad to have to bake your own birthday cake, but I decided to make this one two days before so I could relax on my actual birthday!
I merged a few recipes together to create this one, as I was really in a chocolatey mood. I used a cute silver ‘Happy Birthday’ cake topper from Iced Jems for the ‘Happy Birthday’ sign, and I thought it just made it that bit more special. To some, it could look messy, but I love it.
For the Recipes
- For the chocolate sponges I used the cake part of my Oreo drip cake recipe.
- For the chocolate buttercream I used the buttercream from my chocolate cupcakes recipe.
- For the chocolate drip I used the the same method as my Oreo drip cake recipe.
- For the bark decoration I made a half batch of my chocolate bark, with sprinkles on.
- I then used some Rolos, Chocolate orange slices, Cadburys Flakes, extra buttercream leftover from decorating, and some Iced Jems sprinkles, and then a silver ‘Happy Birthday’ cake topper, and I used a chocolate number mould to create the 25!
For the Method
- I followed a similar method to my Oreo drip cake recipe, and then inserted some chocolate bark shards, and randomly added things on to get a cool style. Its one of those things you don’t really want to think about too much. Just place and roll with it!
These sort of bakes really are an experiment from the beginning, and you learn what you like as you go!
I hope you all love the cake as much as I did, and if you ever want to make your own version then do show me yours by commenting on my Facebook posts, or tagging me on social media like Instagram with #janespatisserie!

I am so delighted to have discovered your blog. Such a talent!! Making the Oreo Drip cake for my daughters birthday this weekend following the success with many of your other recipes.
Amazing cake jane i liked it very much. i have a question
How does the buttercream recipe for your cupcakes differ to cover this cake? or is it the same amount?
thank you!
Hi Jane
for the chocolate buttercream, did you use the same quantities as your receipe for the chocolate cupcakes or do i need more as its quite a big cake?
I made a big batch as I was baking other stuff at the time as well, but you would probably need at least double!
HI Jane, what size isn’t this cake? Is it an 8inch? If I wanted to make a 10inch own much would you add to the ingredients?
This is an 8″, and using my Oreo Drip Cake recipe as linked. To scale up to a 10″, you need to add on another 2/3 of the recipe, and split between three tins to bake! x
Hi Jane, do you think the drip will work with Cadbury’s chocolate! I have 850g bar and don’t want to buy anymore unless I have to. Thank you.
Oops, exclamation mark is not supposed to be there, it is a question….
I’ve never used Cadbury’s as a drip before, but it might be thicker than regular dark chocolate when melted because of the other ingredients. Its definitely worth a try, but keep an eye on the oil you add!
THANK you, which brand do you use for your drip – cooking chocolate the one you find in baking section or eating chocolate the one in confectionary?
I tend to use just regular supermarket own chocolate which you can get down the confectionary isle, or a use a brand called Callebaut. x
I’ve just attempted to make this. My buttercream kept dragging the sponge away despite putting on a crumb coat and leaving it for 2 hours. Please can you give me some tips? Thank you.
Sounds like your buttercream was far too firm. Try making it slightly softer with 1-2tbsps boiling water.
Hi Jane, I am thinking of attempting this cool cake. Could you please tell how you make your chocolate bark stand on the cake – do you push it into the cake ?
Yes basically you have to carefully push them into the cake! Make the chocolate bark reasonably thick so that it doesn’t break, and wait till its completely solid and push in!
Melt chocolate in a tin I sometimes use both dark and milk add the hundreds and thousands and put it in the
Fridge to set add on top of cake
Hope I helped
How does the buttercream recipe for your cupcakes differ to cover this cake? or is it the same amount?
thank you!
I would use about x3 the amount.
