You will love this rich, easy and slightly tart chocolate and raspberry cake! This easy chocolate cake doesn't need a mixer, and the raspberry ganache filling inside is next level. I finished it off with a super easy chocolate ganache drip for the drama.
This cake isn't one I would usually do, as I'm usually a 'no fruits allowed!' when it comes to chocolate. But when a friend of mine commissioned a cake from me for her birthday and requested a raspberry chocolate cake, I started to come round to the idea. And thank goodness, because this is DELIGHTFUL.
How to make a chocolate & raspberry cake
Usually when it comes to chocolate cake, I like a dense, fudgy and super dark cake (like this one over here!). I felt if I was combining the more delicate taste of raspberries though, I didn't want a cake or frosting that was too heavy and would overpower the raspberries. I went with a much lighter crumb cake, based off of the chocolate cake from Dominique Ansel's latest book.
In this book Ansel mentions a way to add fruit to a ganache, where you puree fruit, strain it, and add it to your usual chocolate ganache. This is what made me realise I had to make this cake again for the blog because that ganache is so tart, sharp but still has a great chocolate base. Once I piped the raspberry ganache on to the cake, I added more raspberries on top. Not only do you get that great burst of colour when you slice into the cake, but you also get even more of that tartness when you bite into it.
I am usually a fan of a Swiss meringue buttercream, but decided to try out a French buttercream after seeing it mentioned in the Ansel book and the new book by Claire Saffitz, Dessert Person. Instead of making the meringue base with egg whites, this buttercream uses egg yolks. It gives you a much more custard like buttercream and felt very rich, so using it as part of a naked (ish) cake felt like the perfect combo.
Expert Tips & FAQs
For this drip I use an equal part combination of double cream and chocolate. The chocolate I used was 51%, but if you were to use one that is more 70-80%, you would need to use a tablespoon or more of cream as otherwise the ganache will be too thick and not drip.
I microwaved the double cream and chocolate together in a bowl, stirring every 15 seconds until the chocolate was melted. Then I left it to the side, occasionally stirring until I had the right consistency. If you used it right away, it would be far too thin and would run all the way down your cake. While you're waiting for the ganache to set a bit more, make sure to keep your cake in the fridge. A cooler cake is going to make this a lot easier! You can test the ganache on the side of the bowl to see how far it drips down. I like to put my ganache in a piping bag but you can also just use a spoon. I made the drips all along the side of the cake, then pouring the rest of the ganache on the top of the cake. Use an offset spatula to smooth out the top and you're done!

Make the Chocolate Drip
- Put the chopped chocolate and double cream in a bowl and microwave in 15 second bursts until the chocolate is melted. Keep the side and keep checking the texture of the ganache until you can drip it down the side of a bowl and it doesn't continue running down.

- Using an offset spatula, cover the top of the cake with the buttercream. Bring it around the sides and then using a bench scraper, smooth of the sides of the cake. Put the cake in the fridge to stay cool.
- After 15-20 minutes, drip your ganache along the sides. Finish off with raspberries on top.
