Chocolate and Blackberry Layer Cake

Autumn is definitely here! It’s suddenly a lot cooler outside, so I feel it’s certainly time to start having some autumnal recipes on the blog!!

Blackberries are one of my favourite berries to use this time of the year. They are also so versatile and easy to use in so many types of desserts and bakes! In this recipe, I’ve used the blackberries to make a coulis as well as a blackberry cream cheese frosting.. the tanginess of the blackberry works so well with the richness of the chocolate, it’s a match made in heaven.. in my opinion anyway!!


  • Dark Chocolate
  • Eggs
  • Caster Sugar
  • Cocoa Powder
  • Plain Flour
  • Salt
  • Baking Powder
  • Oil
  • Buttermilk
  • Blackberries
  • Cream Cheese
  • Unsalted Butter
  • Icing Sugar


Making puree is so easy to do.. All you need is a blender or food processor. You can use frozen or fresh blackberries for this. Place them In the blender with 1-2 tbsp water and blend! That’s it! If you want to sweeten it, you can add a 1-2 tbsp. caster sugar to the mix. If you want a super smooth puree, you can strain the puree through a fine sieve, but I personally like the pips throughout the mix, it adds some texture to the cream!
