Chocolate Blackberry Cake – Dark chocolate cake layers with blackberry compote and blackberry buttercream.
Chocolate Blackberry Cake
I’ve been wanting to make a blackberry buttercream for the longest time! My Gluten Free Cake with Mixed Berry Compote and Buttercream is one of my all-time favorite cakes. I knew the format for the compote and frosting would work great with blackberries but I thought the cakes would be too similar if I did a vanilla cake with the blackberry buttercream.
Instead, I went the route of my Dark Chocolate Strawberry Truffle Cake and made my favorite chocolate cake layers. The pairing of the sweet blackberry buttercream with the bittersweet chocolate cake layers is so decadent!
Bake Even Strips
You’ll see below that these chocolate cake layers turned out extra fudgy. I think this happened because I used new bake even strips. They did help my cakes to bake a little more flat, but it took an extra 10 minutes to bake and they turned out more brownie-like. Not sure I’ll sue them again on this particular chocolate cake recipe.
Here’s a quick assembly video to help as well:
Enjoy!

I don’t usually put a little layer of buttercream down before I add the compote, but it does make sense.. wouldnt it make it to slippery? Please tell me why you do that!! Thank you Karen
I do it so the filling doesn’t seep into my cake layers. I want it to be it’s own layer in the cake. If you pipe rim around the edge of the cake before placing a second cake layer on top, it will help prevent it from sliding around.
Hey Courtney! It looks like you are putting fresh blackberries on top of the compote in the video? Is this correct?
Yes!
Could frozen blackberries be used to make compote?
Would I be able to convert this recipe to use two 9-inch round cake pans instead?
yes.
