This has been my favourite cake ever since my mom discovered the recipe when I was about 14 (and I have had my fair share of delicious cakes). It’s very chocolatey, yet the blueberries balance it out perfectly. Because of its deliciously gooey consistency it’s more of a tarte than a cake, but it is fairly easy to make. I can only recommend trying it at least once! You will not be disappointed.
If you are allergic to gluten, this recipe is very easily adjustable to that since it uses next to no flour, so the consistency and taste will not be affected.
