If you’ve not had a chocolate crunch before (where have you been?!) they’re a classic, English school dessert.

A chocolate traybake that sets to a hard, crunchy brownie-like cake. There’s lots of texture to a chocolate crunch (also known as a chocolate concrete cake) and they’re super easy and delicious!


Chocolate Concrete (or chocolate crunch cake) has been enjoyed by my family for years, but we set out to veganize it. So this crunchy, delicious chocolate crunch cake is dairy-free, egg-free, and completely vegan. Yum yum!

There’s nothing quite like this recipe, it’s versatile, it’s quick, it’s SUPER easy to make and it is utterly delicious.

Want to take them up a notch?!

Add your favorite chopped up candy bars or candies. Or perhaps try the following (add at step 6):
