Chocolate Crunch Recipe pinit

Today, we’re revisiting a beloved classic from many British childhoods: the Chocolate Crunch recipe. This simple yet satisfying treat, also known as chocolate concrete, brings back fond memories of school canteens and delightful breaks with friends. With its firm, crunchy texture and rich chocolate flavour, this dessert is sure to win over hearts and taste buds alike.


Chocolate crunch, or chocolate concrete, made its debut in British school canteens during the 1970s and continued to be a favourite through the 1980s and 1990s. The name “concrete” is quite fitting, as this dessert is known for its hard, crunchy texture. The traditional way to enjoy it is with a side of pink custard, a pairing that not only adds a splash of colour but also a creamy contrast to the crunchy treat.

Serving Suggestions

This chocolate crunch is delightful on its own, but if you’re feeling nostalgic, try serving it with a side of pink custard or even a dollop of vanilla ice cream. For an extra touch of indulgence, drizzle some melted chocolate over the top or sprinkle with colourful sprinkles for a fun, festive look. It also pairs wonderfully with a cup of tea or a cold glass of milk.

Storing Instructions

To keep your chocolate crunch fresh, store it in an airtight container at room temperature. It will stay deliciously crunchy for up to five days. If you prefer a softer texture, you can store it in the refrigerator, but be sure to bring it to room temperature before serving for the best flavour.


We hope this chocolate crunch recipe brings a bit of nostalgic joy to your kitchen. We’d love to hear how it turns out for you! Share your thoughts in the comments below, and don’t forget to subscribe for more delightful recipes and culinary adventures.
