If you’re looking for an easy homemade treat that everyone will love, these Chocolate Crumble Squares are just the recipe. They’re rich, chocolatey, crumbly, and incredibly simple to make using ingredients you probably already have in your store cupboard.
They’re perfect for summer snacking, packing into picnic baskets, enjoying with a cup of coffee, or adding to a lunchbox for a special treat. Best of all, they come together with very little effort, making them ideal when you need something delicious in a hurry.
One of my favourite things about this recipe is how adaptable it is. If you’re making these for a school lunchbox or need a nut-free option, simply swap the peanut butter for Biscoff spread. You still get that deliciously creamy layer, but without the nuts, making them suitable for more lunchbox policies.
I recently made a batch for my daughter’s movie night with her friends, and they disappeared in no time! Safe to say they were a huge hit. There’s something about the combination of buttery crumble and rich chocolate that keeps everyone coming back for another square.
These are also a brilliant recipe to make ahead. Once cooled, they store well in an airtight container, making them perfect for grabbing throughout the week whenever you fancy a sweet treat.
