These Dark Chocolate Chunk Cookie Bars are a wonderful treat when you’re in the cookie mood but want to change it up a little. These require no chill time and only your basic cookie ingredients! So easy to make, no shaping or chilling, almost a ‘lazy’ cookie. Hence, why I love a cookie bar so much!
By creating bars rather than individual cookies, you end up with far more of the fudgy centre and there is no need to chill the dough. The only drawback with these is the 30-45min wait after baking before slicing! Although, you could just top with ice cream and dive in with spoons instead. The cornflour is crucial for a solid texture, and the brown sugar gives the sticky, fudgy, rich flavours and texture.
The brown sugar and vanilla are crucial to deep flavours and the gorgeous texture. Everything comes together in just a few steps in one bowl. Being a no-chill cookie recipe means that these are super quick to make. This makes them ideal when you need to prep something with little warning!
Cookie bars are made just the same as cookies, but pressed into a tin rather than baking as individual rounds. Same delicious flavours and textures!

TOP TIPS FOR THE BEST Dark Chocolate Chunk Cookie Bars
- Butter: Fully melted, unsalted butter is best!
- Sugars: The combination of light brown and granulated sugars really contributes to a chewy centre and perfect bake.
- Chocolate: Use any variation of chocolate chunks/chips. I use dark chocolate chunks, but milk/white are great too. Also any sort of chopped chocolate works really well. Ultimately, you can’t go wrong.
- Assembly: When pressing the dough into the pan, just use your hands. The dough is fairly stiff so needs some coaxing to get it into an even layer.
I bake these Dark Chocolate Chunk Cookie Bars I like to use an 8″ square baking dish. For more baking inspiration, head on over to my Instagram.
