These cookies are a fun riff on the classic chocolate chip cookie. Starting with a similar base recipe, we replace the chocolate chips with fresh (or frozen!) blueberries for a seasonal cookie.

They’re finished with a crumble topping for added extra texture and interest. It’s a simple technique you can apply to all sorts of bakes – I’ve shared some of my favourite ideas below. Be sure to read through to the end for more pro-tips.

Technique of the month: Crumble topping

Crumble – a simple combination of flour, butter and sugar, rubbed together and crisped atop your favourite bakes – is such an easy way to step things up a notch. Take this crumble and use it wherever your heart desires: layered over seasonal fruit and baked for an easy crumble, sprinkled on top of muffins and cakes before baking for a textural crunch, baked off as is and used to garnish yoghurt, ice-cream or smoothies or even to use between cake layers. You can add anything you like to the crumble, too – oats, coconut and spices are all good places to start.
