Chop 110g of Butter into small chunks (don't melt it at any cost) and toss it into a mixing bowl along with 160g of Caster Sugar. Then, beat them both together until it resembles a thick and even paste
Add 50g of Egg and 4g of Vanilla Extract and whisk together until thoroughly combined
Sift in 160g of Flour, 3g of Baking Powder, 35g of Cocoa Powder, and 3g of Salt. Then stir with a wooden spoon until the liquid has become roughly absorbed, before jumping in with your bare hands and bringing the whole lot together into a singular ball of dough. Don't overwork or knead the dough
Throw in 100g of Granola and 100g of Chocolate Chips, and squash them into the dough until evenly distributed, before bringing the mix back into a ball
Wrap the dough ball in plastic wrap and refrigerate for at least 30 minutes before using (the dough can keep in the fridge for up to a week)
When you’re ready:
Pre-heat the oven to 190°C (375°F, Fan 170°C, Gas Mark 5) and line a baking tray with baking paper
Utilising around 50g of dough per cookie, create discs around 1 cm thick and place them evenly on the baking paper. They'll get bigger, so leave some space in between!.
Bake for exactly 10 minutes, then leave to cool for a minute or two on the tray (they will break if you pick them up straight from the oven), before transferring them to a wire rack to cool completely
Woohoo you have cookies!
