Ingredients
Method
Step 1: Melt the Butter
Dice the butter and place it into a large microwave-safe bowl. Heat in short bursts (about 30–60 seconds total) until fully melted. Allow it to cool slightly before moving to the next step.
Step 2: Mix the Sugars
Add the caster sugar and brown sugar to the melted butter. Stir thoroughly with a spatula until smooth and glossy.
Step 3: Add Eggs & Vanilla
Crack in the whole egg, then add the extra yolk and vanilla extract. Mix until fully incorporated and silky.
Step 4: Form the Dough
Tip in the self-raising flour and salt. Fold everything together gently until a thick cookie dough forms. Avoid overmixing.
Step 5: Add Chocolate
Roughly chop your chocolate into small chunks and fold them evenly through the dough.
Step 6: Chill for Flavor
Cover the bowl and refrigerate for at least 5 hours, ideally overnight.
Tip: Longer chilling = deeper flavor and better texture.
Step 7: Prepare the Oven
Preheat to 180°C (fan) or 200°C (conventional). Line baking trays with parchment paper.
Step 8: Soften the Dough
Remove the dough from the fridge and let it sit at room temperature for about 30 minutes so it’s easier to shape.
Step 9: Shape the Cookies
Scoop generous tablespoons of dough and roll into balls. You should get around 12–14 cookies.
Step 10: Arrange & Bake
Place 3–5 balls per tray, spacing them apart. Bake for 10 minutes. The edges should look lightly golden while the centers remain soft and pale.
Important: Slight underbaking is the secret to soft, gooey centers. The cookies will continue cooking as they cool.
