Expert Tips for Best results!
- Use Softened Butter – Make sure your butter is soft but not melted. This helps create that perfect balance between crispy edges and a soft, chewy centre.
- Brown Sugar is the Secret – Using brown sugar instead of white sugar keeps these cookies extra moist and gives them a rich, deep flavour.
- Don’t Skip the Egg Yolk – Since this is a small-batch recipe, just using the yolk (not the whole egg) makes the cookies extra rich and fudgy.
- Freezing for 10 Minutes – If you want thicker, bakery-style cookies, pop the dough balls in the freezer for 10 minutes before baking.
- Let Them Rest – Give your cookies a few minutes on the tray before moving them. This helps them firm up and keeps them from falling apart.
How to make Single Serve Double Chocolate Cookies?






Step 1: Cream Butter and Sugar
Beat the softened butter with brown sugar until light, smooth, and creamy.
Step 2: Add Wet Ingredients
Mix in the egg yolk and vanilla extract until fully incorporated.
Step 3: Mix Dry Ingredients
Sift in the flour, baking soda, salt, and corn starch. Gently mix just until the dough comes together and no dry spots remain.
Step 4: Fold in Chocolate
Fold in the chocolate chips evenly throughout the dough.
Step 5: Shape Dough
Roll the dough into a ball and place it on a lined baking sheet.
Step 6: Bake
Bake in a preheated oven at 175°C (350°F) for 10–12 minutes, until the edges are set and the centre is soft.
Step 7: Cool & Enjoy
Let the cookie cool for 5 minutes before indulging in warm, gooey goodness!
Frequently Asked Questions
What if I don’t have brown sugar? Can I use white sugar instead?
You can, but the cookie won’t be as soft and chewy. Brown sugar adds moisture and a deeper flavour, so if you have it, definitely use it.
Can I use the whole egg instead of just the yolk?
Nope! Using just the yolk makes the cookie rich and fudgy. A whole egg would add too much moisture and change the texture. The middle should still be gooey. You can also chill the dough in the fridge for up to 24 hours before baking.
Do I really need to freeze the dough before baking?
Not necessarily! If you’re short on time, bake it right away. But if you want a thicker, more bakery style cookie, that quick 10 minute freeze makes a difference.
Can I bake this in an air fryer instead of an oven?
Yes! Bake at 160°C (320°F) for about 7 to 9 minutes. Keep an eye on it, since air fryers can bake a little faster than ovens. You can also adjust the baking time slightly if you want to change the sweetness or texture.
