The Secret To Chewy Cookies
If you love biting into a soft cookie and finding it super chewy inside, I've got you sorted! Here's how you can bake deliciously chewy cookies (every single time!):
- Use a combination of white sugar (caster) and brown sugar - but always MORE brown sugar - the extra brown sugar is the key ingredient for soft and chewy cookies. The caster sugar gives the cookies their slightly crispy edges while the brown sugar gives them the most amazing moist and soft inside. You just can't beat it. In this recipe, I use 200g (1 cup) of brown sugar and 100g (½ cup) of caster sugar.
- Use an extra egg yolk - using a whole egg PLUS an extra egg yolk makes these Chewy Chocolate Chip Oat Cookies oh-so soft and chewy! It's the extra egg yolk that makes such a huge difference to the chewiness of cookies.
- Chill the dough - chilling the dough before baking allows the fat to re-solidify. When you bake chilled cookie dough, it will spread more slowly meaning that the outside will cook quicker (and go crispy) while the inside will cook slower (and stay chewy!) Chilling the dough for 30 minutes is essential in this recipe.
- Don't over-bake the cookies - want soft and chewy oat cookies? Then ever so slightly under-bake them! Remove them from the oven as soon as they're lightly golden around the edges (they will still be soft at this stage but will continue to cook and firm up as they cool on the trays). Over-baking the cookies will make them crispier... but they'll lose their soft and chewy filling.

What You Need
Forget about fancy or expensive ingredients, these chewy chocolate chip oat cookies are made from budget-friendly pantry and fridge staples:
Note: Scroll to the recipe card at the bottom for the ingredients, quantities and full detailed method.
- Unsalted butter - I like to use unsalted butter and then add a pinch of salt to the mixture. This allows you to control the amount of salt in the cookies and taste to your liking.
- Brown sugar - you can use either light (regular) or dark brown sugar for this recipe. Dark brown sugar will result in extra chewiness and a more caramelised flavour. I generally use regular light brown sugar.
- Caster sugar - also known as superfine sugar. This fine white sugar easily dissolves when creamed with the butter (making it perfect for cookies!).
- Vanilla extract - or vanilla essence or vanilla paste
- Egg + an extra yolk - the extra yolk is KEY to making those super soft and chewy cookies. Have your eggs at room temperature when you start.
- Plain flour - also referred to as all purpose flour.
- Bi-carbonate of soda and baking powder - also known as baking soda and baking powder, these two ingredients act as the rising agents in these soft and chewy oatmeal chocolate chip cookies.
- Rolled oats - old fashioned rolled oats give these cookies a delicious nuttiness and texture.
- Chocolate chips - you can use milk, dark or white chocolate chips for this recipe. Alternatively, you could substitute the chocolate chips for Smarties or M&Ms or even add in raisins or nuts.
- Sea Salt - adding a pinch of sea salt to the still-warm cookies straight out of the oven brings out the flavour of the cookies while also neutralising the sweetness of the sugar. This is optional but HIGHLY recommended!
Step By Step Instructions
It could not be easier to make a batch of oat and chocolate chip cookies. With just 15 minutes prep time and a stand mixer (or hand-held beaters or a Thermomix), you'll have a batch of warm cookies ready to eat in no time!
Note: Scroll to the recipe card at the bottom for the ingredients, quantities and full detailed method.
Step 1 - Cream The Butter & Sugars
Using handheld beaters, a stand mixer or a Thermomix, beat the butter, brown sugar and caster sugar until smooth and creamy.
Step 2 - Add The Wet Ingredients
One at a time, beat through the egg, the extra egg yolk and vanilla extract until well combined.
Step 3 - Add The Dry Ingredients
Sift through the plain flour, bi-carbonate of soda and baking powder. Add the rolled oats and chocolate chips then fold through using a large spoon or spatula.
Step 4 - Chill The Dough
Note: This is a REQUIRED step.
Chill the dough in the fridge for 30 minutes.
Step 5 - Roll & Bake
Roll the chilled dough into heaped tablespoon-sized balls.
Place onto the prepared trays and bake for 12-15 minutes or until ever so slightly golden on the edges.
Allow to cool on the baking trays for 10 minutes before transferring to a wire rack to cool completely.
Recipe Tips & FAQs
I really do HIGHLY recommend using old fashioned rolled oats as they give the cookies a nutty and chewy texture. Quick oats are much finer and don't give the oat cookies the same taste or texture.
It absolutely is! Chilling the dough before baking allows the fat to re-solidify. When you bake chilled cookie dough, it will spread more slowly meaning that the outside will cook quicker (giving you slightly crunchy edges) while the inside will cook slower (and stay soft and chewy!).
Even after chilling, these chewy chocolate chip oat cookies still spread a LOT so it's important to leave a large (5-7cm) gap between them on the baking trays.
You can add, or substitute the chocolate chips with, anything you like in this basic oatmeal cookie recipe! A few favourite add-ins of mine include raisins, nuts, cinnamon or M&Ms.
Storing & Freezing

Karen
When cooking a batch from frozen, what are the thawing/cooking instructions?
Can they be placed in the oven while frozen?
Lucy
Hi Karen, you'll just need to place the dough in either the fridge or on the bench to defrost. One defrosted, roll into balls and bake!
Naomi Riley
My family’s new favourite cookie recipe. I always halve the batch and add extra oats with no chocolate chips to one half so that both my girls have their preferred cookie type. These cookies work perfectly every single time and are so easy to make, we make a batch every week now.
Lucy
These are a favourite in our house too! xx
Ain Norman
What a great recipe! My son loves them! Thanks for sharing ❤️
Lucy
That's so great to hear! Thank you so much!
Dianne
My kids (and husband) love, love, love these. I chilled the cookies but they didn't spread out at all.... didn’t affect the taste though!
I did halve the sugar and used milk chocolate chips!
Also made your almond and coconut cake yesterday... we love it.
Thankyou so much for a terrific website and recipes
Lucy
Hi Dianne, oh you have absolutely made my day! I really appreciate your lovely feedback. xx
