White chocolate macadamia nut cookies are pillowy soft, bakery-style cookies loaded with salty macadamia nuts and white chocolate chips. These cookies are easy to make and full of nutty and sweet flavors.

I think we all know which cookie this white chocolate macadamia nut cookie is a replica of. If you’ve ever been to Costco and gone to their bakery section, then you know that these are the white chocolate macadamia nut cookies I am talking about. For not being a white chocolate fan, I have adored these cookies since I was a kid. The combination of the salty nuts, buttery sweet white chocolate, and pillowy soft cookie just make it so drool-worthy!

Ingredients for White Chocolate Macadamia Nut Cookies
- Butter – unsalted butter softened at room temperature will make it easier to cream together with the sugars and create less clumps.
- Light brown sugar – for a hint of light color, sweetness, and a caramelized flavor.
- Granulated sugar – for sweetness and structure.
- Eggs – to bind it all together!
- Vanilla extract – this will enhance the base of the cookie.
- All-purpose flour – unbleached, all-purpose flour.
- Bread flour – we use bread flour in this because it increases the protein to enable more gluten formation and liquid retention in the dough. This results in a chewier cookie!
- Cornstarch – to balance out the chewiness, the cornstarch will give this cookie an extremely soft texture.
- Baking soda – this will give the cookies a lift and rise.
- Salt – to balance out the sweetness.
- White chocolate chips – I personally like using a higher quality brand for chocolate chips. They’re higher quality for a reason (real ingredients, especially the cocoa butter) and I do think it yields a tastier, richer cookie.
- Macadamia nuts – if you can find them, use salted, dry-roasted macadamia nuts. It works exceptionally well in this and adds extra flavor.

White Chocolate Macadamia Nut Cookies Tips
- Take care to measure your flour correctly. One of the biggest culprits when it comes to cookies (and baked goods in general) is the way you measure your flour. The most accurate will be weighing it on a scale but the second most accurate is to spoon your flour into your measuring cup and level it with a knife.
- Do not omit the cornstarch. Adding in the cornstarch is what gives this cookie a super soft texture so you don’t want to skip this step!
- Use a cookie scoop. Invest in cookie scoops! They make it so every cookie is the same size so it’s even baking. You don’t want one large and one small cookie – one would be underbaked while the other overbaked!

FAQs
As the name implies, it is supposed to be used for bread. We use half all-purpose and half bread flour in this because the bread flour increases chewiness in the cookie. If you use all bread flour, you’ll end up with an extremely dense and cake-like cookie.
You may mix in other toppings like another variety of nuts or dried fruit. Be aware the more you mix in, the harder the dough will be to stay together and your cookie may not spread as well.
Your ingredients were likely too warm (did you melt the butter?) so they spread even more in the oven. If your dough is warm and/or the ingredients are hot, place the dough into the refrigerator to chill for 30 minutes before baking to prevent it from spreading too much.
You can either freeze the dough balls you’ve scooped by placing them on a parchment-lined baking sheet, freeze, then place the frozen dough balls into a freezer-safe container or bag for up to 3 months. Or, my favorite way is to use Souper Cubes cookie trays for even easier freezing and storage. Bake from frozen.
Alternatively, you may freeze the baked cookies after they’ve cooled. Store in a freezer-safe container or bag for up to 3 months. To reheat, allow to come to room temperature then reheat in a toaster oven or oven on low heat until warmed through.
Storage Instructions
Store extra cookies in an airtight container on the countertop with a slice of white bread to keep the cookies soft for an extended period of time. They will be good on the counter at room temperature for up to one week.
Serving Suggestions
- Milk. I remember whenever I had these white chocolate macadamia nut cookies as a kid, I’d always ask for a glass of milk to wash it down. There’s nothing quite like the classic milk and cookies!
- Ice cream. Enjoy white chocolate macadamia nut cookies sandwiched with a scoop of Biscoff Ice Cream to create the most dreamiest flavor combination.
- Add another cookie flavor. The variety pack of cookies that Costco sells includes these white chocolate macadamia nut cookies and chocolate chip cookies. You could totally do the same at home!

Paul doesn’t eat many cookies but when he does they must be white chocolate macadamia nut. These look like a sure winner!
White chocolate macadamia nut cookies are one of my favorite varieties. :) Love the bread flour and cornstarch in these! I know Averie bakes a lot of cookies with bread flour and I’m so eager to give it a try.
I am always up for a cookie! Yum!
Omg! These cookies look amazing!! They’re so puffy! I looove soft cookies! Plus I’m obsessed with all things including white chocolate! It’s my fav! (Is it the bread flour that makes these particular cookies extra fluffy? I’ve never used it in cookies before!) delicious Julie!!
OH the Cosco bakery section. For as much as I love everything that comes out of that corner of paradise, I hate going in too! (I can relate to the claustrophobia/crowd annoyance you shared). White choc macadamia cookies are such a classic that don’t get the spotlight enough. Yours look buttery, soft, and addictive!
These are my dad’s favorite! I’ll have to make them in a few weeks when I see him!
I know exactly what cookies your talking about from Costco. Oh my god. They are SO good. I’ve wanted to recreate them before but macadamia nuts can be pretty pricey, and you’re right…very hard to find. I’ll have to splurge though, because now I’m craving these cookies!
I love white chocolate & macadamia cookies – it’s such a classic combination and it works so well. These cookies look like they are stuffed full of deliciousness!
