Here we go. Another cookie jar favorite from my kitchen to yours.

My mind was completely blown after biting into one of these cookies warm from the oven. The molasses and cinnamon-spiced oatmeal cookie base paired with buttery macadamia nuts and sweet white chocolate is out of this world. Like regular white chocolate macadamia nut cookies, but with extra texture. If you’re looking for a new cookie recipe to try, this is it.

I have a few helpful notes about your white chocolate macadamia nut oatmeal cookies (um, try saying that 3 times fast) – and I encourage you to read them before beginning.

The oatmeal cookie dough recipe calls for more brown sugar than white sugar. In fact, most of my cookie recipes do. I prefer to use more brown sugar than white sugar because brown sugar holds more moisture than white sugar – and thus produces a softer, moister baked good. I like to use dark brown sugar since it has a slightly higher amount of molasses. However, if you’re in a pinch and only have light brown sugar – that’s ok!

I love adding a touch of dark molasses to my oatmeal cookie dough. It’s a little something I picked up from one of my cookbook cookie recipes (recipe on page 109!). 1 Tablespoon doesn’t sound like much. And you’re right! It’s not that much. But it’s just enough to give a subtle amount of extra molasses flavor. However, don’t go buy a bottle just for this recipe. They’re fine without it.

There is always the question of which type of oats to use in cookie recipes. I use old-fashioned whole oats in this recipe, as opposed to quick oats. Quick oats, which are more powdery than whole oats, may dry out your cookies. You could certainly try using them, but I prefer whole oats. They give more texture: hearty, chewy, thick.

Today’s oatmeal cookie dough is slightly sticky, so it’s best to chill it before baking. You’ll want these cookies to spread, but not overspread into flat discs on your baking sheet. So, chill the dough for about 30 minutes. (I chilled today’s dough for 25 minutes.)

I use a cookie scoop for oatmeal cookies; it grabs onto the textured cookie dough better than my hands can. Here’s the cookie scoop I use– I own it in sizes medium and large, and I used size medium for these cookies. Scoop/roll 1.5 Tablespoons of dough per cookie.

Press a few extra white chocolate chips and/or macadamia nut chunks directly into the tops of the cookie dough balls. This guarantees you’ll have a few pretty chunks on top of your baked cookies. Like so:

There are no secret ingredients here, no rocket science knowledge required – just a simple, straightforward soft-baked oatmeal cookie recipe with the crunch of macadamia nuts and the creaminess of white chocolate. Simple perfection!

PS: Here is my white chocolate macadamia nut cookie recipe without oats.

Description

Soft-baked, ultra chewy, and simple oatmeal cookies loaded with white chocolate and macadamia nuts. Only 30 minutes to chill, you’ll have oatmeal cookies in no time!


Ingredients

Scale
  • 1/2 cup (115g) unsalted butter, softened to room temperature
  • 3/4 cup (150g) packed light or dark brown sugar 
  • 1/4 cup  (50g) granulated sugar
  • 1 large egg, at room temperature
  • 2 teaspoons pure vanilla extract
  • 1 Tablespoon (20g) dark molasses
  • 1 and 2/3 cups (140g) old-fashioned rolled oats
  • 1 cup (125g) all-purpose flour (spoon & leveled)
  • 1/2 teaspoon ground cinnamon
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 3/4 cup white chocolate chips
  • 3/4 cup chopped macadamia nuts

Instructions

  1. Using a hand mixer or a stand mixer fitted with paddle attachment, cream the softened butter and both sugars together on medium speed until smooth. Add the egg and mix on high until combined, about 1 minute. Scrape down the sides and bottom of the bowl as needed. Add the vanilla and molasses and mix on high until combined. Set aside.
  2. In a separate bowl, toss the oats, flour, cinnamon, baking soda, and salt together. Add to the wet ingredients and mix on low until combined. Fold in the white chocolate chips and macadamia nuts. Dough will be thick. Chill the dough for 25-30 minutes in the refrigerator.
  3. Preheat oven to 325°F (163°C). Line two large baking sheets with parchment paper or silicone baking mats.
  4. Roll balls of dough (about 1.5 tablespoons of dough per cookie) and place 2 inches apart on the baking sheets. I pressed a few extra white chocolate chips/nuts into the tops of the cookies for looks. Bake for 10-11 minutes until very lightly browned on the sides. The centers will look very soft. Remove from the oven and let cool on baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Notes

  1. Make Ahead & Freezing Instructions: Cookies stay fresh covered at room temperature for up to 1 week. You can make the cookie dough and chill it in the refrigerator for up to 4 days. Allow to come to room temperature and continue with step 3. Baked cookies freeze well – up to three months. Unbaked cookie dough balls freeze well – up to three months. Bake frozen cookie dough balls for an extra minute, no need to thaw. Read my tips and tricks on how to freeze cookie dough.

Reader Questions and Reviews

  1. Sally,
    I made these yesterday for Easter and they were a HUGE hit!! They were sooo delicious and turned out perfect!
    Thank you!!

  2. How could you incorporate dried pineapple or dried apricots into this recipe? I have that needs to be used up!!

    1. That sounds delicious! Keep the total amount of add-ins to 1 and 1/2 cups – so keeping under that amount, add however much of any add-ins you’d like. Enjoy!

  3. Have you ever tried to make bars with this recipe? If so, how’d it turn out and what do you recommend?

    1. I have not– though I make oatmeal cookie bars with a similar recipe quite often. Use an 8-inch or 9-inch square baking pan. About 25-27 minutes bake time. Same oven temp.

  4. is there a reason you didn’t use cornstarch in these?  you’ve said this ingredient is key to keeping cookies soft.  sending these cookies to my bro-in-law in arkansas for a pick-me-up treat and will have to mail them.  hoping to make them stay as fresh as possible! thanks for all the great recipes!!!

    1. They’re super soft without it! I usually only use cornstarch in chocolate chip cookies. (without oats)

  5. Hi Sally! I always use your cookie recipes and every time I do they are a big hit! I want to make these cookies for an event coming up but I can’t find white chocolate chips anywhere. I live in Colombia now so little things like this can be hard to find. Could I use chocolate chips instead of white or would it be too sweet?

  6. Made these yesterday for a visiting relative – my excuse to go crazy cookie baking lady. They were nice but for some reason the cinnamon didn’t work for me. I’m not sure why, I’ve made similar cookies before so I suspect my cinnamon was sub-par, maybe too old or not kept in an airtight container. I also baked them a tad longer than the recipe says; us Aussies like our cookies a bit harder.
    I’ll give them another go with fresher spices.

  7. I just made these… I reduced the brown sugar & the white chocolate chips to to a little less than the 3/4 as I don’t like it very sweet. It was still a bit too sweet for me..might reduce the white chocolate chips to 1/2 cup & increase the nuts to 1 cup. I also had to cook it for 14 mins. They are delicious and will be making these again..thanks Sally My daughter is obsessed with all your goodies so I thought I would give it a try..sure glad I did

  8. Let’s just say I rarely comment on a recipe, especially a cookie recipe, but these are amazing. I bake cookies all the time, like 6 times a week, just decided to try something new and I’m thrilled I did. On top of that I rarely eat my own cookies, but these are irresistible. Thanks!

    1. Hi Sienna! 3/4 cup chopped macadamia nuts would weigh about 90g and 3/4 cup white chocolate chips would weigh about 75g.

      1. Do you think that I can add more macadamia nuts, white chocolate chips and if so how much more in grams?
        Also, can I add dried cranberries and how much in grams?
        Sorry for all the questions, lol. Have a nice day!
