Roasted White Chocolate and Macadamia Nut Cookies

If you've ever thought white chocolate was a bit sweet and one-dimensional, you haven't had it roasted. Roasting white chocolate in the oven caramelises the milk solids and transforms it into something with genuine depth, nutty, complex, and with that beautiful golden colour throughout the cookie. Paired with roasted macadamia nuts, it is absolutely spectacular. These are thick, chewy, plump cookies with proper bakery-style results. Once you've made them this way, the standard version won't cut it anymore. Let's make them!

Recipe Details

• Prep Time: 20 minutes
• Cook Time: 30 minutes (including roasting the chocolate and nuts)
• Total Time: 50 minutes
• Makes: 12 large, plump cookies
• Difficulty: Easy

The secret to these cookies is patience at two points: roasting the chocolate slowly until it's properly golden, and creaming the butter and sugar for a full 8 to 10 minutes. Both steps might feel like overkill, but they're what give you that extraordinary texture and flavour. Don't rush either one.

Why You'll Love This Recipe

• The roasted white chocolate is genuinely transformative: it goes from sweet and flat to nutty and complex. It's one of those techniques that seems fiddly but is actually hands-off and completely worth it.
• Thick and chewy, not thin and crispy: the double sugar and low oven temperature give you a proper bakery-style cookie, not a flat disc.
• They keep beautifully: these cookies stay soft and chewy for days in an airtight container, which means they're perfect for making ahead.
• Impressive without being difficult: the ingredient list is simple. The roasting step is what makes them look and taste like something from a bakery.
• Freezer-friendly dough: roll into balls and freeze unbaked. Bake straight from frozen whenever you need them.

Ingredients

• 150g unsalted butter, softened to room temperature
• 175g (1 cup) brown sugar
• 165g (3/4 cup) white sugar
• 2 teaspoons vanilla extract
• 1 egg
• 225g (1 1/2 cups) plain flour, sifted
• 1/2 teaspoon baking powder, sifted
• 1/2 teaspoon fine salt
• 250g white chocolate, chopped (or use white chocolate drops for easier handling)
• 150g macadamia nuts, roasted and roughly chopped

Instructions

1. Preheat and prep: Preheat your oven to 170°C (325°F). Line two baking trays with baking paper.
2. Roast the white chocolate: Spread the chopped white chocolate (or drops) on one of the lined trays in a single layer. Place in the oven and check at 10 to 15 minutes. It will start to look a little mottled and caramelised at the edges. Keep going until it's an even golden colour, this can take up to 30 minutes. Stir every 10 minutes or so to help it colour evenly. Once golden, remove from the oven and set aside to cool completely. It may seize and look lumpy as it cools, that's fine, just re-chop it before adding to the dough.
3. Roast the macadamia nuts: On a separate tray, spread the macadamia nuts and roast at the same temperature for around 5 minutes. Watch them carefully, macadamias have a high oil content and catch quickly. You want a light golden colour. Remove and leave to cool completely, then roughly chop.
4. Cream the butter and sugars: In a stand mixer with a paddle attachment (or using a hand mixer), beat the softened butter, brown sugar, white sugar, and vanilla together for 8 to 10 minutes until the mixture is pale, light, and creamy. This is the most important step for texture, don't cut it short.
5. Add the egg: Scrape down the sides of the bowl, add the egg, and beat well until fully combined and the mixture looks smooth.
6. Add the dry ingredients: In a separate bowl, sift together the flour, baking powder, and salt. Add the dry ingredients to the butter mixture and mix on low speed until a soft dough just comes together.
7. Fold in the chocolate and nuts: Add the cooled roasted white chocolate and macadamia nuts to the dough and fold through with a spatula or wooden spoon until evenly distributed.
8. Shape and bake: Roll heaped tablespoons of dough into balls (about 2 tablespoons each) and place on the prepared trays, leaving plenty of room for spreading. Gently press each one down slightly. Bake for 15 to 17 minutes until the edges are set and golden, but the centres still look a little underdone. That's exactly right.
9. Cool on the tray: Leave the cookies on the tray for at least 10 minutes before moving, they'll be too soft to handle straight out of the oven, and they continue to set as they cool. The centres will firm up into that perfectly chewy texture.

Chef's Tips

Roast until properly golden: A lot of recipes say roasted white chocolate but pull it out as soon as it looks a bit blond. You want genuinely golden. The flavour transformation only happens once the milk solids have properly caramelised. Be patient and keep going.

Your butter must be properly soft: If the butter is too cold it won't cream properly and you'll end up with a dense, greasy cookie. The butter should leave an indent when you press it. If yours came straight from the fridge, cube it and leave it at room temperature for an hour.

Don't overbake: These cookies will look underdone in the centre when you pull them out. That's intentional. They continue cooking on the hot tray as they cool. If they look perfectly set in the oven, they'll be overdone once cooled.

Cool the chocolate and nuts completely: Adding warm chocolate or nuts to the dough will melt the butter and affect the texture. Give them time.

Freeze the dough balls: Once shaped, freeze unbaked dough balls on a tray until solid, then transfer to a freezer bag. Bake straight from frozen at 170°C, just add a few extra minutes to the bake time. Fresh warm cookies whenever you want them, with almost no effort.

Substitutions & Variations

• No macadamia nuts? Blanched almonds, cashews, or pecans all work well. Just roast them the same way.
• No white chocolate? Milk chocolate and macadamia is also an excellent combination. Skip the roasting step and just use good quality milk chocolate chopped into chunks.
• Want smaller cookies? Use 1 tablespoon of dough per cookie instead of 2. Reduce the bake time to 12 to 14 minutes.
• Add a sprinkle of sea salt: A pinch of flaky sea salt on top of each cookie right before baking elevates the whole thing. Highly recommended.
• Double chocolate version: Replace 30g of the flour with good quality cocoa powder for a chocolate dough with roasted white chocolate chunks throughout.

Storage

Room temperature: Store in an airtight container for up to 5 days. They stay soft and chewy throughout.

Freeze baked cookies: Once fully cooled, layer between sheets of baking paper in a freezer-safe container. Freeze for up to 3 months. Thaw at room temperature for about 30 minutes, or warm briefly in the oven.

Freeze unbaked dough: Shape into balls, freeze on a tray until solid, then bag up and freeze for up to 3 months. Bake straight from frozen, adding a couple of extra minutes to the bake time.

Frequently Asked Questions

What does roasting white chocolate do?
It caramelises the milk solids in the chocolate, turning it from sweet and one-dimensional into something nutty, complex, and almost toffee-like. It's the same Maillard reaction that browns bread crust and caramelises onions, applied to chocolate. The result is a completely different ingredient.

Do you have to roast the macadamia nuts?
You don't have to, but you really should. Raw macadamias are buttery and mild. Roasted macadamias are rich, deeply nutty, and have much more flavour. The 5 minutes it takes is absolutely worth it.

Why do my cookies go flat?
Usually one of three things: the butter was too soft or melted (should be soft but hold its shape), the dough was too warm when it went into the oven, or the oven wasn't properly preheated. Pop the shaped dough in the fridge for 15 minutes before baking if your kitchen is warm.

Can I make the dough ahead of time?
Yes. Make the dough, shape into balls, and refrigerate for up to 48 hours or freeze for up to 3 months. Bake straight from the fridge or freezer, no need to bring to room temperature.

How do I keep cookies thick and not flat?
The double sugar method (brown and white together) creates a chewier, thicker cookie. Baking at a lower temperature (170°C instead of 180°C or higher) also slows the spread, which means the cookies puff up rather than spreading out thin. Don't skip the creaming time either, the air you beat in at that stage gives the cookies their lift.

Can I use white chocolate chips instead of chopped chocolate?
Yes, that's what the recipe suggests for easier handling. Chips are easier to roast and don't need re-chopping after cooling. Either works.
