Ingredients

For the base

• 2 sticks (1 cup) unsalted butter, softened
• 3/4 cup packed light brown sugar
• 1/2 cup granulated sugar
• 2 large eggs, room temperature
• 2 teaspoons vanilla extract

Dry ingredients

• 2 1/2 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon fine sea salt

Add-ins

• 1 1/2 cups white chocolate chips or chopped white chocolate
• 1 cup chopped macadamia nuts, lightly toasted (optional: reserve a few whole halves for topping)

Notes: If your butter is cold, microwave in 5-second bursts until soft but not melted. Toast macadamias on a sheet at 350°F for 6–8 minutes until fragrant.

How to Make White Chocolate Macadamia Cookie Bars

1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang to lift the bars out later. (This makes cleanup and slicing easier.)
2. In a large bowl, cream the softened butter with brown and granulated sugars until smooth and slightly fluffy, about 2–3 minutes. This traps air for a light texture.
3. Beat in the eggs one at a time, then stir in the vanilla until fully mixed. The batter will smell rich and vanilla-forward.
4. In a separate bowl, whisk together the flour, baking soda, and salt. This ensures even rising and no clumps of baking soda.
5. Gradually add the dry mix to the wet mix, stirring until just combined. Don’t overmix — that keeps the bars tender.
6. Fold in the white chocolate chips and toasted macadamia pieces with a spatula. Save a handful to sprinkle on top for a prettier finish.
7. Press the dough evenly into the prepared pan using your fingers or the back of a spatula. Press firmly so the bars bake evenly.
8. Scatter reserved chips and nuts over the top, gently pressing them into the dough.
9. Bake for 22–28 minutes, or until the edges are golden and the center looks set but still soft. A toothpick in the center should come out with a few moist crumbs. The kitchen will smell warm and nutty.
10. Cool completely in the pan on a wire rack — about 1 to 1.5 hours — before lifting out and slicing into bars. Cooling helps the bars hold together when cut.

How to Serve White Chocolate Macadamia Cookie Bars

• Cut into squares and serve warm with a scoop of vanilla ice cream for a cozy dessert.
• Arrange on a platter and sprinkle with a little flaky sea salt for a grown-up sweet-salty contrast.
• Pack a few bars in lunchboxes with a piece of fruit for a sweet treat.

How to Store White Chocolate Macadamia Cookie Bars

• At room temperature: place cooled bars in an airtight container for up to 3 days. Keep a piece of parchment between layers to stop sticking.
• In the fridge: store airtight up to 7 days. Bring to room temperature or warm for 10–15 seconds in the microwave.
• In the freezer: wrap bars tightly in plastic and foil, or freeze in a sealed container for up to 3 months. Thaw overnight in the fridge or warm slices in a low oven (300°F) for 8–10 minutes.

Tips to Make White Chocolate Macadamia Cookie Bars

• Use room-temperature eggs — they blend better and give a smoother batter.
• Don’t overbake; pull the bars when the center still feels slightly soft. They firm up as they cool.
• Toast the macadamias for extra depth of flavor — they’ll smell nutty and golden.
• Press the dough evenly into the pan to avoid thin, overbaked edges.

Variation

• Gluten-free: swap in a 1:1 gluten-free baking flour blend and add 1/4 teaspoon xanthan gum if your blend needs it.
• Vegan: use 1/2 cup coconut oil plus 1/2 cup vegan butter, and replace eggs with two flax eggs (2 tbsp ground flax + 6 tbsp water). Use dairy-free white chocolate chips.

FAQs

Can I use salted butter instead of unsalted?

Yes. If you use salted butter, reduce added salt to a pinch (about 1/8 teaspoon) to avoid an overly salty result.

Can I make the dough ahead of time?

Yes. Chill the dough in the pan, covered, for up to 24 hours before baking. If chilled, add an extra 2–3 minutes to baking time.

How do I stop the bars from crumbling when I cut them?

Cool completely before slicing and use a sharp knife wiped clean between cuts. Chilling in the fridge for 20–30 minutes helps very soft bars slice cleanly.

Can I swap macadamia nuts for another nut?

Absolutely. Pecans or chopped almonds work well and add a different texture and flavor.
