What Makes Macadamia Nuts So Special?

Macadamia nuts are known for their rich, buttery texture and delicate sweetness. Compared to other nuts, they’re softer and creamier, which makes them perfect for cookies.

They pair especially well with:

White chocolate
Brown sugar
Vanilla
Sea salt

When baked, macadamia nuts toast slightly, enhancing their flavor and adding the perfect crunch to contrast the soft cookie center.

Ingredients

Wet Ingredients

1 cup (227g) unsalted butter, softened
1 cup (200g) brown sugar
½ cup (100g) granulated sugar
½ cup (120g) sourdough discard (unfed, room temperature)
2 large eggs
1½ teaspoons vanilla extract

Dry Ingredients

2½ cups (315g) all-purpose flour
1 teaspoon baking soda
½ teaspoon baking powder
½ teaspoon salt

Mix-Ins

1½ cups (180g) macadamia nuts, roughly chopped
1 cup white chocolate chips (optional but highly recommended)

Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 180°C (350°F). Line baking trays with parchment paper.

2. Cream the Butter and Sugars

In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together for 2–3 minutes until light and fluffy. This step helps create a soft cookie texture.

3. Add Wet Ingredients

Add eggs one at a time, mixing well after each addition. Stir in the vanilla extract and sourdough discard until fully incorporated.

4. Combine Dry Ingredients

In a separate bowl, whisk together flour, baking soda, baking powder, and salt.

5. Mix Wet and Dry

Gradually add the dry mixture to the wet mixture. Mix until just combined — avoid overmixing.

6. Fold in Macadamia Nuts

Gently fold in chopped macadamia nuts and white chocolate chips.

7. Chill (Optional but Recommended)

For thicker cookies, chill the dough for 30–60 minutes. This prevents spreading and intensifies flavor.

8. Scoop and Bake

Scoop about 2 tablespoons of dough per cookie and place on the prepared trays.

Bake for 10–12 minutes, or until the edges are golden and the centers look slightly underbaked.

9. Cool

Let cookies cool on the tray for 5 minutes before transferring to a wire rack.

Pro Tips for Perfect Cookies

1. Toast the Macadamia Nuts

Lightly toast nuts at 160°C (320°F) for 5–7 minutes before adding them to the dough for deeper flavor.

2. Don’t Overbake

Cookies continue cooking on the tray. Remove when centers look slightly soft.

3. Use Room Temperature Ingredients

This ensures smooth mixing and even baking.

4. Add Flaky Sea Salt

A sprinkle of sea salt before baking enhances sweetness and gives bakery-style results.

Flavor Variations

1. Dark Chocolate Macadamia

Replace white chocolate with dark chocolate chips for a richer flavor.

2. Coconut Macadamia

Add ½ cup shredded coconut for tropical vibes.

3. Brown Butter Version

Brown the butter before mixing for a nutty, caramelized flavor.

4. Gluten-Free Option

Substitute with a 1:1 gluten-free flour blend.

How Sourdough Discard Improves Cookies

If you’re used to making sourdough bread, you know discard often goes to waste. But in cookies, it:

Adds moisture
Improves chewiness
Enhances flavor depth
Slightly reduces sweetness intensity

It doesn’t make cookies sour — it makes them more complex and bakery-quality.

Storage Instructions

Room Temperature

Store in an airtight container for up to 4 days.

Refrigerator

Keeps fresh for up to 7 days.

Freezer

Freeze baked cookies up to 2 months.
Freeze cookie dough balls and bake directly from frozen (add 1–2 minutes to baking time).

Frequently Asked Questions

Can I use active sourdough starter instead of discard?

Yes. Both work fine. Discard simply has a milder rise.

Why did my cookies spread too much?

Butter may have been too soft, or dough wasn’t chilled.

Can I skip white chocolate?

Absolutely. The cookies are delicious with just macadamia nuts.

Can I make them smaller?

Yes — reduce bake time to 8–9 minutes.
