White chocolate macadamia nut cookies with soft and chewy centers and crisp edges.
In a very large, microwave-safe bowl, melt the butter. Once melted, stick it in the fridge for 5 minutes. It's important the butter isn't hot when you add in the sugars or it will melt the sugar and make the cookies greasy.
Once butter is cooled to room temperature, stir in the light brown sugar and white sugar. Stir until smooth. Stir in the egg, vanilla extract, almond extract, coconut extract, and agave nectar. Stir until smooth.
Add in the cornstarch, salt, baking soda and baking powder. Again, stir until smooth. Add in the *correctly measured flour and mix until JUST combined. Don't overmix.
Gently stir in the white chocolate chips and macadamia nuts until combined.
Cover the bowl tightly and chill for 1 hour.
Preheat the oven to 350 degrees F. Line a pan with parchment paper or use a nonstick liner.
Roll balls of dough into tall cylindrical balls (see picture above for shape and size). Place 6-8 cookie balls on a sheet pan to give the cookies plenty of room to spread. Dough balls should be about 1.7 ounces.
Bake for 8-12 minutes erring on the side of under-baking which keeps them soft and chewy (We like ours right at 9 minutes)! Remember the cookies will bake a little more out of the oven, so take them out as soon as the edges start to lightly brown!
Remove from the oven and press a few additional chocolate chips or macadamia nuts in the top if desired (makes them look pretty). Allow to cool on the baking tray for 5 minutes before transferring them to a cooling rack.
Cook time refers to chilling time.
*When measuring the flour, do not press the measuring cup into the bag of flour as that packs in a ton more flour. Spoon the flour into the cup and then level. The flour should completely fill up the cup measurer without being packed in. Measuring the flour correctly is going to give you the most success with this recipe! If the cookies are spreading too much you likely didn't add enough flour; if the cookies are cakey and too thick, you have too much flour.
