'- 6 tablespoon (90 gram) unsalted butter, softened- 30 gram dark brown sugar- 30 gram sugar- zest of 1 lemon (~ 2 teaspoon)- 1 teaspoon vanilla extract- 15 gram ground macadamia nuts (or almond)- 1/4 teaspoon salt- 3/4 teaspoon baking powder- 120 gram all purpose flour- egg wash (1 egg yolk + 1/2 tablespoon honey)

1. Preheat oven to 320 Fahrenheit (160 Celsius) and line a baking sheet with parchment paper.2. Beat butter, brown sugar, and sugar in a mixing bowl until flight and fluffy. Add lemon zest and vanilla extract, mix again until fully incorporated.3. With a lower speed, mix in ground macadamia nuts, salt, and baking powder. Then, gradually add the all purpose flour in 2-3 batches. Stop beating once soft dough is formed.4. Option 1 (which is what I do): scoop 1 teaspoon of dough and roll into a ball, arrange on baking sheet with 1" spacing around each cookie. Use a fork and press each cookie to create a simple pattern.5. Option 2: transfer cookie dough to a cookie press and press out cookie directly onto prepared baking sheet with 1" spacing around each cookie.6. Brush the top of each cookie with egg wash, then bake in preheated oven for 20-25 minutes, or until golden brown.7. Optional step: brush baked cookies one more time with egg wash, then return to oven (turned off), close the door, and let the cookies sit for 5 minutes, then take them out.8. Make sure cookies are completely cool prior to storing in an air-tight container.
