Ingredients

1 3/4 cups all-purpose flour (see Cook's Note)

2/3 cup sugar

2 tablespoons instant espresso powder

1/2 teaspoon baking powder

1/2 teaspoon kosher salt

4 tablespoons unsalted butter, at room temperature

2 large eggs

1 teaspoon pure vanilla extract

1 1/2 cups salted macadamia nuts, roughly chopped

Directions

  1. Preheat the oven 350 F and line a baking sheet with parchment and set aside.
  2. Pulse the flour, sugar, espresso powder, baking powder and salt in a food processor until combined. Add the butter and pulse until the mixture looks like sand. 
  3. Whisk the eggs, 1 tablespoon water and vanilla together in a large bowl until well mixed then add the flour mixture and stir until a crumbly dough forms. Press together and knead to a moist, uniform dough. Knead in the macadamia nuts.
  4. Divide the dough in half and shape each into an 11-by-2-inch log on the prepared baking sheet, keeping 3-inches between the logs. Brush each log with egg white and sprinkle all over with sugar. Bake for 30 minutes.
  5. Cool the logs for 5 minutes on the baking sheets and then transfer to a cutting board. Cut 1/2-inch thick slices using a sharp serrated knife. Return to the baking sheet and bake again, turning halfway though, until firm and browned, 25 minutes more. Transfer to a wire rack to cool. Store at room temperature in an airtight container for up to 2 weeks.

Cook’s Note

When measuring flour, we spoon it into a dry measuring cup and level off the excess. (Scooping directly from the bag compacts the flour, resulting in dry baked goods.)
