Ingredients

Instructions

  1. Step 1: Preheat oven to 350°F and line a baking sheet with parchment paper. In a bowl, whisk together 2 cups all-purpose flour, 1 tsp baking powder, 1 tbsp wattleseed powder, and 1/4 tsp salt until evenly combined.
  2. Step 2: In a separate large bowl, beat 1/2 cup softened unsalted butter with 3/4 cup granulated sugar until fluffy, about 3 minutes. Add 2 large eggs one at a time, mixing well after each addition, then stir in 1 tsp vanilla extract.
  3. Step 3: Gradually fold the dry ingredients into the wet mixture until just combined, then gently fold in 1 cup roughly chopped toasted macadamia nuts.
  4. Step 4: Shape the dough into two logs about 12 inches long and 2 inches wide on the prepared baking sheet. Bake for 25 minutes until golden and firm to touch.
  5. Step 5: Remove from oven and let cool for 10 minutes. Using a serrated knife, slice each log diagonally into 1/2-inch thick slices and arrange cut side down on the sheet.
  6. Step 6: Bake the slices for an additional 10-12 minutes, flipping halfway through, until crisp and lightly toasted. Cool completely before serving.
