Instructions

Step 1: Preheat oven to 350°F. In a medium bowl, whisk together 2 cups all-purpose flour, 1 tsp baking powder, 2 tbsp dried Davidson's plum powder, and 1/4 tsp salt.
Step 2: In a large bowl, beat 1/2 cup softened unsalted butter with 3/4 cup granulated sugar until light and fluffy, about 3 minutes. Add 2 large eggs one at a time, then 1 tsp vanilla extract, mixing well.
Step 3: Gradually add the flour mixture into the wet ingredients, mixing until combined. Fold in 1 cup chopped macadamia nuts.
Step 4: Shape the dough into a log about 12 inches long and 3 inches wide on a parchment-lined baking sheet. Bake for 30 minutes until golden and firm.
Step 5: Remove from oven and let cool for 10 minutes. Using a serrated knife, cut the log into 1/2-inch thick slices. Place slices cut side down back on the baking sheet.
Step 6: Bake slices for an additional 10 minutes, then flip and bake 10 more minutes until crisp and toasted. Cool completely before serving.
