Instructions
- Step 1: Preheat oven to 350°F and line an 8-inch square baking pan with parchment paper. In a microwave-safe bowl, melt 8 oz chopped dark chocolate and 1/2 cup unsalted butter together in 30-second increments, stirring after each, until smooth.
- Step 2: Whisk in 3/4 cup granulated sugar until well combined. Add 2 large eggs one at a time, whisking vigorously after each to incorporate fully.
- Step 3: Stir in 1 tsp vanilla extract. In a separate bowl, sift together 3/4 cup all-purpose flour, 2 tbsp ground wattleseed, and 1/4 tsp salt.
- Step 4: Fold the dry ingredients gently into the chocolate mixture until just combined. Stir in 1/2 cup chopped macadamia nuts.
- Step 5: Pour batter into the prepared pan and smooth the top with a spatula. Bake for 25-30 minutes until a toothpick inserted in the center comes out with a few moist crumbs.
- Step 6: Cool completely in the pan on a wire rack before cutting into 16 squares to serve.
