Preheat your oven to 350°F (175°C). 2.
In a small bowl, combine the ground macadamia nuts, egg whites, and any optional (salt, vanilla).
Mix until a sticky dough forms. 3.
Divide the mixture evenly into three cavities of an oven-safe silicone candy or mini-muffin mold. 4. Lightly oil your fingertips to prevent sticking, then press the nut mixture firmly into the bottom of each mold. Create a small indentation in the center of each cookie base. 5. Carefully spoon the raspberry puree into the indentations you created. 6.
Bake for 15 minutes, or until the edges are lightly browned and the cookies feel crisp to the touch.
