Preheat your oven to 400 degrees F. Liberally grease a 24-cavity mini muffin tin with cooking spray and set aside.
In a large bowl, whisk together the flour, ½ (HALF) cup of Zulka sugar, baking powder, salt, nutmeg + 1 (ONE) teaspoon of cinnamon to blend. In a medium bowl, combine 1 (ONE) stick of melted butter with the buttermilk, egg and vanilla; whisk together with a fork.
Add the milk mixture to the flour mixture and stir until batter forms; batter will be lumpy. Drop heaping Tablespoonfuls of dough into each mini muffin cavity. Bake for approx. 10 minutes or until muffin tops are puffed and lightly golden, and until a toothpick inserted near the center comes out clean. Cool the donuts in the tin for about 10 minutes.
Meanwhile, place the remaining melted butter in a small bowl, and in a separate bowl, blend together the remaining 1 tsp cinnamon and ½ cup Zulka sugar to combine. Dip each donut into the butter to coat, then transfer to the cinnamon sugar mixture to completely coat. Place the sugared donuts onto a wire rack to set, about 10 minutes. Serve warm or room temperature and store airtight, at room temperature, for several days.
