Preheat oven to 375 degrees F (190 degrees C). Grease 24 mini-mu!in cups or DONUT HOLE PAN
Mix 1/2 cup sugar, 1/4 cup butter, and mace in a large bowl.
Stir in the milk. Stir flour and baking powder together and add to milk mixture. Stir until just combined. Fill the prepared mini muffin cups or DONUT HOLE PAN about half full.
Bake in the preheated oven until the tops are lightly golden, 15 to 20 minutes.
While muffins are baking, place melted butter in a bowl. In a separate bowl, mix together 1/2 cup of sugar with the cinnamon.
Remove muffins from pan while warm, dip each mu!in in the butter and roll in the sugar-cinnamon mixture.
