In a large mixing bowl stir together flour, baking powder, and spice. Make a well in the center.
Combine eggs, brown sugar, oil, milk, and honey. Add all at once to dry ingredients, stirring just until moistened. Fold in raisins.
Transfer batter to a tightly covered container. Cover and store in the refrigerator for up to 3 days.
To serve, line muffin cups with paper bake cups or grease with shortening. Without stirring batter, fill muffin cups 2/3 full. Bake in a 350 degree F oven about 25 minutes or until a wooden toothpick inserted in center comes out clean. Makes 14 to 16 muffins.
