The Christmas season officially starts in our house on the first Saturday in December. On that night we make these melt-in-your-mouth desserts, decorate the tree, and hold our Christmas-tree sleepover. We turn of all the lights except for those sparkling on the tree, slip under the covers, and make up fairy tales about our favorite ornaments. If you're short on time, skip the toasting step to make the fluffy white snowballs.
