Place cake on a cooling rack with a pan beneath it to catch any extra glaze drippings. Place a spoonful of glaze on the top of the cake, near an edge. Slightly spread glaze using the spoon and gently press a small amount of the glaze over the edge of the cake to create a drip. Move spoon over slightly and repeat to create additional drips. When the entire cake is covered in drips, cover center of top of cake with remaining glaze. Use additional garnishes as desired. Refrigerate finished cake to let the glaze set prior to serving, approximately 30 minutes.
