Larger drop flower tips are frequently used to make the classic rose swirl on cupcakes. These can be used to make petals or to construct flowers such as roses. The form of the nozzle's end might vary, as seen in the photo. Some people like to keep them flat, while others curve their ends slightly. You can use any size you want, but for best results use a tip with a diameter of about 1/4 inch (6 mm). Cupcake liners help maintain the shape of the cup when baking and also help keep cakes from sticking to the pan. You will need 12-14 standard-sized muffin cups for one batch of cupcakes. If you don't have liners, regular cups can be used instead but they won't look as nice. Muffins tend to be very leavened so you don't need to worry about underbaking them. For a more cake-like texture, undercook them a little bit. They will continue to cook once removed from the oven. You can decorate your cupcakes at any time after they come out of the oven. Just be sure to give them enough time to cool down completely before eating.
