Sick Of Cake Frosting Being Ruined By Plastic Wrap? There's A Solution For That (No Toothpicks!) - Tasting Table

"The trick is simple, requiring nothing more than the plastic wrap you've been using that makes a mess - but you'll be using a different technique than flat wrapping or using finicky toothpicks to tent the wrap. It involves creating an air pocket inside the plastic wrap instead of wrapping the cake closely. You create a dome over the cake filled with air, sealed snugly so the cake remains fresh, safe from bacteria that can cause it to spoil or air that makes it go stale."

"To perform this trick, place the cake or cupcakes on a plate or in a wide enough bowl, then wrap the plastic wrap around the bowl or plate with the roll vertical so you have plenty of wrap standing above the cake and its precious frosting. Pull the tall wrap up to a point, then twist and knot the point and let it drop. The trapped air will cause it to fall into a dome so nothing touches your cakes."

"With this nifty dome hack, you'll never fight with plastic wrap again. It's perfect in a pinch, like if your friend is sending you home with leftover cake and they also don't have a carrier or covered cake dish to spare. But there are a few things to keep in mind to get the ultimate result. It works best with larger sizes of plastic wrap rolls. This Fuga City stretch wrap film is 15 inches wide compared to the standard 12-inch rolls. The larger rolls are more common in restaurant kitchens, but they're easy to find online and a good idea to have on hand for all kinds of leftover"

Create an air pocket in plastic wrap to form a dome over a cake or cupcakes, preventing wrap contact with frosting. Place the baked goods on a plate or wide bowl, position the plastic wrap roll vertically, and lift excess wrap above the cake. Twist and knot the lifted point, then release so trapped air forms a dome that keeps frosting untouched. The sealed dome helps maintain freshness and shields the cake from bacteria and stale air. Larger plastic-wrap rolls (about 15 inches) work best and are commonly used in restaurant kitchens and sold online.
