A light, barely-sweet chiffon cake covered in pastel piped whipped cream dots for the viral Korean bakery look.
Use cold mascarpone and cold cream for a frosting that holds its dot shape — room-temperature dairy will slump. If dots smear together, the cream underneath was too soft; chill and try again. No mascarpone? Whipped cream cheese is a close substitute, just slightly tangier. Cake layers pipe cleanest when baked a day ahead and well chilled.
