Why Is My Marshmallow Frosting Runny?
There could be several reasons why your marshmallow frosting is runny. It is possible that you added too much liquid or not enough powdered sugar, or you did not whip the frosting enough to incorporate enough air. Another reason could be that the temperature of the ingredients was too warm, or the marshmallows used in the recipe were old and stale. It is essential to follow the recipe precisely and measure ingredients accurately to ensure the correct consistency of the frosting.
