This marshmallow buttercream frosting combines rich, smooth butter with sweet, fluffy marshmallow cream for a frosting that’s light, stable, and easy to pipe. Perfect for cupcakes, cakes, and all your special occasion desserts.
For brighter white frosting, use clear vanilla extract.
To make less sweet, add an extra pinch of salt or a dash of lemon juice.
This frosting holds up well at room temperature for up to 8 hours (in moderate climate).
