Light, airy vanilla bean cupcakes topped with homemade marshmallow fondant shaped into cute ghosts, featuring a tangy sour cream filling for a perfect Halloween treat.
Ensure all ingredients for the batter are at room temperature for proper emulsion. Do not overmix the batter to keep cupcakes tender. Let cupcakes cool completely before adding fondant to prevent melting. If fondant is too sticky, add more powdered sugar; if too dry, add a tiny bit of water. Store at room temperature; do not refrigerate.
