A simple, crowd-pleasing sheet cake with tender, moist layers and a creamy, rich buttercream frosting, perfect for graduations and celebrations.
Use room temperature ingredients for best results. Do not overmix batter to keep cake tender. If buttercream is too stiff, add more cream; if too soft, add powdered sugar. Cake can be made a day ahead and stored in fridge; bring to room temperature before serving. For dairy-free or gluten-free options, substitute ingredients as suggested.
