For best results, use good-quality dark chocolate (around 60–70% cocoa) for both the truffle centers and ganache, as it will greatly impact flavor and texture; ensure all refrigerated ingredients are at room temperature before mixing to avoid a dense crumb, and do not overmix the batter once the dry ingredients are added to keep the cupcakes tender. If the truffle mixture becomes too firm to scoop, let it sit at room temperature for a few minutes until pliable, and if the ganache is too thin, cool it longer, or if too thick, briefly warm it over a water bath. Store cupcakes in an airtight container at cool room temperature for up to 2 days or refrigerate for longer, bringing them back to room temperature before serving so the truffle centers are soft and silky.
