Dark Chocolate Muffins with Molten Centers

Rich, fudgy muffins made with 70% cocoa chocolate and butter, lightened with whipped eggs and ground almonds. A square of dark chocolate pushed into each center creates a molten surprise.

Tips
Use a double boiler or heatproof bowl to prevent chocolate from seizing during melting.
Whisk eggs thoroughly to incorporate air, which helps the muffins rise.
Insert the chocolate square into warm batter so it sinks slightly and creates a pocket.
Do not overbake; the muffins should be set but still moist inside.
Good to Know
Airtight container at room temperature for up to 2 days; refrigerate for longer storage.
Prepare batter up to 2 hours ahead; refrigerate. Fill cases and bake just before serving for optimal molten center.
Warm, ideally within 10 minutes of baking to enjoy the molten chocolate center.
Common Mistakes
Do not stir the folded batter excessively to avoid deflating whipped eggs and reducing rise.
Do not skip sifting sugar and flour to avoid lumps in the final texture.
Do not insert chocolate square too late; it should be surrounded by batter to create a pocket.
