Marble Chocolate Surprise Muffins

Prep Time: 15 minutes | Cook Time: 20 minutes | Serves: 12 muffins

These Marble Chocolate Surprise Muffins are a bakery-style treat that combines the best of both worlds: fluffy vanilla muffin batter swirled with rich chocolate, plus a hidden chocolate bar piece in the center that melts into a gooey surprise. The marbled effect makes them look stunning, while the soft texture and molten middle keep every bite irresistible. The secret? A simple two-tone batter and a chunk of chocolate hidden inside each muffin cup.
