Step 1: Preheat the oven to 350F and and line a muffin tray with parchment paper muffin cups. Add all the ingredients for the muffins into the bowl of your standing mixer and blend well until the batter is smooth.
Step 2: Transfer the batter to the muffin cups, and fill each cup until level with the tray. Bake for 30-35 minutes, until a toothpick inserted inside comes out clean.
Step 3: Drizzle with the melted chocolate and let the muffins cool.
