Method
Preparation
- Preheat the oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners or lightly grease the cups.
- In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, salt, and cinnamon. Add both sugars and combine.
- In another bowl, whisk eggs, buttermilk, oil, and vanilla until smooth.
- Pour the wet mix into the dry mix. Stir gently with a spatula — mix just until dry streaks disappear. A few lumps are fine.
- Toss chopped plums with a tablespoon of flour from the dry mix to keep them from sinking. Fold plums and chocolate chips into the batter gently.
- Divide batter evenly among the 12 muffin cups (about 3/4 full) and sprinkle a pinch of sugar on top of each if desired.
Baking
- Bake at 375°F (190°C) for 18–22 minutes until tops spring back lightly and a toothpick inserted comes out with a few moist crumbs.
- Cool muffins in the pan for 5 minutes, then transfer to a rack. Enjoy warm or store for later.
Notes
These muffins are forgiving; swap ingredients, use frozen fruit, or add more chocolate if desired. If using frozen plums, do not thaw fully to avoid a watery batter.
