Rich, moist chocolate sourdough muffins made in one bowl with cocoa, sourdough discard, and chocolate chips. Easy to make, freezer-friendly, and full of flavor.
1½cupsmilk chocolate chips220 grams, or chopped chocolate
coarse sugarfor topping (optional)
Instructions
Preheat your oven to 350°F. Line a standard 12-cup muffin pan with paper liners and lightly spray the liners with nonstick spray.
In a large bowl, whisk together the sugar, sourdough discard, eggs, milk, oil, and vanilla.
Place a sifter over the bowl and add the flour, cocoa powder, baking powder, baking soda, espresso powder (if using), and salt.
Gently fold everything together until well combined. Fold in the chocolate chips. Don’t overmix, just make sure there are no dry pockets of flour.
Divide the batter between the muffin cups. They'll be pretty full, which helps give you that domed top. Sprinkle with coarse sugar if you’d like.
Bake for 20–25 minutes, or until a toothpick inserted in the center comes out clean.
Let the muffins cool in the pan for about 5 minutes, then transfer them to a rack to cool another 10–15 minutes.
Notes
Espresso powder: You can skip it, but even a small pinch boosts the chocolate flavor.Use Dutch-process cocoa: It gives the richest color and taste.Weigh your ingredients: Especially flour, discard, and cocoa, to keep the texture light and moist.Optional rest time: Let the batter sit 20–30 minutes before baking for taller muffins.Longer fermentation: You can refrigerate the batter for 3 to 4 hours before baking. It holds up well and still gives great rise.Freezer-friendly: Cool completely, then store in a zip-top bag for up to 2 months. Thaw at room temp or warm briefly in the microwave.Molten muffin option: This recipe was adapted from our molten chocolate muffins, and you can use the fudge filling technique from that recipe if you want a gooey center.
