How to Make the Recipe
Step 1: Preheat and Prep
Get your oven preheated to 375°F (190°C). Line your muffin tin with liners—chocolate batter can be sticky, so this makes cleanup a breeze!
Step 2: Mix the Wet Base
In your favorite large mixing bowl, whisk together the sourdough discard, sugar, oil, milk, vanilla, and egg. Once it’s smooth, whisk in the cocoa powder until there are no lumps left.
Step 3: Whisk the Dry Ingredients
In a separate smaller bowl, sift or whisk together the flour, baking soda, baking powder, and salt. Sifting is great here to make sure everything is extra light.
Step 4: Combine Gently
Fold the dry ingredients into the chocolatey wet mixture. Use a spatula and go slow—you want to stop the moment the flour streaks disappear to keep that “melt-in-your-mouth” texture.
Step 5: The Chocolate Finale
Fold in about 3/4 of your chocolate chips. Save the rest for the very top to make them look absolutely irresistible.
Step 6: Bake to Perfection
Scoop the batter into the muffin cups, filling them about 3/4 full. Press those remaining chips onto the top and bake for 18-22 minutes. A toothpick should come out with just a few moist crumbs.
Step 7: Cool and Enjoy
Let them rest in the pan for 5 minutes, then move them to a wire rack. These are magical when they’re still slightly warm and the chips are melty!
Pro Tips for Making the Recipe
- Quality Cocoa Matters: Since chocolate is the star here, use a high-quality cocoa powder for the richest flavor.
- Don’t Overbake: Chocolate muffins can dry out quickly. Check them a minute or two early—they should be firm to the touch but not hard.
- Coffee Boost: For an even deeper flavor, you can swap the milk for room-temperature brewed coffee!

Notes
How to Serve
These are a total showstopper on their own, but if you want to go all out, serve them with a dollop of whipped cream or a side of fresh raspberries. The tartness of the berries against the rich chocolate is a match made in heaven.
Make Ahead and Storage
Storing Leftovers
Store these in an airtight container at room temperature for 2-3 days. They actually get fudgier by day two!
Freezing
Wrap them tightly and freeze for up to 3 months. Perfect for when those chocolate cravings hit out of nowhere.
Reheating
A quick 10-second zap in the microwave will make the chocolate chips nice and gooey again.
FAQs
- Can I use Dutch-processed cocoa? Yes! Dutch-processed cocoa will give you a darker color and a smoother, mellower chocolate flavor.
- My batter looks very thick, is that normal? Sourdough discard thickness varies. If it’s too thick to scoop, add an extra tablespoon of milk, but remember that a thick batter usually leads to a better muffin dome!
- Can I use chocolate chunks instead of chips? Absolutely! Chunks create bigger “pools” of melted chocolate which is always a win in my book.
- Is this recipe too sweet for breakfast? The sourdough tang keeps the sweetness in check, making these a perfect “treat” breakfast that isn’t cloying.
These Double Chocolate Sourdough Muffins are a true chocolate lover’s dream come true. They are rich, comforting, and the perfect way to show your sourdough starter some love. Happy baking!
