Double chocolate muffins made with sourdough discard. These have bakery style domes, a moist texture and a very chocolatey flavor.
This sourdough double chocolate muffin recipe is now a little over a year old; I started making them last summer – inspired by the success of my sourdough brownies – and my daughter liked them so much she asked to have them for her birthday party last year (I did feel a tad disappointed I couldn’t make cute cupcakes but also honored she liked these that much).
What’s great about this recipe is you have some room for preferences: use any chocolate chip you like, or don’t and add nuts. Use an oil if you are avoiding butter, and if you have a dairy free yogurt you can thin it out with water and make the muffins completely dairy free.
This is a sourdough adaptation of a very old recipe on the site: double chocolate chip olive oil muffins. Because we have that added moisture from the discard, we can use butter in the batter rather than oil and the muffins will stay moist.
Discard also keeps these from being too sweet and honestly, it’s just a great way to use up leftover starter when you tend to bake bread as often as I do =)
Eggs: large eggs, it is best if they are at room temperature.
Sugar: brown sugar, light or dark. If you only have fine granulated that works too.
Butter: unsalted butter, we’ll melt it. You can substitute this with 100g or ½ cup of avocado oil if you prefer. If you like you can brown the butter, it shouldn’t impact the muffins too much (they are quite moist!).
Salt: fine sea salt. If using table salt, halve the amount.
Vanilla: pure vanilla extract. It’s ok to leave this out if you don’t have it.
Cocoa: dutch process cocoa. This has been alkalized and balances with the recipe’s chemistry. I have not tested the recipe with natural cocoa or black cocoa but I would expect some differences in rise and texture.
Discard: leftover sourdough starter. Up to a week old should be ok.
Leavening: baking soda.
Buttermilk/kefir: as long as they are plain, both of these work. The buttermilk can be low fat or full fat. If you have neither, you can thin out some plain greek yogurt with water to use instead.
Flour: all purpose flour, of a medium protein content (around 11%).
Chocolate chips: semi-sweet or dark chocolate work great here but milk is good too.
Start by beating the sugar and eggs together: the mix will be dark at first but you beat it will turn several shades lighter and some of the sugar will dissolve:
While beating, add the flavorings (salt & vanilla)
Once the mix is light and airy, keep the mixer on and slowly pour in the butter:
Beat to combine then add the discard and beat
Add the flour, cocoa, and baking soda.
While beating, pour in the buttermilk. Beat until Just combined (no more or the muffins will be tough).
Add the chocolate chips and stir them in (beating will break them up).
We’re going to bake the muffins so that no two are next to each other: so put a parchment liner in every other muffin cup. This will help our muffins bake tall and dome well.
Fill the muffin cups, there’s enough batter for 12 and you’ll want the cups almost all the way full
If you like, add more chocolate chips to the top
Set the trays in the fridge. This isn’t a necessary step but I find that chilling the batter helps with muffin doming
Preheat the oven and bake the muffins first at 400 F for the first 7 minutes then lower the temperature to 350 F and bake until a cake tester comes out clean (or the muffin springs back when pressed in the center).
