Step-by-Step Guide
Preheat the Oven
Set your oven to 375°F (190°C). This temperature ensures the muffins bake evenly and develop a nice rise.
Line a 12-cup muffin tin with paper liners or grease it lightly with butter or oil to prevent sticking.
If using a convection oven, reduce the temperature to 350°F (175°C) to avoid overbaking.
Mix the Dry Ingredients
In a large bowl, whisk together:
- 2 cups all-purpose flour (provides structure; swap with whole wheat flour for a denser texture or gluten-free blend for GF muffins)
- ½ cup cocoa powder (adds deep chocolate flavor; Dutch-process cocoa gives a darker color and smoother taste)
- 1 teaspoon baking soda (helps the muffins rise; swap with 1 ½ teaspoons baking powder if avoiding soda)
- ½ teaspoon baking powder (adds extra lift; can be replaced with ¼ teaspoon baking soda + ½ teaspoon lemon juice for acidity)
- ½ teaspoon salt (enhances flavor; use sea salt or pink salt for a slight variation)
Whisk everything together thoroughly to ensure even distribution of leavening agents and cocoa powder.
Combine the Wet Ingredients
In another bowl, mix:
- 1 cup granulated sugar (sweetens; swap with coconut sugar for a caramel-like taste or honey for added moisture)
- ½ cup melted butter (adds richness; replace with coconut oil for a dairy-free version or vegetable oil for a lighter texture)
- 2 large eggs (binds the ingredients; swap with flax eggs for a vegan option)
- 1 teaspoon vanilla extract (enhances aroma; almond or maple extract adds a unique twist)
- 1 cup sourdough starter discard (adds moisture and a slight tang; can be replaced with ½ cup yogurt + ½ cup extra milk)
- ½ cup whole milk (keeps muffins soft; swap with almond, oat, or buttermilk for different flavors)
Whisk until the mixture is smooth and well combined. Ensure the eggs are fully incorporated.
Combine Wet & Dry Ingredients
Gradually pour the wet mixture into the dry ingredients.
Stir gently! Overmixing develops gluten, making the muffins tough instead of soft and fluffy.
Mix until just combined—some lumps are okay!
Fold in the Chocolate
Gently stir in 1 cup semisweet chocolate chunks or chips (swap with dark chocolate for an intense flavor or white chocolate for a sweeter contrast).
Ensure even distribution, but avoid overmixing.
Fill & Bake
Divide the batter evenly among the muffin cups, filling each about ¾ full to allow room for rising.
If desired, sprinkle extra chocolate chunks on top for an extra chocolatey touch.
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
If using a convection oven, check for doneness at 16 minutes as they may bake faster.
Cool & Enjoy
Let the muffins cool in the tin for 5 minutes—this helps them set and makes removal easier.
Transfer them to a wire rack to cool completely. This prevents sogginess from trapped steam.
Enjoy warm, or store them in an airtight container at room temperature for up to 3 days.
For longer storage, freeze for up to 3 months—just reheat in the microwave for 20 seconds to enjoy fresh-baked goodness!
