Ingredients You’ll Need

1 cup sourdough discard: Using sourdough discard adds a unique flavor and moisture to the muffins. If you don’t have sourdough discard, you can substitute it with plain yogurt or buttermilk, though the taste will differ slightly.
2 ripe bananas (mashed): Ripe bananas are key here; they provide natural sweetness and moisture. If you don’t have ripe bananas, let your bananas sit on the counter until they’re brown and fragrant.
1/2 cup granulated sugar: This adds sweetness and helps create that tender muffin texture. You can adjust this amount based on your sweetness preference or use coconut sugar for a lower glycemic option.
1/4 cup brown sugar: This gives a deeper, caramel-like flavor. Light or dark brown sugar will work; just keep in mind that dark brown will add more moisture.
1/2 cup melted butter or oil: Both options yield delicious results. Butter enhances flavor, while oil keeps the muffins tender. Use coconut oil for a subtle coconut flavor.
2 large eggs: They provide structure and stability to the muffins. For an egg-free version, you can substitute two tablespoons of ground flaxseed mixed with six tablespoons of water.
1 teaspoon vanilla extract: Adds warmth and richness. Using pure vanilla extract makes a noticeable difference in flavor.
1 1/2 cups all-purpose flour: All-purpose flour creates the ideal muffin texture. If you want a healthier version, you can replace some flour with whole wheat flour, but adjust the liquid if needed.
1 teaspoon baking soda: This is the leavening agent that helps the muffins rise. Make sure it’s fresh for best results.
1/2 teaspoon salt: Balances the sweetness and enhances overall flavor.
3/4 cup chocolate chips: Semi-sweet or dark chocolate chips work perfectly. You can also use mini chocolate chips for a fun twist or swap for nuts if preferred.

How to Make Sourdough Banana Chocolate Chip Muffins

Preheat the Oven: Begin by preheating your oven to 350°F (175°C) and lining a muffin tin with paper liners. This ensures easy removal after baking and minimizes mess.
Mash the Bananas: In a large mixing bowl, mash the ripe bananas until they are smooth and creamy. The riper they are, the sweeter your muffins will be—so don’t shy away from those brown spots!
Combine Wet Ingredients: Add the sourdough discard, eggs, granulated sugar, melted butter, and vanilla extract to the mashed bananas. Mix everything until well combined and smooth.
Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This step ensures that the baking soda is evenly distributed throughout the flour.
Combine Batter: Gradually add the dry mixture to the wet ingredients, gently folding to combine. Be careful not to overmix, as you want the muffins to remain light and fluffy!
Add Chocolate Chips: Fold in the chocolate chips until they’re evenly distributed throughout the batter. The chunks of chocolate will melt beautifully into the muffins as they bake.
Fill Muffin Tin: Using a spoon or ice cream scoop, fill each muffin cup about 3/4 full with batter. This will allow room for them to rise without overflowing.
Bake: Place the muffins in the preheated oven and bake for 18–22 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean.
Cool Down: Once baked, let the muffins cool in the pan for about 5 minutes before transferring them to a wire rack. This prevents them from steaming in the pan and keeps the bottoms nice and crisp.

Storing & Reheating

Store your muffins at room temperature in an airtight container for up to three days. For longer storage, place them in the fridge for up to a week, or freeze them in a zip-top bag for up to three months. To reheat, just pop them in the microwave for a few seconds or warm them in a preheated oven at 350°F (175°C) for about 5-10 minutes. Keep in mind that freezing may change the texture slightly, but a quick reheat brings back the moisture and flavor!

Chef’s Helpful Tips

Make sure your sourdough discard is at room temperature for the best blending with other ingredients; cold batter can lead to denser muffins.
Avoid overmixing the batter—this is key for a tender muffin. A few lumps are perfectly fine!
If your bananas aren’t quite ripe enough, you can microwave them for 30 seconds to a minute until they soften.
To enhance banana flavor, consider adding a sprinkle of cinnamon or nutmeg to the dry ingredients.

These muffins are not only a great way to use up your sourdough discard, but they’re also a hit at any gathering or simply for enjoying with a cup of coffee. Once you try this recipe, you may never look at bananas and sourdough the same way again!

Recipe FAQs

Can I use frozen bananas for this recipe?

Absolutely! Just make sure to thaw them completely, and drain excess liquid before mashing. They’ll be extra sweet and flavorful.

How do I know when the muffins are finished baking?

Insert a toothpick into the center of a muffin; it should come out clean or with a few crumbs—no wet batter. If they’re still wet, give them a few more minutes in the oven.

Can I substitute the chocolate chips?

Yes! Feel free to swap the chocolate chips for chopped nuts, dried fruit, or even switch to white chocolate for a different flavor experience. The muffins will still turn out wonderfully!

What if I don’t have sourdough discard?

If you’re fresh out of sourdough discard, you can substitute it with an equal amount of plain yogurt or buttermilk. Be aware that the flavor will be slightly different but still delicious!
