Why You’ll Love These Sourdough Banana Bread Muffins

These muffins are like the unicorns of the breakfast muffins: they hit that perfect sweet spot between healthy and indulgent. They are great for breakfast, snack time, or midnight bites — no judgment here. Plus, you’ll never waste brown bananas again. 

• They’re super moist from the ripe bananas and sourdough discard.
• Rich, melty chocolate chips make them feel like a dessert.
• Thanks to the fresh-milled flour, you can feel just a little bit smug about the added nutrients.

Why Use Sourdough Discard?

Mostly to use up extra starter because I don’t feel like going through the process of making bread, but also because I hate throwing any of it out! Sourdough muffins (or quick bread recipes in general) are a great way to use up your sourdough starter discard.

Grain is expensive, and I don’t want to waste that tangy, flavorful goodness! It’s packed with fermented benefits and works beautifully in recipes where a yeasty rise isn’t the star of the show (hello, muffins!).

You can totally use active sourdough starter too, but it’s not necessary. These sourdough banana muffins will be just as tasty either way.

The Magic of Fresh Milled Flour

Fresh milled flour is like freshly ground coffee — it just tastes better. When you mill wheat berries at home, you get a whole grain flour that’s still full of nutrients, flavor, and texture that store-bought flour can’t touch. Bonus: the smell of fresh ground flour is like nutty, warm sunshine!

Are these muffins healthy? Well, let’s just say they’re healthier than a brownie. The fresh milled flour brings in fiber, vitamins, and minerals, and the bananas and brown sugar keep things lightly sweet. 

I use a grain mill to grind up my all-purpose mix of 1/3 hard white wheat, 1/3 soft white wheat, and 1/3 Kamut wheat. For muffins like these, this berry mix gives a tender crumb while still maintaining some heartiness.

Sourdough Chocolate Chip Banana Muffin Recipe

Tools

• Grain Mill
• Large bowl and medium bowl
• Muffin tin + paper liners (or grease it well)
• Stand Mixer or Hand Mixer
• Spatula
• Measuring cups/spoons
• Kitchen Scale
• Cooling Rack

Ingredients 

• 1/2 Cup Brown Sugar
• 1/2 Cup Unsalted Butter, softened
• 3 Large Ripe Bananas (about 1 cup)
• 1/2 Cup Sourdough Discard
• 2 Eggs
• 1 teaspoon Vanilla
• 1.75 Cups (350g) AP Wheat Berry Mix (1/3 Hard White, 1/3 Soft White, 1/3 Kamut)
• 3/4 teaspoon Baking Soda
• 1/2 teaspoon Salt
• 1/2 teaspoon Cinnamon

• 1/4 teaspoon Nutmeg

Step-by-Step Instructions for Sourdough Chocolate Chip Banana Muffins

Prep Your Workspace: Preheat your oven to 400 degrees and line a muffin tin or grease.

Mix Wet Ingredients: In a large mixing bowl, cream butter and brown sugar together. Add sourdough discard and bananas and beat together. Mix in eggs, vanilla, stirring until almost smooth, some chunks of banana are okay.

Mix Dry Ingredients: In a separate bowl, mill wheat berries and whisk together the flour, baking soda, salt, cinnamon, nutmeg, and ginger.

Combine: Slowly add dry with to the wet ingredients. Stir until just combined — lumps are okay, don’t overmix! Gently fold in chocolate chips.

Scoop and Rest: Dump the batter into your muffin cups, filling each until just overfull. Let batter rest on counter for 5 minutes. 

Bake: Right before placing muffins in the oven lower the temperature to 350 degrees. Bake 23-25 minutes, or until the tops are golden and a toothpick comes out clean. You can test by gently pressing into the muffins and they will spring back nicely.

Cool: Leave in the pan for 5 minutes, then move to a wire rack to finish cooling.

Notes

• Leave out the chocolate chips for less sugar
• Substitute coconut oil for butter, and honey, maple syrup, or coconut sugar for brown sugar
• You don’t have to use muffin liners, I just like them for easy handling and sharing
• Baking soda is not optional, you need a rising agent or you’ll get flat bricks

Tips for Sourdough Chocolate Chip Banana Muffins

• Don’t overmix your batter — unless you like rubbery muffins. (Nobody likes rubbery muffins.)
• Make sure to let the batter rest for at least 5 minutes, up to 15 before baking for a great fluffy texture.
• Grease the top of your muffin pan, too. That way, muffin tops don’t stick when you take them out.

Storage + Freezing Tips

Store leftovers in an airtight container on the counter for 2–3 days. For longer storage, we like to freeze them! Let them fully cool, then pop them in a freezer bag. Thaw at room temperature, or reheat in the microwave or toaster oven.

Flavor Variations

• Chopped walnuts or pecans for crunch
• Peanut butter chips for an Elvis vibe
• Blueberries or raspberries instead of chocolate chips (or in addition to!)
• A sprinkle of turbinado sugar on top before baking = bakery-style magic and crunch
