Ingredients

This sourdough discard muffins recipe relies on everyday ingredients you probably already have hanging out in your pantry and fridge.

For the wet ingredients—butter, coconut oil, eggs, milk, vanilla, and sourdough discard—you’ll want everything at room temperature so it blends smoothly without streaks. For the dry mix—flour, sugar, baking powder, baking soda, and salt—whisk them together first to distribute the leavening evenly and avoid clumpy surprises.

Amount	Ingredient
2¾ cups (330g)	all-purpose flour
2 tsp (8g)	baking powder
½ tsp (2g)	baking soda
½ tsp (2g)	sea salt
8 tbsp (113g)	unsalted butter, room temperature—yes, real butter; margarine just doesn’t cut it here
2 tbsp (27g)	coconut oil, melted
1 cup (200g)	granulated sugar
2 large	eggs, room temperature
2 tsp (9g)	vanilla extract—the good stuff makes a difference
½ cup (150g)	sourdough discard—doesn’t matter if it’s fed or unfed
¾ cup (184g)	whole milk
1 cup (200g)	semi-sweet chocolate chips—or as many as your heart desires

Tools You’ll Actually Use

You don’t need a fancy kitchen to nail these muffins. Here’s what you’ll actually reach for:

• Medium mixing bowl
• Stand mixer or hand mixer
• Whisk
• Rubber spatula
• Standard 12-cup muffin pan (you’ll bake in two batches)
• Paper liners or cooking spray
• Measuring cups and spoons
• Cooling rack

Step-by-Step Instructions

Let’s make these sourdough chocolate chip muffins happen—they’re easier than you think.

Step 1: Prep Your Oven and Dry Ingredients

Preheat your oven to 350°F (177°C) and position a rack in the lower center spot. In a medium mixing bowl, whisk together the all-purpose flour, sea salt, baking powder, and baking soda until everything’s evenly distributed and there are no clumps hiding.

Set this bowl aside while you work on the wet ingredients—this gives the baking powder and soda a chance to wake up.

Step 2: Cream the Butter, Coconut Oil, and Sugar

In your stand mixer or using a hand mixer, beat together the room-temperature unsalted butter, melted coconut oil, and granulated sugar on medium-high speed for a full 5 minutes, scraping down the sides of the bowl as needed.

You’re looking for a fluffy, pale, aerated mixture that’s increased in volume—this is what gives your muffins that tender, bakery-style crumb. Don’t rush this step; the air you’re incorporating now is doing serious work.

Step 3: Add Eggs and Sourdough Mixture

Add the eggs to your creamed butter-sugar mixture one at a time, beating after each addition until it’s fully incorporated and the mixture looks smooth and cohesive. Then mix in the sourdough discard, whole milk, and vanilla extract, scraping down the sides of the bowl to make sure everything’s combining evenly.

The batter might look a little curdled at this point—that’s totally normal and will smooth out when you add the flour.

Step 4: Combine Wet and Dry Ingredients

Add your dry ingredient mixture to the wet ingredients all at once, then mix on low speed until you achieve a thick, lump-free batter that’s just combined.

Stop mixing as soon as you don’t see any flour streaks—over-mixing develops the gluten and gives you tough, dense muffins instead of tender ones. The batter should be thick enough to hold its shape but still scoop-able.

Step 5: Fold in the Chocolate Chips

Gently fold the semi-sweet chocolate chips into your muffin batter using a rubber spatula, distributing them throughout without deflating all that beautiful air you whipped in earlier. Save a few chips to press into the tops if you want that professional bakery look—totally optional but Instagram-worthy.

Step 6: Fill the Muffin Cups

Place paper liners in your standard 12-cup muffin pan, or grease the cups generously with cooking spray if you’re going liner-free.

Fill each cup completely with approximately ⅓ cup of batter—these muffins rise beautifully, so don’t be shy about filling them to the top. You’ll have enough batter for 16 muffins total, so you’ll need to bake in two batches or use a second pan.

Step 7: Bake Until Golden and Irresistible

Place your filled muffin pan on the lower center rack of your preheated 350°F (177°C) oven and bake for 25-28 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with just a few moist crumbs clinging to it.

The tops should be golden brown with slightly domed peaks, and your kitchen should smell like a cozy café on a Sunday morning. Avoid over-baking or you’ll lose that tender, moist texture.

Step 8: Cool and Resist Temptation

Let the muffins cool in the pan for 10 minutes—this helps them set and prevents them from falling apart when you move them. Then transfer them to a cooling rack to finish cooling completely. Or, you know, grab one while it’s still warm and let the melty chocolate chips do their thing. I won’t judge.

Claire’s Pro Tips & Gentle Guidance

These sourdough discard muffins easy tricks will take your batch from good to absolutely crave-worthy.

Room Temperature Ingredients Are Your Secret Weapon

I learned this the hard way after producing a batch of streaky, weirdly textured muffins—cold eggs and butter don’t emulsify properly with the sugar, which means your batter won’t trap air as efficiently. Set everything out about an hour before you start baking, or quick-warm your eggs by placing them in a bowl of warm water for 5 minutes.

Don’t Skip the Full 5-Minute Creaming Time

It feels excessive, I know, but those 5 minutes of beating butter, coconut oil, and sugar are what create the light, fluffy texture that makes these muffins taste bakery-bought. According to Serious Eats‘ detailed creaming guide, proper creaming incorporates tiny air pockets that expand during baking—and skimping here gives you dense, flat muffins.

Measure Flour Correctly or Risk Dense Muffins

Scooping flour directly from the bag packs it down and can give you up to 25% more flour than the recipe calls for, which leads to dry, hockey-puck muffins. Instead, fluff your flour with a spoon, then gently spoon it into your measuring cup and level it off with a knife. Or better yet, use a kitchen scale and measure 330g—it’s foolproof.

Your Sourdough Discard’s Age Doesn’t Matter

Whether your discard is fresh from this morning’s feeding or has been hanging out in the fridge for two weeks, it’ll work beautifully here. Older discard actually adds more tangy flavor, which plays nicely against the sweet chocolate chips. Just give it a good stir before measuring since it tends to separate.

Fill Those Cups All the Way

I used to timidly fill muffin cups halfway, thinking they’d overflow—they never did, and I ended up with sad, flat-topped muffins. These babies need a full ⅓ cup of batter to get that gorgeous bakery-style dome and tender crumb. Trust the recipe and fill them generously.

Quick Fixes for Sourdough Chocolate Chip Muffins

Problem: Muffins Are Dense and Heavy

You probably over-mixed the batter after adding the flour, which developed too much gluten. Mix just until you don’t see dry flour streaks—about 15-20 gentle folds with a spatula. The batter should still look slightly lumpy, and that’s perfectly fine.

Problem: Muffins Are Dry and Crumbly

This usually means you’ve added too much flour (see my measuring tip above) or over-baked them. Check your muffins at 25 minutes—the toothpick should come out with a few moist crumbs, not completely clean. Also, make sure you’re storing them in an airtight container; these muffins dry out quickly when exposed to air.

Problem: Chocolate Chips Sank to the Bottom

Toss your chocolate chips in a tablespoon of flour before folding them into the batter—this helps them stay suspended instead of sinking during baking. Also, make sure your batter is thick enough; if it’s too thin, chips will migrate downward as the muffins bake.

Problem: Muffins Stuck to the Pan

If you skipped the liners and didn’t grease thoroughly enough, you’ll have a mess. Next time, either use paper liners or spray your pan generously with cooking spray, making sure to get into all the corners. Let the muffins cool for the full 10 minutes before trying to remove them—they need that time to set and release naturally.

Variations & Fun Twists

This sourdough recipes for kids base is crazy versatile—here’s how to make it your own.

Seasonal Swaps

Swap the chocolate chips for fresh blueberries or diced strawberries in spring and summer, or try dried cranberries and white chocolate chips for a holiday vibe. In fall, fold in chopped pecans and a teaspoon of cinnamon for an autumn-spiced version that pairs perfectly with morning coffee.

Gluten-Free Option

Replace the all-purpose flour with a 1:1 gluten-free baking blend (I like King Arthur or Bob’s Red Mill), and add an extra ¼ teaspoon of xanthan gum if your blend doesn’t already include it. The texture will be slightly more delicate, but still absolutely delicious.

Vegan Twist

Substitute the butter with vegan butter, use flax eggs (2 tablespoons ground flaxseed mixed with 6 tablespoons water, let sit 5 minutes), swap the whole milk for oat or almond milk, and choose dairy-free chocolate chips. The texture will be a touch denser but still tender and moist.

Bakery-Style Finishing Touch

Before baking, press a few extra chocolate chips into the tops of your muffins and sprinkle with coarse sugar for that professional bakery look. It’s totally extra, but sometimes extra is exactly what Tuesday morning needs.

Serving, Storage & Reheating

These sourdough chocolate chip muffins are best enjoyed warm, but they keep beautifully for grab-and-go breakfasts all week long.

Serve these muffins slightly warm with a pat of salted butter melting into the top, or let them cool completely for lunchbox treats that won’t fall apart in transit. They’re perfect alongside scrambled eggs for a complete breakfast, or as an after-school snack with a glass of cold milk.

Store cooled muffins in an airtight container at room temperature for up to 3 days, or refrigerate them for up to a week if your kitchen runs warm. The fridge dries them out slightly, but a quick reheat brings them back to life.

To reheat, microwave individual muffins for 15-20 seconds until just warm, or wrap them in foil and warm in a 300°F oven for 10 minutes. The chocolate chips get melty again and the whole thing tastes freshly baked—pure magic.

No-Waste Kitchen Magic

Got leftover muffins that are going stale? Cube them up and use them as a base for a decadent bread pudding drizzled with caramel sauce.

You can also freeze day-old muffins, then blitz them in a food processor to create sweet muffin crumbs for topping yogurt parfaits or ice cream sundaes. Or go full dessert mode and slice them in half, butter both sides, and griddle them until crispy for an indulgent breakfast treat that tastes like French toast met a chocolate chip cookie.

Save your empty sourdough discard jar and use it to mix the wet ingredients directly—one less bowl to wash and you’ll scrape out every last bit of that tangy discard.
