Why Sourdough Snickerdoodles Are So Special
Traditional snickerdoodles are already delicious, but sourdough discard transforms them into bakery-style cookies with enhanced texture and flavor.
Rich Flavor Complexity
Sourdough discard adds:
- Mild tanginess
- Deeper flavor
- Slight caramel notes
- Better overall balance
The sour flavor remains subtle while enhancing the buttery cinnamon sweetness.
Soft and Chewy Texture
One of the best things about these cookies is their texture.
They bake into:
- Soft centers
- Slightly crisp edges
- Puffy tops
- Tender crumb
The sourdough discard contributes extra moisture, helping the cookies stay soft longer.
The Perfect Use for Sourdough Discard
Many bakers look for creative ways to avoid wasting sourdough discard.
This recipe is perfect because:
- No long fermentation is needed
- Discard blends seamlessly into the dough
- The flavor becomes richer
- Texture improves naturally
It’s one of the easiest sourdough dessert recipes you can make.
What Makes a Snickerdoodle Different from Other Cookies?
Snickerdoodles stand out because of their signature:
- Cinnamon-sugar coating
- Tangy flavor from cream of tartar
- Soft chewy texture
- Crackled tops
Unlike sugar cookies, snickerdoodles have a slight tanginess and warm cinnamon coating that make them instantly recognizable.
The Importance of Cream of Tartar
Cream of tartar is one of the defining ingredients in classic snickerdoodle cookies.
It helps create:
- Slight tangy flavor
- Soft chewy texture
- Puffy appearance
- Signature snickerdoodle taste
Without cream of tartar, the cookies become more like cinnamon sugar cookies rather than true snickerdoodles.
Key Ingredients Explained
Each ingredient in these sourdough snickerdoodles plays an important role in flavor and texture.
All-Purpose Flour
Flour forms the structure of the cookies while keeping them soft and tender.
Using all-purpose flour creates:
- Balanced texture
- Soft centers
- Slight chewiness
Butter
Butter adds:
- Richness
- Moisture
- Flavor
- Tender texture
Softened butter blends smoothly into the dough and creates a light creamy consistency.
Sugar
Sugar sweetens the dough while helping create:
- Golden edges
- Soft texture
- Slight caramelization
The cinnamon sugar coating also gives the cookies their classic appearance.
Sourdough Discard
Sourdough discard contributes:
- Mild tang
- Moisture
- Texture improvement
- Flavor depth
Even unfed discard works beautifully in this recipe.
Egg
Egg provides:
- Structure
- Richness
- Stability
- Soft texture
It also helps bind the dough together.
Vanilla Extract
Vanilla enhances the buttery and cinnamon flavors while adding warmth and sweetness.
Cinnamon
Ground cinnamon gives snickerdoodles their signature cozy flavor.
It creates:
- Warm aroma
- Sweet spice
- Classic bakery taste
Baking Soda
Baking soda helps the cookies:
- Rise slightly
- Spread properly
- Develop soft texture
Salt
Salt balances sweetness while intensifying the flavor of butter and cinnamon.
Why Cinnamon Sugar Coating Matters
The cinnamon sugar coating creates the iconic snickerdoodle finish.
As the cookies bake:
- Sugar caramelizes slightly
- Cinnamon becomes aromatic
- Exterior develops delicate crispness
This coating is what gives snickerdoodles their unmistakable flavor and texture.
Step-by-Step Guide to Making Sourdough Snickerdoodles
Step 1: Prepare the Oven and Baking Sheet
Preheat the oven to:
375°F (190°C)
Line baking sheets with:
- Parchment paper
or - Silicone baking mats
This prevents sticking and promotes even baking.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together:
- Flour
- Cream of tartar
- Baking soda
- Salt
- Cinnamon
Mixing dry ingredients first ensures:
- Even spice distribution
- Consistent texture
- Proper leavening
Step 3: Cream Butter and Sugar
In a separate bowl, beat:
- Softened butter
- Sugar
until light and creamy.
This step helps create:
- Fluffy texture
- Better cookie spread
- Soft crumb
The sugar should begin dissolving into the butter.
Step 4: Add Wet Ingredients
Add:
- Sourdough discard
- Egg
- Vanilla extract
Mix until smooth and fully incorporated.
The dough becomes creamy and slightly glossy.
Why Sourdough Improves Cookie Texture
Sourdough discard naturally adds moisture to the dough.
This helps create:
- Softer cookies
- Longer-lasting freshness
- Chewy texture
The subtle acidity also enhances flavor complexity.
Step 5: Combine Wet and Dry Ingredients
Gradually add the wet mixture into the dry ingredients.
Mix until just combined.
Avoid overmixing because it can create:
- Dense cookies
- Tough texture
- Excess spreading
The dough should feel soft but manageable.
Understanding the Dough Texture
Proper snickerdoodle dough should be:
- Soft
- Slightly thick
- Easy to scoop
- Not overly sticky
If needed, lightly dust with extra flour.
Step 6: Make the Cinnamon Sugar Coating
In a small bowl, combine:
- Sugar
- Cinnamon
Mix thoroughly.
This coating creates the classic snickerdoodle exterior.
Step 7: Shape the Dough Balls
Using a cookie scoop, portion the dough into evenly sized balls.
Uniform sizing ensures:
- Even baking
- Consistent texture
- Professional appearance
Step 8: Coat in Cinnamon Sugar
Roll each dough ball thoroughly in the cinnamon sugar mixture.
Ensure all sides are evenly coated for maximum flavor.
Step 9: Bake the Cookies
Place the coated dough balls onto prepared baking sheets.
Bake for:
11–12 minutes
until:
- Cookies puff slightly
- Edges turn lightly golden
- Centers remain soft
Do not overbake for best texture.
Why Slight Underbaking Creates Better Cookies
Snickerdoodles continue baking slightly after removal from the oven.
Removing them while slightly soft creates:
- Chewy centers
- Tender texture
- Better moisture retention
Overbaking may result in dry cookies.
Step 10: Cool Before Serving
Allow cookies to cool on the baking sheet briefly before transferring to a wire rack.
Cooling helps:
- Set texture
- Develop chewiness
- Prevent breaking
Flavor Development Over Time
Interestingly, these cookies often taste even better the next day.
As they rest:
- Cinnamon flavor deepens
- Sourdough tang becomes balanced
- Texture softens further
This makes them excellent make-ahead cookies.
Make-Ahead Instructions
You can refrigerate the dough for up to:
3 days
before baking.
This longer resting period enhances:
- Flavor depth
- Texture
- Caramel notes
Freezing Instructions
Freezing Unbaked Dough
Freeze plain dough balls without cinnamon sugar coating.
When ready to bake:
- Thaw in refrigerator
- Roll in cinnamon sugar
- Bake as directed
Freezing Baked Cookies

3 months
Storage Tips

up to 1 week
This helps maintain their soft chewy texture.
Delicious Variations
Brown Butter Snickerdoodles
Brown the butter first for deeper caramel flavor.
Maple Cinnamon Cookies
Replace some sugar with maple sugar for richer sweetness.
Extra Cinnamon Spice
Add additional cinnamon for stronger spice flavor.
