Classic sourdough lemon crinkle cookies blend the subtle tang of fermented dough with bright citrus notes. The tender, chewy centers contrast beautifully with their signature crackled exterior, all beneath a delicate dusting of powdered sugar.
Key Ingredients
- All Purpose Flour: Measured precisely for ideal cookie structure

- Fed Sourdough Starter: 100% hydration, adds complexity and texture
- Fresh Lemons: Both zest and juice provide natural flavor
- Pure Vanilla: Enhances overall taste profile
- Large Egg Yolk: Room temperature for smooth incorporation
- Confectioners Sugar: Creates signature coating

Preparation Method
- Setup:
- Allow ingredients to reach room temperature. Zest lemons before juicing. Measure ingredients accurately.
- Mixing:
- Beat butter and sugar until light, 3-4 minutes. Incorporate wet ingredients gradually. Fold dry ingredients just until combined.
- Chilling:
- Rest dough in refrigerator until firm for best texture and shape.
- Shaping:
- Portion into uniform balls, coat thoroughly in powdered sugar.

Baking Instructions
Space cookies evenly on baking sheets. Monitor closely - edges should set while centers remain soft. Surface will naturally crack during baking. Remove when puffed but before excessive browning occurs. Cool briefly on pan before transferring.
Storage Guidelines
Store between parchment layers in sealed container at room temperature up to 5 days. For extended storage, freeze unsugared dough balls. Thaw in refrigerator, coat in sugar, then bake as directed.
Recipe Variations
Adapt the recipe using orange or lime citrus. Consider adding lavender buds, white chocolate, or fresh herbs like thyme. Each variation maintains the classic crinkled texture while offering unique flavor profiles.
Serving Suggestions
Display on tiered stands or platters garnished with citrus slices and herbs. Refresh powdered sugar coating if needed before serving. Package carefully between parchment for gifting.

These artisanal cookies showcase the perfect harmony between sourdough and citrus. Careful attention to temperature, timing and technique yields consistently beautiful and flavorful results. They make an elegant addition to any gathering or gift basket.
Frequently Asked Questions
- → Why does the dough need to be chilled?
- Chilling keeps the dough firm for shaping, builds flavor, and helps the cookies stay thick and not spread out in the oven.
- → Can I swap out discard for active sourdough starter?
- Of course! Both discard and active starter will work here since leavening isn’t a factor in this recipe.
- → What's the sign the cookies are baked enough?
- Check for firm edges while the centers still look puffed and slightly gooey. They’ll continue to firm up as they cool.
- → Is freezing the cookie dough an option?
- Yep! Roll the dough into balls (without sugar coating), then freeze for up to three months and bake whenever you’re ready.
- → My cookies didn’t crackle. What went wrong?
- Be sure to coat the dough balls generously in the powdered sugar and don’t skip chilling the dough before baking!
