Tangy, sweet and loaded with bold lemon flavor, you’ll love these Sourdough Lemon Cookie Pies. Two soft, chewy cookies with a fresh lemon filling sandwiched in the middle, you’ll love these bright zesty treats.
Lemon desserts are a favorite in my household, I jump at any opportunity to develop these recipes since I know they’ll get gobbled up! That’s why I got so excited when I saw the recipe for these Lemon Pie Cookies in my friend Mimi Council’s new cookbook Effortless Eggless Baking. Mimi founded the very first organic bakery in the United States and she first specialized in cookies, so I knew these would be absolutely delicious. An added bonus is that they are eggless, and since so many of you have asked me for eggless recipes, I wanted to share this recipe with you.

Adding a Sourdough Twist
Mimi was kind enough to let me share and add a sourdough twist to her Lemon Pie Cookie! So, after a few rounds of tests, I was able to create a faithful reproduction of her recipe with the addition of sourdough discard. To convert these cookies into sourdough cookies, I took out a little bit of the milk (56 grams) and all-purpose flour (56 grams) from the original recipe and added 113 grams (½ cup) sourdough discard.
Although Mimi’s recipe was ofcourse perfect, I changed a few more things. Her original recipe uses salted butter, but I wanted to test this recipe with unsalted butter since it's what most bakers have at home. Since I was using unsalted butter, I added ½ teaspoon of salt to this recipe. I also had to use lemon extract instead of lemon flavor, which Mimi used in her recipe, since it was what I had in the pantry.
Baking with sourdough discard
Sourdough discard adds a great flavor to these cookies. Since you are not using it to make bread, your sourdough starter does not need to be activated or fed for it to work in this cookie recipe. So, you can use your discard directly from the fridge. Older discard will have a tangier, acidic flavor than freshly-fed sourdough starter. Both will work for these Sourdough Lemon Cookie Pies. You’ll get a slightly different result but your cookies will still be delicious!
Unsalted butter: imparts richness and binds the ingredients together, creaming the butter is extremely important since it helps give these cookies their delicious chewy texture
Powdered sugar and cane sugar: imparts sweetness
Milk: adds richness and binds the ingredients in these cookies
Sourdough discard: adds a delicious tang and moisture to these cookies so they taste fresher for longer
Lemon extract: imparts an intense lemon flavor to these cookies (use 2 teaspoons lemon flavor instead of 1 teaspoon lemon extract if you have it)
All-purpose flour: the low protein content is perfect for making tender, chewy cookies
Baking powder: the main raising agent, tenderizes and imparts softness to these cookies
Salt: brings out the flavor of the remaining ingredients
Lemon: this recipe calls for 1 lemon, you’ll be using the zest for the cookie dough and juice for the filling
Powdered sugar: make sure to sift your powdered sugar to get rid of any lumps so your filling will be smooth and creamy
1. Cream butter, sugars and lemon extract together until light and fluffy
2. Add in the milk and sourdough discard (your mixture may appear curdled and separated; this is totally normal!)
3. Fold in the all-purpose flour, baking powder, salt and lemon zest
4. Chill the dough for 15 to 20 minutes until the dough is a little less sticky
5. Portion out the dough and bake for 11 to 14 minutes at 375 F
6. Make the filling
7. Match up the cookies that are the most similar in size
8. Pipe the filling on half of the cookies and sandwich them together
The potency of the flavor of discard depends on your unique starter. Older discard will have a tangier, acidic flavor than freshly-fed sourdough starter. These cookies do have a sour flavor but the prominent flavor is lemon and not from sourdough.
Absolutely! You can make the cookie dough up to 3 days in advance. Portion out your cookie dough and refrigerate them on a parchment-lined cookie sheet covered with plastic wrap.
Absolutely! Simply use the same proportion of freshly fed sourdough starter in the recipe. Your starter won’t add a strong tangy flavor to your cookies, but will still work.
If you don’t have a starter, but still want to try out this recipe, simply add 56 grams of all-purpose flour and 56 grams of water to your cookie dough.
These cookies last about 3 days stored in an airtight container in the refrigerator.
