Ingredients
Wet ingredients
- 113 grams unsalted butter (softened)
- 150 grams sugar
- 50 grams brown sugar
- 80 grams sourdough discard (room temperature, active starter can be used )
- 1 large egg yolk (room temp)
- 2 teaspoons vanilla extract
- zest of 1 medium lemon
Dry Ingredients
- 200 grams all-purpose flour
- 20 grams cornstarch
- 3 grams (1/2 teaspoon) baking soda
- 3 grams (1/2 teaspoon) salt
Lemon cream filling
- 85 grams vegetable shortening (butter works too, but the filling won't be as white)
- 28 grams unsalted butter (softened )
- 170 grams powdered sugar (sifted )
- 1/2 teaspoon vanilla extract
- 1 tablespoon fresh lemon juice
- zest of 1/2 a lemon (optional but recommended )
- 1-2 teaspoons milk as needed (for consistency )
Instructions
-
Cream together the softened butter, sugar, and brown sugar until light and fluffy (about 2-3 minutes).
-
Next add the sourdough discard, egg yolk, vanilla extract, and lemon zest until smooth.
-
To the same bowl add the flour, cornstarch, baking soda, and salt.
-
Mix until a soft dough is formed (it's okay if its a bit tacky, a chill in the fridge will help this)
-
Cut 1 large piece of parchment paper and dust it with flour. Roll the dough out on the parchment paper as even as possible—about 1/4 inch thick. Tip: Lightly flour your rolling pin to prevent sticking.
-
Place the rolled out dough on a large baking tray, cover it and place it into the refrigerator for 1-24 hours (The longer chill time deepens the flavor and makes the dough much easier to handle).
Shape and bake the sourdough lemon Oreo cookies
-
Once ready to bake the sourdough lemon Oreo cookies, preheat the oven to 350 degrees F.
-
Remove the sheet of dough from the fridge and place it face-down on a lightly floured surface and gently peel off the parchment paper. (You can reuse that same parchment to line your baking sheet.)
-
Cut as many 2-inch circles as possible and transfer them to your baking sheet.
-
Any additional dough will need to be rolled out and cut. If the dough seems sticky add some flour or place it in the freezer to firm up.
-
Bake the sourdough lemon Oreo cookies for 12-14 minutes for that crispy finish (if you’d prefer a softer cookie bake for 8-10 minutes).
-
Allow them to cool on the pan and cool completely before filling. They crisp up as they cool.
Make the lemon cream filling
-
To a bowl beat the shortening and butter until smooth and fluffy. Add the sifted powdered sugar and mix until combined.
-
Mix in vanilla, lemon juice, and zest. Add milk as needed for a smooth, pibeable consistency.
-
Pipe or spoon ~1 tablespoon filling onto one cookie (bottom side up) and gently press a second cook on top.
-
Once all sandwich cookies have been assembled, place them in the fridge for 10 minutes to set and enjoy!
