Step‑by‑Step Instructions
- Cream together unsalted butter, powdered sugar, and cane sugar until light and fluffy. Gradually mix in lemon extract, milk, and sourdough discard until well combined.
- In a separate bowl, whisk together all-purpose flour, baking powder, salt, and lemon zest. Gradually add to wet ingredients, folding gently.
- Cover the dough with plastic wrap and refrigerate it for at least 30 minutes.
- Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Scoop out tablespoon-sized portions of dough, roll into balls, and flatten slightly. Place on the prepared baking sheet with space for spreading.
- Bake for 10-12 minutes until edges are golden and centers are just set.
- Prepare the filling by beating together powdered sugar, unsalted butter, salt, and lemon juice until creamy and smooth.
- To assemble, spread filling on the flat side of a cooled cookie and top with another cookie to create a sandwich.
Notes
Ensure butter and milk are at room temperature. Do not overmix the dough to maintain softness. Store in an airtight container for freshness up to 3 days or refrigerate for a week.
