- 2 ½ cups all-purpose flour (for a gluten-free twist, try a 1:1 gluten-free baking flour)
- 1 teaspoon baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ¾ cup unsalted butter, softened (or coconut oil for a dairy-free option)
- 1 cup granulated sugar
- 1 large egg, at room temperature
- 2 teaspoons vanilla extract
- Zest of 2 large lemons (about 2 tablespoons)
- 3 tablespoons fresh lemon juice (preferably from those same lemons!)
- ½ cup buttermilk (or substitute with ½ cup milk plus 1 teaspoon white vinegar, let sit 5 minutes)
- ½ cup powdered sugar (for rolling the cookies before baking)
Back on our farm, we rarely measured precisely — Mama Lu would say, “A pinch of this, a handful of that,” but for these cookies, I find exact measurements help keep that soft texture just right, especially when baking in a new kitchen far from home.
