Quick and Easy Sourdough Lemon Shortbread Cookies: A Simple Step-by-Step Process
Let’s Get Cooking!
Cream the Butter and Sugar: In the bowl of a stand mixer fitted with the paddle attachment, cream together the softened butter, granulated sugar, and lemon zest until light and fluffy, about 3-5 minutes. (If you don’t have a stand mixer, a hand mixer or even a good old wooden spoon will do the trick.)
Mix in the Sourdough Starter: Add in your sourdough starter, salt, and vanilla extract, mixing until everything is just combined. The dough will begin to come together beautifully, and that heavenly lemony smell will fill your kitchen, seriously, it’s amazing!
Incorporate the Flour: Gradually add the flour, mixing gently until it’s just combined. You want a soft dough, so don’t overdo it!
Shape the Dough: Transfer the dough onto a clean work surface (no flour needed here). Roll it into a log shape about 1.5 inches in diameter.
Sugar Coating: Grab that granulated sugar! Pour the remaining 2 tablespoons onto your work surface, and roll the log of dough in the sugar until coated all over. Such a nice touch!
Chill or Bake: You can either bake immediately or chill the dough for up to 48 hours for a longer fermentation (which adds more flavor). If chilling, wrap the rolls in plastic wrap.
Preheat the Oven: When you’re ready to bake, preheat your oven to 350°F (175°C).
Slice and Bake: Cut the dough into ½ inch slices and place them on a parchment-lined baking sheet. Bake for about 12-15 minutes or until the edges are lightly golden and they smell utterly delightful!
Make the Lemon Glaze: While the cookies cool, whisk together the powdered sugar, 2 tablespoons of lemon juice, and ½ teaspoon of lemon zest until smooth.
Glaze the Cookies: Once the cookies are cool, drizzle them with the lemon glaze and brush with melted butter for extra richness. Let them set before you dig in!
