🍪 🍋 Sourdough Key Lime Glazed Cookies 🍪 🍋
Soft Sourdough Discard Key Lime Cookies with Sweet Citrus Glaze
🍴 Ingredients
🍪 For the Cookies
🧈 1/2 cup unsalted butter, softened
🍚 3/4 cup granulated sugar
🍞 1/4 cup sourdough discard
🥚 1 large egg
🍋 2 tbsp fresh key lime juice
🍈 1 tbsp key lime zest
🌾 1 1/2 cups all-purpose flour
🥄 1/2 tsp baking soda
🧂 1/4 tsp salt
🍋 For the Key Lime Glaze
🍚 1 cup powdered sugar
🍈 2 tbsp fresh key lime juice
📋 Directions
1️⃣ Preheat the Oven: Preheat your oven to 175°C (350°F). Line a baking sheet with parchment paper to prevent the cookies from sticking.
2️⃣ Cream the Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar together for 2-3 minutes until the mixture becomes light and fluffy.
3️⃣ Add the Wet Ingredients: Mix in the sourdough discard and egg until smooth. Add the fresh key lime juice and key lime zest, stirring until everything is well combined.
4️⃣ Combine the Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
5️⃣ Make the Dough: Gradually add the dry ingredients to the wet mixture. Stir gently until a soft cookie dough forms. Avoid overmixing to keep the cookies tender.
6️⃣ Chill the Dough: Refrigerate the dough for 20-30 minutes. This helps the cookies hold their shape and improves their texture during baking.
7️⃣ Shape the Cookies: Scoop tablespoon-sized portions of dough onto the prepared baking sheet, leaving about 5 cm (2 inches) between each cookie. Gently flatten the tops if needed.
8️⃣ Bake the Cookies: Bake for 10-13 minutes, or until the edges are lightly golden and the centers look set. The cookies should remain pale for a soft, tender texture.
9️⃣ Cool Completely: Let the cookies rest on the baking sheet for 5 minutes before transferring them to a wire rack. Allow them to cool completely before adding the glaze.
🔟 Prepare the Key Lime Glaze: In a small bowl, whisk together the powdered sugar and key lime juice until smooth. Add a few extra drops of lime juice if the glaze is too thick, or a little more powdered sugar if it is too thin.
1️⃣1️⃣ Glaze and Decorate: Spoon or drizzle the glaze over the cooled cookies. Sprinkle with a little extra key lime zest for a fresh citrus finish, if desired.
1️⃣2️⃣ Let the Glaze Set: Allow the glaze to set for 15-20 minutes before serving. Enjoy these soft, tangy cookies with your favorite tea, coffee, or a refreshing glass of lemonade!
