Essential Ingredients for Perfect sourdough discard oatmeal cookies

Let me tell you about the stars of the show! These ingredients work together to create a cookie that’s soft, chewy, and downright delicious.

• Sourdough Discard: This is what gives the cookies their slight tang and extra depth. Make sure it’s at room temperature for the best results. If you don’t bake sourdough, swap it for 1/4 cup milk or cream—but you’ll miss that unique flavor!
• Brown Sugar: Packed brown sugar keeps the cookies moist and brings that signature caramel-like sweetness.
• Whole Wheat Pastry Flour: This adds a nutty flavor without making the cookies heavy. If you don’t have it, all-purpose flour works too!
• Dried Currants: These little bursts of sweetness are a personal favorite, but raisins, dried cranberries, or even chopped dried apricots are excellent alternatives.
