📖 Instructions

1. **Prepare Your Workspace and Preheat Oven:** First things first, get your kitchen ready! Clear a clean, flat surface. Line two large baking sheets with parchment paper or silicone mats. This is super important for preventing sticking and ensuring even baking. Now, preheat your oven to 350°F (175°C). Having the oven at the right temperature from the start makes a difference.
2. **Combine Dry Ingredients (Except Freeze-Dried Strawberries):** In a medium bowl, whisk together the all-purpose flour, granulated sugar, and salt. Make sure it's really well combined so you don't get any pockets of just flour or just salt in your cookies. A good whisking makes all the difference for a consistent dough.
3. **Cream Butter and Vanilla:** In a separate, large mixing bowl, using an electric mixer (either a stand mixer with a paddle attachment or a hand mixer) cream together the softened unsalted butter and vanilla extract on medium speed until the mixture is light and fluffy. This usually takes about 2-3 minutes. This step incorporates air, which contributes to the shortbread's tender texture.
4. **Gradually Add Dry to Wet Ingredients:** Slowly add the dry flour mixture to the creamed butter mixture, mixing on low speed. Be careful not to overmix! Mix only until just combined and a soft, crumbly dough starts to form. Overmixing can lead to tough cookies, and we want tender ones!
5. **Fold in Freeze-Dried Strawberries:** Gently fold in the crushed freeze-dried strawberries. Use a spatula for this to ensure they're evenly distributed without further developing the gluten in the dough. You want those little bursts of strawberry flavor throughout!
6. **Form the Cookies:** Use a small cookie scoop (about 1.5 tablespoons, or if you don't have one, just use a spoon) to scoop out dough balls. Roll them gently between your palms to smooth them out slightly. Place the dough balls about 2 inches apart on your prepared baking sheets. Don't crowd them; they need space to spread just a tiny bit.
7. **Bake until Edges are Golden:** Transfer the baking sheets to the preheated oven. Bake for 10-12 minutes, or until the edges are lightly golden brown. The centers might still look a little pale, and that’s okay. We’re going for a tender, not overly crispy, shortbread. Keep an eye on them, as oven temperatures can vary! You might want to rotate your trays halfway through for even baking.
8. **Cool Completely:** Once baked, remove the cookies from the oven and let them cool on the baking sheets for 5 minutes. They'll be a bit delicate right out of the oven. After 5 minutes, carefully transfer them to a wire rack to cool completely. This is crucial before glazing, otherwise, your glaze will just melt off.
9. **Prepare the Glaze:** While the cookies are cooling, whisk together the powdered sugar, milk, and vanilla extract in a small bowl until smooth. You're aiming for a consistency that's thick enough to coat a spoon but thin enough to drizzle. If it’s too thick, add a tiny bit more milk; too thin, add a pinch more powdered sugar. Remember, a little goes a long way with the liquid!
10. **Glaze the Cooled Cookies:** Once the cookies are entirely cool (and I mean *completely* cool, otherwise it's a sticky mess!), drizzle the glaze over them. You can use a spoon or a small whisk for this. For a more uniform look, some folks even dip half the cookie into the glaze. Let the glazed cookies sit on the wire rack for about 15-20 minutes, or until the glaze sets. You'll know it's ready when it's no longer tacky to the touch. This step is the sweet finish that makes them truly irresistible! Enjoy your hard work; you've earned these delicious treats!
