1. Preparing the Dough

Start by preheating your oven to 325°F (163°C). This temperature ensures a gentle bake, allowing the cookies to retain their buttery tenderness. In a medium bowl, whisk together the flour, 1/2 cup confectioners’ sugar, and kosher salt. This dry mixture forms the foundation of your dough. Separately, in a large bowl, cream the softened butter, 1/4 cup confectioners’ sugar, lemon zest, and lemon juice. The key here is to beat the mixture until it’s light and fully combined, typically around 4-5 minutes. The butter should take on a fluffy texture, ensuring a soft and delicate cookie. Gradually incorporate the flour mixture on low speed, mixing until just combined. Overmixing can lead to tough cookies, so stop as soon as the ingredients are evenly distributed.

2. Shaping the Cookies

Roll the dough into 1-inch balls, aiming for uniformity to ensure even baking. Place the dough balls on a tray and chill them in the freezer for 12-15 minutes. This step helps the cookies maintain their shape during baking. Once chilled, arrange the dough balls on a baking sheet lined with parchment paper or a silicone baking mat, spacing them about 2 inches apart.

3. Baking and Indenting

Bake the cookies for 10 minutes initially. Remove them from the oven and, using the rounded part of a teaspoon or the handle of a wooden spoon, press into the center of each ball to create an indent. Be gentle to avoid cracking the edges. Return the cookies to the oven and bake for an additional 16-18 minutes, or until the bottoms are just beginning to brown. Transfer the baking sheet to a wire rack and let the cookies cool completely.

4. Making the Glaze

While the cookies cool, prepare the glaze. In a small bowl, whisk together the confectioners’ sugar, lemon juice, and raspberries. Use a fork to mash the raspberries thoroughly, distributing their vibrant pink hue and tart flavor evenly. The result should be a smooth, pourable glaze.

5. Finishing Touches

Dust the cooled cookies with a light sprinkling of confectioners’ sugar. Then, spoon or pipe the glaze into the indents of each cookie. Allow the glaze to set for at least 10 minutes before serving. The finished cookies should have a glossy center with a delicate pink tint, making them visually stunning and irresistibly inviting.
