📖 Instructions

1. Before you begin your baking adventure, make sure your oven is preheating to 375°F (190°C). This ensures a consistently heated oven for perfectly baked cookies. Also, line two large baking sheets with parchment paper or silicone mats. This helps prevent sticking and makes cleanup a breeze.
2. In the large bowl of your stand mixer, or using a hand mixer with a large bowl, cream together the unsalted butter and granulated sugar until the mixture is visibly light and fluffy. This usually takes about 2-3 minutes. This step is super important for achieving that tender, airy texture in your cookies.
3. Now, add the large egg and the vanilla extract to the butter and sugar mixture. Mix on medium speed until everything is just combined. Be careful not to overmix here, as overworking can lead to tougher cookies. We want them soft and melt-in-your-mouth, right?
4. In a separate medium bowl, whisk together the all-purpose flour, baking powder, and a pinch of salt. Make sure these dry ingredients are well combined so they're evenly distributed throughout your cookie dough.
5. With your mixer on low speed, gradually add the dry ingredients to the wet ingredients, a little at a time. Mix only until the flour is just incorporated and the dough comes together. The dough should look smooth and cohesive, not sticky. Again, resist the urge to overmix! Seriously, it's a cookie killer.
6. Lightly flour a clean work surface. Turn the cookie dough out onto the floured surface. Using a rolling pin, roll the dough out to about 1/4 inch thickness. For those perfectly shaped cookies, try to keep the thickness consistent across the entire sheet of dough.
7. Grab your favorite cookie cutters! Cut out shapes from the rolled dough and carefully transfer them to your prepared baking sheets, leaving about 1 inch of space between each cookie. Re-roll any dough scraps and cut out more cookies until all the dough is used up.
8. Bake the cookies for 8-10 minutes, or until the edges are very lightly golden and the centers look just set. The exact time can vary depending on your oven, so keep an eye on them! You don't want them to brown too much; they should still be soft and pale for that classic sugar cookie look.
9. Once baked, immediately transfer the cookies from the hot baking sheets to a wire rack. Let them cool completely before you even think about glazing them. This prevents the glaze from melting and running off, and also ensures the cookies are sturdy enough to handle.
10. While the cookies are cooling, let's make that luscious lemon glaze! In a medium bowl, whisk together the powdered sugar, fresh lemon juice, and the lemon zest. Keep whisking until the mixture is smooth and has a pourable, yet thick, consistency. If it's too thick, add a tiny bit more lemon juice (a quarter teaspoon at a time). If it's too thin, add a bit more powdered sugar. It’s all about finding that perfect balance.
11. Once the cookies are totally cool, it's time for the fun part – glazing! You can dip the tops of each cookie into the glaze, or use a spoon to drizzle it over them. Feel free to get creative with your glazing style! Place the glazed cookies back on the wire rack with parchment paper underneath to catch any drips.
12. Allow the glaze to set completely, which can take anywhere from 30 minutes to an hour, depending on the humidity in your kitchen and how thick your glaze is. Once set, your beautiful, zesty sugar cookies are ready to be devoured! Enjoy every single bite!
