📖 Instructions

1. Before you begin, get everything ready! Make sure your butter is softened to room temperature—this helps it cream beautifully. Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. This will prevent sticking and make cleanup a breeze.
2. In a medium bowl, take your dry ingredients: whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, and 1/4 teaspoon of salt. Give it a good whisk to ensure everything is evenly distributed. Set this bowl aside for a moment.
3. In a separate, larger mixing bowl, using an electric mixer (either a stand mixer with the paddle attachment or a hand mixer), beat 1 cup (two sticks) of softened unsalted butter on medium speed until it’s light and fluffy. This usually takes about 1-2 minutes.
4. Gradually add 1 cup of granulated sugar to the creamed butter, continuing to beat on medium speed for another 2-3 minutes until the mixture is truly light, pale, and fluffy. This step is super important for cookie texture, so don't rush it!
5. Crack one large egg into a small bowl first to ensure there are no shell bits, then add it to the butter-sugar mixture. Beat until just combined. Next, mix in 1 teaspoon of vanilla extract, 1 tablespoon of lemon zest, 1 tablespoon of orange zest, and 2 tablespoons of freshly squeezed lemon juice. Mix until everything is well incorporated.
6. With the mixer on low speed, slowly add the dry flour mixture to the wet ingredients, a little at a time. Mix *just* until the flour disappears and a soft dough forms. Be careful not to overmix, as this can make your cookies tough. Once it comes together, stop the mixer.
7. Using a small cookie scoop (about 1.5 tablespoons) or by hand, roll the dough into uniform balls. Place them about 2 inches apart on your prepared baking sheets. Don't press them down; they'll spread slightly as they bake.
8. Bake one sheet at a time in your preheated oven for 10-12 minutes, or until the edges are lightly golden and the centers look set but still soft. If you bake them too long, they might lose some of their tenderness. My personal preference? I pull 'em out right at 11 minutes for that perfect chew!
9. Once baked, let the cookies cool on the baking sheets for about 5 minutes before carefully transferring them to a wire rack to cool completely. This prevents them from breaking and helps them firm up.
10. While the cookies cool, prepare the glossy glaze! In a small bowl, whisk together 1.5 cups of powdered sugar with 3-4 tablespoons of freshly squeezed lemon juice. If you like, add 1-2 tablespoons of orange juice for an extra citrus boost. Keep whisking until the glaze is smooth, shiny, and lump-free. It should be thick enough to coat a spoon but still pourable.
11. Once the cookies are completely cool, spoon the glossy glaze over the top of each cookie. You can spread it gently with the back of a spoon for full coverage, or drizzle it for a more rustic look. Let the glazed cookies sit on the wire rack for about 15-20 minutes, or until the glaze has set and hardened slightly. Then, dig in and enjoy your little pieces of sunshine!
