📖 Instructions

1. Before you even touch the butter, make sure it’s softened. Leave 2 sticks (1 cup) of unsalted butter out at room temperature for about an hour or two, until it’s pliable but still cool to the touch. This is super important for a smooth, creamy dough.
2. In a large mixing bowl, preferably with an electric mixer, beat the softened unsalted butter and 1 1/2 cups of granulated sugar together. You want to beat this mixture on medium-high speed for about 3 to 5 minutes, until it becomes wonderfully pale yellow, light, and fluffy. Don't rush this step! Scrape down the sides of the bowl with a spatula a couple of times to ensure everything gets evenly combined.
3. Crack one large egg into a small bowl first (this ensures no shells end up in your dough!). Add the egg to the butter-sugar mixture and beat on medium speed until it’s just combined. Don't overmix. Then, pour in 2 teaspoons of pure vanilla extract. Beat briefly until the vanilla is fully incorporated and you can smell that lovely aroma.
4. In a separate medium bowl, whisk together 3 cups of all-purpose flour, 1 teaspoon of baking powder, and 1/2 teaspoon of salt. Make sure these dry ingredients are well combined. This prevents pockets of baking powder or salt in your final cookies.
5. Gradually add the dry ingredient mixture to the wet ingredients, a cup at a time, mixing on low speed after each addition. Mix only until the flour is just incorporated and the dough comes together. Overmixing at this stage will develop too much gluten, resulting in tough cookies. The dough will be soft, but it shouldn't be overly sticky.
6. Divide the dough in half. Flatten each half into a disk, wrap tightly in plastic wrap, and refrigerate for at least 1 hour. Chilling is crucial! This helps the butter firm up, preventing the cookies from spreading too much in the oven and ensuring they hold their cut shapes beautifully.
7. Once your dough is chilled and you're ready to bake, preheat your oven to 350°F (175°C). Line several baking sheets with parchment paper. This helps prevent sticking and makes for easy cleanup.
8. Lightly flour a clean work surface and your rolling pin. Take one disk of chilled dough from the fridge. Roll out the dough to about 1/4 inch thickness. For consistent results, you might even use rolling pin guides. This thickness gives you that perfect tender texture.
9. Using your favorite cookie cutters, cut out shapes from the rolled dough. Try to place the cutters as close together as possible to minimize scraps. Carefully transfer the cut-out cookies to your prepared baking sheets, leaving about 1 inch between each cookie. Re-roll any dough scraps together, chill for 10-15 minutes if it gets too warm, and then cut out more shapes.
10. Bake one sheet at a time in the preheated oven for 8 to 10 minutes, or until the edges are lightly golden. The centers should still look soft and slightly pale. Do not overbake! Overbaking is the enemy of tender sugar cookies.
11. Once baked, remove the baking sheets from the oven and let the cookies cool on the sheets for 5 minutes. This allows them to firm up slightly. Then, carefully transfer the cookies to a wire rack to cool completely. Let them cool down fully before you even think about decorating.
12. Now for the fun part! Once completely cool, decorate your cookies with royal icing, buttercream, sprinkles, or whatever your creative heart desires. They're delicious plain, too, but decorating them just adds that extra sparkle for any occasion.
