📖 Instructions

1. **For the Cookies:**
2. **Step 1: Cream Butter and Sugars.** In a large mixing bowl, using an electric mixer, cream together the softened unsalted butter, granulated sugar, and powdered sugar until the mixture is light, fluffy, and pale in color. This usually takes about 3-5 minutes. Don't skimp on this step! It incorporates air, which leads to tender cookies.
3. **Step 2: Add Wet Ingredients.** Beat in the large egg and pure vanilla extract until just combined. Be careful not to overmix here. Scrape down the sides of the bowl with a spatula to ensure everything is incorporated.
4. **Step 3: Combine Dry Ingredients.** In a separate medium bowl, whisk together the all-purpose flour, baking powder, and fine sea salt. Whisking ensures these ingredients are evenly distributed, preventing pockets of salt or leavener.
5. **Step 4: Gradually Add Dry to Wet.** With the mixer on low speed, gradually add the dry ingredient mixture to the wet ingredients, mixing until just combined. As soon as no streaks of flour are visible, stop mixing. Overmixing develops too much gluten, which can make your cookies tough.
6. **Step 5: Chill the Dough (Crucial Step!).** Divide the dough into two equal portions and flatten each into a disc. Wrap each disc tightly in plastic wrap. Refrigerate for at least 1-2 hours, or even overnight. Chilling is absolutely essential! It prevents the cookies from spreading too much and helps them hold their shape, giving you those crisp edges we want for the 'French tip' look.
7. **Step 6: Prepare to Roll.** When ready to bake, preheat your oven to 375°F (190°C). Line two baking sheets with parchment paper or silicone baking mats. Lightly flour your work surface and your rolling pin. Take one disc of chilled dough out of the fridge (keep the other one chilled).
8. **Step 7: Roll and Cut.** Roll the dough to about 1/4 inch thick. For uniform cookies, try to keep the thickness consistent across the entire sheet. Use your favorite Christmas-themed cookie cutters to cut out shapes. Carefully transfer the cut-out cookies to the prepared baking sheets, leaving about 1 inch between each cookie. Re-roll any scraps, but avoid overworking the dough.
9. **Step 8: Bake.** Bake for 8-10 minutes, or until the edges are very lightly golden. The centers should still be soft and pale. Overbaking will result in dry cookies. Remove from oven and let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. They must be completely cool before icing!
10. **For the Glossy Royal Icing:**
11. **Step 9: Mix Icing Base.** In a large bowl, whisk together the powdered sugar and meringue powder until well combined. Gradually add 3 tablespoons of warm water, whisking constantly until smooth. Add the pure vanilla extract. At this point, the icing should be quite thick, like toothpaste.
12. **Step 10: Achieve Flood Consistency.** Slowly add more warm water, 1/2 teaspoon at a time, mixing thoroughly after each addition, until the icing reaches 'flood consistency'. To test, lift your whisk and let the icing drizzle back into the bowl. It should sink back into itself and become smooth within 5-10 seconds. This is key for that glossy, even finish!
13. **Step 11: Color the Icing.** Divide about 1/4 of the prepared icing into separate small bowls. Tint these portions with gel food coloring of your choice for the 'tips' (e.g., red, green, gold). Keep the remaining large portion of white icing untinted. Cover all icing bowls with a damp cloth or plastic wrap directly on the surface to prevent crusting.
14. **Step 12: French Tip Decorating!** Transfer the white icing into a piping bag fitted with a small round tip (like PME #1 or Wilton #2). Outline the entire cookie and then flood the entire surface with the white icing. Use a scribe tool or toothpick to gently spread the icing and pop any air bubbles. Let this white base layer dry completely for at least 4-6 hours, or ideally overnight. This is vital for a clean 'French tip' look.
15. **Step 13: Add the Tips.** Once the white base is bone dry, transfer your colored icing(s) into separate piping bags, each fitted with a very small round tip. Carefully pipe a thin line or fill in just the 'tip' area of each cookie, following the natural curve or shape. You can add sprinkles or edible glitter to the wet colored icing for extra sparkle! Allow the colored tips to dry completely before stacking or packaging.
16. **Step 14: Storage.** Store fully decorated and dried cookies in an airtight container at room temperature for up to 2 weeks, or freeze for longer enjoyment. Just be sure they are *completely* dry before storing to prevent smudging.
