How to Make Shamrock Sugar Cookies | Decorated St Patrick’s Day Cookies

Whisk Dry Ingredients: In a medium bowl, whisk together 2 and 1/4 cups all-purpose flour, 1/2 teaspoon baking powder, and 1/4 teaspoon salt. This mixture is the foundation of your cookies, ensuring they rise just right while keeping the texture tender.

Cream Butter and Sugar: In a large bowl, using a stand mixer fitted with a paddle attachment, beat 3/4 cup unsalted butter and 3/4 cup granulated sugar on high speed for about 3 minutes. The goal is for the mixture to become fluffy and pale. Next, add the seeds scraped from 1 whole vanilla bean and continue beating until well incorporated and creamy. This not only enhances flavor but creates an airy texture.

Incorporate Egg and Vanilla: Add 1 large egg (at room temperature) and 2 teaspoons pure vanilla extract to the mixture. Beat on high speed for about 1 minute until combined, scraping down the bowl’s sides as needed. Ensuring all ingredients are well mixed is crucial for uniform cookies.

Combine Dry and Wet Ingredients: Slowly add the dry mixture to the wet ingredients, beating on low speed just until combined. The dough might be a bit soft; if it feels excessively sticky, add an extra tablespoon of flour to help with rolling.

Chill the Dough: Divide the dough into two equal portions. Place each piece onto a lightly floured parchment paper or silicone baking mat. Roll both portions into 1/4-inch thickness using a lightly floured rolling pin. Dust one piece lightly with flour, place parchment over it, then stack the second rolled dough on top. Cover with plastic wrap and refrigerate for at least 1-2 hours or up to 2 days.

Preheat and Prepare to Bake: When ready to bake, preheat your oven to 350°F (177°C). Line 2-3 baking sheets with parchment paper or silicone mats. Remove the top piece of dough from the fridge, carefully peel it off the parchment, and cut into desired shapes using a cookie cutter; shamrock shapes are obviously perfect for St. Patrick’s Day! Continue to cut and re-roll until all dough is used.

Bake the Cookies: Arrange your cut cookies on the prepared baking sheets about 3 inches apart. Bake for 11-12 minutes, until lightly golden around the edges. Keep an eye on them, and if your oven has hot spots, rotate the sheets halfway through baking to ensure even cooking. After baking, let the cookies cool on the sheets for about 5 minutes before transferring them to a wire rack to cool completely.

Make the Frosting: In a deep bowl, beat 3/4 cup unsalted butter and the seeds from 1/2 a vanilla bean on medium speed until creamy, approximately 2 minutes. Gradually add the 3 cups of sifted confectioners’ sugar, 3 tablespoons of heavy cream, and 1 and 1/2 teaspoons pure vanilla extract. Start slowly, then ramp up to medium-high speed, mixing for about 2 minutes until the frosting is fluffy and smooth. Taste, and if it’s overly sweet, add a pinch of salt to balance.

Decorate: You can divide the frosting and tint it with gel food coloring if you’re feeling festive! Use a knife, icing spatula, or a piping bag to decorate your cookies—get creative! I love piping hearts for the leaves of the shamrock and a thin line for the stem. Adding sprinkles can elevate the fun factor, making these cookies extra special.

Storing & Reheating

To store your cookies, keep them covered at room temperature for up to one day if they’re frosted. If you need to store them longer, place them in the refrigerator for up to one week. Unfrosted cookies can be stored covered at room temperature for up to 5 days or in the refrigerator for up to a week. For longer storage, freeze them in an airtight container or a freezer-safe bag for up to three months. To refresh, allow them to thaw at room temperature and enjoy the soft, delicious texture.

Chef’s Helpful Tips

Use room-temperature eggs and softened butter for the best texture when mixing.
If your dough is too sticky while rolling, keep adding a little flour until it reaches a manageable consistency, but be careful not to overdo it!
When baking cookies, place them evenly on the baking sheet, giving them plenty of space for the heat to circulate.
Experiment with frosting and colors; don’t hesitate to mix and match for a personalized touch.
These cookies can also be frozen before baking, simply place the cut-out shapes on a baking sheet, freeze until solid, then transfer to a zip-top bag until ready to bake.
