  • Chill Before Cutting: Roll out the dough before chilling it—trust me, it makes all the difference. Once chilled, use a shamrock cookie cutter to shape your cookies.

Notes

  1. Freezing Instructions: Plain or frosted cookies freeze well for up to 3 months. Thaw in the refrigerator or at room temperature. You can also freeze the dough for up to 3 months before rolling it out.
  2. Room Temperature Ingredients: Ensure butter and eggs are at room temperature for best results.
  3. Vanilla Bean Substitute: Use 1 teaspoon of vanilla bean paste instead of scraping seeds from a whole vanilla bean. Alternatively, increase pure vanilla extract to 2½ teaspoons if needed.
  4. Chilling Trick: Roll the dough out before chilling to prevent over-spreading during baking.
