Tips/Tricks
Start with high-quality, unsalted pistachios—chop them finely for even distribution, or toast them first to boost flavor. If you can’t find pistachio butter, it’s easy to make your own by blending toasted pistachios until smooth. Always use room temperature butter to help the dough mix evenly and avoid overworking it, which can make the cookies crumbly. Shape the dough into a smooth, compact log for uniform cookies, and chill it thoroughly before slicing; if it’s too firm, let it rest a few minutes at room temp. The dough stores beautifully—refrigerate for up to 3 days or freeze for 3 months—so you can bake whenever you’re ready.

Variations
For mini cookies, divide the dough into smaller balls and shorten the bake time by about 5 minutes—just bake until the edges turn golden. If you’re going for a fun confetti version, use large bar-shaped sprinkles in the dough instead of nonpareils, which tend to bleed and discolor the batter.
