Ingredients
  

Essential Ingredients
  • 2 sticks unsalted butter room temperature (225g)
  • ½ cup pistachio paste 60g, high-quality paste recommended
  • 2 cups powdered sugar sifted (250g)
  • ¼ teaspoon coarse kosher salt

Equipment

  • Stand mixer with paddle attachment
  • large mixing bowl
  • Silicone spatula
  • fine-mesh sieve

Method
 

  1. Ensure your butter reaches proper room temperature (2-3 hours outside refrigerator). Sift powdered sugar thoroughly to prevent lumps. Measure all ingredients precisely for consistent results.
  2. In mixing bowl with paddle attachment, combine softened butter and pistachio paste. Beat on medium-high speed for 2 minutes until mixture becomes pale and fluffy. Scrape bowl sides and bottom halfway through mixing.
  3. Add half the sifted powdered sugar to butter mixture. Mix on low speed until sugar incorporates completely to prevent sugar explosion.
  4. Add remaining powdered sugar and kosher salt. Start mixing on low speed, gradually increasing to medium-high. Continue beating until frosting is smooth and fluffy, about 2 more minutes.
  5. Check that finished pistachio cream butter is smooth, pipeable, and holds its shape. If too thick, add 1 tablespoon room-temperature milk. If too thin, gradually add more sifted powdered sugar.

Notes

Room temperature ingredients are crucial for smooth texture. Always use room-temperature liquids if thinning to prevent curdling. This buttercream can be made up to one week in advance and stored refrigerated. Flavor improves after 24 hours as ingredients meld together.
