# Directions:

02 - Whisk flour, pistachios, baking powder, baking soda, and salt in a medium bowl until evenly distributed.
03 - Rub lemon zest into sugar in a large bowl to release essential oils. Whisk in oil, eggs, and vanilla until smooth.
04 - Stir milk and lemon juice into the wet mixture until fully combined.
05 - Gently fold dry ingredients into wet mixture until just incorporated. Avoid overmixing to prevent tough texture.
06 - Pour batter into prepared pan, smooth top, and bake 30–35 minutes until toothpick inserted in center comes out clean.
07 - Let cake rest in pan for 10 minutes, then transfer to wire rack to cool completely before frosting.

09 - Spread frosting evenly over cooled cake. Garnish with chopped pistachios and lemon zest.

# Expert Tips:

01 -
  • The texture is incredible, moist and tender with tiny crunches of pistachio throughout
  • Mascarpone frosting is less sweet than traditional buttercream, letting the lemon shine
  • It looks stunning with minimal effort, the green pistachios and yellow zest doing all the decorating work
02 -
  • Overwhipping the mascarpone frosting can cause it to curdle and separate, so stop as soon as it holds its shape
  • The cake must be completely cool before frosting, otherwise the mascarpone will melt and slide right off
  • Fresh lemon juice really matters here, bottled juice lacks the bright aromatic complexity this cake needs
03 -
  • Toast your pistachios lightly before chopping them to deepen their nutty flavor
  • Add a tablespoon of limoncello to the frosting for an adult twist that friends will love
