‍ Step-by-Step Instructions

✅ 1. Make the Pistachio Cake Base

  1. Preheat oven to 350°F (175°C). Line a baking sheet or cake pan with parchment.
  2. In a bowl, mix ground pistachios, flour, salt, and baking powder.
  3. In another bowl, beat eggs and sugar until light and fluffy (about 3 minutes).
  4. Add melted butter, milk, and vanilla to the egg mixture. Stir until combined.
  5. Fold in the dry ingredients.
  6. Pour batter into prepared pan and bake for 15–20 minutes, or until a toothpick comes out clean.
  7. Let cool completely, then cut into rounds using a cookie cutter or ring mold to fit your mousse molds.

✅ 2. Prepare the Meyer Lemon Curd

  1. In a saucepan, whisk lemon juice, zest, sugar, and egg yolks.
  2. Cook over medium-low heat, stirring constantly, until thickened (about 8–10 minutes).
  3. Remove from heat, whisk in butter until smooth.
  4. Let cool completely, then strain for a silky texture.

✅ 3. Make the Mousse

  1. Sprinkle gelatin over cold water in a small bowl. Let bloom for 5 minutes.
  2. Gently heat gelatin until dissolved and stir into the cooled lemon curd.
  3. Fold in whipped cream in two additions until fully combined and smooth.

✅ 4. Assemble the Cakes

  1. Place pistachio cake rounds into silicone molds or dessert rings.
  2. Spoon or pipe lemon mousse over each cake base, smoothing the tops.
  3. Chill for at least 4 hours or overnight to set.

✅ 5. Garnish & Serve

  1. Carefully unmold the mousse cakes.
  2. Garnish with crushed pistachios, candied lemon peel, or mint.
  3. Serve chilled for best texture and flavor.

️ Tips for Success

  • Use Meyer lemons for their sweeter, floral citrus notes. Regular lemons work too, though they’ll be slightly more tart.
  • For a deeper pistachio flavor, toast the nuts before grinding.
  • Don’t skip the gelatin—it helps the mousse set to the perfect consistency.
  • Use silicone molds for easy release and elegant presentation.

Storage & Make-Ahead

  • Store in the refrigerator for up to 3 days.
  • These cakes are ideal for making a day in advance.
  • Not freezer-friendly due to the mousse texture.
