Ingredients

For the Walnut Macarons:

  • 1 cup icing sugar, divided
  • 3/4 cup California walnuts, chopped extra fine
  • 2 large egg whites, at room temperature

For the Limoncello Buttercream:

  • 1/2 cup butter, softened
  • 1 cup icing sugar
  • 3-4 tablespoons limoncello
  • 1 lemon, zest

Preparation

For the Walnut Macaron:

  1. Preheat oven to 375°F.
  2. In a food processor, add 3/4 cup of icing sugar and walnuts and pulse. Set aside.
  3. With a stand mixer on medium speed, whisk egg whites until foamy. Reduce speed to low while adding remaining icing sugar (1/4 cup), then increase the speed to high, and whisk until stiff peaks form (approximately 8 minutes).
  4. Sift walnut mixture over egg whites, and gently fold until the mixture is smooth and shiny.
  5. If desired, for a variation of colors, divide macarons batter into three bowls and fold in 1 to 2 drops of food coloring into each bowl before piping and baking.
  6. Transfer the mixture to a pastry bag fitted with a 1/2-inch plain round tip, and pipe 3/4-inch rounds 1-inch apart on a parchment lined baking sheet. To flatten any peaks, dip your finger in water and gently press down on the macarons.
  7. Tap the bottom of each baking sheet to release any trapped air bubbles in the macarons. Let stand at room temperature for 15 minutes before baking.
  8. Place 1 baking sheet in oven at a time and turn oven down to 325°F. Bake for 12-15 minutes. After each batch, increase oven temperature to 375°F, for 5 minutes then reduce back to 325°F for the next batch. Continue until all macarons are baked. Let cool before removing from parchment.

For the Limoncello Buttercream:

  1. For the buttercream, combine butter, sugar, limoncello and lemon zest in a stand mixer and whip on medium-high speed until light and fluffy, about 10 minutes.
  2. Sandwich two similar sized macarons with 1 teaspoon of filling.
  3. Serve immediately or stack the macarons between layers of parchment in an airtight container and freeze for up to three months.
