Ingredients

For the Meringue Cookies

  • 6 egg whites
  • 1/2 teaspoon cream of tartar
  • 2/3 cup sugar
  • 1 cup roasted unsalted cashews
  • 1/4 cup flour
  • 1 teaspoon vanilla extract

For the French Buttercream

  • 1/2 cup sugar
  • 3 tablespoons water
  • 5 egg yolks
  • 8 ounces (2 sticks) butter, softened and at room temperature

For Assembling Silvanas

  • 2 cups roasted unsalted cashews
  • 1 cup graham cracker crumbs

Instructions

For the Meringue Cookies

  • In a food processor, blend together all-purpose flour and 1 cup cashews until fine. Set aside.
  • Preheat oven to 325 F. 
  • Line a cookie sheet with parchment paper. Using a marker, trace several circles about 2.5 inches diameter on the parchment with about 1 1/2 inches of space in between.
  • In the bowl of a stand mixer, beat the egg whites on medium-high speed until foamy. 
  • Sprinkle in cream of tartar and continue to beat until soft peaks form.
  • Gradually add sugar and continue to beat until stiff peaks form. 
  • Using a rubber spatula, gently fold in the vanilla and the ground cashews/flour mixture in three additions.
  • Transfer the meringue into a large piping bag fitted with a large piping tip. Following the circles as a guide, pipe circles that are about 1/2 inch high on the parchment paper. 
  • Using a small knife or an offset spatula, smoothen and flatten tops of the meringue. Gently tap the baking sheet on the counter to remove any bubbles.
  • Bake the meringue in a 325 F oven for about 18 to 20 minutes, or until lightly golden. The edges will be tender-crisp and the middles are soft. 
  • Using a spatula, carefully transfer cookies to a cooling rack and let cool completely.

For the French Buttercream

  • In a medium saucepan, combine sugar and water and stir. Cook the mixture over medium heat. Once boiling, place a candy thermometer in the pan to monitor the temperature.
  • Meanwhile, start to beat the egg yolks on a stand mixer on high speed until thickened and pale in color. 
  • Continue to beat yolks until the water and sugar mixture on the stove registers 238 F. Turn the heat off and slowly pour the sugar syrup in a thin, continuous stream into the yolks with the mixer running.
  • Continue to beat the yolk mixture until the mixing bowl is cool to the touch. 
  • With the mixer still running, add the softened butter, about a tablespoon at a time, and beat until a fluffy buttercream forms.

Assembling the Silvanas

  • In a food processor, process the 2 cups of cashews until resembles fine crumbs.
  • Spread a thin layer of buttercream on the rough side of a cookie ( the side that was facing up during baking). Top it with another meringue cookie with the rough side against the buttercream. 
  • Spread more buttercream on the sides and the base of cookies to completely cover. 
  • Roll the buttercream-covered cookie sandwiches in ground cashews. Roll the other cookies in graham cracker crumbs.
  • On a parchment-lined baking sheet, arrange silvanas in a single and freeze for about 1 to 2 hours or until firm.
  • For longer storage, transfer the cookies into an airtight container and keep frozen until ready to serve.
