Ingredients

  • CRUST
  • 1 1/2 cups flour
  • 1/4 cup sugar
  • 9 tablespoons butter
  • 2 tablespoons chilled whipping cream (or more)
  • 1 1/2 teaspoons vanilla extract
  • FILLING
  • 3/4 cup whole almond, toasted
  • 3/4 cup pecans, toasted
  • 3/4 cup walnuts, toasted
  • 3/4 cup light corn syrup
  • 1/4 cup packed golden brown sugar
  • 1/4 cup butter, melted
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup semi-sweet chocolate chips

Method

  • FOR CRUST: Combine flour and sugar in a food processor.
  • Add butter and cut in, using on/off turns, until mixture resembles coarse meal.
  • Add 2 tablespoons cream and vanilla extract.
  • Using on/off turns, blend until moist clumps form, adding more cream by tablespoonful if dough is dry.
  • Gather dough together.
  • Press dough over bottom and up the sides of an 11-inch diameter tart pan with removable bottom.
  • (I used a 9-inch pan with very little crust and filling left over.) (Dough can be made 1 day ahead. Cover and chill, but let stand at room temperature 30 minutes before filling.) FOR FILLING: Preheat oven to 350 degrees.
  • Combine all toasted nuts in a food processor; chop coarsely, using on/off turns.
  • Whisk corn syrup, brown sugar, and melted butter in a large bowl to blend.
  • Whisk in eggs and vanilla extract.
  • Mix in chocolate chips, then nuts.
  • Transfer filing to the prepared crust.
  • Bake tart until firmly set in center and top is deep golden brown, about 50 minutes.
  • Cool tart in pan on rack 30 minutes.
  • Push up pan bottom to release tart.
  • Serve warm or at room temperature.
