Make This Recipe


Blackberry Filling:

  • 6 ounces fresh or frozen (thawed) blackberries, partially mashed
  • 1/2 cups sugar
  • 1 1/2 tablespoons cornstarch


  • Nonstick cooking spray
  • 1 cup very finely chopped pecans
  • 3/4 cup all-purpose flour
  • 1/2 teaspoon ground cardamom
  • 1/3 cup sugar
  • 1/2 teaspoon vanilla
  • 1/2 cup unsalted butter, softened well

Mascarpone Lemon Filling:

  • 4 ounces mascarpone cheese
  • 1 1/4 cup sugar
  • 3 tablespoons flour
  • 3 Eggland’s Best eggs, large
  • 1 1/2 teaspoons lemon zest
  • 1/2 cup strained fresh lemon juice


  • 3 tablespoons finely chopped fresh basil
  • 4 tablespoons coarse white sugar


  1. Blackberry Filling: Cook blackberries in a medium saucepan over medium heat, until juicy and beginning to get syrupy about 5 minutes. Remove from heat. In a bowl or cup, mix the sugar and cornstarch. Sprinkle into the blackberries and mix well. Return to heat and bring back to a gentle boil, stirring constantly. Cook another 2 minutes, stirring, or until very thick and no longer opaque.
  2. Crust: Heat oven to 350°F. Prepare an 8-inch square pan with non-stick spray and line with foil across the bottom and up each side, letting it slightly hang over the sides. Mix the chopped pecans, flour, cardamom, and sugar in a bowl. Add vanilla and softened butter; mix until crumbly. Press evenly in bottom of pan. Bake 25 minutes, or lightly browned on edges.
  3. Mascarpone Lemon Filling: While crust is baking, make filling by mixing mascarpone cheese, sugar, flour, and Eggland’s Best eggs, until smooth. whisk in lemon zest and juice.
  4. When the crust is browned on the edges, pull the oven rack out and pour the lemon mixture over the hot crust. Spoon the blackberry mixture into the filling in separate mounds, then lightly swirl with a spoon. Bake another 30-35 minutes, or until filling is starting to puff and doesn’t jiggle in the middle when moved/shaken.
  5. Cool completely in the pan, then remove with the foil liner.
  6. Before serving, muddle the basil and coarse sugar together and sprinkle over the top of the bars. Cut to the desired size for serving.
