Servings 12 large biscotti


  • For the dough:
  • 2 eggs
  • ½ cup sugar
  • 3 ounces oil
  • 2⅓ cup all-purpose flour
  • tbsp baking powder
  • 1 apple core removed and coarsely grated
  • ½ tsp nutmeg
  • ¼ tsp cinnamon (optional)
  • tsp cloves (optional)
  • zest of 1 orange
  • For the filling:
  • ½ cup fresh chopped walnuts
  • ½ cup orange marmalade
  • ¼ tsp cinnamon (optional)
  • For the glaze:
  • About 2 cups confectionary sugar
  • Juice of ½ orange


Prepare parchment paper:

  • Line 10"x15" baking pan with parchment paper. Set aside.
  • Prepare another sheet of parchment paper by cutting it lengthwise to have two halves. Sprinkle each half parchment paper with a little flour. Set aside.

Make the dough:

  • Preheat oven to 350°F for first bake.
  • Place eggs in mixer bowl and beat for few minutes.
  • Slowly add sugar and beat for for 2 to 3 more minutes or until mixture is creamy and fluffy.
  • Then slowly add oil to combine.
  • In a separate bowl, combine flour with baking powder.
  • Sift flour mixture into egg mixture. Stir with wooden spoon to incorporate. The batter will be stiff.
  • Add grated apple, orange zest, and nutmeg (and cinnamon/cloves, if using) to mixture. Stir until just combined.

Prepare the filling:

  • In small bowl, stir walnuts and marmalade (with cinnamon, if using). Set aside.

Assemble the loaf:

  • Divide dough in half. For each dough, sprinkle a little flour on top and use hands to gently flatten and shape into rectangle about 8” X 5”.
  • On one dough, spread walnut mixture, leaving only about ¼” margin. Brush a little water on margin.
  • Carefully lift and flip other half over it, using parchment paper to guide it.
  • Use hands to flatten slightly, sealing edges by lightly pressing together. Keep the rectangular shape.
  • Bake for about 25 - 30 minutes or until lightly golden and inserted toothpick comes out clean.
  • Remove from oven and place on wire rack to cool slightly. Reduce oven to 300.
  • Remove loaf from the pan, keeping it on parchment paper. Using large serrated large knife, cut firmly into 1” slices.
  • Place sliced loaf back on baking pan, keeping parchment paper. Arrange slices to spread out. Bake again for about 20 minutes or until desired texture is reached.
  • Remove from oven and let cool.

Glaze the biscotti

  • Whisk together icing sugar, orange juice, and nutmeg. You may need to add more orange juice (or water) or icing sugar to reach a smooth and creamy texture. The glaze should be pourable but thickened.
  • When the biscotti are completely cooled, re-form the slices into the loaf, keeping them tightly together. Use pastry brush to paint top surfaces and sides with glaze. Allow slices to dry for about 15 minutes.
  • Then use knife to re-cut the slices to separate them. Let the icing cool completely.
  • Store in air-tight container. The biscotti freeze beautifully before glazing.



For a smaller biscotto, shape each half of dough to measure 4"X10". The batter will spread.

Consider adding other warming spices like cinnamon to the batter and/or glaze.
Replace the orange with lemon if you prefer.
