  • Biscotti
  • cups all-purpose flour
  • 1 teaspoon baking powder
  • ½ teaspoon salt
  • 2 large eggs at room temp
  • 1 cup plus 3 Tablespoons sugar
  • ¼ cup extra light olive oil or a mild flavored oil
  • peeled zest of 3 large lemons finely chopped
  • ½ cup milk I used unsweetened almond milk
  • Lemon Glaze
  • 1 cup powdered confectioner's sugar
  • 2 Tablespoons freshly squeezed lemon juice


  • Preheat the oven to 350F. Line two baking sheets with parchment paper.
  • Combine the flour, baking powder, and salt in a medium bowl and mix together thoroughly.
  • In a large bowl with an electric mixer, beat the eggs and sugar for 3-4 minutes, until thick and pale. Gradually beat in the oil and the lemon zest.
  • Add the flour mixture, alternately with the milk, beginning and ending with the flour.
  • Scrape out the dough with a rubber spatula onto a clean counter. Spray hands with cooking spray (or rub on some olive oil)and divide the dough into 2 equal pieces. Shape each portion into a flattened logs that are about 3.5 inches wide.
  • Place the first logs one of the prepared baking sheets (if you’re using 1 baking sheet, space the logs out about 2-inches apart, they will expand a little while baking). Score the biscotti logs with a very sharp knife about 1/2-inch apart (this will help to slice them when they’re totally cooled down to prep for the second part of baking).
  • Bake until they are golden and firm, about 25 minutes, turning the tray halfway halfway through baking time. Cool on the sheet on a wire rack for 10 minutes.
  • Transfer sheet to a wire rack and let logs cool completely (could take a full 30 minutes). Reduce oven temperature to 325F degrees.
  • Transfer the first loaf carefully to a cutting board. When the logs have completely cooled down, begin slicing the first biscotti log approximately 1/2 inch apart by pressing a very sharp knife straight down into the dough (if you scored the dough, you’ll be slicing where you marked with the knife before baking).
  • Place the cookies back on the baking sheet, cut sides up. Keep in mind that the when you slice on a bigger angle, you will get much longer cookies. If you slice short angles, you’ll get small biscotti.
  • Place the second log on the cutting board and repeat process cutting out the cookie pieces and placing on the baking sheet. It should yield approximately 35-37 biscotti.
  • Bake 7 minutes, flip biscotti, and bake 7 minutes more (it may only take 5 minutes on each side, every oven is different). Let cool completely (they will also dry out a bit more) on wire rack. Enjoy!
  • For the Glaze
  • In a small bowl, stir together the lemon juice with the powdered sugar. It should become a thick and pourable glaze (if it’s too thick, add bit more lemon juice one teaspoon at a time. If it’s too confectioner’s sugar a tablespoon at a time).
  • Drizzle on the glaze and let it completely cool down. You could place the glaze in a zipped lock bag. Close the bag and cut a tiny triangle off a bottom corner of the bag. Gently squeeze the bag to add the glaze to the biscotti.


  • Can make this with a stand or hand mixer. You could even make the whole thing by hand using a wooden spoon to mix it (will take a little arm power).
  • The lemon glaze is tart. You could sub some of the lemon juice with milk (almond milk if you’re dairy free), or omit the glaze all together.
  • Yields: 35-37 biscotti. Depending on how you slice them, but mostly depends on how large you make the biscotti logs. 
  • Baking time could vary (again, depending on how big or small you slice them)so keep an eye on them when you're baking the sliced biscotti. It could take 5 minutes per side or up to 10 minutes per side to crunch up and get nice golden color).
