Sugar Free Biscotti Recipe: Crunchy Almond and Vanilla Twice-Baked

This twice-baked treat delivers crunchy perfection without the sugar. I developed this method after years of testing to achieve that signature biscotti texture.

Almonds and vanilla create rich flavor, while the baking process ensures each slice stays dry and crisp. Perfect for dipping in coffee or enjoying as a light dessert.

Ingredients for Sugar Free Biscotti

Almond flour and erythritol replace traditional ingredients for a crisp, sugar-free biscotti experience.

The almond flour is critical here—Bob’s Red Mill offers a consistent, fine grind that’s ideal for baking. Erythritol can be found in the baking aisle of most Whole Foods or Kroger locations. Look for granulated varieties, as they mimic sugar’s texture best. Whole almonds should be fresh and raw; avoid pre-salted or roasted versions, which can affect the final flavor and texture.

If you’re out of almond flour, a blend of coconut flour and additional almonds can work, but texture will vary. Erythritol can be swapped for monk fruit sweetener at one-to-one ratio. For a nut-free version, substitute sunflower seeds for almonds and use oat flour instead of almond flour. The vanilla and almond extracts are key for depth—don’t skip them.

Store biscotti in an airtight container at room temperature for up to 2 weeks. For longer storage, freeze for 3 months. Re-crisp in the oven at 300°F for 10 minutes if they soften.

Step-by-Step Instructions for Sugar Free Biscotti

Master the twice-baked technique for perfectly crisp, flavorful biscotti every time.

Step 1: Prepare the Dry Ingredients and Nuts

Preheat your oven to 350°F and line a baking sheet with parchment paper. In a large bowl, whisk together the 2.5 cups Almond Flour, 0.75 cup Erythritol, 1 tsp Baking Powder, 0.25 tsp Sea Salt, 0.25 tsp Xanthan Gum, and 0.5 tsp Cinnamon until thoroughly combined. The xanthan gum acts as a binder, while the cinnamon adds subtle warmth to complement the almond.

Roughly chop the 1 cup Whole Almonds—I prefer pieces about the size of a pea for even distribution and satisfying crunch. Stir the chopped almonds into the dry mixture. This ensures every bite has a nutty texture without overpowering the delicate vanilla and almond flavors.

Step 2: Combine Wet Ingredients and Form the Dough

In a separate bowl, whisk together the 2 whole Large Eggs, 0.25 cup Unsalted Butter (melted and cooled), 2 tsp Pure Vanilla Extract, and 0.5 tsp Almond Extract. The almond extract enhances the natural flavor of the flour and nuts, creating a cohesive profile.

Pour the wet ingredients into the dry mixture and stir with a spatula until a thick, cohesive dough forms. It will be slightly sticky—that’s normal. If the dough feels too wet, let it rest for 2 minutes; the almond flour will absorb excess moisture. Resist the urge to add more flour, as this can make the biscotti dry.

Step 3: Shape and First Bake

Divide the dough in half and place each portion on the prepared baking sheet. Using lightly wet hands (to prevent sticking), shape each into a log approximately 12 inches long and 2 inches wide, flattening the tops slightly. Space the logs at least 3 inches apart to allow for spreading.

Bake on the center rack for 25-30 minutes until the logs are firm to the touch and the edges are just beginning to turn light golden brown. Rotate the baking sheet halfway through for even baking. The centers may still look slightly soft, but they’ll firm up as they cool.

Step 4: Slice and Second Bake

Remove the baking sheet from the oven and reduce the temperature to 300°F. Let the logs cool on the sheet for 10 minutes—this makes them easier to slice without crumbling. Using a sharp serrated knife, cut each log diagonally into ½-inch thick slices.

Place the slices cut-side down on the baking sheet, spacing them ½ inch apart. Return to the oven and bake for 15-20 minutes, flipping halfway through, until both sides are deep golden brown and completely dry to the touch. This second bake is what gives biscotti its signature crispness.

Step 5: Cool Completely and Store

Transfer the biscotti to a wire rack and let them cool completely, about 1 hour. They’ll continue to crisp as they cool. Once at room temperature, store in an airtight container at room temperature for up to 2 weeks.

The texture should be firm enough to dip into coffee or tea without breaking, yet tender enough to bite into cleanly. For best results, wait at least 24 hours before serving—this allows the flavors to fully develop and the texture to perfect.

Serving Suggestions for This Dish

Coffee Pairings

These biscotti were born to be dunked in coffee. I love them with a bold espresso or dark roast—the bitterness contrasts beautifully with the sweet vanilla notes. David swears by Central Market’s Italian roast for this exact purpose.

Tea Time

A strong Earl Grey or chai tea works wonderfully too. The bergamot in Earl Grey enhances the almond flavor, while chai’s warmth complements the cinnamon. I always keep a tin of Bigelow on hand for this.

Dessert Platter

Arrange biscotti on a wooden board with sugar-free dark chocolate and fresh berries. The chocolate’s richness pairs perfectly with the nutty crunch. I often add raspberries for a pop of color and tartness.

Gift Presentation

Stack cooled biscotti in cellophane bags tied with twine for a thoughtful homemade gift. Add a handwritten tag with dipping instructions. These keep well for 2 weeks at room temperature, making them perfect for sharing. 💛

Breakfast Boost

Serve with Greek yogurt and a drizzle of sugar-free caramel syrup for a protein-packed breakfast. The biscotti’s crunch contrasts nicely with the creamy yogurt. Emma loves this combo before school.

Wine Pairing

For an elegant touch, pair with a glass of Vin Santo or Moscato d’Asti. The sweetness of these Italian wines complements the biscotti’s nutty flavors without overpowering them.
