The almond flour is non-negotiable here—Bob’s Red Mill or Anthony’s are reliable brands. Erythritol can be found at Whole Foods or most health food stores, but check the label to ensure it’s pure (no fillers). For the vanilla, Nielsen-Massey or Rodelle offer the best pure extracts. Always use room temperature eggs—they incorporate better into the dry mix.

No erythritol? Monk fruit sweetener at a 1:1 ratio works well. Almond flour can be swapped for hazelnut flour if preferred, but avoid coconut flour—it absorbs moisture differently. If you’re out of xanthan gum, 1 tsp psyllium husk powder can substitute. The sliced almonds can be replaced with chopped pecans or walnuts for a different crunch.

Store biscotti in an airtight container at room temperature for up to 2 weeks. For longer storage, freeze for up to 3 months. The texture actually improves after a day, so don’t rush to eat them fresh out of the oven.

Step-by-Step Instructions for Sugar Free Biscotti

Follow this precise method to achieve perfectly crisp biscotti with rich almond and vanilla flavor.

Step 1: Prepare the Dry Ingredients

In a medium bowl, whisk together the 2 cups Almond Flour, 1 cup All-Purpose Flour, 1 tsp Baking Powder, 0.25 tsp Salt, and 0.25 tsp Xanthan Gum until fully combined. The xanthan gum is crucial here—it binds the gluten-free flours together, preventing crumbly biscotti.

I sift the all-purpose flour first to avoid lumps, which ensures even distribution in the batter. The mixture should look uniform with no visible streaks of individual ingredients. Set this aside while you prepare the wet ingredients.

Step 2: Cream Butter and Sweeteners

In a separate large bowl, beat the 0.25 cup Unsalted Butter (melted and cooled) with the 0.75 cup Erythritol using an electric mixer on medium speed for 2-3 minutes. The mixture should lighten slightly in color and become fluffy.

Erythritol doesn’t caramelize like sugar, but creaming it with butter incorporates air, which helps create the right texture. Add the 3 whole Large Eggs one at a time, mixing well after each addition, then stir in the 1 tbsp Vanilla Extract.

Step 3: Combine and Shape the Dough

Gradually add the dry ingredients to the wet mixture, folding gently with a spatula until just combined. Avoid overmixing—this can make the biscotti tough. Fold in the 0.5 cup Sliced Almonds until evenly distributed throughout the dough.

The dough will be thick and slightly sticky. Divide it in half and shape each portion into a 10-inch long log on a parchment-lined baking sheet. Flatten the tops slightly so they bake evenly. Chill the logs for 30 minutes to firm up before baking.

Step 4: Bake and Slice

Preheat the oven to 350°F. Bake the logs for 25-30 minutes until the edges are light golden brown and the centers are set. Remove from the oven and let cool for 10 minutes on the baking sheet.

Using a serrated knife, slice each log diagonally into ½-inch thick pieces. Lay the slices cut-side down on the baking sheet and return to the oven for 10-12 minutes, then flip and bake for another 10-12 minutes until crisp and deep golden brown.

Step 5: Cool Completely

Transfer the biscotti to a wire rack and let cool completely for at least 1 hour. They’ll continue to crisp up as they cool. The final texture should be hard and dry, perfect for dipping in coffee or tea.

Store in an airtight container at room temperature for up to 2 weeks. If they lose their crispness, revive them in a 300°F oven for 5-10 minutes before serving.

Flavor Customization for sugar free biscotti

Citrus Zest Twist

Add 1 tbsp lemon or orange zest to the dry ingredients for a bright, citrusy note. The oils in the zest release during baking, complementing the vanilla beautifully. I love how this small addition cuts through the richness of the almonds.

Spiced Warmth

Incorporate ½ tsp cinnamon or ¼ tsp cardamom with the dry ingredients for a warm, aromatic flavor. These spices pair wonderfully with the vanilla and add a cozy depth to each bite. 💛

Chocolate Drizzle

Melt ¼ cup sugar-free dark chocolate and drizzle over cooled biscotti for an elegant finish. I use Lily’s brand—it’s sweetened with stevia and erythritol, matching our sugar-free theme perfectly.

Nut Variations

Swap the sliced almonds for ½ cup chopped pistachios or pecans for a different texture and flavor. Pistachios add a lovely green speckle and a slightly sweet, earthy taste. Toast them first for extra crunch.

Coffee Infusion

Add 1 tsp instant espresso powder to the dry ingredients for a subtle coffee flavor that enhances the almond notes. This version is my favorite for dipping in a morning latte. ☕

Coconut Delight

Replace ¼ cup of the almond flour with unsweetened shredded coconut for a tropical twist. The coconut toasts slightly during baking, adding a delicate, nutty sweetness without sugar.
