You’ll need:

  • sugar. basic granulated white sugar for this recipe!
  • eggs.
  • gluten-free flour. This recipe works well with cup for cup/ 1:1 gluten-free flour blends.  I use King Arthur gluten-free for all my recipes using all-purpose flour.  If you use a different gluten-free flour blend with success, please comment and let me know!
  • cocoa powder. Be sure that your cocoa powder is labeled gluten-free.  Cocoa is an ingredient I often see warnings for being processed on shared equipment with wheat.  I use Anthony’s cocoa because not only is it delicious but it’s certified gluten-free and totally affordable.  You can find it on Amazon here.
  • Baking soda.  Not baking powder. Use baking soda.
  • Chocolate chips.  I like Hershey’s chocolate chips and Enjoy Life chocolate chips.  Enjoy life is a great option if you want dairy-free, you can buy them on Amazon here!
  • Hazelnuts.  Unfortunately, nuts are one of those ingredients that are so often come into cross-contact with wheat during processing.  Be sure to read labels to ensure that your nuts do not have an allergen warning for wheat or gluten.  The brand Daily Nuts and Fruits does have certified gluten-free nuts that are not cross-contacted with gluten.  You can find their hazelnuts on Amazon here.

Do you want a gluten-free sugar-free biscotti?

Simply sub your favorite sweetener for the sugar.  When subbing sweeteners in your cooking, even if the package claims a 1:1 substitute, start with less sweetener and adjust to taste.  You can always add more, but you can’t take it out once it’s in there.

I often err on the side of ‘less sweet.’  Adding too much sweetener can result in a baked good that’s bitter or gives a cooling effect.

My favorite sweetener for baking is Swerve.  Swerve is certified gluten-free and tastes great! You can find Swerve on Amazon here.

Do you want dairy-free biscotti?

Simply use dairy-free chocolate chips such as Enjoy Life!  You can buy them on Amazon here!

Double Chocolate Biscotti:

If you want to make a super-chocolatey double chocolate biscotti, replace the hazelnuts in this recipe with extra chocolate chips.  For a really pretty result, try white chocolate chips!

Chocolate almond biscotti:

To make chocolate almond biscotti, simply replace the hazelnuts with sliced almonds and your recipe will still taste delicious! I like Fisher’s sliced almonds and they’re gluten-free.

How to make gluten-free chocolate hazelnut biscotti:

First, you’ll need to preheat the oven to 350.

wet ingredients for biscotti in stand mixer

Whisk egg and sugar together in a mixing bowl thoroughly–until it’s pale yellow.

dry ingredients mixed cocoa flour baking soda sugar

Then, sift flour, cocoa powder and baking soda together.

I know sifting is a pain, but this really will make your recipe turn out much better!  A crank sifter like this one makes this so much easier.

Using a spatula, stir dry ingredients into egg mixture until well combined.

note: the dough will be VERY stiff.  You can use a stand mixer here if you’d like.

stirring in chocolate chips and hazelnuts into biscotti mixture

Next, add chocolate chips and nuts.

On a cookie sheet lined with parchment, scoop out dough and give the dough a rectangular shape about 12 inches long and 4 inches wide with spatula and bake in oven for 30 minutes.

note: If it is not forming into shape well, feel free to add 1 more tablespoon of water to the mix

Pull it out of the oven and reduce the oven’s temperature to 300.

Allow the biscotti to cool completely.

Then, slice the biscotti dough at a slight angle into 12 pieces (each piece should be about 1.5 inches wide) and separate on your parchment-lined cookie sheet cut side down.

Wait….why does my biscotti crumble when cutting it?
Most likely your biscotti is crumbling because it has not cooled enough.  The other reason could be the knife you are using.  A bread knife like this one is the most effective! 

Place back into the oven and continue baking for 10-12 minutes.
