Almond flour:

Almond flour is a gluten-free flour that is made by grinding blanched almonds into a fine powder.

It is high in protein and healthy fats, making it a nutritious alternative to wheat flour. Almond flour is used in this recipe to add richness and moisture to the biscotti.

Flaxseed meal:

Flaxseed meal is made by grinding flaxseeds into a fine powder.

It is high in fiber and omega-3 fatty acids, making it a nutritious addition to baked goods.

Flaxseed meal is used in this recipe as an egg substitute and to add texture to the biscotti.

Coconut sugar:

Coconut sugar is a natural sweetener that is made from the sap of coconut palm trees.

It has a lower glycemic index than regular sugar, meaning it causes less of a spike in blood sugar levels.

Coconut sugar is used in this recipe as a healthier alternative to regular sugar.

Step One: Make Oat Flour in a Blender or Food Processor

You can simply make oat flour at home with a blender or food processor.

If you have oat flour, you can skip this step.

Add 1 cup of rolled oats to your blender or food processor.
Pulse the oats on high until they become the consistency of flour, which should take approximately 30 seconds to 1 minute.

Step Two: Add the Other Ingredients

Now that you have oat flour, measure out ¾ cup and mix with the other ingredients including flaxseed meal, almond flour, baking powder, ground cinnamon, water, salt, and vanilla extract. Mix well until the dough forms.

Step Three: Chill

Chilling the dough will make it easier to work with before shaping. Let the dough chill for at least 1 hour to firm up.

Step Four: Shape and Bake

Shape the dough into one log for longer biscotti or into two logs (6×2-inches) on a parchment paper-lined baking sheet.

I would suggest using gloves to work with the dough as it will be on the stickier side.

Bake the logs in a preheated 325°F oven for 25 to 30 minutes until golden brown and set at the centers. Allow them to cool completely for at least 2 hours or longer.

Once cooled, transfer the logs to a cutting board and cut into ¾-inch wide slices at a deep diagonal.

Step Five: Bake a Second Time

Place the cut biscotti on the same parchment paper-lined baking sheet and bake in a 300°F oven for 30-40 minutes.

The purpose of the second bake is to dry out the biscotti, making them crispy and crunchy.
