Preheat oven to 350 degrees F. Line a baking sheet with parchment paper. Set aside.
Combine all the dry ingredients, including the ground spices, into a mxing bowl.
In a separate bowl, combine the almond milk, maple syrup, and vanilla with a whisk. Add the wet ingredients into the dry ingredients. Stir to combine.
Add the chopped crystallized ginger (do NOT leave this ingredient out!) and stir to ensure thoroughly distributed throughout the batter.
Transfer dough onto the lined baking sheet and shape into a log (10 inch long by 2 inches wide). Gluten free doughs can be sticky so I find it's easy to shape the dough using a piece of plastic wrap.
Bake for 15 minutes. Remove from oven and allow to cool on the baking sheet for about an hour).
Carefully transfer the cooled biscotti "log" onto a cutting board and slice into 12 pieces, using a serrated knife. Place each sliced cookie back onto the parchment lined baking sheet.
Reduce the oven temperature to 310 degrees and bake for 15 minutes, flip, and then bake for another 10-15 minutes. Transfer each biscotti onto a cooling rack and cool completely.
