1
Preheat the oven to 325F.
-
2
Line a baking sheet with parchment paper.
-
3
Whisk together the flour mix, xanthan gum, baking powder, and salt.
-
4
Set aside.
-
5
In a small bowl, whisk together 5 tablespoons of the orange juice with the cornstarch.
-
6
Set aside.
-
7
In the bowl of a stand mixer fitted with the paddle attachment, combine 1 cup of the sugar with the remaining 1/2 cup orange juice, mixing on medium speed for about 20 seconds.
-
8
Add the canola oil and vanilla and mix for about 1 minute.
-
9
Add the cornstarch mixture, and mix until combined, about 20 seconds.
-
10
Add the flour mixture in two batches, mixing on low speed.
-
11
Fold in the cranberries and chocolate chips using either a wooden spoon or a rubber spatula.
-
12
Dust the parchment paper with a little flour mix, and transfer the dough to the lined baking sheet using a rubber spatula.
-
13
Sprinkle a little more fl our mix onto the dough, flour your hands, and divide the dough in half.
-
14
Shape the dough into two mounded logs on the baking sheet.
-
15
The dough will be sticky, so make sure your hands are really well floured.
-
16
The logs should be 8 inches long by 4 inches wide by 1 inch high.
-
17
Using a pastry brush, brush the tops of the logs liberally with the rice milk.
-
18
Then sprinkle the tops with the remaining 2 tablespoons sugar.
-
19
Bake in the center of the oven for 35 minutes.
-
20
Remove the baking sheet from the oven and reduce the temperature to 300F.
-
21
Let cool for 20 minutes, then lift the logs off the parchment paper (if they stick, use a frosting spatula to gently loosen them by sliding it gently under the bottom).
-
22
Slice each log diagonally into 12 slices.
-
23
I cut each log in half first, then into quarters, and then each quarter into 3 slices.
-
24
I use a sharp serrated knife to do this.
-
25
Return the slices to the baking sheet.
-
26
Bake for 20 minutes, remove from the oven, flip the cookies, and bake for 20 minutes more, or until lightly golden.
-
27
Remove from the oven and transfer the biscotti to a cooling rack.
-
28
They will become extra crisp once they cool.
