Very slightly modified from the recipe in smitten kitchen EVERY DAY
Makes 36 biscotti.
1 cup (130 grams) all purpose or whole wheat pastry flour
1.5 cups plus 2 tablespoons (130 grams) rolled oats
1 teaspoon baking powder
1/4 teaspoon baking soda
1/2 teaspoon table or fine sea salt
6 Tablespoons (85 grams) unsalted butter, melted, or virgin coconut oil, warmed until liquified
1/4 cup (50 grams) granulated or raw (turbinado) sugar
1/4 cup (50 grams) light- or dark-brown sugar
2 large eggs
1/2 teaspoon vanilla extract (optional)
1/2 cup (45 grams) thinly sliced almonds (I used slivered and it was fine)
1/2 cup (40 grams) shredded unsweetened coconut
1 cup (about 150 grams) dried fruit of your choice, such as raisins, cranberries, cherries or chopped dried apricots, or a mix
1 egg white (I skipped this and it was fine)
Mix the flour, rolled oats, baking powder, baking soda, and salt in a small bow. Whisk the melted butter (or coconut oil) and sugars in a large bowl. Whisk in the eggs and vanilla. Stir in the dry ingredients, nuts, coconut, and dried fruit. Expect a stiff batter.
Position a rack in the center of the oven, and heat to 325 degrees. Line a baking sheet with parchment paper.
OPn a floured board, using floured hands, roll half the dough into a log a little shy of the length of your baking sheet, 12 to 14 inches. Transfer the dough log to the baking sheet, and pat lightly to flat it to about 1/2″ thickness. Repeat with the second half of the dough. Beat the egg white until foamy, and brush it over the logs. Bake the logs for2 0 minutes, untl they are lightly golden brown and begnning to form crakcs.
Let cool almost completely (it’s okay if the centers are still lukewarm), about 1 hour. With a serrated knife, ut the logs on the bias into 1/2″-thick slices. They will be crumbly; cut as gently as possible. Transfer the slices back to the parchment-lined baking sheet, and lay on their cut side in a single layer. Bake for another 20 minutes, until toasted and crisp.
Cool on the baking sheet, or transfer to a rack.
NOTE: This recipe should prove very tweakable; you could use cinnamon, or almond extract, add citrus zest, very the fruits and sweeteners. You could add some chocolate chips.
DO AHEAD: They keep in an airtight container at room temp for up to 2 weeks, and longer if well wrapped in the freezer.
