1 1/2 c. all-purpose flour, plus more for working
1 c. whole wheat flour
1/2 c. untoasted wheat germ
1/2 tsp salt
1 tsp baking soda
1 tsp ground cinnamon
1 c. unsalted butter, softened (2 sticks)
3/4 c. packed light-brown sugar
2 TBSP high-quality honey
Directions:
Preheat over 350 F. Whisk flours, wheat germ, salt, baking soda, and cinnamon in a medium bowl - set aside.
Put butter, brown sugar, and honey into the bowl of an electric mixer fitted with the paddle attachment: mix on medium speed until pale and fluffy, 2 to 3 min., scraping down sides of the bowl as needed. Reduce speed to low. Add the flour mixture, and mix until combined.
Turn out dough onto a floured surface, and divide into quarters. Roll out each piece between 2 sheets of floured parchment paper into rectangles a bit larger than 9 x 6 inches, about 1/8" thick.
Using a fluted pastry wheel, trip the outermost edges or each rectangle and divide into three 6 x 3" rectangles. Pressingly lightly, so as not to cut all the way through, score each piece in half lengthwise and crosswise, to form four 3 by 1 1/2 inch crackers. Stack parchment and dough on a baking sheet and chill in freezer until firm, about 20 min.
Remove two sheets of dough from freezer. Pierce crackers using the tines of a fork. Transfer to large baking sheets lined with parchment paper. Bake, rotating halfway through, until dark golden brown, 8 to 9 min. Repeat with remaining dough. Let cool on sheet 5 min; transfer crackers to wire racks to cool completely.
