Ingredients

1 1/4 cups whole-wheat flour, plus more for dusting 

1/2 cup toasted wheat germ 

1/4 cup sunflower seeds 

1 teaspoon ground cumin 

1/2 teaspoon baking powder 

1/2 teaspoon baking soda 

1/2 teaspoon salt 

3 tablespoons unsalted butter, cut into pieces 

1/2 cup nonfat buttermilk 

Coarse salt, for sprinkling 

Vegetable-oil cooking spray 

Preparation

Preheat oven to 350 degrees. Spray two baking sheets with cooking spray; set aside. In the bowl of a food processor, pulse flour, wheat germ, sunflower seeds, cumin, baking powder, baking soda, and salt. Add butter; process until mixture resembles coarse meal. With machine running, gradually add buttermilk; process until dough comes together and is moist.

Transfer to a lightly floured surface. Allow to rest for 5 minutes. Roll until 1/4 to 1/8 inch thick. Sprinkle with coarse salt; roll to press salt into dough.

Cut dough into 4-inch-long leaf shapes, or other desired shape. Transfer the leaves to ungreased baking sheets. Pierce each cracker liberally with a fork. Bake until hard, about 16 minutes. Transfer crackers to a wire rack to cool. Store in an airtight plastic container, at room temperature, up to 1 week.
