I imagine oat flour can be bought commercially as well, but grinding rolled oats does the trick just fine. I first learned about this method from a cookbook I checked out from the library a while back, Dreena Burton’s The Everyday Vegan.

The oat cracker dough:

• 2 dl rolled oats, finely ground
• 1 and 1/4 dl wheat flour
• 3/4 dl nutritional yeast
• 1/2 teaspoon baking soda
• 3/4 teaspoon salt
• 1/2 teaspoon dried thyme
• 1/2 teaspoon dried marjoram
• 1 teaspoon dried basil
• 1/3 teaspoon cayenne pepper (or to taste)
• 1/2 teaspoon turmeric (for color)
• 1 dl water
• 2 tablespoons olive oil
• 1 tablespoon lemon juice
• 1 teaspoon Dijon mustard
• 3 cloves garlic, crushed

I set the oven to 175 degrees Celsius, and proceeded to make the crackers exactly like the last time. The only thing I had to do differently was to ground the oats, which I did in our mini food processor. I processed them until they were fine, much like whole wheat flour.

I combined water, olive oil, lemon juice, mustard, and garlic, and placed the resulting wet mix in the fridge. Then I mixed the rest of the ingredients in a bowl, and covered a baking sheet with parchment paper. When the oven was ready, I added the fridge-cold wet mix to the dry mix bowl, stirred with a fork until combined, and rolled it out on the baking parchment with the help of a little bit of extra flour. I cut the cookies with a pastry wheel and baked them for 20 minutes, until nicely browned and crispy.
