It’s extremely important to measure both the oats and flour correctly using the spoon-and-level method or a kitchen scale. Too much of either will dry out the cookies and leave them crumbly instead of chewy.

Instant oats are also known as quick-cooking or minute oats. They come in large canisters, just like old-fashioned oats. They are not the ones in the small flavored packets of oatmeal. To make your own, add the same amount of old-fashioned oats to a food processor, and pulse 10-12 times.

For a gluten-free version, use gluten-free instant oats and a gluten-free flour blend. I recommend the following blend: ½ cup (60g) millet flour, 2 tablespoons (15g) tapioca flour, 2 tablespoons (17g) brown rice flour, and ½ teaspoon xanthan gum.

If you prefer, pure 1/4 C maple syrup or honey or agave may be substituted in place of the brown sugar and milk.

For the best results, use fresh raisins. Older raisins will be drier, so I recommend hydrating them first. Add the raisins to a microwave-safe bowl, cover them completely with water, and top with a tight-fitting lid or plastic wrap. Microwave on HIGH for 45-60 seconds. Let the raisins sit and absorb moisture until you’re ready to add them to the dough. Drain them thoroughly before folding in.
