Pre-heat the oven to 350 F, and line a baking dish with parchment. Then, if blending your own oat flour / making cashew butter at home, do that now (see the description in the post above for a "how-to").
Combine pitted dates and 1/4 cup water in a microwavable bowl. Heat them for 40-60 seconds in the microwave so the dates become warm and very soft so they'll be easier to blend.
Add the dates and warm date-infused water to the blender along with the cashew butter, vanilla, cinnamon, and baking powder to the blender. Blend until smooth.
Add the oat flour to the blender. Blend briefly just until everything is combined.
Form the dough into balls roughly 12 grams each and place them on a parchment lined baking sheet. Note: I use a ceramic baking dish rather than a regular tin one since I have a very small oven with the rack right above the flame (so if you're in the same boat, I recommend this over a traditional baking tray so your cookies cook evenly and don't burn).
Leave a couple inches between the cookies. Press down with a clean fork to create a criss-cross pattern on each cookie. If you press down a lot, you'll get thinner, drier cookies. If you press down just enough to create the criss cross, you'll get chewier, more moist cookies. The ones pictured are the chewy, moist variety (which we prefer).
Bake for 9-11 minutes. For me, 10 minutes is perfect, but each oven is a little different. Watch closely. They should seem a little underbaked when you take them out. DO NOT OVER-BAKE. If you do, you'll end up with hockey pucks. When I make a new recipe, I always do a "test" with just one cookie before I cook the whole batch just to find what works for my oven.
Let the cookies firm up for a few minutes on the cookie tray before transferring them to a cookie rack for another 20 minutes. If dipping in chocolate, place the cookies in the freezer for a few minutes to make them easier to dip. Then heat the chocolate in 10 second increments in the microwave until it is smooth, and dip and drizzle to your heart's content :) Add the nuts or seeds before the chocolate hardens if you want a little crunch. Let them cool a bit so the chocolate hardens if you can. Or don't bother!
