I start by adding the raw sunflower seeds to my food processor and pulsing until they turn into a fine, sandy meal. I stop before it turns into seed butter a coarse, flour-like texture is exactly what this dough needs. This step is what replaces nuts entirely while still giving the crackers a rich, toasty base flavor.
Next, I pour the seed meal into a mixing bowl and add the oat flour, baking powder, salt, and cinnamon, stirring them together first. Then I add the egg, honey, melted coconut oil, and vanilla, mixing until a soft, slightly sticky dough forms. It should hold together easily when I press a bit between my fingers.
I wrap the dough or cover the bowl and pop it in the fridge for about 30 minutes. This short rest firms up the coconut oil and makes the dough far easier to roll without sticking everywhere. I don't skip this step, even when I'm in a hurry, because it really does change the texture.
Once chilled, I place the dough between two sheets of parchment paper and roll it out to about 1/8-inch thickness. Thinner dough means crispier crackers, so I try not to rush this part. Then I cut it into small squares, circles, or fun shapes using cookie cutters or a knife.
I transfer the shapes onto a lined baking sheet, spacing them slightly apart, and bake at 300°F for about 15 minutes. I watch the edges for a light golden color, since oven times can vary a little. They'll firm up more as they cool, so slightly soft crackers straight from the oven are completely normal.
Finally, I move the crackers to a wire rack and let them cool all the way before touching them again. This last step is what turns them from "soft and bendy" into that satisfying, snappy crunch everyone loves. Skipping it means softer crackers that don't hold up as well in a lunchbox.
