Seedy Oat Crackers

1 cup old-fashioned oats
¾ cup raw pumpkin seeds (pepitas)
⅓ cup raw sunflower seeds
⅓ cup sesame seeds
3 tablespoons poppy seeds
1 teaspoon kosher salt
1 tablespoon plus 1 teaspoon olive or coconut oil
1 tablespoon pure maple syrup

Preheat oven to 350°. Mix oats, pumpkin seeds, sunflower seeds, sesame seeds, poppy seeds, and salt in a large bowl. Stir oil, maple syrup, and 1/2-3/4 cup room-temperature water in a medium bowl to combine. Pour liquid over oat mixture and toss until mixture is completely soaked. Let sit 10 minutes; mixture will absorb water and thicken.

Form oat mixture into a ball and transfer to a parchment-lined baking sheet. Press a second sheet of parchment paper directly on top and, using a rolling pin, flatten to 1/8″ thick (the shape doesn’t matter). Remove top layer of parchment.

Bake cracker until golden brown around edges, 15–20 minutes (watch it closely – it can burn!). Remove from oven and carefully turn out, parchment side up. Place a fresh sheet of parchment on baking sheet. Remove parchment from cracker, carefully turn cracker over, and return to baking sheet. Bake until firm and golden brown around edges, 15–20 minutes. Let cool on baking sheet, then break into pieces with your hands.

Do Ahead: Crackers can be made 1 week ahead. Store airtight at room temperature.
