Step 1

Preheat the oven to 300°F (150°C). Adjust a rack to the lowest part of the oven. Lay a piece of parchment paper on a clean part of the counter.

Step 2

In a large bowl, combine the pepitas, sunflower seeds, flaxseed, flaxseed meal, sesame seeds, almond flour, hemp hearts, psyllium powder, and 1½ teaspoons salt. Mix in the coconut oil and boiling water to form a somewhat gelatinous dough ball.

Step 3

Scoop the dough out onto the prepared parchment paper. Cover it with a second piece of parchment and use your hands and a rolling pin to evenly flatten the dough into a 6-inch by 12-inch rectangle.

Step 4

Slide the dough and the top and bottom paper onto a baking sheet. Peel off and discard the top layer of parchment, then bake the crackers on the parchment until somewhat firm and golden around the edges, about 30 minutes.

Step 5

Remove the crackers from the oven, use a pizza cutter or knife to slice the giant cracker into 32 (1-1/2 -inch) squares, then continue baking until crisp, another 20 to 25 minutes. Turn off the oven, then leave the crackers inside to thoroughly dry, 3 hours. Enjoy!
