Preheat the oven to 425°F.
In a medium bowl, combine pancake mix, cheese powder and water.
Stir until blended. Sprinkle with additional dry pancake mix and knead for 5 minutes.
Coat a baking sheet with cooking spray. Place dough on the center of the baking sheet and roll into a very thin rectangle.
The dough will want to puff up a little. Using a knife or pizza cutter, cut dough into cracker-size squares (about 1 1/2-inch square).
Pierce each square two times with a fork. Sprinkle it with sea salt. Bake for 12 minutes. Edges should be light brown. Crackers become crisp as they cool.
