Stir together white whole wheat flour, sugar, 1/4 teaspoon salt, onion powder, garlic powder, paprika, and cayenne pepper.
Cut in butter with two forks or two knives or a pastry blender. You want it to look like crumbly sand.
Meanwhile, blend together water, lemon juice, hot sauce, and spinach. Pour spinach mixture into the flour-butter mixture.
Stir until well combined.
Roll out half of the dough on parchment paper or a silicone baking liner to 1/16 inch thick. Cut into squares or use a cookie cutter to cut into desired shapes. Sprinkle with some of the remaining salt.
Bake in preheated oven for 8-12 minutes, rotating the pans halfway through cooking time. Be careful to start watching the crackers around 8 minutes because they burn fast.
Repeat with the other half of the dough.
Store leftovers in an airtight container for up to 3 days.
