Preheat your oven to 400°F. Line a baking sheet with parchment paper or lightly grease it.

In a large bowl, mix flour, baking powder, and salt.

Slowly stir in warm water and melted butter. Mix until a dough forms.

Knead the dough on a floured surface for about 2 minutes until smooth.

Roll the dough out very thin—around 1/8 inch or thinner. The thinner, the crispier!

Cut into small squares or rectangles using a knife or pizza cutter.

Place the crackers on the prepared baking sheet. Use a fork to poke holes in the top of each cracker (this keeps them flat while baking).

Brush the tops with melted butter and sprinkle lightly with salt.

Bake for 10–12 minutes, or until golden and crisp. Watch closely to avoid burning.

Let cool before serving. Store in an airtight container to keep them crispy.
