Step 1

Preheat oven to 400 degrees F (200 degrees C). Grease 2 baking sheets.

Step 2

Stir flour, flax seeds, chia seeds, baking powder, salt, garlic powder, onion powder, and dried chipotle pepper powder together in a large bowl. Cut butter into flour mixture with a pastry cutter until mixture resembles coarse crumbs.

Step 3

Stir water and olive oil into butter-flour mixture with a fork until dough sticks together and pulls easily off the sides of the bowl. Divide dough into 2 portions.

Step 4

Turn 1 dough portion out onto a floured work surface and roll out as thin as possible. Cut dough into squares and place on prepared baking sheet. Repeat with remaining dough.

Step 5

Bake in the preheated oven until crackers are golden and crispy, about 8 minutes. Transfer to a wire rack to cool completely.
