Preheat the oven to 350°F (175°C).

Line a baking sheet with parchment paper.

In a large mixing bowl, whisk together the all-purpose flour, whole wheat flour, brown sugar, baking soda, salt, and cinnamon.

Add the cold, cubed butter to the dry ingredients and mix until it resembles coarse crumbs.

Stir in the honey and milk until the dough comes together.

Turn the dough onto a floured surface and roll it out to about 1/8 inch thickness.

Cut the rolled dough into squares or rectangles.

Transfer the cut dough to the prepared baking sheet and bake for 12-15 minutes until golden.

Let the crackers cool on a wire rack for maximum crunchiness.
