Preheat the oven to 350 degrees fahrenheit and line a baking sheet with parchment paper.
In a food processor, pulse together the gluten free all-purpose flour, brown sugar, ground cinnamon, baking soda, and salt.
Add the cubed cold butter and pulse until the mixture resembles coarse sand.
In a small bowl, mix the honey and milk. Add this to the food processor and pulse just until a dough ball forms.
Place the dough onto the parchment paper and roll it out into a large rectangle, about 1/8 inch thick. Use a knife to score the dough into squares and poke holes in each square with a fork.
Bake for 12 to 14 minutes until the edges are deep golden brown. Let cool completely on the baking sheet, where they will crisp up as they cool, then break along the scored lines.
