In a large bowl, whisk together the flour, baking soda, salt, and set aside
In a separate bowl, mix the cold butter & brown sugar, and with a dough whisk mix very well. Can also use an electric mixer or stand mixer for this.
Mix in dry ingredients to the butter and sugar mixture, until it's crumbly.
Add in sourdough discard, honey, and vanilla, and mix until soft dough forms.
Wrap dough in plastic wrap, and chill in the refrigerator for 30 mins- 1 hour.
Preheat oven: to 350°F (175°C). Line a baking sheet with parchment paper.
Bring dough out and divide in half.
On a lightly floured piece of parchment paper, roll out the dough to about 1/8-inch thickness.
Cut into rectangles or your preferred cracker shapes using a knife or cookie cutter. Transfer to the baking sheet.
Use a fork to prick each cracker a few times to prevent puffing.
Bake for 10-15 minutes, until golden brown and crispy. Keep an eye on the edges to avoid burning.
Cool on a wire rack. Once completely cooled, store in an airtight container.
