In a medium-sized bowl, whisk together all 3 flours, the baking soda salt, and cinnamon if using; set aside for later.
In the bowl of a stand mixer, combine the butter, brown sugars and honey, beat together at medium-high speed until the butter/sugar mixture is light and fluffy, about 2 minutes.
Once light and fluffy scrape the sides of the bowl down. Add the dry ingredients into the butter mixture and mix on low speed just until its combined and the dough comes together, which takes about 30 seconds.
Transfer the dough onto 2 pieces of plastic wrap separating best as you can into two balls of dough; shape the dough balls into 2 a 5-inch disks about an inch thick, and wrap tightly. Refrigerate the dough disks for at least 2 hours, or if not using yet refrigerate up to 5 days.
After your dough has refrigerated and you are ready to bake the graham crackers, preheat your oven to 350 degrees F and take your dough out for about 10 min to warm up slightly.
Get 3 baking sheets out but don’t put parchment paper down yet, only cut 2 pieces out and make them the same size you would if putting on the baking sheets. Put one sheet on your counter and grab one of your disks put the other sheet on top of the disk. Between the two pieces of parchment paper roll out the dough to a 1/8-inch thickness
Take one of your parchment pieces and place them onto the baking sheet. Cut into 2-inch and 1inch rounds then transfer them to the baking sheet, spacing the crackers at least ¾-inch apart, grab the other dough and another piece of parchment and roll the other disk follow above directions with the scraps.
Only 2 trays at a time bake the crackers for 6 minutes and then rotate the baking sheet. Bake for another 6 to 8 minutes, or until the cookies are golden brown and just slightly firm to the touch.
Let them cool for one minute on the baking sheets, then transfer them onto a cooling rack. Let them cool completely (they will get crispy as they cool). They stay fresh in an alright container for up to 5 days, they freeze nicely too if you place them into a zip lock bag, I wouldn’t freeze longer than 2 months.
