Preheat oven to 350 degrees.
In a food processor or mixer combine the first 6 ingredients. (If using wheat germ or flax seed add here.)
Add cubed and chilled butter to the mix and pulse/mix until it resembles coarse meal.
Add honey, water, and vanilla and continue to mix until it all combines.
Remove and shape the dough into a flat disk and place between two pieces of wax or parchment paper. (I found it easier to roll the dough w/o a sheet on top of the dough. If the dough seems to be slightly sticky, lightly cover the wax paper with flour.)
Roll dough out until ¼ inch thick. Cut out desired alphabet letters or other shapes. Combine the dough scraps and roll out again to cut more letters.
Place cookies on a Silpat or parchment lined baking sheet and bake for 8-10. (This will result in a softer, cookie-like graham cracker if you want it crispier like a graham cracker bake for up to 13 minutes.)
Cool and serve.
Cover with melted chocolate and sprinkles if desired.
