Preheat the oven to 400 degrees.

Stir the flour and water together in a large bowl well, making sure the flour mixes with the water and there aren't any pockets of flour. This will take a few minutes.

Stir in the broccoli florets and garlic powder to combine. Pour the mixture into a half sheetpan. Carefully transfer to the oven and bake for 25 to 30 minutes or until golden brown on the outside and firm. The longer the breadsticks cool for, the firmer they get, so keep that in mind in case yours seem gooey or too soft. Cut into preferred shapes and sizes (get creative with cookie cutters!) Serve or freeze.
