I baked some graham crackers for them in my bakery. Which they ate in their bakery.
Homemade graham crackers? Easy and tasty!
Honey Graham Crackers
2 C whole wheat flour
2 tsp. baking powder
1/4 tsp. salt
3 Tbsp. brown sugar
1/2 C butter, softened
2 Tbsp. honey
2 Tbsp. milk
Combine flour, baking powder, salt, and brown sugar. Cut in butter. Mix in honey and milk, forming a ball. [Note--I'm guessing that a good pastry cutter or a food processor would work well. Since I have neither, I just mix everything with my hands.] Roll out the dough on a lightly greased large cookie sheet or baking stone, 1/8" to 1/4" thick. Prick with a fork and score with a pizza cutter. Bake at 400 degrees for 10-12 minutes, until lightly browned.
Update: If you use a baking stone, preheat it. Roll the dough onto parchment paper, and, after pricking and scoring, transfer it to the pizza stone. Either use a pizza peel or the back of a baking pan. Reduce the baking time by a few minutes.
