In a large mixing bowl, add water, yeast, sugar, salt, and olive oil. Let it stand for 5 minutes. Add 1 cup of flour, and mix until combined. Add another cup of flour, and mix for 1-2 minutes until batter-like. The dough will develop gluten with this process.

Add the remaining flour, knead by hand until smooth and elastic, about 6 to 10 minutes. Cover with a towel and let rise in a warm place for 15 to 60 minutes.

Preheat oven to 375°F. Divide dough in half. Roll out one half on parchment to about 1/2 inch thick. Deeply dimple the surface, pour melted butter, sprinkle cinnamon and sugar. Bake for 15-18 minutes until golden. Cool for 5 minutes, then cut into 4-inch sticks.

To prepare the dipping sauce, mix melted 3 tablespoons butter with powdered sugar and 1.5 tablespoons milk until smooth.
