In a large bowl, combine the water, sugar, and yeast. Let the mixture rest for 5 minutes, or until the yeast begins to bloom.

In a small bowl, whisk together the oil and ½ teaspoon salt.

Add the flour and remaining ½ teaspoon salt to the yeast mixture. Stir to combine.

Add the dough to a greased bowl and cover. Let it rise for 1 hour in a warm place, or until the dough has doubled in size.

Transfer the risen dough to the pizza pan. Work the dough to the edges and use your fingers to create dimples in the dough.

Bake for 10 minutes.

While the crust is baking for the first time, make the cinnamon butter and crumble.

To a microwave-safe bowl, add butter, granulated sugar, and cinnamon. Heat for about 30 seconds. Stir to combine.

To make the crumble topping, mix together the flour, granulated sugar, brown sugar, salt, and melted butter in a small bowl.

After the dough has been removed from the oven, brush the cinnamon butter over the crust in a thin layer, covering the entire surface.

Sprinkle the crumble topping over the cinnamon butter, covering the entire surface to the outer edge.

Place back into the oven for 10 minutes, or until the crumble is golden brown.

Remove from the oven and let cool for 5-10 minutes. While the bread is cooling, make the glaze.

In a separate bowl, mix confectioners' sugar and 1 tablespoon milk until smooth and creamy. If the glaze is too thick, add more milk, 1 teaspoon at a time, until it reaches your desired consistency.
