In a mixing bowl, combine warm water, sugar, and yeast. Let it sit for 5 minutes until frothy.

Add flour, salt, and olive oil to the yeast mixture. Mix until a dough forms.

Knead the dough on a floured surface for about 5 minutes until smooth.

Place the dough in a greased bowl, cover with plastic wrap, and let it rise in a warm place for 1 hour.

Preheat the oven to 375°F (190°C).

Once the dough has risen, punch it down and spread it onto a greased baking sheet.

In a small bowl, mix cinnamon and sugar. Sprinkle this mixture evenly over the dough.

Drizzle melted butter over the top.

Let the dough rise for another 20 minutes.

Bake in the preheated oven for 20-25 minutes or until golden brown.

Allow the focaccia to cool slightly before slicing. Serve warm or at room temperature.
