In a shallow bowl, combine the granulated sugar and ground cinnamon, mixing well until evenly incorporated.

Remove the crusts from each slice of bread. Optionally, press down on each slice to flatten it slightly, which will make the cookies crispier. Cut each slice diagonally into four triangles.

Using a pastry brush, generously brush melted butter onto both sides of each bread triangle. Immediately dip both sides of the buttered bread into the cinnamon sugar mixture, ensuring it's well coated. Place on the prepared baking sheet. Repeat with all bread pieces, using all of the melted butter and cinnamon sugar mixture.

Bake for 20-25 minutes, until the bread is lightly browned and toasted. For even baking, rotate the baking sheet halfway through the baking time.

Immediately transfer the toasts to a cooling rack to allow them to cool completely and become crisp. The cookies will continue to crisp up as they cool.
