**Prepare the Coating:**
In a small bowl, mix the sugar and cinnamon together.
**Heat the Skillet:**
Melt the butter in a nonstick skillet over medium heat.
**Add the Bananas:**
Arrange the banana slices in the skillet in a single layer. Sprinkle the cinnamon-sugar mixture evenly over the top.
**Cook and Flip:**
Cook for 2-3 minutes on one side until golden and caramelized. Gently flip the slices and cook for another 2-3 minutes until both sides are golden and slightly crisp.
**Serve Warm:**
Remove from the skillet and serve immediately. Drizzle with honey or maple syrup if desired.
