Preheat your skillet over medium heat until it feels warm to the touch.
Spread a thin layer of butter on each slice of gluten-free bread, coating the surface evenly.
In a small bowl, mix together the cinnamon and sugar until well combined, creating a fragrant cinnamon sugar mixture.
Dip each buttered bread slice quickly into the cinnamon sugar mixture, ensuring both sides are coated evenly with the fragrant spice blend.
Place the coated slices in the preheated skillet and cook for about 2-3 minutes, or until the bottoms are golden brown and aromatic.
Carefully flip each slice using a spatula, and cook for an additional 2 minutes until the other side is crispy and deep golden.
Remove the slices from the skillet and let them sit for a minute; this helps the cinnamon aroma to intensify and the texture to settle.
Drizzle each warm slice with honey or add a dollop of Greek yogurt for extra creaminess and flavor contrast.
Serve immediately while still warm, enjoying the crunchy exterior and soft, spiced interior with a fragrant aroma.
