In a shallow bowl, whisk together the eggs, milk, vanilla extract, cinnamon, and sugar until well combined.
Heat a skillet or griddle over medium heat and add the butter, allowing it to melt and coat the surface.
Dip each slice of bread into the egg mixture, making sure both sides are coated but not overly soaked.
Place the bread on the skillet and cook for 2 to 3 minutes on each side, or until golden brown and cooked through. Remove from the skillet and stack or plate as desired.
Top with sliced bananas, fresh blueberries, a drizzle of maple syrup or honey, and a light dusting of powdered sugar.
Serve warm and enjoy a breakfast that feels like a slow morning, even when it is not.
