In a mixing bowl, whisk together 3 medium-sized room temperature eggs and 1 cup of whole milk until well blended. Mix in 2 tablespoons of sugar, a teaspoon of ground cinnamon, and a teaspoon of vanilla essence if desired.

Slice stale bread into 1-inch thick pieces and lay them on a cutting board.

Dip each slice of bread into the custard, soaking for about 30 seconds on each side, then set aside on a plate.

Heat a non-stick skillet over medium heat, add 2 tablespoons of butter, and let it melt. Place soaked bread slices into the skillet and cook for about 5 minutes on each side until golden brown.

Check doneness by pressing lightly on the slices; they should spring back slightly. Remove once both sides are golden brown.

Serve immediately, drizzling with pure maple syrup or topping with fresh fruits and whipped cream.
