In a shallow dish, whisk together large eggs, whole milk, vanilla extract, ground cinnamon, salt, and granulated sugar until smooth.

In a separate bowl, combine granulated sugar and additional ground cinnamon to create the churro-like coating.

Heat a skillet over medium heat and add unsalted butter.

Dip each thick-cut slice of bread into the custard mixture for about 10 seconds per side.

Place soaked bread slices in the skillet and cook for approximately 3-4 minutes per side.

Transfer cooked slices to the bowl with the cinnamon sugar, coating both sides generously.

Serve immediately, drizzling with caramel or chocolate sauce and garnishing with fresh berries or whipped cream.
