Whisk together the eggs, milk, vanilla extract, and salt in a shallow dish until well combined. Heat a non-stick skillet or griddle over medium heat and add a small amount of butter to grease the surface.
Dip each slice of babka into the egg mixture, ensuring both sides are well-coated but not overly soaked. Allow the babka to soak for a few seconds, but avoid over-saturating to prevent sogginess.
Place the coated babka slices on the preheated skillet or griddle. Cook for 2-3 minutes on each side or until golden brown and cooked through. Adjust the heat as needed during cooking.
Repeat the process for all babka slices, adding more butter as needed.
Once cooked, transfer the babka French toast slices to a serving plate.
Serve warm, topped with your choice of powdered sugar, maple syrup, fresh berries, or whipped cream.
