Whisk the eggs in a low shallow dish or use a 13- x 9-inch baking dish. Add the milk, sugar and vanilla extract and whisk again until well combined.

Add 1 tablespoon butter to a skillet and place over medium heat. Coat one slice of brioche in the egg mixture. When butter has melted, add the coated brioche. Cook for 3 to 4 minutes until golden brown, then flip and cook for another 3 to 4 minutes.

Transfer the French toast to a platter and keep warm. If no warming tray is available, place on a baking sheet and transfer to a 200 degree oven until ready to serve.

Wipe down the skillet with a paper towel and repeat the process with remaining butter, bread, and egg mixture.

Serve immediately with warmed maple syrup and fresh berries.
