01 - Combine the chopped strawberries, granulated sugar, and lemon juice in a small saucepan. Set over medium heat and cook, stirring occasionally, for 5 to 7 minutes until the berries break down and the mixture thickens slightly. Remove from heat and let cool.
02 - In a medium mixing bowl, beat the softened cream cheese, powdered sugar, and vanilla extract together until smooth and creamy with no lumps remaining.
03 - Divide the cream cheese filling evenly among 4 slices of brioche, spreading it to the edges. Top each with a second slice of bread to form 4 filled sandwiches.
04 - In a shallow dish or baking pan, whisk together the eggs, milk, granulated sugar, cinnamon, vanilla extract, and salt until fully combined.
05 - Carefully dip each filled sandwich into the custard, coating both sides evenly. Avoid soaking too long to prevent the bread from becoming soggy.
06 - Heat a large skillet or griddle over medium heat and add a pat of butter. Cook each sandwich for 3 to 4 minutes per side until golden brown and cooked through.
07 - Cut each French toast diagonally in half and arrange on plates. Drizzle generously with the strawberry sauce, then finish with a dusting of powdered sugar and fresh strawberry slices if desired.
