Steps
1. In a shallow bowl, whisk together the egg, milk, and vanilla extract until well combined.
2. Heat a non-stick skillet over medium heat and melt the unsalted butter.
3. Dip the brioche slice into the egg mixture, ensuring both sides are fully soaked but not soggy.
4. Place the soaked bread on the skillet and cook for about 2-3 minutes per side, or until golden brown.
5. Remove the toast from the skillet and spread the softened vanilla butter evenly on top while it's still warm.
6. Spoon the red berry jelly over the buttered toast, spreading gently.
7. Sprinkle the diced fresh strawberries over the jelly layer.
8. Transfer the assembled French toast to a round plate and optionally dust lightly with powdered sugar for a finishing touch.
9. Serve immediately and enjoy!
