Begin by preheating your oven to 350°F (180°C). Set a baking sheet with parchment paper and place a wire rack on top to prepare for baking the French toast.

In a baking dish measuring 9x13 inches, pour the heavy cream in. In a separate bowl, mix 1 cup of sugar with cinnamon, then stir this blend into the cream along with the egg yolks and vanilla. Whisk until smooth and well combined.

Dip each slice of brioche into the cream mixture, ensuring both sides are adequately coated. Arrange the coated slices on the wire rack.

Bake the dipped brioche for 15 minutes, then flip each slice over and continue baking for an additional 15 minutes until they achieve a slightly crispy texture.

While the French toast is in the oven, prepare the strawberries by slicing them into decorative shapes such as fans or roses for an appealing presentation.

When baking is complete, sprinkle the remaining sugar over the top of the slices and broil on high for approximately 3 minutes until the sugar melts and turns a golden brown color. Alternatively, you can use a kitchen torch for a classic brûlée finish.

Serve your golden brown French toast warm, topped with whipped cream and the beautifully arranged strawberries. Enjoy your delightful breakfast!
