Prepare the Bread: Using a sharp serrated knife, remove the crusts from the brioche loaf (you can save them for making breadcrumbs). Cut the loaf into thick 2-3 cm slices, and then cut these slices into 2-3 cm cubes. Set aside. Using slightly stale bread is a technique I learned that prevents sogginess, which is a common issue with making perfect French toast.

Make the Custard: In a wide, shallow bowl or dish, whisk together the eggs, whole milk, double cream, and vanilla extract until smooth and fully combined.

Prepare the Cinnamon Sugar: In a separate medium-sized bowl, mix the light brown sugar and ground cinnamon together until evenly distributed.

Soak the Bread: Working one cube at a time, dip each piece of brioche into the egg mixture. Let it soak for just 10-15 seconds per side. You want it to absorb the custard but not become completely saturated and fall apart. Place the soaked cubes on a wire rack or baking sheet as you go.

Heat the Pan: Place a large, non-stick frying pan or skillet over medium heat. Add about a tablespoon of the butter and allow it to melt and foam.

Fry the Bites: Carefully place a single layer of soaked bread cubes into the hot pan, ensuring you don't overcrowd it. I find that working in two or three batches gives the best results. Fry for 1-2 minutes per side, turning with tongs, until all sides are a deep golden brown and crisp.

Coat in Cinnamon Sugar: As soon as a batch is cooked, transfer the hot bites directly into the bowl of cinnamon sugar. Toss gently to coat them completely while they're still warm. Place the coated bites on a serving platter. Repeat with the remaining butter and bread cubes.

Make the Glaze: While the last batch is frying, prepare the glaze. In a small bowl, beat the softened cream cheese with the sifted icing sugar and vanilla until smooth. Gradually add the milk, one tablespoon at a time, whisking until you reach a smooth, pourable consistency.

Serve Immediately: Drizzle the cream cheese glaze generously over the warm platter of cinnamon roll French toast bites. Serve immediately for the best texture.
