1. In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until well combined.
2. Add the brioche cubes to the bowl, gently folding them into the egg mixture until each piece is thoroughly soaked. Let them sit for about 5 minutes to absorb the flavors.
3. While the bread is soaking, heat a large non-stick skillet over medium heat and melt the unsalted butter.
4. Once the butter begins to sizzle, carefully add the soaked bread cubes to the skillet, ensuring they are evenly spaced. Cook for about 3-4 minutes on each side, until they are golden brown and crisp.
5. Transfer the cooked bites to a serving platter, dusting generously with powdered sugar for a sweet, finishing touch.
6. Serve immediately with a drizzle of maple syrup, creating a delightful contrast of flavors and textures.

Remember, patience is key. As my grandmother, Nonna Rosa, would say, “Good things take time, just like a perfectly simmered marinara.” Take your time to achieve that perfect golden crust.
