- Use croissants that are at least a day old so they soak up the custard without turning mushy. If yours are very fresh, let the torn pieces dry on the counter for 10 to 15 minutes before assembling.
- You can use fresh or frozen berries. If using frozen berries, add them straight from the freezer without thawing.
- For a slightly lighter bake, replace the heavy cream with additional milk or half-and-half; bake time will be similar.
- Leftovers store well in the refrigerator for up to 2 days; reheat in a 325°F oven until warmed through.
