Cube up leftover banana bread, and toast it until slightly crunchy and dried out.
About 4 cups of bread cubes work with:
2 cups milk
1/2 cup cream
1 tbsp vanilla
1/3 cup sugar
Whisk all ingredients together.
In greased baking dish place the banana bread cubes, top with blueberries (or whatever fruit you have on hand – fresh or frozen) and pour the egg/milk mixture over. It should just cover the bread cubes and fruit.
Bake at 350 degrees for between 45-60 minutes. A knife inserted in the middle should come out clean.
