Preheat the oven to 350 degrees F. Grease a 9x13 inch baking dish.
Cut each of the brioche bread slices into 6 pieces.
Chop the apples slices in the apple pie filling into smaller pieces.
Whisk together the milk, eggs, sugar, vanilla and cinnamon.
Pour over the bread in a large bowl and gently fold together, then fold in the chopped apple pie filling.
Transfer into the baking dish in an even layer and bake for 40 to 45 minutes, until golden and set in the center.
Set aside for a few minutes to finish cooking and set up. Serve warm or room temp. Vanilla ice cream is a great accompaniment.
