Preheat oven to 350 degrees F.
Cut French bread into 1/2 to 1-inch cubes and set aside.
Add the eggs to a medium bowl and beat slightly. Add the cream, sugar, cinnamon, and vanilla and mix until well blended. Add the blueberries and fold in.
Pour the liquid over the cubed bread and fold in until the liquid is absorbed into the bread cubes. Spray the muffin tins with a non-stick cooking spray.
Fill the muffin tins with the French toast mixture just to the top. Place in the preheated oven for 20 to 25 or until slightly browned
Remove from the oven and remove the muffins from the tins. Serve with maple syrup or your favorite topping.
