In a medium bowl, with an immersion blender, mix together the eggs, half and half, sugar, cinnamon, vanilla and pinch of salt.
Baking
Lay the stuffed bread slices in a single layer in a large baking pan.
Pour the batter all over the stuffed bread slices.
Cover with aluminum foil and refrigerate overnight.
In the morning or before brunch is served pre-heat the oven to 350 degrees.
Remove the batter-soaked stuffed toast from the batter.
Melt a generous amount of high-quality butter in a heavy frying pan (such as cast iron).
Place the battered, stuffed bread slices into the hot butter and cook until a nice golden-brown color appears.
Place the prepared french toast in an uncovered baking dish in the heated oven and bake for 1/2 hour.
Dust with powdered sugar.
Garnish with raspberries.
Serve immediately out of the oven with warm maple syrup
