There are a couple of ways to do this, but in each you will need to start by combining all of the ingredients except for the butter and the bread and stirring well.
This first option only works if you want to make a stuffed French toast with only 2 pieces of bread, start by laying one piece of bread on a plate and add some of the filling mixture and few strawberries, and then top with the other piece of bread.
Now, carefully submerge the whole thing (both pieces of bread, with the filling) into the egg mixture, making sure to cover both sides completely.
Then, melt the butter in a skillet and add the French toast, cooking well on both sides until it is as done as you want.
The other way to do this is the cook each piece of French toast separately, and then adding a layer of the filling in between each piece of bread. This is the way that you will want to do it if you are doing two or more layers of bread.
Once cooked, top with syrup, powdered sugar, and more strawberries and enjoy!
