I found this online after having some at a little 50's type diner. I don't recall where online. I think the filling needs to be played with till it gets a creamy smooth texture.
- Mix filling together.
- Spread on bread and place 2 slices together.
- Soak 5 minutes.
- Melt butter in a pan. Fry each french toast 2 minutes per side over medium heat.
