In a large bowl, add the egg and whisk until beaten. Add the milk, sugar, cocoa powder, vanilla extract, and salt, and whisk until combined.
Add the bread to the mixture, and toss until well coated. Let soak for 30 minutes, tossing occasionally.
Preheat oven to 350° F.
Fold chocolate chips and raspberries in to the bread mixture.
Spoon bread mixture into two small ramekins. Fill almost to the top, and spoon in the excess liquid until the ramekin is about 2/3 full of liquid, in addition to the bread mixture. There will be some leftover liquid that you won't use.
Place ramekins on a baking sheet, and bake for 30 minutes, or until they're still moist but not too wobbly.
Let cool slightly before serving.
