Mix the cream, milk, sugar, vanilla and eggs. Toss the brioche cubes into the mixture. Let sit for 15 minutes, stirring once or twice.
Place half of the brioche cubes in a 4.5-quart Crock-Pot Brand(R) slow cooker. Sprinkle half of the chocolate chips and raspberries over it. Repeat the layers with the remaining brioche, chocolate chips and raspberries.
Cover, and cook on HIGH for 1 1/2 to 2 hours.
