Creating Creamy Blueberry Cream Cheese Stuffed French Toast is simple when you follow these steps:

1. Prepare the Filling: In a medium bowl, mix the softened cream cheese, blueberries, granulated sugar, and vanilla extract until well combined. Set aside.
2. Make the Egg Mixture: In another bowl, whisk together the eggs, milk, and cinnamon until smooth.
3. Assemble the Toast: Take a slice of bread and spread a generous amount of the cream cheese filling on one side. Top it with another slice of bread to make a sandwich.
4. Dip the Sandwich: Carefully dip the sandwich into the egg mixture, making sure to coat both sides well.
5. Heat the Pan: In a large skillet or griddle, melt the butter over medium heat until it foams.
6. Cook the French Toast: Place the dipped sandwiches in the skillet and cook for 3-4 minutes on each side, or until golden brown and cooked through.
7. Repeat: Continue the process with the remaining sandwiches, adding more butter to the pan as needed.
8. Serve Hot: Once all the French toast is cooked, serve immediately with maple syrup and a dusting of powdered sugar, if desired.

Following these straightforward steps will ensure that your Creamy Blueberry Cream Cheese Stuffed French Toast turns out perfectly.
