For the lemon-berry cream cheese stuffing, place the freeze-dried berries in a food processor and pulse until a powder forms, about 30 seconds. Place the berry powder into a bowl with the cream cheese, fresh lemon zest and maple syrup, and stir thoroughly to combine. Set aside.
For the French Toast, place the milk, flour, sugar and vanilla extract in a large shallow bowl. Whisk to combine and set aside.
Carefully cut down ¾ of the middle of each slice of bread, creating a ‘pocket’, making sure not to cut all the way through. Stuff each slice of bread with about 1-2 scant tablespoons of the lemon-berry cream cheese and gently close. Continue until each slice of bread is stuffed. Soak the stuffed bread into the milk mixture until completely soaked through, about 1 minute per side.
In the meantime, place about 1-2 teaspoons of vegan butter in a large non-stick killet over medium heat. Once the bitter is melted, work in batches to fry each piece of stuffed toast until golden and crispy, about 2 to 3 minutes per side. Repeat with the remaining pieces of stuffed toast, adding 1 to 2 teaspoons of butter to the pan as needed.
Serve each with a generous sprinkle of powdered sugar, whipped cream, fresh berries, a pat of vegan butter and maple syrup, and enjoy!
