Lemon Custard: In a mixing bowl or food processor, beat together 1 cup of milk, ½ cup heavy cream, box of instant vanilla pudding and lemon zest for about 1 minute, until completely combined. Place in a container and refrigerate until ready to use.
Guava Syrup: Mix ½ cup of guava nectar with 2 tablespoons of corn starch. Heat the remaining 1 ½ cups of guava nectar over medium heat until boiling, then reduce the heat to a simmer. Slowly whisk in the corn starch mixture and stir until the syrup has thickened. Keep Warm.
French Toast Batter: In a blender or food processor, combine 4 eggs, 1 teaspoon of vanilla extract and 1 tablespoon of sugar. Pour the mixture in a shallow bowl.
Combine ¾ cup of sugar and 2 teaspoons of cinnamon to create the cinnamon sugar coating.
Spread 1-2 tablespoons of lemon custard on a slice of bread and close like a sandwich.
Air Fryer Instructions: Set the air fryer to 320 degrees. Dip the bread in the batter and place in the air fryer after spraying with nonstick cooking spray. Cook the toast for 3 minutes, then flip over and cook the other side for 3 minutes. Remove the stuffed French Toast from the air fryer and brush with melted butter before coating with the cinnamon sugar mixture. Serve with warm guava syrup and whipped cream.
Frying Instructions: Heat the oil over medium high heat until it reaches about 350 degrees, then dip the French toast in the batter, covering both sides. Use tongs to carefully place the bread in the oil. Fry the French Toast on each side for 3-4 minutes until it is golden brown, then remove the toast from the pan and allow it to drain on a paper towel. Coat both sides of the crispy French Toast with the cinnamon sugar mixture and serve topped with guava syrup and whipped cream.
Traditional instructions: Heat a griddle to 325 degrees or frying pan on a stove over medium-high heat. Dip the French toast in the batter and coat both sides then place on a buttered surface. Cook each slice for 2-3 minutes until golden brown, then remove from the heat and coat with the cinnamon sugar mixture. Top with guava syrup and whipped cream.
