Make the Cinnamon Roll French Toast Sticks
Make sure your bread is thawed and at room temperature
In a small mixing bowl, stir together ½ stick butter, 1 teaspoon cinnamon, and ⅓ cup brown sugar
Spread 1 tablespoon of butter and sugar mixture onto slice of bread
Spread 1 tablespoon cream cheese icing on top of butter and sugar mixture and top with another slice of bread (the icing will hold the pieces of bread together)
Continue until you have 5-6 “sandwiches” made
In a shallow dish, combine eggs, milk, vanilla, and 1 teaspoon cinnamon
Dip each “sandwich” into the egg mixture until both sides are coated well
Preheat a skillet to medium heat and lightly spray it with oil (see notes for using a griddle)
Add French toast “sandwich” to skillet and cook for about 1 minute per side until golden brown
Transfer to a plate or cutting board to rest
Continue until all French toast has been cooked
Cut “sandwich” into 3 French toast sticks and drizzle with cream cheese icing
