Prepare Bread: Remove crusts from bread slices. Use a rolling pin to flatten each slice until thin.
Add Fillings: Spread about 1-1/2 teaspoons peanut butter on half of each bread slice. Add a small amount of chocolate spread on top.
Roll Up: Starting from the filled end, tightly roll each bread slice. Set aside.
Make Coating: In a large bowl, whisk together eggs, milk, vanilla, sugar, and cinnamon until smooth.
Cook Rolls: Heat butter in a large skillet over medium heat. Dip each roll in egg mixture, coating all sides. Cook rolls, turning every 2-3 minutes, until golden brown on all sides (about 8-10 minutes total).
Serve: Serve immediately while warm with your favorite toppings.
