Spread batter evenly in prepared pan then sprinkle 2 tablespoons of chocolate chips on top. (The batter may stick to your spatula, so I like to spray my spatula with nonstick cooking spray first.)
Adding an egg to the batter will make it more cake-like, but not vegan.
You can use your favorite nut butter, just make sure it’s all natural.
Feel free to add in other things according to your dietary needs like nuts, dried fruit, or other types of chocolate.
