Moist muffins for breakfast or any time of day!
Preheat the oven to 300ºF (150ºC).
Add chocolate chip pieces and chopped walnuts into the mixture, then gradually combine them by using a spatula.
Bake for 20-25 minutes, until the tops are lightly brown and check them by inserting a toothpick into the center of a muffin and it should come out clean.
