Add the wet mixture to the dry one and gently combine—don’t stir too much. Toss in chocolate chips and any optional add-ins like nuts or dried fruit.

Pour the batter into the pan you prepared earlier. Bake it in the oven for 55 to 65 minutes. A toothpick stuck in the center should come out clean. If the top gets too dark, cover it loosely with foil.

Let the bread sit in the pan for about 10 minutes before moving it to a cooling rack. Wait until it’s fully cool to slice. Sprinkle with powdered sugar if you like!
