Method
Prepare and preheat
- Preheat the oven to 350°F and grease a 9x5-inch loaf pan or line with parchment; place a rack in the center of the oven.
Zucchini
- Grate the zucchini and place it in a clean kitchen towel; sprinkle lightly with salt and squeeze firmly to remove excess water, then measure out 2 cups packed.
Wet ingredients
- In a medium bowl whisk together the peanut butter, granulated sugar, brown sugar, egg, milk, and vanilla until smooth.
Dry ingredients
- In a separate bowl whisk the flour, baking powder, baking soda, salt, and cinnamon until combined.
Combine and bake
- Fold the dry ingredients into the wet mixture until just combined, then gently fold in the squeezed zucchini and the chocolate chips; if the batter is extremely thick, add up to 1 tablespoon more milk.
- Spread the batter into the prepared loaf pan and bake at 350°F for 50–60 minutes until the top is golden and a toothpick inserted in the center comes out with a few moist crumbs but not wet batter; tent with foil if the top browns too quickly.
- Cool in the pan on a wire rack for 10 minutes, then remove the loaf and cool an additional 30 minutes before slicing.
Notes
Squeeze the grated zucchini well—this prevents a soggy center. If using natural peanut butter, stir thoroughly and consider reducing milk by 1 tablespoon. The loaf keeps at room temperature for 3 days or freezes wrapped for up to 3 months; thaw overnight in the fridge before warming.
