If your dried cranberries aren't plump and moist, cover them with boiling water and let soak for 5 minutes. Drain them and pat dry before using.

　　If you prefer, walnuts or hazelnuts can be substituted for the pecans.

　　

Ingredients

Makes 24 mini-muffins

　　1 1/2 cups all-purpose flour

　　1/2 cup whole-wheat flour

　　1 tablespoon unsweetened cocoa powder

　　1 teaspoon baking powder

　　3/4 teaspoon kosher salt

　　1/2 teaspoon ground cinnamon

　　2 cups zucchini, coarsely grated (from about 2 medium)

　　2 large eggs

　　1/2 cup (packed) light brown sugar

　　1/2 cup sour cream

　　1/3 cup vegetable oil

　　1/2 cup dried cranberries

　　1/2 cup pecans, toasted and chopped

　　

Special Equipment

2 mini-muffin pans (preferably nonstick), each with 12 (1/8-cup) cups (each about 1 3/4 inches wide and 3/4 inch deep)

　　

Step 1

Position racks in upper and lower thirds of oven and preheat to 375°F. Butter muffin cups (if pans are not nonstick, butter liberally or spray with nonstick cooking spray).

　　

Step 2

In large bowl, whisk together all-purpose and whole-wheat flours, cocoa, baking powder, salt, and cinnamon. Stir in zucchini.

　　

Step 3

In medium bowl, whisk together eggs and brown sugar. Whisk in sour cream and oil. Fold wet mixture into dry until just combined (do not overmix). Gently fold in cranberries and pecans.

　　

Step 4

Divide batter among muffin cups, filling each cup 3/4 full. Bake until dark golden on top and toothpick inserted in center comes out clean, 10 to 12 minutes. Cool in pan on rack 10 minutes, then serve warm or turn out onto rack to cool completely. (Muffins can be made up to 3 days ahead and stored in airtight container at room temperature, or frozen in airtight container up to 2 weeks. Defrost in refrigerator, then rewarm, if desired, wrapped in foil in 300°F oven 7 to 10 minutes.)
