These tender chocolate chip zucchini muffins feature a moist crumb balanced with a crunchy buttery streusel topping. Perfect for breakfast, snacks, or brunch, they combine simple pantry ingredients with fresh zucchini for a delicious bakery-style treat.
Do not overmix the batter to keep muffins tender. Drain zucchini but do not dry completely to maintain moisture. Use room temperature eggs and melted butter for smooth batter. Chill streusel topping for best crumbly texture. Test doneness with a toothpick; a few moist crumbs are okay. Avoid opening oven door during baking to prevent sinking. For gluten-free, substitute flour with gluten-free blend containing xanthan gum. For vegan, use flax eggs, coconut yogurt, and vegan butter. Nuts in streusel are optional and can be replaced with toasted oats for nut-free version.
