These Orange Blueberry Muffins are moist and tender, bursting with orange flavor and fresh sweet blueberries, the perfect compliment of flavors to start your morning off.
Center a rack in the oven and preheat the oven to 400 degrees F. Butter or spray the 12 molds in a regular-size muffin pan or fit the molds with paper muffin cups. Alternatively, use a silicone muffin pan, which needs neither greasing nor paper cups. Place the muffin pan on a baking sheet.
