01 -  Preheat oven to 350°F (175°C). Line a 12-cup muffin pan with paper liners or grease thoroughly. 
 02 -  In a large mixing bowl, combine flour, baking powder, baking soda, ground ginger, and salt. Whisk until fully blended. 
 03 -  In a separate bowl, whisk together melted butter, maple syrup, cream soda, eggs, and vanilla extract until smooth consistency is achieved. 
 04 -  Pour the wet mixture into the dry ingredients. Stir gently until just combined to avoid overmixing. 
 05 -  Fold in the chopped crystallized ginger and white chocolate chips, if desired. 
 06 -  Evenly distribute the batter into the prepared muffin cups. 
 07 -  Place muffin pan in the oven and bake for 16 to 18 minutes. Muffins are done when a toothpick inserted into the center emerges clean. 
 08 -  Allow muffins to cool in the pan for 5 minutes, then transfer to cooling rack. When just warm, insert a popsicle stick vertically into the base of each muffin. 
 09 -  Let cooled muffins rest until completely set before serving.
