01 -  Preheat oven to 350°F. Line a baking sheet with parchment paper. 
 02 -  Whisk together flour, baking powder, baking soda, salt, matcha powder, cinnamon, ginger, and nutmeg in a medium bowl. 
 03 -  In a large bowl, beat granulated sugar, brown sugar, and eggs until light and creamy. Stir in vegetable oil, pumpkin puree, milk, and vanilla extract. 
 04 -  Gradually fold dry ingredients into wet mixture until just combined. Avoid overmixing to maintain tenderness. 
 05 -  Roll out pie crusts and use a round 2.5-inch cookie cutter to cut out 24 circles. 
 06 -  Place 12 dough circles on baking sheet. Insert a lollipop stick halfway into the center of each base. 
 07 -  Spoon a heaping tablespoon of muffin batter onto each bottom circle, leaving a narrow border. Cover with remaining circles and press edges with a fork to seal. 
 08 -  Whisk egg with water, then brush the tops of each pie pop. Sprinkle lightly with coarse sugar for added texture. 
 09 -  Bake in preheated oven for 18 to 22 minutes, or until golden-brown and firm. Transfer to wire rack to cool completely before serving.
