Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners, or generously grease the cups. Set aside. In a large mixing bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon. In another bowl, whisk together milk and PediaSure Grow & Gain Shake Mix Powder until well-blended. Add oil, sugar, egg, and pumpkin puree and mix until blended. Add pumpkin mixture to flour mixture and mix until just moistened. Fold in chocolate chips. Spoon batter into muffin cups, about 2/3 full. Bake 15 to 18 minutes, or until a wooden toothpick inserted into center comes out clean. Cool and dust muffins with confectioners’ sugar if using. Store muffins in an airtight container for one day, or place each muffin in an individual re-sealable plastic bag and freeze.
