Preheat oven to 350 degrees F. Prepare a muffin tin by spraying the muffin cups with a baking spray that contains flour or use paper liners.
In a medium size bowl whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, ginger, and salt.
1 3/4 cups All-purpose flour, 1 tsp Baking powder, 1/2 tsp Baking soda, 2 tsp Ground cinnamon, 1/2 tsp Ground nutmeg, 1/4 tsp Ground ginger, 1/2 tsp Kosher salt
In a large bowl whisk together the eggs, oil, sweet potato puree, and sugars until smooth and combined well. Fold in the flour mixture just until combined.
2 cups Sweet potato puree, 2 large Eggs, 1/3 cup Vegetable oil, 3/4 cup Granulated sugar, 1/2 cup Dark brown sugar
Divide the muffin batter among the cups evenly. They should each be about 3/4 full. Bake for 25-28 minutes or until a toothpick inserted in the center comes out clean.
Cool in the muffin pan for 5 minutes, then transfer the muffins from the pan to a wire rack to cool to warm or completely.
