Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, whisk together flour, baking powder, ginger, cinnamon, nutmeg, and brown sugar.
In another bowl, whisk eggs and vanilla until smooth. Gradually combine with dry ingredients until just mixed; do not overmix.
Fold in chocolate chips gently.
Shape the dough into two logs (12 inches long by 3 inches wide) on the baking sheet.
Bake for 25-30 minutes until golden brown. Cool slightly before slicing diagonally into 1-inch pieces.
Arrange slices cut-side down on the baking sheet and bake again for another 10-15 minutes until crispy.
