Mix together in a medium bowl the 2 ¾ cups flour, baking powder, salt, pumpkin pie spice, and cardamom. Set aside.
In a large bowl, cream together the butter and powdered sugar until fluffy, for about 2 minutes.
In a small bowl, whisk the eggs (1 whole egg, 1 egg yolk) and vanilla together, and then add it to the creamed butter mixture. Beat on high for 2-3 minutes.
Slowly add in the flour mixture to the dry ingredients, mixing on slow, until you have sticky and tacky dough.
TIP: If the dough is too sticky, you can add a tiny bit more flour. Too much flour will make harder, denser cookies.
Form the dough into a ball and allow to rest for 5 minutes while you preheat the oven to 400ºF and line baking sheets with parchment paper.
Cut the dough into 4 pieces.
Roll each piece of dough to 1/4” thickness on a lightly floured surface. TIP: You can use four or powdered sugar for rolling the dough to prevent it from sticking.
Using a cookie cutter (pumpkin shaped or any fall or Halloween shaped cookie cutters), cut the dough into desired shapes.
Transfer the pumpkin shaped dough onto the baking sheets.
Keep re-rolling the dough until you’ve used it up.
Depending on the size of the cookie cutter, bake the cookies anywhere from 4-7 minutes, until they are puffy, and edges barely start to brown. Too brown of cookies will be dry and crunchy.
Remove from the oven for 5 minutes before transferring to wire rack.
To make the frosting, in a medium bowl add the powdered sugar, pumpkin pie spice, water, and maple syrup. Whisk together.
Decorate or frost the cookies when they are cool.
Notes
You can freeze the cookies before frosting for up to 3 months.
