Heat oven to 350 and line a couple cookie sheets with parchment paper.
Cream butter, sugar and brown sugar in a stand mixer or by hand until light and fluffy.
Add the eggs and vanilla and beat until fluffy again.
In a bowl, whisk the flour, baking powder, baking soda, graham crackers, and salt.
Add dry ingredients to the butter and mix just until combined.
Measure out 1/2 cup portions and roll into a ball, then flatten to 1 inch thick. I could fit 4 per cookie sheet.
Bake 10-13 minutes until just turning golden on the edges.
