Combine the butter, shortening, brown sugar, and granulated sugar in a large mixing bowl. Mix until fluffy.

Add the eggs and vanilla and beat again until combined.

Sift in the flour, baking powder, and salt to the wet ingredients. Use a rubber spatula to fold in the dry ingredients until everything is incorporated.

Fold in the chocolate chips.

Chill the dough in the fridge for 3 hours.

Prepare a baking sheet with parchment paper and preheat the oven to 350 degrees.

Use a tablespoon to scoop the dough, roll the dough between your hands, and then place them 2” apart on the prepared baking sheet.

Bake for 14-15 minutes or until the edges of the cookies have firmed and are golden brown.

Transfer to a wire rack to cool.

Let the cookies cool completely before serving. They will become crispy as they cool just like the Famous Amos cookies.
