Preheat oven to 375 degrees Fahrenheit. Line 2 cookie sheets with parchment paper and set aside.
In a medium mixing bowl, whisk together the flour, baking powder, and salt. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment beat butter and coconut oil until creamy.
Add sugars, beating until light and fluffy, 3-4 minutes.
Beat in eggs, one at a time, waiting for the first to be fully incorporated before adding the next.
Stir in the vanilla.
Gradually add the flour mixture, beating until just incorporated.
Using a #60 cookie scoop (2-tsp), portion out dough onto the prepared baking sheets, leaving 2 inches between each dough ball.
Bake 9-11 minutes, or until the edges have browned.
Leave on cookie sheet for 2 minutes, then remove to wire racks to finish cooling.
