Grate the cheese on the smallest hole of a box grater. You should have about 1 1/2 cups loosely packed cheese.
In a medium bowl, whisk together the flour and baking powder then stir in the grated cheese.
Add the melted butter and stir just until a cohesive dough forms.
Lightly flour your work surface.
Transfer the dough onto your work surface, gather it into a ball and knead it a few times until smooth. Roll the dough into a log with a 2-inch diameter.
Wrap the dough log securely in plastic wrap and refrigerate it for 30 minutes.
Add the Everything bagel seasoning to a shallow bowl.
Unwrap the dough and roll it in the Everything seasoning, pressing it to adhere. Re-wrap the dough log in plastic wrap and refrigerate it for a minimum of 1 hour and up to overnight.
When ready to bake, preheat the oven to 350°F. Line two baking sheets with parchment paper.
Remove the dough log from the fridge and using a sharp knife, slice it into 1/4-inch-thick rounds. Arrange the rounds at least 2 inches apart on the baking sheets.
Bake the cookies until pale golden and set in the center, 12 to 15 minutes. Remove them from the oven and let them cool for 5 minutes on the baking sheets before transferring them to a wrack to cool completely then serve.
