Add the potatoes to a large pot of water. Bring to a boil, cooking for 10-15 minutes until fork tender. Drain the potatoes and add to a large bowl.
1½ pounds Russet potatoes
Add in the cheese, salt, onion powder, and pepper. Mash until smooth.
1 cup freshly shredded cheddar cheese
, 2½ teaspoons kosher salt, ¼ teaspoon onion powder, ½ teaspoon ground black pepper
Roll out the dough on a floured surface to a ⅛-inch thickness.
Use a round biscuit cutter or a glass about 3 inches wide to cut out circles. Gather excess dough into a ball, roll it out, and cut out more circles.
Spoon about 1 tablespoon of filling onto the middle of each round.
Dip your finger into water and run it around the edge of half of the round. Fold the other half of the round over the filling and pinch the edges to seal. Repeat for the rest of the dough and filling.
