Step 1

Preheat oven to 350 degrees F (175 degrees C).

Step 2

Heat a large skillet over medium-high heat. Add corned beef hash and break up larger chunks. Cook until browned on one side, 5 to 8 minutes. Turn and brown other side. Sprinkle with garlic powder and ground pepper. Transfer to a paper-towel-lined plate.

Step 3

Spread 1 dough sheet out onto lightly greased sheet of waxed paper. Spread half of the cream cheese over the dough sheet, leaving a 1/2-inch margin all around. Spoon half of the cooked corned beef hash evenly over cream cheese. Roll dough up into a log, starting at a long edge. Repeat steps to make another log with second dough sheet.

Step 4

Cut each roll into 1/2-inch thick slices (you should end up with 16 rolls total.) Place slices onto an ungreased baking sheet.

Step 5

Bake in the preheated oven until pinwheels are golden brown, 12 to 14 minutes. Serve immediately.
