Preheat the oven to 400 degrees Fahrenheit and spray a muffin tin with cooking spray.
Let the puff pastry sheets thaw at room temperature for 20 minutes, or until you can unroll them without tearing.
Use a rolling pin to roll out one sheet. Slice the sheet into 6 strips. Use a 2½” circle cookie cutter to punch circles out of the other puff pastry sheet
In a small bowl, whisk the egg.
In another small bowl, whisk together the sugar and cinnamon.
Brush the pastry strips and circles with the egg, then sprinkle with the cinnamon sugar.
Line the muffin tin walls with the puff pastry strips, then press the circles on the bottom of the lined tins. Bake for 19 minutes, or until golden brown. Let cool completely.
Scoop the softened Halo Top over the cooled puff pastry bowls. Serve immediately. Enjoy!
