Preheat oven to 400°F. Combine melted butter, cayenne hot sauce and chili powder; toss with pierogies.
Coat a baking sheet with non-stick cooking spray and spread pierogies evenly on the baking sheet.
Bake for 16 to 18 minutes, or until pierogies are browned. For best results, turn over halfway through bake time.
Serve with blue cheese or ranch dressing, carrots and celery.
Alternate Preparation - Deep fry pierogies in 350°F oil for 3 minutes or until golden brown. Toss with cayenne hot sauce mixture.
