Creating Spooky Skull Potatoes is a fun and engaging process. Follow these steps to prepare your frightfully delicious dish:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C).

2. Boil Potatoes: Peel and chop the potatoes into equal-sized chunks. Place them in a large pot of boiling salted water. Cook until tender, about 15-20 minutes.

3. Drain and Mash: Once cooked, drain the potatoes and return them to the pot. Add the butter, milk, garlic powder, onion powder, salt, and pepper. Mash until smooth and creamy.

4. Prepare for Skulls: If you have a skull-shaped mold, fill it with the mashed potato mixture. If not, simply shape the mashed potatoes into skulls on a baking sheet.

5. Add Cheese: Sprinkle the top of each skull with shredded cheddar cheese.

6. Bake: Place the filled molds or potato shapes into the preheated oven. Bake for 15-20 minutes or until the cheese is bubbling and golden brown.

7. Decorate: Once removed from the oven, use slices of black olives for the eyes and nose. Optionally, sprinkle chopped parsley for a touch of color.

8. Serve: Allow the skull potatoes to cool slightly before serving.
