Prepare the Savory Core
Boil & Mash: Boil the potatoes until tender. Peel and mash thoroughly while warm until completely smooth.
Season: Stir in the salt, black pepper, and chili flakes.
Cheese Center: Mix the shredded cheese into the warm mash for a uniform filling, or reserve it to place a pinch in the center of each ball for a "molten" core.
Mix and Knead the Dough
Activate: Combine warm milk and yeast in a large bowl. Add salt.
Knead: Gradually add flour and knead until a shaggy dough forms. Incorporate the softened butter and continue kneading for 5–7 minutes until smooth and elastic.
The First Rise
Proof: Cover the dough with a damp cloth in an oiled bowl. Let it rise in a warm spot for 40–60 minutes until doubled in size.
Shape the "Potatoes"
Portion: Punch down the dough and divide into 9 equal balls. Rest for 5 minutes.
Stuff: Flatten each ball, place a spoonful of potato-cheese filling in the center, and pinch the edges to seal.
Form: Roll the dough into an oblong, irregular shape to mimic a real potato.
Apply the "Soil" Illusion
Coat: Whisk the cocoa powder and 1 tablespoon of flour together. Roll each shaped bun in the mixture until fully covered in "dirt."
Add Realism: Place on a lined baking sheet. Use a skewer to poke 3–5 irregular "eyes" or dents into the surface.
The Bake
Cook: Bake in a preheated oven at 340°F (170°C) for 25 minutes.
Finish: The cocoa will set into a matte, dusty finish. Serve warm to maintain the soft, cloud-like interior.
