Generously grease 8 skull-shaped cavities in specialized pans with 1 tablespoon of softened butter to ensure easy release after baking.

In a large mixing bowl, combine 2 tablespoons softened butter (cut in pieces), all-purpose flour, egg, sugar, salt, and instant yeast. Pour in lukewarm water and blend thoroughly with a spoon or stand mixer fitted with a dough hook.

Knead dough by hand on a floured surface or with a mixer for 5–7 minutes until smooth and elastic. Cover with plastic wrap and allow to rise at room temperature until doubled in volume, approximately 1 to 2 hours.

Punch down dough and divide into 8 equal portions. Shape each piece to fit snugly into the greased skull pan cavities. Cover with plastic wrap and let rise until nearly doubled, about 1 hour. Meanwhile, preheat oven to 375°F.

Bake skull buns for 14–18 minutes, rotating halfway, until golden brown. For a lighter crust, remove at 14 minutes; for deeper color, bake up to 18 minutes. Immediately invert buns onto a wire rack to cool.

Melt remaining 2 tablespoons of butter and brush thoroughly over the tops of warm buns for a glossy finish. Allow to cool completely before slicing.

Divide ground beef into 8 even portions. Shape each into a skull using hands or a suitable mold, refrigerating shaped patties until ready to cook.

Season patties generously with salt and pepper just before cooking. Heat 1 teaspoon butter, lard, or oil over medium-high in a cast iron or nonstick skillet until shimmering. Cook 3 burgers at a time, about 3 minutes per side for medium-rare (135°F).

After flipping, top each burger with a slice of cheese and cover pan to melt the cheese thoroughly. Repeat process for remaining burgers.
