Preheat your oven to 450°F (230°C). Pour the melted butter into a baking dish, making sure it coats the bottom evenly. This step is key to achieving that rich, buttery base.

In a large bowl, combine flour, baking powder, sugar, and salt. Stir everything together until evenly mixed. This ensures the biscuits rise properly and taste balanced.

Pour in the buttermilk and gently mix until a thick batter forms. Avoid overmixing, as it can make the biscuits dense instead of soft and fluffy.

Add the diced ham and freshly grated cheese to the batter. Stir just enough to distribute them evenly throughout the mixture without overworking the dough.

Carefully spread the batter over the melted butter in the baking dish. Use a spatula to gently even it out without mixing it into the butter layer.

Using a knife, lightly score the dough into square portions. This makes it easier to separate the biscuits after baking and helps them cook evenly.

Place the dish in the oven and bake for 25–30 minutes. The top should turn golden brown, and the edges will be crispy from the butter.

Allow the biscuits to cool slightly before serving. This helps them set and makes cutting easier while keeping them soft inside.
