Preheat your oven to 375°F (190°C).
In a large bowl, whisk together the flour, baking powder, salt, and sugar.
Stir in the buttermilk until just combined. Don’t overmix—it’s okay if it’s a little lumpy.
Melt the butter in a microwave-safe bowl. Add the minced garlic and parsley (if using) to the butter.
Pour half of the butter mixture into a greased 9-inch round baking dish.
Scoop the dough over the melted butter and gently spread it into an even layer.
Pour the remaining garlic butter over the top of the dough.
Use a knife to lightly score the top into 12 sections, which makes it easier to separate the rolls after baking.
Bake for 25 minutes, or until the top is golden brown and a toothpick comes out clean.
Let them cool for 5 minutes before diving in—if you can wait that long!
