Preheat oven to 400°F. Lightly grease a 12-cup muffin pan with the oil.
Whisk flour, baking powder, baking soda, sugar, and salt in a large bowl.
Stir buttermilk and yogurt together in a separate bowl until smooth.
Make a well in the dry ingredients. Pour in the buttermilk mixture and fold until almost combined.
Drizzle in the melted butter and gently mix just until no dry spots remain. Do not overwork.
Scoop batter into the muffin cups, filling each about three-quarters full.
Bake until tops are golden and a toothpick comes out clean, 12–15 minutes.
Brush hot rolls with the extra melted butter. Cool 5 minutes, then serve warm.
