Start by slicing your buns in half horizontally with a sharp bread knife, keeping them as intact as possible.
In a small saucepan, gently melt the butter over low heat until it just turns to a liquid and begins to shimmer, filling the air with a rich, inviting aroma.
Stir the sugar and ground cardamom into the melted butter until well combined and fragrant—this mixture should look glossy and aromatic.
Use a pastry brush or the back of a spoon to generously coat the cut sides of each bun with the warm butter mixture, soaking up every bit for maximum flavor.
Preheat a non-stick skillet or griddle over medium-low heat until warm, then carefully place the buns cut side down on the surface.
Toast the buns for about 2-3 minutes until the cut sides turn golden brown and develop a slight crisp, releasing a warm, buttery aroma.
Flip the buns gently using a spatula and toast the other side for 1-2 minutes, just enough to warm through and add a light golden hue.
If the buns seem dry during toasting, splash a tiny bit of warm milk around the edges to keep them moist and tender.
Remove the buns from the skillet and let them sit for a minute to absorb all the fragrant butter and sugar glaze.
Optionally, sprinkle with crushed pistachios or a dash of cinnamon for extra flavor and visual appeal.
Serve the Bun Maska immediately while warm, enjoying the soft, buttery, and slightly crisp textures with the irresistible aroma filling the room.
