Old-fashioned brown sugar fudge—often called penuche—is a classic, nostalgic confection known for its warm caramel-like flavor and delicate, melt-in-your-mouth texture. Old-fashioned brown sugar fudge tastes like pure comfort—sweet but not cloying, rich but not heavy. Its flavor evokes heirloom recipes, holiday kitchens, and small-town sweet shops. The blend of brown sugar, butter, and vanilla creates a timeless treat that’s both simple and luxurious.
