Try this creamy cookie dough frosting recipe.
A dense, sugary emulsion of aerated butter and brown sugar yields a rich spread that mimics raw confection textures while remaining structurally stable enough for piping. The high ratio of fat to liquid means temperature control dictates success. Butter must reach 65 degrees Fahrenheit before mixing to trap air bubbles effectively during the initial creaming phase. If the butter is too warm, the emulsion breaks and the mixture separates into a greasy slurry.
Incorporating dry all-purpose flour directly into a fat-and-sugar base creates a distinct mouthfeel, though raw grain carries microbiological considerations that standard baking eliminates. Brown sugar contains molasses, which introduces mild acidity. This acid reacts with dairy proteins and salt to deepen the butterscotch notes without requiring heat. When adding milk one tablespoon at a time on low speed, the liquid hydrates the starch granules in the flour gradually, preventing lumps from forming in the thick matrix. Miniature chocolate chips are folded in by hand at the final stage to prevent the mixer blades from fracturing the pieces and smearing cocoa streaks through the pale base. Batches scale linearly; halving the quantities requires a smaller mixing bowl to maintain paddle contact with the butter.
