Baking mixes are pre-packaged combinations of dry ingredients designed to simplify the baking process. They typically include flour, sugar, leavening agents, and flavorings, allowing home bakers to create a variety of baked goods like cakes, cookies, and muffins with minimal effort. Just add wet ingredients, such as eggs and milk, and follow the instructions for quick and easy results. These mixes are popular for their convenience and consistency, making them ideal for both novice and experienced bakers. Brands like Betty Crocker and Duncan Hines offer a wide range of options, catering to different tastes and dietary needs, including gluten-free varieties.
