Can whipped butter be used for fat in a cake?

It's not ideal to use whipped butter directly in a cake batter. Here's why:

* Structure: Whipped butter contains air, which will make your cake rise unevenly and possibly create large holes in the texture.

* Stability: Whipped butter is less stable than regular butter, and it can deflate during baking, leading to a denser cake.

* Consistency: The lightness of whipped butter can make it difficult to incorporate into the batter properly, resulting in an uneven mixture.

However, there are ways to use whipped butter in baking, but not for cakes:

* Frosting: Whipped butter is excellent for making fluffy, light frosting.

* Spreads: It's a delicious and airy spread for toast or muffins.

* Cookies: You can sometimes substitute whipped butter for regular butter in cookies, but you'll need to adjust the recipe accordingly.

For cakes, always use regular, unsalted butter for the best results.
