What can be used as a substitute for margarine in cake?

There are several substitutes for margarine in cake, depending on what you're looking for:

For a healthier option:

* Unsalted butter: This is the most common substitute and will give the cake a richer flavor. Use the same amount of butter as the recipe calls for margarine.

* Olive oil: For a slightly lighter cake, substitute 1/3 cup olive oil for every 1 cup of margarine.

* Applesauce: Unsweetened applesauce can replace 1/2 cup of margarine per cup of margarine called for in the recipe. It will make the cake slightly denser and moister.

* Avocado: Mashed avocado can be used as a substitute for butter or margarine, providing a rich, creamy texture. Use 1/4 cup of mashed avocado for every 1/4 cup of butter or margarine in the recipe.

For a vegan option:

* Vegan butter: There are many brands of vegan butter available that work well in baking.

* Coconut oil: Substitute coconut oil for margarine, but be aware it will add a subtle coconut flavor. Use a 1:1 ratio.

* Vegetable shortening: This is a good option if you want a cake that is light and fluffy. Use a 1:1 ratio.

For a buttery flavor:

* Butter: This is a good option if you want a cake with a rich, buttery flavor. Use the same amount of butter as the recipe calls for margarine.

Other things to consider:

* Type of cake: Some cakes, like pound cakes, benefit from the solid fat content of margarine. If you are substituting with something else, you may need to adjust the amount of liquid in the recipe.

* Flavor: Some substitutes, like olive oil or coconut oil, will add a subtle flavor to the cake.

Ultimately, the best substitute for margarine in cake will depend on your individual preferences and the specific recipe you are using. Experiment with different options to find what works best for you.
