If you're looking for a substitute for milk in baking a cake and you don't have yogurt or sour cream available, there are a few alternatives you can consider. Here are a few options:
Non-Dairy Milk: Use a non-dairy milk such as almond milk, soy milk, oat milk, or coconut milk as a substitute for regular milk. These alternatives should work well in most cake recipes. Choose an unsweetened variety for best results.
Buttermilk Substitute: If you don't have regular milk but have vinegar or lemon juice on hand, you can create a buttermilk substitute. Simply mix 1 cup of non-dairy milk with 1 tablespoon of vinegar or lemon juice. Let it sit for a few minutes until it curdles slightly before using it in the recipe.
Water: In some cases, you can also use water as a replacement for milk. However, keep in mind that using water may affect the texture and richness of the cake. It's generally best to use this option if there are no other alternatives available.
Remember that the substitution may slightly alter the taste, texture, and moisture level of the final cake, but it should still be enjoyable. It's always a good idea to experiment and adjust the recipe as needed based on the substitute you choose.
