Alternatives for vanilla yogurt in muffin recipe?

[aperson]

I have some sour cream, and i was thinking maybe putting some sour cream and vanilla extract... would that work? i do not have plain yogurt either

also if i can add sour cream and vanilla extract, how much do you think is a good amount?

it is a blueberry and lemon muffin recipe:

2.5 cups flour
1/2cup and 2 tablespoons sugar
2.5 teaspoons baking powder
.5 teaspoon baking powder

1/2 teaspoon salt
2 eggs
8 oz vanilla yogurt
1.25 teaspoon fresh lemon peel
1.25 cups blueberries

1 cup apple sauce

In this case you can and I would use one teaspoon of vanilla extract. It won't taste exactly like the recipe was designed but who knows it could be better. It's experimental baking and there is nothing wrong with that.
