I have a question about the recipe "Chocolate Bundt Cake" from KelseyTheNaptimeChef. Can I substitute buttermilk for sour milk?
I say yes. Typically you can exchange one for the other in recipes.
I have made bundt cakes before using sour milk and have not had a problem with the substitution...I say go for it.
I've made this recipe twice - both times with buttermilk. Came out great. (Really delicious cake, btw.)
I've made it with buttermilk, too. Really great cake. In case you didn't believe everyone else. :)
