Buttermilk Baking Powder Biscuits

These biscuits are part of my husband's favorite breakfast (along with sausage and eggs). I always make them on Father's Day, Allen's birthday, and whenever I am about to make a large purchase.

I joke, I kid.

I replace the "buttermilk" (milk+vinegar) with kefir (Click here for my What is Kefir? post) for pretty much any recipe on this site that calls for buttermilk, because I always have kefir, and it tastes just as good and costs next to nothing when you brew it yourself.

These are extra yummy and flaky when I bake them in my deep-dish pizza stone.

Sourdough version:

I just make the biscuit dough like normal, then mix in my sourdough discard (it was a whole cup for the ones below--it adds a great sourdough flavor, but they still rise as fluffy as ever because I don't omit the baking powder.
