Delicious, and easy! Done in about 30-35 minutes, from start to finish. My friends & family's favorite muffins! Yields 24, and supposed to serve 24, but who can eat just one? REVISION: I have changed the recipe slightly, 2 cups sour cream, 2 1/2 cups flour, everything else the same -- DELISH! These are best right from the oven, but if you eat them the next day, then they are heavier, and less cake-y, more dense and moist. ANYTIME is a good time for these, I have gotten my friends hooked,lol!
