Vanilla cupcakes recipe

These are by far the best vanilla cupcakes I ever baked. Brilliant recipe I would say! I thought I had the best recipe, but I have to admit that this is much much better and worth giving it a try! It so rich and moist.  I found the recipe from Food Network months ago but did not dare to give it a try. I changed the recipe a little bit ( I don't like it too sweet). Thanks to Allysa Torey, founder of  famous Magnolia Bakery!
