With a few adjustments these are 5 stars! I replaced the oil with melted butter, reduced sugar by 1/4 cup, 1 cup of oj in place of the buttermilk and left out the vanilla! These are great for school and work lunches. I got 24 mini muffins out of this recipe! Next time I will add some raisins and orange zest! Great starter recipe, thanks for sharing! Forgot to mention that I left the topping off all together. Makes them a bit healthier!
