The recipe was nice and simple. I added some extra sugar too. The only recommendation is to lower the cooking temp because at 10 minutes they were already starting to burn at 425°F. I would recommend more the 350°F range and about 20 minutes of baking time.

I made this recipe but used a half of a can of cherry pie filling/topping in the batter. And used the remaining cherry filling to top each muffin. It made the muffins sweeter without adding more sugar directly :)
