I doubled the recipe using white whole wheat instead of the whole wheat (it was all I had) and made 12 with fig jam and 12 with sour cherry. I have only tried the fig so far and are incredibly delicious. They also look beautiful.
I did notice the batter was a bit thinner than normal muffin batter, but that means they turn out light and fluffy.
I will definitely make these again. Would make great gifts for the holidays.
