If you like cake doughnuts, you're going to love this recipe! These muffins taste just like a good cake doughnut. I think my kids each ate three of them within a few hours this morning. My husband said he liked my muffins, too, but based on the smirk on his face, I think he meant something other than these.

2 3/4 c flour
1 c sugar
1/4 c corn starch
1 T baking powder
1 t salt (omit if you use salted butter)
1/2 t ground nutmeg
1 c buttermilk
8 T butter, melted
2 large eggs, plus 1 egg yolk
1 c sugar
2 t cinnamon
8 T melted butter
Preheat the oven to 400 degrees. Grease the muffin tin very well.
In a large bowl, whisk together the flour, sugar, corn starch, baking powder, salt, and nutmeg. In a separate bowl, combine the melted butter, buttermilk, eggs, and egg yolk. Make a large well in the dry ingredients. Pour in the wet ingredients. Use a rubber spatula to combine the wet and dry ingredients. Mix until no flour remains.
Divide batter into the 12 cups. The batter will be thick, and you'll fill them to about 3/4 full. Use all of the batter.
Bake for 19-22 minutes or until a toothpick inserted into the middle comes out clean. Let them cool in the muffin tins for 5 minutes.
Pour them onto a clean counter.
Combine the sugar and cinnamon in a bowl. Working on one doughnut at a time, brush it completely with butter. Roll it in cinnamon sugar. Repeat with all doughnut muffins.
Let rest for another 5-10 minutes.
