Preheat the oven to 375F.
Line seven holes of a muffin pan with paper cups.
Heat the butter in a pan. Add the chopped onion and onion leaves. Cook gently until softened, about five minutes.
Meanwhile, in a bowl, stir together the flour, crumbled feta cheese, baking powder, baking soda and salt.
In another bowl, beat the egg and cream together.
Take the onion mixture off the pan, and quickly stir into the flour mixture. Pour in the egg and cream mixture, fold just until the batter comes together.
Pour into the prepared muffin pan. Bake at 375F for about 25 minutes.
Cool in the pan for about five minutes then transfer to a rack (just enough time for you to give the kitchen a final clean-up).
And that’s it. Have a wonderful breakfast.
