This has to be the best cobbler I have ever eaten...
I have made this twice and then tried it with peaches...with the peach cobbler, substituted 1/4 cup of cornstarch for 1/2 cup of flour... you must try this...
I did spray the skillet with a little Pam and then wiped with a paper towel...so it wouldn't me so greasy
