I found this on line at the PA Farm Show site -
The cake was a first place winner - 2011 - by Sally Reinoehl - brava!!!
Preheat oven to 350 degrees - Generously grease a 13 x 9 pan
1 C Butter
1 C Brown Sugar (I used Dark)
2 Tlbs Light Corn Syrup
Place all these ingredients in a small saucepan. Heat till sugar is melted.
3 Eggs (room temp)
2 C Sugar
1 C Vegetable oil
1 C Sour Cream
2 tsp Vanilla
2 1/2 Flour
1/2 tsp Salt
1/2 tsp Baking Soda
2 tsp Baking Powder
In a large bowl beat eggs and sugar until thick and lemon coloured. Beat in oil, sour cream and vanilla. In another Bowl sift together dry ingredients. Add the sifted mix to the egg mixture; mix well.
Pour syrup into the prepared pan. Place 12 slices of pineapple over syrup (I used two cans that had 8 slices, 12 would have been better - I also placed cherries in the the holes of the pineapple) Pour batter over the pineapple slices. Bake for about 50 minutes - until done. Testing with a toothpick. I found that the cake browned quickly and the last 12 or so minutes I turned the temp down a bit, but that was probably my oven. Remove from oven and let rest for about 5 minutes. Flip onto plate and let cool completely. I let it sit for a little longer than 5 mins and the topping stuck a little - so 5 mins max for sitting before turning onto a plate!! If you didn't add the cherries before baking Sally recommends decorating the cake at this point.
This came together very fast and was very tasty.
