Preheat oven to 350 degrees.
In a large bowl, combine flour, sugar, salt and baking powder.
In a one cup measuring cup, add a cracked egg and beat. To that, add 4 tbsp oil of choice, and mix. Finally, fill the rest of that one cup measuring cup with milk. Add to dry ingredients and mix well.
Add vanilla to batter and blend. Set aside.
In a 9 inch round baking pan, melt butter. I did so placing it in the oven while it heated. To that, I added the sugar, stirred it carefully, and returned it to the oven to stay warm.
Prepare your fruit by chopping it into smaller pieces. You should have approximately 2 to 3 cups. I simply used enough to cover the bottom of the pan.
Remove warm pan of butter and sugar from the oven, and add fruit on top.
Next, pour batter over fruit, and bake for 40 minutes at 350 degrees.
After removing from the oven, place a plate or platter over the top of the pan, and flip it over onto the plate. Do so shortly after removing it from the oven, or the sugar will harden, making it difficult to remove from the pan.
