Preheat oven to 400 degrees Fahrenheit.Combine all dry ingredients in a small bowl, then add in wet ingredients and mix well.Melt butter in 1-cup (8 ounce) ramekin to coat inner surface. (You can also use olive oil or cooking spray, but I found that butter worked really well in this recipe to give the cake a yummy buttery crust).Bake at 400 degrees Fahrenheit for 20 minutes, then set oven to high broil for an additional 5 minutes.Use a knife to carefully pry the edges of the cake from the ramekin (easy as long as it was greased well!) and flip upside down into a dish.Top with preserves. Enjoy!
