Place butter into the bottom of an 8" round baking pan and place into the cold oven.

Preheat oven to 350 and leave butter in the pan for about 5-7 minutes or until completely melted. Remove pan from oven and let oven preheat completely.

Break apart packed brown sugar and sprinkle on top of melted butter.

Add pineapple slices, keeping them in a single layer. Slice a few additional slices to fill the gaps in the pan and add the pineapple.

Follow by adding cherries and top with pecans. 

In a mixing bowl, add Bisquick and sugar together and mix well.

Add sugar, milk, egg, oil and vanilla and mix until combined well.

Pour on top of pineapples in pan and bake for 25-35 minutes or until a toothpick inserted in the center comes out clean. 

When cooking is complete, remove from pan and immediately place a serving plate upside down on your pan. Turn plate and pan over and place onto a flat surface.

Let stand for 2-3 minutes and carefully lift pan off to reveal the cake. Cool 15 minutes before serving warm, or cool completely before serving.
