I love pineapple but have never made this classic cake before, or any upside-down cake whatsoever. I made mini versions and a large one and they turned out quite nice. This is a fairly easy cake to make and it looks adorable.
Traditionally a cherry is placed into the center of the pineapple slices but I decided to replace it with a grape as I'm not the best friend of cherries. It turned out that the baking made the grapes taste like rhubarb, which was quite a funny twist.
As a guideline I used this recipe.
Pineapple slices in syrup
A few grapes
1tsp baking powder
1tsp vanilla extract
4tbsp pineapple syrup
For the topping whisk soft butter with sugar and brush it to the cake tin. Place the pineapples on it and grapes to the center of the pineapple rings.
Use only one pineapple per tin if you make the mini versions.
Whisk the cake base ingredients together and put it on the pineapples.
Bake for about 35 minutes at 180C and enjoy with coffee.
