Apple Upside Down Cake

This is one of my mother's favorite cakes... and so made it for her homecoming ...:)
I have made this cake several times... and each time it has a different ending. Sometimes the apple pieces would 'come up' into the cake batter as it cooks,,as it happened this time, or it would stay at the bottom and get caramelized with the toffee layer. Either way you get a nice, sticky, toffee topped vanilla cake.. :D

For the vanilla cake the recipe is here

 Ingredients for apple layer

2 green apples sliced thin (can also use red..but the tartness of the green ones are perfect)
4 tablespoons (1/4 cup) (55 grams) unsalted butter, cut in small pieces
3/4 cup  brown sugar
a tablespoon of fresh cream (optional)

a pinch or two cinnamon powder.. to taste

Preheat oven to 350 degrees F (177 degrees C) and place rack in the center of the oven. Butter and line with baking paper, a 9 inch (23 cm) round cake pan with three inch (7.5 cm) sides.

Mix all the ingredients except apples and pour into the prepared pan (9 inch)

                                                          Layer the apple slices.

Pour the vanilla cake batter over the slices and bake.

It will take longer than the plain cake..About 30 mins. more. It is ready when a toothpick inserted comes out clean.

  Allow to cool and then flip it onto a plate to bring the apple layer up.

Slice and serve.... :)
