As summer draws to a close, it’s time to pause one last time and acknowledge the plum. All summer long, they have been a staple in my weekly CSA box and I have been thinking I must make an upside-down cake.
This one is particularly easy. I made it before work this morning while also packing lunches and preparing breakfast for my two kids. Slice the fruit and mix the batter. That was about it.
The great news is the cake come out light and fluffy and the plums work their own magic so the end result is delicious. I’ve added twice the normal amount of vanilla in this recipe which made the flavor of the cake really pop.
- 7 Tablespoons butter, divided
- ⅔ cup sugar, divided
- 4 plums, thinly sliced - choose plums that are not overly ripe
- 1 egg
- 1 cup flour
- ¼ teaspoon salt
- 1 tsp baking powder
- ½ cup milk
- 2 teaspoons vanilla extract
- Preheat the oven to 350˚F.
- Place one tablespoon of butter in a circular pie pan and melt in the oven for a couple of minutes.
- Meanwhile, cream the butter with the remaining sugar. Add the egg and beat until smooth.
- Remove the pan from the oven and sprinkle ⅓ cup of sugar evenly around the bottom.
- Arrange the plum slices in neat, concentric circles on top of the butter/sugar.
- In a separate bowl, mix together the flour, salt, and baking powder.
- Add the dry ingredients to the cream mixture in batches, alternating with the milk until mixed thoroughly.
- Add in the vanilla and mix until batter is smooth. If the batter is too thick, mix in another tablespoon of milk.
- Spread the batter evenly on top of the plums, working it all the way out to the edge of the pan.
- Bake for 25-30 minutes or until golden brown. A knife inserted in the cake should come out clean.
- Remove from the oven and invert onto a plate immediately.
- Serve warm.
