Upside-down Rhubarb Cake

Upside-down cakes got a bad reputation in the States, and it is no wonder why, when most of the recipes for it call for “a box of yellow cake mix, canned pineapples in heavy syrup and artificially colored red maraschino cherries”…
Yet, upside-down cakes are wonderful when prepared properly, with fresh ingredients; the sugar and butter at the bottom caramelize lightly, blending nicely with the fruit, and with the cake batter on top. Add to this the fact that the cake is very easy to make, and you can’t help but wonder why on earth anyone would consider ruining this nice cake with all those horrid ingredients. So, here’s a chance to redeem the cakes’ bad reputation.

As I found beautiful rhubarb at the store, I’ve decided to use it for the fruit layer – and it turned out to be a great match. The color pops up and the tangy flavor is the perfect balance for the sweetness of the cake.
I’ve also decided to use dark brown sugar for the bottom (i.e. top), instead of the traditional white sugar. The brown sugar adds another layer of flavor and creates an interesting contrast with the pale batter. Sprinkling spices over the sugar layer, added a wonderful aroma to the cake. The result was a cake I will most likely make again soo, and I’m sure you will too, once you’ll try it.

Notes:
* White or golden sugar, can be used instead for the dark brown sugar I’ve used here.
* If you can’t find rhubarb, red plums, or any firm tart fruits, will work as well.

Makes: 6
Prep time: 20 minutes
Baking time: 35 minutes

Ingredients:
For the rhubarb layer:
1/3 stick (40 grams) soft butter
¾ cup dark brown sugar
¼ tsp cinnamon powder
¼ tsp ginger powder
2 rhubarb stalks (see notes)
For the batter:
2/3 stick (75 grams) soft butter
¾ cup white sugar
2 L eggs, at room temperature
1 cup milk, at room temperature
1 tsp vanilla
1½ cups flour
2 tsp baking powder
Dash salt

1. Preheat the oven to 350F (175C).
2. The fruit layer: spread the butter over the bottom of a 9½” (24cm) deep cake pan. Sprinkle the brown sugar on top, avoiding about ¼” (½ cm) from the sides (this will help in releasing the cake from the pan later on). Sprinkle the spices on top. Cut the rhubarb into 1” (2 cm) pieces. Arrange in circles on top of the sugar. Keep in the fridge until the batter is ready.

3. The batter: place the butter and white sugar in a mixer bowl, fitted with the mixing hook. Mix until combined. Add the eggs and mix again.

Add the milk and mix lightly (the mixture will seem “broken”- don’t be alarmed, it’s fine). Add the vanilla, flour, baking powder and salt. Mix to a smooth batter, scraping the sides of the bowl once.

4. Pour the batter over the rhubarb layer, from the center out, again avoiding the sides.

5. Bake for 35 minutes,  or until the cake is golden and a toothpick inserted in the center comes out clean. Take the pan out of the oven and let it stand for 1-2 minutes in the pan.

6. Place a plate (the size of the pan or bigger) on top of the pan. Using oven mitts (remember, the pan is still hot!) hold both the plate and pan together, and turn the pan upside down over the plate. Place on a work surface and carefully remove the pan.

7. If there is still caramelized sugar at the bottom of the pan, scrape it gently and add to the top of the cake. Let cool to room temperature before cutting.
