Rhubarb Custard Cake

I had never heard of rhubarb custard cake until last week!Linda left a comment on my Strawberry Rhubarb Crisp recipe, sharing the recipe with me. I was immediately intrigued – it sounded delicious and so very, very easy. And it was full of whipping cream – so I knew it was healthy (wink, wink). She got the recipe from the Oregonian newspaperyears ago.

Pin it

It was not as “pretty” as I expected. But this is definitely NOT a cake you want to judge by it’s cover. All the rhubarb sunk to the bottom of the pan making a custard crust that was full of flavor. It was one of the most moist boxed cakes I’ve ever had. I would bring this to a church potluck in a heartbeat – people will oooh and ahhh.

I also think it would have looked fancier if I would have used a white cake mix instead of a vanilla cake mix. The white would have offset the pink rhubarb better, but the vanilla flavor was fantastic, too.

INGREDIENTS

1 box white cake mix (Duncan Hines or any kind that requires oil as an ingredient)

1/4 teaspoon freshly ground nutmeg (optional)

3 cups diced rhubarb, cut in 1/2-inch pieces

1 1/2 cups granulated sugar

1 pint whipping cream (2 cups)

HOW TO PREPARE

1.) Preheat the oven to whatever temperature is required by the boxed cake.

2.) Prepare the cake as it’s directed on the package. Add nutmeg to batter. Pour batter into an 11-by-15-inch glass baking pan (a 9-by-13-inch pan won’t work unless the pan is very deep; add five (5) minutes or so to the cooking time.) If you are using a metal plan increase temp 25 degrees.

Pin it.

3.) Right before you put the cake in the oven, toss the rhubarb and sugar together. Sprinkle the sugared rhubarb over the cake batter.

Pin it.

4.) Then you drizzle the entire pint of whipping cream over the batter and fruit; do not mix it in.

5.) Bake 35 minutes or until the cake top turns a light golden brown and begins to leave the sides of the pan. If you stick a wooden toothpick into the middle of the cupcake and it comes out clean, then it’s done.
