Rhubarb Custard Cake Recipe

Rhubarb custard cake. A vintage cake recipe, from Cheap Recipe Blog. Repin to save!

I recently spent a week back home in rural Minnesota visiting my family. It was just perfect. The kind of week that makes me question living in a city. Here’s how we spent our time:

  • We took late night rides in my mom’s convertible
  • We visited some family friends who operate a flower farm (check out the beautiful bouquet pictured below!)
  • We enjoyed numerous fireworks displays from across the town’s lake
  • We enjoyed a campfire, s’mores, and good conversation with friends of my parents
  • We enjoyed a variety of activities during my home town’s 4th of July celebration (a parade, a classic car show, a community talent show, and a band concert in the park)

And needless to say, we all enjoyed a lot of great food.

One day, I accompanied my mom to Ladies Aid, a monthly Bible study attended by about 15 women from my home church. After the meeting, the hostess served a delicious rhubarb custard cake. By the time we were done eating, about half the group had jotted down the recipe, and a few committed to making it later in the evening.

I just love how inspiring a good recipe can be.

I made the cake the next day. My mom and I picked a bunch of rhubarb from our neighbor’s yard (don’t worry – we had permission!) so this cake didn’t cost much to make.

With the addition of sugar, rhubarb, and cream to the batter, this cake turns out moist and custardy. It’s one of those cakes that looks more difficult to make than it actually is. We need more cakes like that, don’t you agree?

    I wish I had a slice right now, it’s so dreamy! No rhubarb by our neighbors, I’ll have to buy it to experiment this custard cake…
