This rhubarb polenta cake has a delicious tartness that shines against the moist, pleasantly crumbly, and grainy texture of polenta.

How is it that it’s June already?!! May was an intense month for me with photography project deadlines, being on our local TV channel (I’ll share more in another post), and traveling to the Bay Area for a friend’s wedding. Work and traveling left me mentally exhausted so I took some time off to recharge. I’m back and excited to post my first recipe for June, a rhubarb polenta cake that I have been waiting for two years to share. Yes, you read that right! TWO years!

Two years ago I grew rhubarb from seeds and they flourished and survived the blazing summer heat of San Diego. Thank you garden god! We couldn’t eat them fast enough. They went into many crumbles, pies, cakes, and ice cream. Then came baby Dillon, a period of adjustment to life with a toddler and a baby (still adjusting by the way), and a hiatus from blogging. I didn’t want another year to go by and not share this recipe with you.

This rhubarb polenta cake is a family favorite. It’s a simple cake that heralds spring. The tartness of rhubarb shines against the moist, pleasantly crumbly, and grainy texture of polenta. Vu is all about chocolate cakes but this particular one he loves, especially warm from the oven with vanilla ice cream. It’s such a cliche but we enjoy a lot of our baked goods with vanilla ice cream. If there’s any leftovers, I reheat it the next day for a minute in the oven and enjoy it with a cup of tea.

I do have to warn you that this rhubarb polenta cake is not for the faint of heart. The tartness of rhubarb does scare some people. If you’re not keen on rhubarb, you can always replace half of the rhubarb with strawberries and it will be as delicious. When I bring it to work, there are two camps--people who grew up with rhubarb and have fond memories of something their grandmas and moms made and will demolish this in seconds. But the other group doesn’t want to to eat a veggie cake. Rhubarb is a vegetable after all. If you like rhubarb and polenta, this cake is for you!

Hi Ed! I'm not sure why all the rhubarb sank to the bottom. When I find more rhubarb, I'll bake it again and let you know if I find any issues. Thank you for the feedback!
