Sweet and Easy Rhubarb Cake Recipe

This post may contain affiliate links. Please read my Disclosure and Privacy Policy.

I love rhubarb cake and this recipe has a special place in my heart. Growing up my grandparents would always bring a paper bag of goodies with them every time they visited. While it wasn’t anything expensive, I would get excited to see what they brought in their bag.  My favorite things included packs of gum, my grandpa’s homemade maple syrup and fresh rhubarb. Just thinking about that makes me a little sad.

Isn’t it always simple memories you miss most?

Because we always seemed to have an endless supply of rhubarb when it was in season, my mom had several rhubarb cake recipes in which to use this tart but wonderful fruit like vegetable. I actually looked it up and while it is technically a vegetable it is regulated in the US as though it were a fruit. You learn something new every day.

  1. I just had this great cake last Sunday. However, it was not served “upside down” and
    your directions don’t say how to invert the cake. Do you invert each piece as you
    remove it from the pan, or do you turn the entire panful upside down first?

    1. Sorry about that! This was hand written on a recipe card and passed down so the instructions were rather brief. I’ve update the instructions to be more clear!

    I always make this cake when my supply is growing. Today I used rhubarb and raspberries at about a 2 to 1 ratio with rhubarb in the 2 ratio. Oh my it was good. And I have found no fruit that mixed with rhubarb doesn’t make a fine pie

  4. I’ve made this same recipe for years only I don’t turn it over I cool completely and top with cream cheese frosting. Family loves it. It’s a favorite.
