Old Fashioned Rhubarb Cake with Cinnamon Sauce

It’s hard to imagine life before Pinterest. Chances are high that you found this recipe because of Pinterest!

Then came Pinterest. Talk about a game changer. I didn’t have to print off recipes anymore! I think I was more excited about not having to 3-hole punch stacks of paper. HA!

But thankfully I hang onto my trusty binder, because as pre-historic as it sounds I like being able to go to my post-it note tabs and find what I am looking for right away instead of trying to scroll through my bazillions of saved recipes on Pinterest.

This recipe for Rhubarb Cake with Cinnamon Icing is one of my all-time favorites. I didn’t find it online; it was given to me years ago by someone I used to work with. So when I want to make it for rhubarb season I know exactly where to find it – in my trusty, tattered, and worn binder that has served me very well over the years!

It’s one of my favorite recipes because even if you don’t like rhubarb you will love this cake! It’s so moist it just melts in your mouth. If you love rhubarb, then you will like this Rhubarb Crisp , Fresh Rhubarb Pie , and Rhubarb Breakfast Cake!

How to Make Rhubarb Cake with Cinnamon Icing

Preheat oven to 350 degrees. Spray a 9 x 13 pan with non-stick spray and set aside.

Chop enough rhubarb to make 3 cups. Set aside.

In a medium size bowl, beat together 1 cup sugar, 1/3 cup softened butter, and 1 egg until smooth.

In a separate bowl, whisk together 1 3/4 cup flour, 1/2 tsp salt, and 1 tsp baking soda. Then whisk in 3/4 cup milk. Pour in sugar mixture and beat until well mixed.

Fold in 3 cups chopped rhubarb.

Pour and spread batter into prepared pan. Then sprinkle 1 cup brown sugar and 1 cup chopped pecans evenly over the top.

Bake for 45 minutes.

About 5 minutes before the time is up, combine 1 cup powdered sugar, 2 tbsp milk, 2 tbsp melted butter, and 1 tsp cinnamon. Mix together until smooth.

Pour over warm cake until covered.
