Author Notes

This recipe has been in my family a long time. It comes from my Great-Grandmother Mildred Lohmann who had a gigantic rhubarb plant in her backyard. The tangy rhubarb perfectly offsets an otherwise fluffy and sweet coffeecake batter that is then sprinkled with cinnamon sugar. —Gibson2011

What You'll Need
  • 1/2 cup unsalted butter
  • 1 egg
  • 3/4 cup brown sugar
  • 2 cups flour
  • 1 1/2 cups rhubarb, sliced into 1" slices (or smaller, if a large stalk)
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup buttermilk
  • 1 teaspoon vanilla extract
  • 1/4 cup sugar
  • 1 tablespoon cinnamon
  1. Heat oven to 350. Cream brown sugar and butter till fluffy. Add egg and combine. Add flour, baking soda and salt, alternating with the buttermilk, stirring to combine. Add vanilla and rhubarb.
  2. Spread in greased and floured 9x13" pan. Sprinkle with 1/4 C of white sugar and 1 tsp cinnamon. Bake for 30 minutes or until a tester comes out clean.

Update on my previous review. The baking time (which I guessed at) was too long as it was very dry. I took it to work where no one ate it and that's saying something! I am throwing the rest out and will not try it again. Must keep looking for a good rhubarb recipe. This was unfortunate as Food52 usually has such good recipes.

Aghhh! I just put it in the oven....no where does it say how long to bake!

I baked it about 35 mins & it was done. Maybe a bit overdone. Not very sweet but I never used that last 1/4 cup sugar as it didn't say where or when to add. Not a very well written recipe.

Must be a serious typo in this recipe. I started making it to find the recipe called for 1 cup of baking soda and 1/2 c salt. Surely this is incorrect? I changed it to 1 t soda and 1/2 t salt you might want to do the same if attempting this recipe or you will end up with a very salty cake that will collapse.
