Rhubarb Coffee Cake with Caramel Sauce

Growing up, this recipe was a favorite of mine. I couldn't wait for the rhubarb to ripen so Mom could bake this delicious coffee cake. Now this special recipe is part of my own collection. —Angie Fehr, Ottosen, Iowa

    I have a recipe like this from my grandma. Hers has walnuts in the topping so I added walnuts. Of course the caramel sauce makes it wonderful.

    I found this recipe a couple years ago and made it. It was the first recipe I had ever used rhubarb in. It was an instant hit. Last year, when I had rhubarb I could not find the recipe again. I was so disappointed! I tried some other recipes and they were not nearly as good. Glad I found this one again. I have to make 2 cakes because it goes so quickly in my large family. I highly recommend this. As others have said, it does not need the caramel but it makes even better.

    This was the best Rhubarb recipe I have made, or ate anywhere else. It is moist, has a lot of flavor, and very easy to make. I don't think it even needs the caramel sauce; it didn't get that far before my husband was in it. This recipe is good warm out of the oven but does not need to be warm in my estimation to taste perfect. My other recipes took more time and were definitely not near as good. I would definitely recommend this recipe; my other recipes went into File 13! Thinking about trying it with apples after rhubarb season is over. I wonder if the apples would be too moist?????

    Loved this even without caramel sauce, very moist. My rhubarb sunk to the bottom of cake, but thats ok, still excellent. Rich buttery taste with bits of rhubarb.
