Rhubarb Grunt: A Classic Americana Dessert

I really need to get something off my chest.  I love the English language.  I love waxing poetic and tweaking word use to convey an untraditional meaning of a word.  There are some words however that I just don’t like.  I don’t like to say them.  I don’t like how they sound.  I don’t like what they mentally conjure for me.  This dislike diverts me from a freewheeling lexicon to a bit of a dead stop.  I really don’t like these words in my mouth let alone coming out of it.  I guess that makes me a selective ‘word prude’.

One of these words is in the title of this recipe.  And it’s not rhubarb.  I found myself swallowing the word when telling my family about the dessert I made.  They looked quizzically not able to understand my answer.  I’d respond with ‘it’s a rhubarb dessert’.  ‘Yay, Mom, but what KIND of rhubarb dessert?’.  I finally fell on my linguistic sword and blurted out ‘it’s a Rhubarb Grunt!’  They again looked at me like I’m gone mad and simply said ‘just call it something else if you don’t like that word’ (clearly they did not share the same distaste as me).

I went on to explain I COULDN’T call it something else.  A grunt, like a Slump, Pandowdy, Brown Betty. Buckle, Crisp or a Cobbler was a classic Americana dessert.  Changing its name would be like deciding to start calling George Washington ‘Bob’ or something.  And regardless of the name, I love these desserts.  They have history and roots.  They are rustic, and flavorful, simple and relaxed.  They are not one of those prissy desserts where you wait by the oven door HOPING they work.  Or those that make you feel Martha Stewart, regardless of where she might be in the world, knows what yours looks like and she’s disappointed in you.  These Americana desserts are perfect partners with seasonal fruits, generally have 10 or fewer ingredients and all ingredients you have in your pantry (perhaps less the particular featured fruit).

Sort of a charming thing about grunts and slumps, if something called that can be charming, is the names are about their appearance or sounds they make when cooking.  I did not stand by the oven door to verify mine made such sounds but generally since the fruit is on the bottom mixed with sugar and butter, it bubbles up like a little mud pot to let the cooking steam out of the cakey layer on top.  Knowing that makes me a bit more comfortable calling it by name.

Grunts and slumps are similar and I’ve read they are merely distinguished by the geography from where they come.  Grunts and slumps are generally cooked on the stove top; however, this recipe goes in the oven.  It takes about 10 minutes to prepare, depending on how quickly you slice rhubarb (might be more like 5 minutes).  It emerges with a golden cakey top and perfectly cooked rhubarb underneath; not overly sweet or mushy.  It really is perfection.

For those who have not really cooked with rhubarb, thought it only can be combined with strawberries or think it will be too tart, fear not.  Rhubarb does have a unique tang like no other fruit or vegetable but that is tamed in this recipe.  It showcases beautifully all on its own; it does not need berries; it shines in this recipe.

For me finding new season produce waiting in the store is like running into a long lost friend.  I’m always delighted at my first finding.  With rhubarb showing up I couldn’t wait to snatch some up before it oh-so-quickly disappears.  This Rhubarb Grunt is a wonderful, easy way to celebrate its spring arrival!

Rhubarb Grunt: A Classic Americana Dessert

Prep Time: 10 minutes

Cook Time: 40 minutes

Total Time: 50 minutes

Yield: Serves 6


  • 1 pound Rhubarb, trimmed and cut into ½ inch slices
  • ¾ cups plus ¼ cup Granulated Sugar
  • 4-ounces Unsalted Butter, sliced into tablespoons and then cut into fourths
  • 1 cup Baking Mix (I used King Arthur’s Gluten-Free Baking Mix)
  • ½ teaspoon Kosher Salt
  • 1 cup Heavy Whipping Cream


  1. Preheat the oven to 350 degrees.
  2. Butter an 8 by 12-inch baking dish. Line the bottom evenly with the rhubarb slices.
  3. Sprinkle the rhubarb evenly with 1 cup of the sugar. Evenly distribute the butter on top of the sugar.
  4. In a medium mixing bowl, combine the baking mix, ¼ cup sugar, and salt. Whisk to blend completely.
  5. Add the cream to the mixing bowl and stir to combine (the mixture will be sticky). Spoon the mixture on top of the sugar and butter in the baking dish. Tip: spraying a silicon spatula with non-stick cooking spray before spooning and spreading the flour mixture helps with the sticking.
  6. Cook until the topping turns golden and the fruit is soft and seeping through the top (approximately 40 minutes). Scoop onto plates to serve; a scoop of ice cream or whipped cream may be added if desired.

    That sure looks delicious! Although I can’t quite eat it fresh rhubarb out of the garden like my Dad does I love rhubarb desserts.

    This is fascinating because we can’t grow Rhubarb here (phoenix) but I wonder if we can grow grunts. I love Rhubarb but I understand why you picked the title of the recipe to still have the word Rhubarb in it, it’s fine if it’s similar I think! 🙂 Rhubarb inspired 🙂

    I’m always looking for another rhubarb dessert. The rabbits devoured my patch several years ago, so now I just watch for it to go on sale. Then I cut it up and freeze it till I find a recipe I like. No way I’m going to call it by its real name. I’ll just say rhubarb and the family will either try it or leave it. I think this one will have a lot of takers.

    I’ve never tried Rhubarb before. But, my mom loved it when i was growing up and always used to have it around when it came in season! This looks delicious, would love to try it!

    I have never had rhubarb before. I see it in the store all the time, but whiz by because I didn’t have any recipes in my box that call for it. Now, I do. I can’t wait to try this. It sure looks scrumptious!

      I was the same way Theresa. It’s particularly intuitive in terms of what to do with it and its natural flavor gives absolutely no clue (it’s very tart and bitter). This is a perfect starter recipe and will make you want to cook with it more I’m sure.
