These porch-swing rhubarb squares are the kind of thing you pull together while the coffee’s brewing and the dew is still on the grass. The recipe comes from the old Amish-style rhubarb crisps that made the rounds at church suppers—simple pantry ingredients, no fuss, just rhubarb, sugar, flour, and butter turning into something sweet, crunchy, and gone before the coffee’s done.
My Grandma June used to set the pan on the porch rail to cool while we swung and talked; by the time the stories wound down, the squares were half gone. This version bakes up in a white dish with a golden, crumbly top and pink, bubbling edges that look just like those old summer mornings.
Serve these rhubarb porch-swing squares warm, scooped or cut into squares right from the baking dish, with hot coffee or tea alongside. A small scoop of vanilla ice cream or a spoonful of lightly sweetened whipped cream is lovely if you want to dress them up a bit, but they’re just as good plain on a chipped plate out on the porch.
They pair nicely with simple breakfast fare—scrambled eggs, bacon, or toast—or as a humble dessert after a meat-and-potatoes supper.
Amish Rhubarb Crisp Squares
Servings: 8-10
Ingredients
4 cups chopped fresh rhubarb (about 1/2-inch pieces, lightly packed)
Directions
Heat your oven to 350°F (175°C). Set a rack in the middle of the oven. Lightly butter or grease a white 8×8-inch or similar-sized ceramic baking dish so the squares release easily after baking.
Rinse the rhubarb and trim off any leaves (they are not edible). Slice the stalks into about 1/2-inch pieces until you have 4 cups. Pat the pieces dry with a clean towel so they don’t water down the filling too much.
In a medium bowl, toss the chopped rhubarb with 3/4 cup of the granulated sugar. Let it sit for about 5 minutes while you prepare the crumb mixture; this helps draw out some juices and softens the tart flavor.
In another bowl, stir together 3/4 cup of the flour, the remaining 1/2 cup sugar, and the salt. Cut the cold butter into small cubes and add it to the bowl.
Using a pastry cutter, two knives, or your fingertips, work the butter into the flour-sugar mixture until it forms coarse, crumbly bits—some sandy, some pea-sized. This will be both your base and your topping, just like Grandma did when she wanted to keep things simple.
Press a little more than half of the crumb mixture firmly and evenly into the bottom of the prepared baking dish to form a thin crust. Use your fingers or the bottom of a measuring cup to press it down so it holds together but doesn’t turn pasty.
Sprinkle the remaining 1/4 cup flour over the sugared rhubarb and toss to coat, then stir in the vanilla and water. The mixture will look a bit syrupy and cloudy—that’s just right and will bubble up around the edges as it bakes.
Spread the rhubarb mixture evenly over the pressed crust, scraping all the sugary juices out of the bowl into the dish so you don’t lose any of that sweet-tart flavor.
Scatter the remaining crumb mixture evenly over the top of the rhubarb, leaving some little clumps and some loose crumbs. This will bake into a golden, crunchy lid with pretty pink juices bubbling around the edges.
Place the baking dish on a baking sheet to catch any drips, then bake at 350°F for 35–45 minutes, or until the top is golden brown and the rhubarb juices are bubbling up around the edges and through a few spots in the topping.
Remove from the oven and set the dish on a heat-safe surface or a speckled counter to cool. Let it cool at least 20–30 minutes so the juices thicken and the squares hold together better when cut.
Serve warm or at room temperature, cut into squares or spooned out in rustic scoops. If you like, add a little ice cream or whipped cream, pour the coffee, and enjoy them on the porch swing before they disappear.
Variations & Tips
If your rhubarb is very tart or you like a sweeter square, increase the sugar in the rhubarb mixture by 1–2 tablespoons. For a more rustic, nutty crunch, you can swap 1/4 cup of the flour in the crumb mixture for rolled oats or finely chopped nuts, though the traditional Amish-style version keeps to simple flour, sugar, and butter.
A pinch of cinnamon or nutmeg stirred into the crumbs will give a cozy, spiced note that works nicely on cool spring mornings. If you only have salted butter, use it and reduce or omit the added salt. Frozen rhubarb can be used in a pinch: thaw it completely, drain off excess liquid, and pat dry before mixing with sugar so the filling doesn’t turn watery.
For food safety, always discard rhubarb leaves, as they are poisonous—use only the stalks. Cool leftovers, cover the dish, and refrigerate within 2 hours of baking; rewarm portions gently in a low oven or microwave until just heated through. These squares are best within a day or two, which is rarely a problem—they’re usually gone before the coffee’s done.
