🕰️ A Brief History of Rhubarb in Baking
Rhubarb originated in China over 2,000 years ago, initially prized for medicinal purposes. It wasn’t until the 18th century, when sugar became more widely available in Europe, that rhubarb found its way into sweet dishes. The British popularized rhubarb pies and crumbles, and early American settlers brought it across the Atlantic.
In baking, rhubarb became a quintessential spring ingredient, used in everything from pies to crisps to jams. These Rhubarb Crumb Bars are a modern twist on those beloved traditions — portable, pretty, and absolutely satisfying.
🍓 Ingredients
For the Crust & Crumb Topping (dual-purpose):
- 1 ½ cups all-purpose flour
- 1 ½ cups old-fashioned rolled oats
- 1 cup packed light brown sugar
- ¾ cup unsalted butter, melted
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 teaspoon vanilla extract (optional but recommended)
For the Rhubarb Filling:
- 3 cups rhubarb, diced into ½-inch pieces (fresh or frozen, thawed and drained)
- ¾ cup granulated sugar
- 1 tablespoon cornstarch
- 1 tablespoon lemon juice (brightens the tartness)
- Zest of 1 lemon
- 1 teaspoon vanilla extract
🥣 Method
1. Preheat & Prepare
- Preheat your oven to 350°F (175°C).
- Line a 9×13-inch baking dish with parchment paper or lightly grease it. This makes removal easier and ensures even baking.
2. Make the Crust & Topping
- In a large bowl, combine flour, oats, brown sugar, baking soda, and salt.
- Stir in the melted butter and vanilla extract until the mixture becomes crumbly but cohesive.
- Press two-thirds of this mixture firmly into the bottom of your prepared pan. Reserve the remaining one-third for the topping.
3. Prepare the Rhubarb Filling
- In another bowl, mix rhubarb, granulated sugar, cornstarch, lemon juice, lemon zest, and vanilla extract until the fruit is well coated and the sugar begins to dissolve.
- Spread the rhubarb mixture evenly over the crust.
4. Add the Crumb Topping
- Sprinkle the remaining oat mixture generously over the rhubarb layer. Leave some clumps for a more rustic texture — these will turn golden and crisp during baking.
5. Bake
- Bake for 40–45 minutes, or until the top is golden and the filling is bubbly around the edges.
- Let cool completely in the pan. For cleaner slices, chill in the fridge for an hour before cutting.
💕 Serving & Sharing With Lovers
These bars aren’t just for yourself. Cut them into squares, wrap them in parchment, and tuck them into a picnic basket with fresh strawberries, a chilled bottle of rosé, and your favorite blanket. These crumb bars are memory-makers — passed between fingers sticky with fruit, enjoyed under open skies or soft candlelight.
Sharing food is one of the oldest love languages — and these rhubarb crumb bars, blushing and beautiful, are a perfect expression of affection.
🔍 Tips & Variations
- Add strawberries to the rhubarb for a more traditional flavor blend (use 2 cups rhubarb + 1 cup chopped strawberries).
- Use almond extract in the topping for a nutty twist.
- Top with whipped cream or a scoop of vanilla bean ice cream if serving warm.
- Make it gluten-free: Substitute the flour with a gluten-free all-purpose blend and ensure oats are certified gluten-free.
