Ingredients and Preparation
Each layer of these bars brings something essential: the tender crust gives way to lush almond filling, while jewel-toned rhubarb creates a tart, glossy finish. Here’s what you’ll need for a standard 8″x8″ pan batch.
Crust
- 1 cup (125g) all-purpose flour
- 1/4 teaspoon fine sea salt
- 1/4 cup (50g) granulated sugar
- 1/2 cup (115g) unsalted butter, cold preferred
Filling
- 3/4 cup (75g) sliced almonds, ideally toasted and cooled
- 1 tablespoon (10g) all-purpose flour
- A few pinches sea salt
- 6 tablespoons (75g) plus 1 teaspoon (5g) granulated sugar
- 5 tablespoons (70g) unsalted butter, cold is fine
- 1 large egg
- 1/2 teaspoon almond extract (or 2 teaspoons brandy or a different flavoring, optional)
- 1/2 pound rhubarb (about 225g)
To Finish
- Powdered sugar, or
- 1/4 cup jam of your choice (for a glossier look)
Step-by-Step Instructions
1. Lining the Baking Pan
To ensure easy removal and clean edges, use two sheets of parchment paper. Trim each to fit the width of your 8″x8″ square pan. Press one sheet across the bottom and up the sides, then layer the second sheet perpendicular for full coverage.
2. Making the Crust
- Combine the flour, salt, and sugar in a food processor.
- Add butter, cut into chunks, and process until the mixture forms moist clumps. This may take up to a minute—persist beyond the ‘crumbly’ stage until it clumps together.
- Transfer the dough to the prepared pan, pressing it evenly across the bottom and 1/4-inch up the sides.
- Bake for 15 minutes, or until pale golden at the edges. For quicker cooling, place the baked crust in the freezer for 10–15 minutes while preparing the filling.
3. Creating the Almond Filling
- Grind almonds, 6 tablespoons sugar, flour, and salt in the processor until the almonds are powdery-fine.
- Add the butter (in chunks), pulsing until no visible pieces remain.
- Add the egg (and optional flavoring), blending until just combined.
- Spread the almond cream evenly over the (mostly cooled) crust.
4. Arranging the Rhubarb
- Trim and halve the rhubarb stalks lengthwise (like splitting a hamburger bun).
- Slice diagonally into 1.25-inch pieces, keeping tops and bottoms stacked.
- Arrange on top of the almond filling in a chevron or ombré pattern to highlight the color gradient, placing flatter sides down and V-ing pieces together.
- Sprinkle with 1 teaspoon sugar to enhance gloss and tame tartness.
5. Baking and Finishing Touches
- Bake at 350°F for 45–55 minutes, or until the top is golden and a toothpick inserted into the filling comes out clean.
- Allow bars to cool thoroughly in the pan. For jam-glossed bars, gently warm jam and brush on top; for an elegant matte look, dust with powdered sugar right before serving.
- For the cleanest formation, chill the bars before slicing. Use a serrated knife and cut gently for neat edges.
Tips and Troubleshooting
- No food processor? Cream softened butter with sugar, then beat in flour and salt until just combined. Press into the pan, chill 15 minutes, and proceed as normal.
- Slicing rhubarb: Arranging stalks from green to pink creates a gradient effect. Coloring will deepen during baking but some shifting is normal.
- Chilling: For sharp, precise bar cuts (especially for serving), chilling in the fridge or freezer is highly recommended.
- Storage: Bars will keep at room temperature for about a day, but stay fresher and slice more cleanly when kept refrigerated for up to 1 week.
- Doubling the recipe: Use a 9×13-inch pan and double the amounts for larger batches.
Serving Suggestions & Variations
- Picnics and potlucks: Pack in a lidded container with layers of waxed paper—great for outdoor gatherings.
- Flavor swaps: Try chopped strawberries (for a sweeter tone) or apricots if rhubarb isn’t available, but keep slices compact to prevent sogginess.
- Finish with flair: Dust with confectioners’ sugar for a classic look, or brush with apricot or berry jam for shine and a hint of extra flavor.
- Textural twist: Sprinkle a handful of sliced almonds over the fruit just before baking for crunch.
Why Rhubarb and Almond Are a Perfect Match
Rhubarb’s high acidity and inherent tartness perfectly balance the rich, creamy, and gently sweet almond filling. The combination is not only flavorful, but visually pleasing—the gentle contrast of the green-to-pink rhubarb bands over a golden cream base evokes spring’s freshness in every slice.

Frequently Asked Questions (FAQ)
How do I get a chevron or ombré rhubarb pattern?
Slice your rhubarb diagonally and arrange matching top and bottom halves together to form V-shapes. For ombré, group green segments at one side, transitioning to pink at the other.
Can I make these bars ahead of time?
Yes. The bars keep well chilled for up to one week and taste best within the first three days. Consider dusting with confectioners’ sugar or glazing just before serving for the freshest appearance.
What if I don’t have a food processor?
You can use room temperature butter: beat it with sugar, then add flour and salt to make the crust. For the filling, very finely chop the almonds and mix by hand with remaining filling ingredients is perfectly acceptable.
Can I freeze almond rhubarb picnic bars?
Absolutely. Cut bars can be well-wrapped and frozen for up to two months; thaw in the fridge to maintain texture and appearance.
Are substitutions possible?
You may swap in firm, tart fruits (like underripe apricots or thinly sliced green apples) or use gluten-free flour for the crust. Flavorings like citrus zest or vanilla also work well in the filling.
Reader Tips and Community Notes
- If using very tart rhubarb, consider increasing the sugar on top slightly or glazing generously.
- Several bakers enjoy adding a touch of orange or lemon zest to the almond mixture for extra brightness.
- Let bars cool thoroughly for the cleanest slicing—overnight in the fridge makes perfection easy.
