Ingredients for the Perfect Buttery Shortcrust Rhubarb Slices
Okay, let’s talk supplies! Getting the right ingredients is critical, especially when we are aiming for that melt-in-your-mouth shortcrust. I always buy local rhubarb when I can—the brighter the pink stalks, the better they taste, in my opinion! Remember, the butter for the pastry has to be ice cold; that’s non-negotiable if you want flaky coverage. This recipe works beautifully, just like my recipe for apple pie bars, because we prioritize good, cold fat.
For the Shortcrust Pastry
- 225g unsalted butter, cold and cubed
- 300g all-purpose flour
- 50g granulated sugar (for the crust)
- 1 large egg yolk
- 3-4 tablespoons ice water
For the Sweet and Tart Rhubarb Filling
This filling relies on the cornstarch to soak up all those lovely juices the rhubarb releases. Don’t skip it, or you’ll end up with a soupy mess instead of perfect rhubarb lattice slices recipe squares!
- 600g fresh rhubarb, chopped into 1-inch pieces
- 150g granulated sugar (for the filling)
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
How to Prepare the Lattice Rhubarb Snitter (Rhubarb Slices)
Alright, this is where the magic happens! We need to treat our dough kindly—gentle handling stops gluten development, which is the enemy of a flaky crust. Don’t worry if you haven’t done a lattice before; I’ll walk you through every step of this traditional rhubarb snitter tutorial.
Making the Buttery Shortcrust Dough
First things first: get those cold butter cubes mixed with the flour and 50g of sugar. Use your fingertips—or a pastry blender if you like—until it looks like coarse, pebbly sand. If you see pea-sized chunks remaining, that’s perfect! Now, drizzle in that icy water and yolk. Mix it just until it clumps without looking dusty or dry. Stop right there! Overmixing is the quickest way to tough pastry. Divide that dough, press it into two disks, wrap them up, and let them chill out in the fridge for at least 30 minutes. They need that time to relax before rolling.
Assembling the Lattice Rhubarb Snitter
While that dough chills, mix up your filling—rhubarb, sugar, cornstarch, vanilla. That cornstarch really locks down the juice so you don’t get a liquid bottom layer. Prep your 9×9 pan. Then, roll out one disk and press it into the bottom for the base. Pour that juicy rhubarb in evenly. Now for the fun part! Roll out the second disk and use a sharp knife or pizza cutter to slice even 3/4-inch strips. Lay those strips across the filling, alternating directions (over-under-over) to build your lattice. Just like I learned when I tried my first lattice pie crust, make sure you crimp those edges together with the bottom crust gently to seal everything tight.
Baking and Cooling the Lattice Top Rhubarb Pie
We need heat! Preheat to a strong 200°C (400°F). Pop the snitter in for 15 minutes. That initial blast helps set the crust before the fruit gets too hot. Then, drop the temperature down to 180°C (350°F) and bake for another 30 to 40 minutes until the topping is beautifully golden brown, and you see the filling bubbling happily underneath. This part is crucial: You HAVE to let these cool down completely—and I mean completely—in the pan before slicing. If you cut them warm, that runny filling will just ooze out, and you’ll lose the beautiful structure of your Lattice Rhubarb Snitter (Rhubarb Slices).
Tips for the Perfect Lattice Crust for Fruit Slices
Lattice work can feel intimidating, but honestly, it’s just weaving; you’ve got this! My biggest secret for getting those strips to lay perfectly flat in your homemade rhubarb baked squares—without stretching and tearing—is to chill them after you cut them. Once you cut the strips from the second dough disk, lay them out on a baking sheet and pop them back in the fridge for about 10 minutes. This firms them up just enough so they don’t sag when you place them over that juicy rhubarb filling.
Also, texture is everything! Remember that note about the egg wash? Before you pop it in the oven, brush the finished lattice lightly with one beaten egg. It makes the crust incredibly shiny and gives it a rich, professional golden color. If you want to go the extra mile, a light sprinkle of coarse sugar on top before baking adds a lovely little crunch.

Ingredient Notes and Substitutions for Your Lattice Rhubarb Snitter
I know you might be looking at that sugar amount and thinking I’ve gone a bit wild, but trust me, rhubarb needs that sweetness to balance its natural tartness! If you taste your raw rhubarb and it seems exceptionally sour—maybe it’s early spring stuff—you can certainly bump that filling sugar up by about 25g. It won’t hurt a thing!
What if you can’t get fresh rhubarb? That’s okay! You can use frozen rhubarb for these rhubarb lattice slices recipe squares, but you absolutely must thaw it first and drain off almost all the liquid before mixing it with the dry ingredients. Since frozen rhubarb releases more moisture, I usually add an extra teaspoon of cornstarch just to make sure we don’t get that soggy bottom we talked about earlier.

Serving Suggestions for Classic Rhubarb Baked Dessert
You simply cannot eat this masterpiece straight from the cooling rack—well, you *can*, but you absolutely shouldn’t! The best way to enjoy these slices is when they are lukewarm or room temperature. The classic choice is always rich vanilla ice cream melting into that tart filling, or maybe a generous dollop of fresh, lightly sweetened whipped cream.
If you’re enjoying this **classic rhubarb baked dessert** after dinner, skipping the cream and serving it with a very strong, hot black tea is wonderful. The dark brew cuts right through the buttery pastry perfectly. You might love these warm apple slices too, baked apples with cinnamon walnuts, served the same way!
Storage and Make Ahead Rhubarb Slices Baking Recipe
Since making a beautiful lattice takes a little effort, you’ll be happy to know these **Lattice Rhubarb Snitter (Rhubarb Slices)** travel so well and keep beautifully!
Once completely cooled, you can store them airtight at room temperature for about two days, although they are best on day one. If you need them to last longer, pop them into an airtight container in the fridge for up to five days. If they look a little dull when you pull them out of the cold, just warm them up for 15 seconds in the microwave—it brings the butter back to life! For planning ahead, here’s a hint: make both pastry disks a day early, keep them wrapped tightly in the fridge, and you can move straight into assembly the next day. That cuts down significantly on your active baking time!

Frequently Asked Questions About Lattice Rhubarb Snitter
I totally get it; when you put this much elbow grease into a buttery shortcrust rhubarb slices project, you want it to turn out perfectly! Here are the things people ask me most often after they look over this classic rhubarb baked dessert recipe.
Can I use frozen rhubarb instead of fresh for these rhubarb lattice slices recipe?
You absolutely can! We all have to rely on frozen when the season dips. The key is thawing it completely and draining off as much liquid as you possibly can—I mean really blot it dry. Because frozen rhubarb softens more, I usually add an extra teaspoon of cornstarch just to make sure the filling sets up nicely and you don’t end up with a soupy bottom layer.
What is the secret to a perfect lattice top rhubarb pie?
It all comes down to temperature! The secret to a lovely, crisp lattice is making sure your dough strips are properly chilled before you start weaving them over the fruit. If the dough is too warm, it stretches, pulls, and buckles in the oven. Keep the dough cold, don’t force the strips—just weave gently—and you’ll get that beautiful, tight pattern that defines the Lattice Rhubarb Snitter (Rhubarb Slices).
Why did my buttery shortcrust rhubarb slices turn out soggy on the bottom?
Ugh, the dreaded soggy bottom! It’s heartbreaking after all that work. With this particular recipe—using the high initial oven heat—it’s usually because the filling wasn’t thick enough, or maybe you didn’t bake it quite long enough for the juices to set. Make sure you use the full amount of cornstarch. Also, never pour fruit filling onto a fully unbaked bottom crust if the fruit is very watery; sometimes, I “blind bake” the base for 10 minutes before adding the filling if I’m worried!

You should always see these values as a general guideline, though, as your specific rhubarb size or brand of butter can slightly change the final count.
It’s important to remember that we are using good, wholesome ingredients here. Baking with care means using real butter, which contributes to the fat content, but it’s what gives these rhubarb lattice squares that phenomenal flaky texture we worked so hard for!
