Easy Rhubarb Crumble Slice Ingredients

For the Pastry Base
Sweet Short Crust Pastry – This forms the sturdy base; you can make it from scratch or choose store-bought for convenience.

For the Filling
Fresh Rhubarb – The star of the show! Adds a tangy flavor that pairs perfectly with sweet notes; you can swap it for apples if you prefer a change.
Red Fruit Jam – Helps soften the rhubarb and adds sweetness; any fruit jam works great, but strawberry or raspberry can elevate the taste.

Plain Flour – Essential for creating the crumble texture; gluten-free flour can be used if needed.
Butter – Provides richness and binds the crumble; opt for plant-based butter for a dairy-free version.
Porridge Oats – Adds a delightful chewiness to the topping; swap them with granola for an extra crunch.
Demerara Sugar – Sweetens while adding a slight crunch; brown sugar or coconut sugar are great substitutes.
Flaked Almonds – Enhance the topping with a nutty flavor and crunch; feel free to use chopped walnuts or pecans as an alternative.

For the Finish
Icing Sugar – A pretty dusting to finish off the slice; this can be optional if you prefer a more rustic look.

Step‑by‑Step Instructions for Easy Rhubarb Crumble Slice

Step 1: Preheat and Prepare
Begin by preheating your oven to 180°C (Gas Mark 4). While it heats, grease and line a 10×10 or 8×10 inch tin with greaseproof paper, ensuring it’s snug and well-covered. This will prevent your Easy Rhubarb Crumble Slice from sticking and help you lift it out later with ease.

Step 2: Cook the Rhubarb
Next, chop the fresh rhubarb into 3cm pieces and place them in a saucepan with the red fruit jam. Cover the pan and cook over low heat for 8-10 minutes until the rhubarb is softened and syrupy. Once cooked, remove from heat and allow the mixture to cool slightly before using it in your slice.

Step 3: Prepare the Pastry
If using homemade sweet short crust pastry, roll it out to a thin layer on a floured surface. Alternatively, roll out your pre-made pastry directly to fit the prepared tin. Aim for a thin layer to prevent a soggy bottom, and then gently press it into the tin to create a solid base for the Easy Rhubarb Crumble Slice.

Step 4: Make the Crumble Topping
In a mixing bowl, combine plain flour and butter, using your fingers to rub them together until the mixture resembles coarse breadcrumbs. Stir in the demerara sugar, oats, and flaked almonds until everything is well mixed. This will form the crunchy topping that perfectly contrasts the tangy rhubarb below.

Step 5: Assemble the Slice
Spread the cooled rhubarb and jam mixture evenly over the prepared pastry base, ensuring it’s well-distributed. After that, sprinkle the crumble topping generously over the rhubarb. Make sure it covers the fruit completely for an even bake, adding to the delightful texture of the Easy Rhubarb Crumble Slice.

Step 6: Bake to Perfection
Place the assembled tin in the preheated oven and bake for approximately 40 minutes. Keep an eye on the slice; it’s done when the top is golden brown and crisp. This lovely color not only enhances the aesthetic but also indicates a deliciously baked Easy Rhubarb Crumble Slice is emerging.

Step 7: Cool and Serve
Once baked, carefully remove the slice from the oven and let it cool in the tin for about 10-15 minutes. Then, gently lift it out using the greaseproof paper. This step ensures the slice holds its shape. You can enjoy it warm or chilled, dusted with a little icing sugar for that final touch!

Easy Rhubarb Crumble Slice Recipe FAQs

How do I choose ripe rhubarb?
When selecting fresh rhubarb, look for firm stalks that are vibrant in color—either a deep red or a bright green.

What if my rhubarb is too watery when cooking?
If you notice your rhubarb is releasing a lot of liquid while cooking, try sprinkling a little extra sugar (about 1-2 tablespoons) to help balance the tartness.

Is rhubarb safe for pets?
