Ingredients You’ll Need

This Sourdough Strawberry Shortcake Crumble Slice is made with humble, inexpensive ingredients. You probably have all of them in your pantry already! This recipe contains no eggs, baking powder, or baking soda.
Sourdough Shortbread Base + Crumble Topping
A sweet, buttery shortbread base that’s lightly crisp yet chewy — the perfect shortcake-style layer. You’ll crumble up half of this to make the streusel-style topping.
- Butter – Cubed and softened for easy creaming.
- Sugar – I use a mix of golden raw sugar and white caster sugar for subtle caramel flavor and a golden hue. For a crisper base, use 100% white sugar.
- Salt – Enhances the sweetness and prevents blandness.
- Sourdough Discard – Adds subtle tang and helps bind the dough. You can let it ferment in the fridge for up to 24 hours for a deeper flavor.
- Flour – All-purpose flour works best, though bread flour also produces great results.
Strawberry Conserve Filling
This layer gives all the flavor of a classic strawberry shortcake — juicy, sweet, and slightly tart. Or, to make it sugar free, you could use this sugar free strawberry jam instead.
- Strawberries – 2 cups sliced. Use fresh strawberries for the best flavor and texture (frozen ones add too much moisture).
- Sugar – Adds sweetness and helps set the filling.
- Lemon juice – balances the sweetness and adds vibrancy to this layer.
Equipment You’ll Need
- 1 large mixing bowls – For the base and crumble mixture.
- 1 medium sized pot – for the strawberry filling.
- Wooden spoon – For creaming and mixing.
- Baking paper – Essential to prevent sticking; let it hang over the sides for easy lifting.
- Flan or baking dish – A 27 cm flan dish or 17×27 cm baking dish works perfectly.
- Oven – This slice bakes twice: once for the base and once after assembling the layers.

Serving Suggestions
These Sourdough Strawberry Shortcake Crumble Bars are divine on their own, but even better served warm with:
- Custard
- Vanilla ice cream
- Whipped cream
- Or a dollop of Greek yoghurt for a lighter option

Variations and Tips

- Sugar choice matters: Raw sugar gives a caramel note and softer texture; white sugar yields a crisper bite. I think the crispier bit goes better with the jammy filling, but caramel notes are also nice!
- Make ahead: Prepare the base and crumble the day before and refrigerate for easier assembly and mild fermentation benefits.
- Add oats to the remainder of the short crust before crumbling over the top, for added texture.
- Fruit swaps: Use any fresh berry or jam if strawberries are out of season — think raspberry, apricot, or plum. Or, use this sugar-free strawberry jam for a healthy swap.
- Serving trick: Cut into wedges for a pie-like dessert presentation.
