✔️ Why you'll love this recipe!
- These apple crumble bars are fuss-free and easy treat to whip up.
- Giving the traditional apple crumble a Biscoff twist not only adds a burst of flavour but also brings a modern, trendy spin to a beloved classic.

🛒 Ingredient notes
For the oat crumble:
Oats - use porridge oats or rolled oats (jumbo oats or quick cook aren't suitable for this recipe).
Flour - plain white flour or use wholemeal plain flour for a healthier twist.
Butter - a block (250g) of unsalted butter. The butter must be chilled and cubed.
Sugar - light brown sugar or light muscovado sugar gives the best caramel flavour.
Cinnamon - ground cinnamon, or use mixed spice.
Nuts - chopped nuts add texture and crunch to the apple bars. I like to use walnuts, but pecans would also work well.
For the apple layer:
Apples - I like the tartness of Bramley apples, but if you prefer something sweeter use Granny Smith, Pink Lady or Gala apples.
Lemon Juice - a squeeze of lemon juice helps to prevent the apples from turning brown when sliced, and also elevates the flavour of the finished recipe.
Biscoff Spread - smooth Biscoff spread sweetens the tart cooking apples and provides a gooey sticky layer to the bars.
🔪 How to make Biscoff apple crumble bars
The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post
One: Preheat the oven to 190 °C (170 °C fan/ 375 °F/ Gas 5) and line a 20cm (8") square baking tin with baking paper.
Two: Place the oats and flour into a large mixing bowl and rub in the cold cubed butter with your fingertips until crumbs form.
Three: Stir in the light brown sugar, cinnamon, and chopped walnuts.
Four: Press two-thirds of the crumble mixture into the prepared tin and pack down tightly with the back of a metal spoon. Set aside while you prepare the apples.
Five: Peel, core and slice the apples and lay them over the top of the crumble base layer. Squeeze over the lemon juice.
Six: Warm the Biscoff spread in the microwave for 20 seconds, and then use a spoon to drizzle it over the apples.
Seven: Top with the remainder of the crumble mix and lightly press down with your hand. Bake in the oven for 35 minutes until golden brown. Allow to cool completely before cutting into bars.
Top Tips
- Use chilled butter in the crumble to achieve a crumbly crisp topping, enhancing the bar's overall texture.
- Use smooth Biscoff spread and soften it in the microwave to make it easier to drizzle over the apples.
- Allow the bars to cool completely before slicing to ensure they hold their shape and don't crumble.
