Ingredients for Biscoff Apple Crumble
Here’s what you’ll need to make this crave-worthy crumble:
For the filling:
- 6 cups peeled and chopped apples (Granny Smith and Honeycrisp mix is great)
- 2 Tbsp granulated sugar
- 1 Tbsp brown sugar
- 1 ½ tsp cinnamon
- ½ tsp nutmeg
- 2 tsp cornstarch
- 1 tsp vanilla extract
- 3-4 Tbsp Biscoff spread (adjust amount to your tastes)
For the crumble topping:
- 1 cup old-fashioned oats
- ¾ cup all-purpose flour
- ½ cup brown sugar

How to Make Biscoff Apple Crumble
This is one of those apple desserts that looks and tastes impressive but is surprisingly simple to make. Here’s how to pull it all together:
1. Preheat the oven to 350°F (175°C) and lightly grease an 8×8-inch or 9-inch round baking dish.
2. Make the filling: In a large bowl, toss the apples with sugars, cinnamon, nutmeg, cornstarch, and vanilla until evenly coated. Heat the Biscoff for 5-10 seconds in the microwave to make it easier to stir. Gently mix in a few tablespoons of Biscoff spread for extra gooey flavor.
3. Pour the apple mixture into the prepared baking dish and spread evenly.
4. Make the topping: In another bowl, combine oats, flour, brown sugar, Biscoff cookies, cinnamon, and salt. Then, stir in the melted butter until a clumpy crumble forms.
5. Sprinkle the crumble evenly over the apples, pressing some bits together to make larger clusters.
6. Bake for 35–40 minutes, or until the topping is golden and the apples are bubbling.
7. Cool slightly before serving and adding drizzle
8. Drizzle on melted cookie butter: Heat a few tablespoons of Biscoff cookie butter in the microwave for 5-10 seconds with a bit of oil (I don’t actually measure it, but I would say maybe a 1/2 teaspoon) to make the texture thinner. Quickly mix in the oil with the warmed Biscoff to create a drizzle. Drizzle your Biscoff over the top of your apple crumble.
9. Enjoy warm with vanilla ice cream, whipped cream, or even more cookie butter drizzled on top.
Pro Tips for the Best Apple Crumble
- Use a mix of apples: Combining sweet apples like Honeycrisp with tart ones like Granny Smith gives the filling a great balance of flavors.
- Don’t skip the oats: They add texture and help the crumble topping hold up better against the juicy apples.
- Add extra Biscoff flavor: If you really want to lean into the cookie butter vibes, you can add a bit more to the filling and/or drizzle more Biscoff on top of your baked apple crumble. You won’t be disappointed if you do!
- Double it for a crowd: This recipe can easily be doubled and baked in a 9×13 dish for holiday dinners, potlucks, or big family gatherings.
FAQs
Can I make this ahead of time?
Yes! You can assemble the crumble up to 24 hours in advance and store it in the fridge, unbaked. When you’re ready to serve, just pop it in the oven and bake as directed. You may need to add 5–10 minutes to the bake time if it’s cold from the fridge.
How should I store leftovers?
Leftover Biscoff apple crumble can be stored in the refrigerator for up to 4 days. Reheat in the oven or microwave until warm. It’s delicious straight from the fridge too (don’t ask me how I know…).
Can I freeze this?
Absolutely. You can freeze the unbaked crumble tightly wrapped for up to 3 months. When ready to bake, let it thaw in the fridge overnight, then bake as usual.
Is there a gluten-free version?
It would be a little difficult to make this recipe gluten-free simply because of the Biscoff cookies and cookie butter. Biscoff, or Speculoos cookies, are not gluten free and make up a major part of the flavor of this recipe. However, if you want just a plain apple crumble, you can definitely leave off the Biscoff cookies and Biscoff cookie butter spread, and then sub the flour for a gluten-free flour (make sure your oats are gluten free, too, just in case).
If you’re on the hunt for easy fall desserts that bring comfort and flavor in every bite, this Biscoff Apple Crumble is a must-try. It takes the classic charm of apple desserts and adds a modern, spiced twist with everyone’s favorite cookie butter. Whether you’re baking for friends, prepping for a holiday gathering, or just satisfying your own fall cravings, this crumble is one of those cozy desserts you’ll want to make again and again.
And hey—if you happen to have leftovers for breakfast the next day, this goes great with a warm cup of coffee!
