Prep and fill
- Preheat the oven to 375F and grease a 9x13 baking dish. Set the dish on a sturdy baking surface so it’s ready to fill.
- Toss the apple slices with granulated sugar, cinnamon, nutmeg, cornstarch, lemon juice, and Biscoff cookie butter until evenly coated. Spread the mixture in the greased dish in an even layer.
Make the Biscoff crumble topping
- Combine the crushed Biscoff cookies, all-purpose flour, rolled oats, brown sugar, and cinnamon in a mixing bowl. Rub/cut in the cold unsalted butter until the mixture forms clumpy crumbs.
- Drizzle the melted Biscoff spread over the crumb mixture and toss briefly. Stop once the crumbs look lightly coated rather than glossy.
- Scatter the crumble evenly over the apples, covering as much surface as possible. Press very lightly so the topping adheres.
Bake and serve
- Bake at 375F for 35-40 minutes, until the topping is golden and the apples are bubbling. If the top darkens too fast, loosely tent with foil after 25 minutes.
- Let the crumble stand briefly, then serve warm with vanilla ice cream. Spoon so you get crisp topping with hot, spiced apples.
Notes
For the best clumpy crumble, keep the butter cold and stop mixing as soon as you see pea-size clusters. Store leftovers covered in the refrigerator up to 3 days; reheat individual portions in the microwave until hot. Freezing is not recommended because the crumb can soften after thawing. If you want a lighter option, use unsweetened vegan butter sticks and dairy-free vanilla ice cream.
