The Complete Guide to Sugar Alternatives: Everything You Need to Know →Classic Apple Crumble with Jaca
Golden, cinnamon-spiced apples baked under a crunchy, buttery oat crumble topping — all sweetened with Jaca (allulose) instead of conventional sugar. Easy to make and impossible to resist, especially with a scoop of vanilla ice cream. This is a Jaca-adjusted healthier version of the beloved classic.
Ingredients
- 2 pounds Granny Smith apples, peeled and cut into 1/2-inch cubes (about 6 medium apples)
- 1 tablespoon all-purpose flour (for filling)
- 1 cup Jaca (allulose) for filling (replaces 1/2 cup white sugar at 2x ratio)
- 2 tablespoons lemon juice
- 1/2 teaspoon ground cinnamon (for filling)
- 1 cup rolled oats
- 1 cup all-purpose flour (for topping)
- 2 cups Jaca (allulose) for topping (replaces 1 cup brown sugar at 2x ratio)
- 1/2 teaspoon baking powder
- 1 teaspoon ground cinnamon (for topping)
- 1/2 cup unsalted butter, melted (1 stick / 125g)
- pinch of salt
- vanilla ice cream (for serving)
Sweetener Used
3 cups Jaca (allulose) total Allulose
Replaces: 1/2 cup white sugar + 1 cup brown sugar
Instructions
- 1
Preheat oven to 350°F (180°C).
- 2
Peel the apples and cut them into 1/2-inch cubes. Place in a large bowl.
- 3
Sprinkle the apples with 1 tablespoon flour, 1 cup Jaca (allulose), 2 tablespoons lemon juice, and 1/2 teaspoon cinnamon. Toss to coat evenly, then spread into a 9x13-inch (or 1.5-quart) baking dish.
- 4
In a separate bowl, combine 1 cup rolled oats, 1 cup flour, 2 cups Jaca (allulose), 1/2 teaspoon baking powder, 1 teaspoon cinnamon, and a pinch of salt.
- 5
Pour the melted butter over the dry mixture and stir until clumps form, like wet sand.
- 6
Spread the crumble topping evenly over the apples, crumbling with your fingers to get that classic nubbly texture.
- 7
Bake for 30 to 40 minutes, until the topping is golden brown and the apple filling is bubbling around the edges.
- 8
Remove from oven, cover loosely with foil, and let stand 10 minutes before serving. This lets the apple juices thicken slightly.
- 9
Serve warm with a generous scoop of vanilla ice cream.

This is a Jaca-adjusted healthier version of Classic Apple Crumble — all the warm, cozy flavor without conventional sugar.
Pro Tips
- Granny Smith apples work best because their tartness balances the sweetness. You can use any apple variety you prefer.
- Do not skip the tablespoon of flour in the filling — it thickens the juices into a light, jammy syrup instead of watery liquid.
- The crumble topping should look like chunky wet sand before you spread it. If it is too dry, add another tablespoon of melted butter.
- This recipe also works beautifully with pears or peaches in place of apples.
- Jaca (allulose) caramelizes and browns just like conventional sugar, so your crumble topping will get perfectly golden.
