vegan peach blackberry crumble on white plate

Vegan Peach Blackberry Crumble (Crisp)

Print Recipe
This simple summer dessert is bursting with fruit flavour and just the right amount of sweetness! The flourless low FODMAP crumble topping gets a boost of omega 3 fatty acids and plant-based protein from hemp hearts and there is plenty of tummy soothing fibre from the fruit and oats. Use any fruit combination you love to take advantage of what's in season.

Servings 6 servings


  • 9 x 9 baking dish


Fruit Mixture

  • 5 cups peaches and blackberries, fresh or slightly thawed I used 4 cups peaches + 1 cup blackberries
  • 2 tablespoons cane sugar
  • 1 tablespoon arrowroot powder
  • 1 tablespoon freshly squeezed lemon juice
  • 1 teaspoon grated ginger
  • ½ teaspoon cinnamon

Low FODMAP Crumble Topping

  • 1 ¼ cup rolled oats gluten free if needed (learn about the benefits of oats!)
  • ½ cup hemp hearts I use Planet Hemp (not celiac friendly) (learn about the benefits of hemp hearts!)
  • ¼ cup chopped pecans or pecan pieces
  • ¼ cup extra virgin olive oil or avocado oil or melted coconut oil
  • ¼ cup pure maple syrup
  • ½ teaspoon pure vanilla extract
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon salt


  • Preheat oven to 350° Fahrenheit (175°C) and lightly grease a 9x9 baking dish with oil
  • In a medium bowl, mix the fruit with sugar, arrowroot, lemon juice, ginger and cinnamon and pour into baking dish.
  • Wipe out the bowl and then use it to mix the oats, hemp hearts, pecans, olive oil, maple syrup, vanilla, cinnamon and salt.
  • Spread the crumble topping evenly over the fruit and then place the baking dish in the oven. Bake for 40-45 minutes or until crumble topping looks golden brown and fruit mixture is bubbly.
  • Let cool for at least 10 minutes and then serve warm or at room temperature. Will keep on the counter, loosely covered for two days or in the fridge for 3-4 days.


If wanting to make a low FODMAP dessert, keep to the serving size, and substitute a mixture of rhubarb and strawberries. You may wish to 1-2 tbsp of extra sugar to the fruit as rhubarb is a bit tart.
The sweetness of the crumble will depend on the sweetness of the fruit you are using. Taste your fruit; if it's super sweet, you might not even want any added sugar on it! If it's not ripe…or you just like your desserts sweeter, add an extra tablespoon or two of maple syrup to the fruit mixture.
