Ingredients

2 pounds plums, pitted and sliced

⅓ cup honey or maple syrup

3 tablespoons arrowroot starch or cornstarch

½ teaspoon ground cinnamon

1 cup old-fashioned oats (certified gluten free if needed)

½ cup packed almond flour

⅓ cup chopped pistachios, almonds, or walnuts

⅓ cup lightly packed coconut sugar or brown sugar

1 teaspoon ground ginger

¼ teaspoon fine salt

4 tablespoons butter, melted

3 tablespoons plain yogurt (regular or Greek)

Vanilla ice cream, whipped cream, or yogurt for serving

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9-inch baking dish with butter or nonstick spray.
  2. In a large bowl, combine sliced plums, honey or maple syrup, arrowroot starch, and cinnamon. Toss gently and transfer to the prepared baking dish.
  3. In a medium bowl, mix oats, almond flour, chopped nuts, coconut sugar, ginger, and salt. Stir in melted butter and yogurt until slightly crumbly.
  4. Spread the topping evenly over the plum filling.
  5. Bake 35–40 minutes until the topping is golden brown and filling is bubbling. Let cool slightly before serving.
  6. Serve warm with vanilla ice cream, whipped cream, or yogurt.

Notes

Swap plums for peaches, nectarines, or cherries.

Use a mix of your favorite nuts for the topping.

Add a pinch of cardamom or nutmeg to the topping for extra warmth.

Make it vegan by replacing butter with coconut oil and yogurt with plant-based alternatives.

Stir in a teaspoon of vanilla extract to the plum filling for added depth.

Toast nuts and oats lightly before mixing for extra crunch.

Store leftovers in the fridge up to 3 days and reheat in the oven.
