Warm Plum & Fig Crisp with Walnut-Oat Crumble

A small-batch September fruit crisp made with plums, fresh figs, walnuts, oats, and cinnamon, with very little added sweetener.

This is the kind of dessert I like in September.

It is warm, but not heavy. The fruit still does most of the work. And because ripe plums and figs are naturally sweet, the recipe does not need much added sugar.

It also works beautifully in a toaster oven.

Warm Plum & Fig Crisp

Serves 4

Fruit layer

  • 4 ripe plums, pitted and sliced
  • 5 fresh figs, stems removed and quartered
  • 1 tablespoon maple syrup or honey, optional
  • 1 tablespoon cornstarch or arrowroot
  • 1/2 teaspoon cinnamon
  • 1/4 teaspoon ground ginger
  • Pinch of sea salt

Walnut-oat crumble

  • 1/2 cup rolled oats
  • 1/3 cup chopped walnuts
  • 2 tablespoons whole-wheat flour or oat flour
  • 1 tablespoon butter or coconut oil, softened
  • 1 tablespoon maple syrup
  • 1/2 teaspoon cinnamon
  • Pinch of salt

Directions

  1. Preheat oven or toaster oven to 375°F.
  2. Lightly grease a small baking dish.
  3. Toss plums and figs with maple syrup if using, cornstarch, cinnamon, ginger, and salt.
  4. Spread fruit in the baking dish.
  5. Mix oats, walnuts, flour, butter or coconut oil, maple syrup, cinnamon, and salt until crumbly.
  6. Scatter evenly over the fruit.
  7. Bake 25 to 30 minutes, until fruit is bubbling and topping is lightly browned.
  8. Let rest 10 minutes before serving so the juices thicken slightly.

Healthy benefits

Plums and figs provide fiber, potassium, and a range of plant compounds. Walnuts contribute unsaturated fats, plant protein, magnesium, and alpha-linolenic acid, a plant omega-3 fatty acid.

This is still dessert. The goal is not to turn every dessert into a health food. I simply like recipes where fruit, whole grains, and nuts are doing most of the work.

Serving suggestions

Serve warm with:

  • plain Greek-style yogurt
  • vanilla plant-based yogurt
  • cottage cheese for a higher-protein twist
  • a small scoop of vanilla frozen yogurt

For breakfast, reduce the maple syrup and serve with yogurt.

Storage

Refrigerate leftovers for up to three days.

Reheat in the toaster oven at 325°F until warm. The topping will stay crisper than it does in the microwave.

Swaps

No figs? Use pears.

No walnuts? Use pecans or sunflower seeds.

No plums? Use apples, but add a few extra minutes of baking because apples are firmer.

This is a very simple way to use the last of late-summer fruit while letting fall flavors start to move in.

— 1 tbsp maple syrup or honey (optional)
— 1 tbsp cornstarch or arrowroot
— 1/2 tsp cinnamon
— 1/4 tsp ground ginger
— Pinch of sea salt
Walnut-Oat Crumble

— 1/3 cup chopped walnuts

— 1 tbsp butter or coconut oil, softened
— 1 tbsp maple syrup
— 1/2 tsp cinnamon
— Pinch of salt
Directions
1
Preheat oven or toaster oven to 375°F. Lightly grease a small baking dish.
2
Toss plums and figs with maple syrup if using, cornstarch, cinnamon, ginger, and salt until evenly coated.
3
Spread the fruit evenly in the baking dish.
4
Mix oats, walnuts, flour, butter or coconut oil, maple syrup, cinnamon, and salt together until the mixture is crumbly and holds together when pressed.
5
Scatter the crumble evenly over the fruit.
6
Bake 25 to 30 minutes, until the fruit is bubbling and the topping is lightly browned.
7
Let rest 10 minutes before serving so the juices thicken slightly.
Storage: Refrigerate leftovers for up to three days. Reheat in a toaster oven at 325°F until warm — the topping stays crisper than it does in the microwave. For breakfast, reduce the maple syrup and serve with yogurt.
Healthy Benefits
Plums provide fiber, potassium, and plant compounds that support digestive and heart health.
Figs are a good source of fiber, calcium, and natural sweetness that reduces the need for added sugar.
Walnuts contribute unsaturated fats, plant protein, magnesium, and alpha-linolenic acid, a plant omega-3 fatty acid.
Rolled oats add soluble fiber, including beta-glucan, which supports healthy cholesterol levels.
Cinnamon and ginger add warmth and both have anti-inflammatory properties.
This is still dessert. Fruit, whole grains, and nuts are doing most of the work here — and that is enough.
