Still got plums hanging around? Make this healthy plum crisp!

My local farmers market is still overflowing with late-season plums, so I couldn’t resist creating one more crisp recipe before summer slips away *sad face*. If you’re a crisp lover like me, you’ll love my healthy apple crisp, blueberry crisp, or peach crisp, or mixed berry crisp.

So this recipe might be my new favorite way to enjoy plums. We’re talking jammy, juicy plums that turn all pink (keep the skin on!) and syrupy in the oven as they bubble away under a nutty oat topping that bakes up perfectly golden and crisp. Once it comes out of the oven it’s practically begging for a scoop of vanilla ice cream on top.

This easy plum crisp recipe is vegan, gluten free, refined sugar free and ready in 45 minutes! It’s the perfect way to savor the end of summer, or welcome fall.

Ingredients You’ll Need

Here’s what you’ll need to make the best plum crisp! Scroll down to the recipe card to get the full recipe with measurements.

  • Plums: Use fresh, ripe plums for the best flavor and sweetness.
  • Oats: The base of the crisp topping. Rolled or quick oats work here—be sure to use certified gluten-free oats for gluten allergies.
  • Almond Flour: Adds a moist and tender texture to the crisp topping.
  • Sliced Almonds: Feel free to swap for another nut based on what you have—pecans, walnuts, or cashews all work!
  • Maple Syrup: The plums get tossed with a little maple syrup to make them all jammy and juicy. It’s also used in the crisp topping for natural sweetness.
  • Vegan Butter: Adds a golden finish to the crisp topping. You can sub for melted coconut oil.
  • Vanilla Extract: A must.
  • Spices: Cinnamon, ground ginger, and salt add warmth and tie all the flavors together.

Optional: If your plums are extra juicy, toss with 1-2 tablespoons of cornstarch to thicken the filling. I like a juicy filling, so I leave this out.

How to Make Healthy Plum Crisp

This easy plum crisp comes together in just a few simple steps:

  1. Preheat: Preheat the oven to 350°F.
  2. Prep the Filling: Slice the plums (leave the skin on) and add them to a 9-inch pie dish (or similar sized baking dish). Toss with maple syrup, cinnamon, and cornstarch (if using).
  3. Make the Crisp Topping: In a mixing bowl, combine the oats, almond flour, sliced almonds, maple syrup, melted vegan butter, vanilla extract, cinnamon, ground ginger, and a pinch of salt. Stir until crumbly and well combined, then sprinkle the crisp topping evenly over the plum filling.
  4. Bake: Bake for 30 minutes, or until the plum filling is bubbly and the topping is golden brown. If the topping starts to brown too quickly, just cover it with foil and keep baking until the plums are tender.
  5. Serve and Enjoy! Let it cool slightly, then scoop into ramekins and serve warm topped with vegan vanilla ice cream. Enjoy!

Megan’s Tips

  • Use ripe, juicy plums: Fresh, in-season plums make all the difference!
  • Even slices = even bake: Try to slice your plums about the same thickness to get an even bake.
  • Nutrient boost: Add 1–2 tablespoons of chia seeds, hemp seeds, or ground flaxseed to the crisp topping for a little extra fiber and healthy fats.
  • Bake until bubbly: The filling should be juicy and bubbling around the edges—that’s how you know it’s ready. If the topping starts to brown too quickly, just cover it with foil and keep baking until the plums are tender.

Serving Plum Crisp

My favorite way to enjoy this plum crisp? Fresh from the oven (still warm) with a big scoop of vegan vanilla ice cream on top. You know when the ice cream starts to melt into the crisp? That’s the perfect bite!

Other serving ideas:

  • Top with coconut whipped cream or vegan ice cream
  • Serve with vegan yogurt for a cozy fall breakfast
  • Add a drizzle of maple syrup or almond butter on top for a little extra indulgence

Storing + Reheating

Store any leftovers covered in the fridge for 3-4 days. Reheat in the oven at 325ºF until warm and crisp (about 10-12 minutes), or microwave if you’re short on time.

This plum crisp feels like that cozy sweet spot between summer and fall. I hope it brings a little seasonal joy to your kitchen, just like it does to mine!
