Why You’ll Love This Plum Crisp Recipe

This plum crisp recipe is so easy to make, with only a few ingredients. It is a one-pan dish, where you dump the fruit in, layer it with the topping mixture, and then let the heat do the rest. 

It is a healthy and lightly-spiced recipe, high in fiber and phytonutrients. You can feel good about eating it for breakfast, snack, or dessert! And since this crowd-pleasure comes together fairly quickly, it’s a great option for get togethers like brunch or BBQs.

How to Make Vegan Plum Crisp

Chopped plums fill a white baking dish.
Oat crumble ingredients are mixed in a bowl.

Step 1: First, preheat the oven to 350F. Also, grease the 8×8 dishpan to be used as soon as the fruit and mixture are ready. Then, add the chopped plums to the baking dish and mix in ¼ cup of brown sugar.

Step 2: Next, combine flour, oats, salt, allspice, cinnamon, vanilla, and melted vegan butter in a bowl. Mix them all together until well combined.  

Oat crumble topping covers the plums before baking.

Step 3: Then, scoop the oat mixture on top of the plums and spread evenly. I like to sprinkle a little brown sugar on top to have that caramelized flavor. Lastly, place in the oven for about 40 minutes.

FAQs for Vegan Plum Crisp

Why use plums in a crisp?

Stone fruits, which range from cherries (check out this easy cherry pie) to peaches to plums, are among the sweetest, juiciest, and finest tree-grown fruits. I find plums to be underrated and often used only for jam-making. But, they are inexpensive, nutritious, and bring vibrant taste and color to any dish, including a sweet crisp.

How is a crisp usually served?

Enjoy it “a la mode” by placing a dollop of vegan vanilla ice cream or this (banana ice cream) on top to make it into a summer delectable treat! You can also top it with vegan yogurt (like this yogurt parfait) if you prefer to add a touch of refreshing tanginess. 

A serving of plum crumble is topped with dairy-free ice cream.

Variations and Add-ons

  • Other Fruits: One thing that I like about this recipe is its flexibility. The plums can be substituted with other rustic fruits like blackberries, peaches, apricots, or raspberries.  You can be creative and do a combo too!  It is so versatile that it can adapt to whatever fruits are in season.  
  • Coconut Flour: As an alternative to all-purpose flour, you can use coconut flour. However, the juicier the plums, the more coconut flour you’ll need.
  • Nuts: Add your favorite nuts in there. Almonds, cashews, or pistachios will work. You can even add on this vegan date caramel sauce on top for extra goodness!

Storage Instructions

Crisps and crumbles desserts are best eaten right away. As it cools down, the moisture and liquids from the fruit can cause the dessert to become soggy, especially if left out too long. A great way to preserve its crunch is to allow it to cool to room temperature, wrap it with a paper towel, and then place it in an airtight container. The paper towel absorbs any extra condensation that could otherwise make the crisp soggy.

Fridge: Place it in the refrigerator where it can last up to 3 days.

To reheat, bake the plum crisp at 350 degrees for about 15 minutes. You may also reheat the plum crisp in the microwave for around 40 seconds per each serving.

Plum crumble is served from a baking dish onto a small plate.

    1. Thank you for the feedback, and I’m sorry it didn’t set for you! Plums can vary quite a bit in how much juice they release depending on how ripe they are, and very ripe plums release a lot more. I haven’t tested it, but tossing the plums with 1 to 2 Tablespoons of cornstarch before adding the topping should help thicken the filling. Letting it cool for 20 to 30 minutes before serving also helps it set.

  1. I’m confused as to what you do with the remaining 3/4 of the brown sugar?

    In step 2 you say mix 1/4 of the brown sugar with the plums, but what happens with the rest? Step 4 “sprinkle with more brown sugar (optional” is that where the rest of it goes?
