This Simple Plum Crumble with Crunchy Walnut and Oat Topping is one of the easiest dessert recipes. You can’t go wrong with a crumble. No kneading, no shaping, no decorating. I usually make the crumble with a food processor, which is like 2 minutes tops. Interested?
So why plum crumble? It all started with a huge basket of plums (Italian Prune Plums aka Empress Plums) we received from my mother-in-law. Every year she makes tasty plum jams, plum pies, and plum dumplings, but there are always some extra baskets she has no time to preserve or use. So what should I do with them? My all-time favorite crumble is strawberry – rhubarb, but I thought cinnamon plum crumble sounds quite delicious. You might already be caught up on the fact that I love to use cinnamon. It just makes everything better, isn’t it? If you love it too, be sure to check out all of our cinnamon recipes.[Tweet “Have you heard of the quickest crumble dessert that is vegan and gluten-free.

Why crumble topping with oats and walnuts? Again, I have to thank the idea to my mother-in-law. A couple of years ago, she made these cute plum and walnut dessert bites. She made a large enough cut on the plum to take the seeds out and to put a larger walnut piece in the hole. After that, she dried them in a dehydrator/fruit dryer. When they were ready, she sprinkled them with granulated sugar. Yummm! They were so easy and so delicious. Plum and walnut just fit perfectly together. I was recalling this image and taste when I came up with the idea of this crunchy plum crumble topping with walnuts.
Plums are such underrated fruits, I think. The first thing that came up usually is that eating too many plums will have laxative effects.
However, plums are just extremely nutritious with high in Vitamin A, C and K and rich in antioxidants. If you’re interested to learn more, be sure to check out the seven evidence-based health benefits of plums.
Pair them with walnuts and you will get also an Omega-3 and Omega-6 rich dessert. Walnuts are exceptionally nutritious and not only rich in healthy fats, but fiber, minerals and vitamins as well. If your’re interested, you can read more about their health benefits.
Back to our Plum Crumble with Crunchy Walnut and Oat Topping and let me explain why this dessert is easier than any other. The most time-consuming part of this crumble recipe is to wash the plums and cut them in half to take the seeds out.
To make the plum crumble topping I took my food processor and mixed rolled oats, walnuts, dairy-free butter, coconut sugar, and some brown rice flour together under 2 minutes.
If you have all plum halves and your crumble topping, you are ready to layer them up. First, add plums and sprinkle them with cinnamon and sugar of your choice. Then cover them with your walnut oat topping. Now, bake it for 20 minutes.
Going the extra mile
After 20 minutes you have a crunchy, nutty and cinnamony plum crumble ready to eat. It is perfect with vanilla ice cream. Enjoy!
This Plum Crumble with Walnut Oat Topping is vegan, vegetarian and WFPB-friendly (whole foods plant-based). However, it is only gluten-free if you buy certified gluten-free rolled oats like this one. Oats are naturally gluten-free, although they are usually cross-contaminated with other grains. If you are interested to read more about oats, you can always visit the UK’s Coeliac Website.
