It's that time of year again for us. There is plenty of fresh fruit available. We can find a nice selection at fruit stands, grocery stores, and our back yard. Today I decided to try something a little different by making a plum dessert. This is my recipe for Plum Oatmeal Crisp. A little bit sweet, a little bit tart, and a lot delicious!
This post was updated in July of 2021 with a few new photos.
We have several fruit trees. This year we didn't get many cherries, but we have had a ton of apricots and plums. Next up will be the peaches!
I really have not worked with plums much, and this is the first plum recipe I have added to my site. We usually eat the plums just picked from the tree. This year we have way too many to do that. Hopefully, I will be able to add more plum recipes. I have a couple of ideas going through my mind already.

Not only are plums nutritious, but they are also pretty tasty. Although, the squirrels still seem to prefer to eat the apricots! I guess I will be making several plum desserts and other plum recipes.
Ingredients needed
To make this recipe for Plum Oatmeal Crisp you need,
- Plums
- Granulated sugar
- Lemon juice
- Cornstarch
- Cinnamon
- Old fashioned oats
- All-purpose flour
- Brown sugar
- Butter or margarine
How to prepare this recipe
First of all, get the plums ready. Rinse them off and let drain. Next, you need to cut them up into large bite-size pieces. I just cut around the pit. You need 6 cups of fruit, for us that was about 30 plums.
Here are the diced plums that I immediately coated with lemon juice. In the other bowl is the cornstarch, sugar, and cinnamon that I have mixed together. Add the sugar mixture to the plums and stir well to combine.
Coat a baking dish with non-stick spray and pour in the plum and sugar mixture. Now it is time to prepare the crumb topping.
Mix together the brown sugar, oatmeal, cinnamon, and the flour. Add the butter or margarine that has been cut into pieces. Use a fork, pastry blender, or your hands to create the topping.
Sprinkle the topping over the plums and now the Plum Oatmeal Crisp is ready to bake. Place it in the oven for 35 - 45 minutes, until the plums are bubbly and the top is golden brown.
Let cool a bit before digging in. The longer you let it cool down the thicker it will be. But, when it is warm it is awesome with some vanilla ice cream or vanilla frozen yogurt.
Tips for using fresh fruit
- It's hard to predict the sweetness of fresh fruit until you taste it. Adjust the sugar to your liking. Especially if you prefer a sweeter plum dessert. On this particular batch of plums, some of them were sweet and some were tart. The finished product was a little tart, but I really like it that way myself.
- As with sweetness, it is also hard to predict how juicy the fruit will be until you start to cut into it. Likewise, you might need to adjust the amount of cornstarch you use to thicken it up. With this batch, I used 2 tablespoons of cornstarch, but I could have probably just as easily used 3.
- I store my crisp on the kitchen counter for the first day. However, if it is really hot weather, or longer than a day, I will keep it in the refrigerator. Use your best judgment. You can always warm up a serving in the microwave.

Great dessert, but just wanted to point out a mistake in topping instructions. It didn’t throw me but it could someone. In the topping instructions you said combine flour, cornstarch, cinnamon and sugar then cut in the butter. Should have said oats, not corn starch!
Thanks again for this recipe tho, very good!
