Plum Crumble Bars

There are just too many summer fruits, and we often overlook some of them. We tend to focus on those giant watermelons and pineapples. But what about plums? In the United States, you can see plums everywhere from May to October, especially in California. In fact, this state is the biggest producer of plums. So if you go to the grocery, you will most likely see Californian plums.

Just so you know, the varieties also grow and ripen at different months. If you are wondering if you can get plums all year round, the answer is yes!

So, what’s with plums? Well, these tiny fruits are sweet and tangy. They have this beautiful reddish-blue skin that gives color during the monsoon season. But do you know what’s so great about plums? They are loaded with vitamins, minerals, as well as antioxidants. They are also low in calories, which is why you can incorporate them into your diet even if you are trying to lose weight.

Plums make a good dessert, too. Have you ever had Plum Crumble Cars? If not, OMG, you are missing half of your life! These delightful bars are so delicious. Once you have one, you will never neglect plums ever again!

These bars will certainly put plums to good use – which they truly deserve. With buttery crusts and the distinct taste and texture of plums, you will have the most delightful snack or dessert with Plum Crumble Bars!



For the crust and crumble:

2 c. all-purpose flour

1/2 tsp. baking powder

1/4 tsp. salt

1 c. butter (with avocado oil)

1 c. granulated sugar

1 tsp. vanilla extract

For the filling:

3 c. chopped plums

2 tbsps. granulated sugar

2 tbsps. cornstarch

1 tsp. ground cinnamon

1/2 tsp. ground ginger

a pinch of salt


  1. Make the filling first by tossing plums with sugar, cornstarch, salt, and spices. Set aside.
  2. Preheat oven to 350 degrees Fahrenheit and line a 9-inch square baking pan with parchment paper.
  3. Combine flour, salt, and baking powder in a medium bowl and set aside.
  4. Mix the butter and sugar in a separate bowl until light and fluffy. Beat in the vanilla.
  5. Set the mixture on low and slowly add the flour mixture. Mix until just combined.
  6. Set aside about 3/4 cup of the dough. Firmly press the remaining into the prepared pan and then evenly spread the plum mixture over the crust. Crumble the reserved dough over plums.
  7. Bake for about 45 to 50 minutes or until the top is golden and the filling is bubbling.
  8. Transfer the pan to a wire rack and cool completely.
  9. Grab the ends of the parchment paper and take the crumble out of the pan. Slice into 16 bars. Serve.


  • For the butter, I highly recommend Country Crock Plant Butter.
  • When lining the baking pan, be sure to have the ends of the parchment paper overhang on two sides so that it will be easier for you to lift the bars out later on.
  • Prep Time: 20 minutes
  • Cook Time: 50 minutes

If you can find Country Crock Plant Butter, that would be much better. It is plant-based and it serves as a great alternative to regular butter. Plus, it makes these Plum Crumble Bars more delicious. I can guarantee you, these bars are the real deal!
