How to Select Plums

When you’re shopping for plums, keep these tips in mind from Whole Foods:

If you want to purchase plums that are ripe and ready to eat, look for ones that yield to gentle pressure and that are slightly soft at their tip. Good quality plums will feature a rich color and may still have a slight whitish bloom, reflecting that they have not been overhandled. They should also be free of punctures, bruises or any signs of decay. Plums are generally available in the marketplace from May through the early fall.

Plums that are not yet ripe can be left at room temperature. As this fruit tends to mature quickly, check on them in the next day or two to ensure that they do not become overripe. Once they are ripe, plums can be stored in the refrigerator for a few days. While plums can be frozen, to ensure maximum taste, remove their stone pits before placing them in the freezer.

  • Total Time: 1 hour
  • Yield: 15 bars 1x
  • Category: Dessert
  • Method: Bake



1 cup butter, cold, cubed
3 cups all-purpose flour
1 cup brown sugar
1 teaspoon baking powder
1 teaspoon cinnamon
1/4 teaspoon salt
large egg


45 large Black Plums (or other plum variety), chopped
1/2 cup granulated sugar
4 teaspoons cornstarch
1/4 teaspoon nutmeg


Preheat oven to 375 degrees. Spray a 9×13 inch baking pan with cooking spray or line with parchment paper for easy removal.

For the crust: In a medium bowl, stir together the flour, brown sugar, baking powder, cinnamon, and salt. Cut the cubed butter into the flour mixture with a fork or pastry cutter; add the egg and mix together. The dough will be crumbly. Pat half of it into the bottom of the prepared baking pan.

Filling: In a separate bowl, stir together the sugar, cornstarch, and nutmeg. Fold in the chopped plums. Sprinkle the plum mixture evenly over the bottom layer crust in the baking pan. Then crumble the remaining crust dough and spread over the plums.

Bake in preheated oven for 45 minutes, or until top is slightly brown. Cool completely before cutting into squares. Refrigerate to speed up the process!

    Could this be made omitting the egg?

      Although I’ve not made it without using the egg in the crumb portion of the recipe, I don’t see why it wouldn’t work. It may be a bit more crumbly without the egg to bind, but I know it would be delicious too!
