Plum Crumble Cookie Bars Ingredients

For the Plum Filling

  • Ground Ginger (optional) – Just a pinch can enhance the aroma; adjust to your taste preference.

For the Cookie Bars

  • All-Purpose Flour – The backbone of the cookie base; use a gluten-free blend if needed.
  • Baking Powder – Ensure it’s fresh to achieve the perfect rise in your cookie bars.
  • Salt – Important for a well-rounded flavor; don’t skip this step!
  • Country Crock Plant Butter® with Avocado Oil – Acts as the buttery base, providing rich flavor while keeping it plant-based.
  • Vanilla Extract – A must-add for enhancing the overall taste and aroma of the bars.

With these ingredients, your Plum Crumble Cookie Bars will shine, delivering a delectable summer dessert that everyone will love!

Step‑by‑Step Instructions for Plum Crumble Cookie Bars

Step 1: Preheat the Oven and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While it warms, take a 9-inch square baking pan and line it with parchment paper, allowing some overhang. This will help you easily lift out the delicious Plum Crumble Cookie Bars later. Set the pan aside, and get ready for the fruity filling.

Step 2: Prepare the Plum Filling
In a large mixing bowl, combine the chopped plums, granulated sugar, cornstarch, ground cardamom, and salt. If you choose to add ground ginger for an extra kick, mix it in now. Toss everything together thoroughly until the plums are well-coated. This creates a sweet-tart filling that will be nestled between the cookie layers. Set it aside to allow the flavors to mingle.

Step 3: Mix the Cookie Base and Topping
In another bowl, blend the all-purpose flour, baking powder, remaining sugar, and salt. Incorporate the melted Country Crock Plant Butter and vanilla extract into the dry ingredients, stirring until a soft dough forms. This dough will serve as both the base and the topping for your Plum Crumble Cookie Bars, so make sure it’s well-mixed and smooth.

Step 4: Form the Base Layer
Divide the cookie dough in half and press one half into the bottom of the prepared baking pan. Use your fingers or a spatula to spread it evenly, ensuring it covers the entire base. This base layer should be slightly firm, as it will support the juicy plum filling once it’s added.

Step 5: Add the Plum Filling
Evenly spread the prepared plum filling over the cookie base, ensuring that it covers the surface completely. The plums should be peeking out just a bit, adding a delightful visual appeal. This vibrant filling will bake beautifully and infuse the crust with flavor.

Step 6: Crumble the Topping
Take the remaining cookie dough and crumble it over the plum filling to create a topping. Aim for an even layer, allowing some plum filling to peek through. This will bake into a golden brown crumbly texture, which contrasts deliciously with the soft plum layer below.

Step 7: Bake the Bars
Place your assembled Plum Crumble Cookie Bars in the oven and bake for about 50 minutes. You’ll know they’re ready when the top is golden brown, and the filling is bubbling. Keep an eye on the edges to prevent over-browning; a nice golden hue is ideal for that perfect finish.

Step 8: Cool and Slice
Once baked, remove the pan from the oven and allow it to cool completely on a wire rack. This cooling stage is crucial for optimal slicing. Once cooled, use the parchment paper overhang to lift the bars out of the pan and slice them into 16 inviting squares. They are now ready to serve and be enjoyed by all!

Make Ahead Options

These Easy Vegan Plum Crumble Cookie Bars are fantastic for meal prep! You can prepare the plum filling and store it in the refrigerator for up to 3 days before baking to enhance the flavors. Additionally, the cookie base and topping can be mixed and refrigerated for up to 24 hours as well, simplifying your day-of baking. Just remember to bring the dough back to room temperature for easier handling before pressing it into the pan. When you’re ready to bake, simply assemble the layers and follow the baking instructions for a quick, delightful dessert that’s just as delicious as when made fresh!

Plum Crumble Cookie Bars Recipe FAQs

How do I choose ripe plums?
Absolutely! When selecting plums, look for fruits that yield slightly to gentle pressure, which indicates ripeness. You want them to feel firm but not hard—don’t shy away from plums with a slightly softer feel, as they are often sweeter and juicier.

How should I store leftover Plum Crumble Cookie Bars?
To keep your delicious bars fresh, store them in an airtight container at room temperature for up to 3 days. If you’d like to prolong their shelf life, pop them into the refrigerator for up to a week. Just remember to bring them to room temperature before serving for the best flavor!

Can I freeze Plum Crumble Cookie Bars?
Very! To freeze your bars, wrap them tightly in plastic wrap, followed by a layer of aluminum foil to prevent freezer burn. They can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw them in the fridge overnight. If you’re craving that fresh-baked warmth, microwave them for 10-15 seconds.

What if my bars crumble while cutting?
If your bars are crumbling too much while you slice them, it might be due to not letting them cool fully. Always allow your Plum Crumble Cookie Bars to cool completely in the pan before lifting them out with the parchment overhang. If they were still warm, the filling could seep, making them less stable during slicing.

Can I adapt the recipe for allergies?
Absolutely! To ensure the recipe is suitable for different dietary needs, use gluten-free flour in place of all-purpose flour if gluten is a concern. Additionally, for nut allergies, ensure that the Country Crock Plant Butter you choose is free from cross-contamination with nuts. Always double-check labels on ingredients like sugar and spices, as they can sometimes contain additives.

What toppings can I add to my Plum Crumble Cookie Bars?
The more the merrier! You can comparatively add nuts like walnuts or almonds in the crumble for a delightful crunch. A simple icing or a sprinkle of powdered sugar can enhance the sweetness—just adjust based on how indulgent you’d like them to be. Enjoy experimenting!
