Step‑by‑Step Instructions for Easy Vegan Plum Crumble Cookie Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This step is crucial for ensuring that the Easy Vegan Plum Crumble Cookie Bars bake evenly. As the oven heats up, gather your 9-inch square baking pan and line it with parchment paper, letting it hang over the edges for easy removal later.
Step 2: Prepare the Plum Filling
In a medium mixing bowl, combine the chopped plums, 2 tablespoons of granulated sugar, cornstarch, and your chosen spices. Stir everything together until the plums are well-coated and the mixture is fully combined. You’ll know it’s ready when the plums have released some juices, creating a vibrant, glossy filling, perfect for layering in your cookie bars.
Step 3: Mix the Dry Ingredients
In another bowl, whisk together 2 cups of all-purpose flour, 1/2 teaspoon of baking powder, and a pinch of salt. This dry mixture is the backbone of your cookie base and crumble topping, so ensure it is evenly mixed. Once combined, set it aside to incorporate into the wet ingredients shortly.
Step 4: Cream the Butter and Sugar
In a large mixing bowl, cream together the Country Crock Plant Butter and 1 cup of granulated sugar until it becomes fluffy and light, which should take about 3-4 minutes. The mixture should look pale and airy. Next, add in the vanilla extract, stirring gently until everything is thoroughly integrated, adding to the richness of your cookie dough.
Step 5: Combine Wet and Dry Ingredients
Gradually mix the dry ingredient blend into the creamed butter and sugar mixture. Use a spatula to fold the ingredients together until a soft, slightly sticky dough forms. Be careful not to overmix, as this can lead to tough cookie bars. This dough will serve as both the base and the topping of your Easy Vegan Plum Crumble Cookie Bars.
Step 6: Form the Cookie Base
Take half of the cookie dough and evenly spread it into the lined baking pan, pressing down to create a solid base layer. This layer should be about 1/4 inch thick. Make sure the dough covers the entire bottom of the pan, as this will help support the juicy plum filling that will go on top.
Step 7: Add the Plum Filling
Spoon the prepared plum filling over the cookie base, spreading it evenly to ensure every bite is filled with that delicious fruity goodness. The filling should cover the entire surface of the dough, and its vibrant color will make your Easy Vegan Plum Crumble Cookie Bars incredibly inviting.
Step 8: Crumble the Remaining Dough
Take the remaining dough and crumble it over the plum layer, creating a topping that mimics a rustic crumble. Distribute it evenly, leaving some gaps for the plums to peek through. This final layer should be slightly chunky for a delightful texture and visual appeal.
Step 9: Bake to Perfection
Place the baking pan in your preheated oven and bake for 50 minutes. You’ll know the bars are done when the plum filling is bubbling and the crumble topping is golden brown. The enticing aroma will fill your kitchen, signaling that a delicious treat is on its way!
Step 10: Cool and Slice
Once baked, remove the pan from the oven and allow it to cool completely on a wire rack. Cooling is essential to help the bars set and make slicing easier. Once cooled, use the parchment overhang to lift the bars out of the pan and slice them into 16 squares for a perfect serving size of these Easy Vegan Plum Crumble Cookie Bars.

Make Ahead Options
These Easy Vegan Plum Crumble Cookie Bars are perfect for meal prep, allowing you to savor them throughout the week! You can prepare the plum filling up to 3 days in advance—just combine the chopped plums, sugar, cornstarch, and spices, then refrigerate it in an airtight container. The cookie dough can also be prepared and chilled for up to 24 hours. When you’re ready to enjoy your bars, simply assemble the layers and bake as directed. To maintain their quality, ensure you cool them completely before slicing and store any leftovers in an airtight container in the fridge for up to 5 days. You’ll have a delightful snack ready with minimal effort!

How should I store leftover cookie bars?

What should I do if the cookie bars are too crumbly when I slice them?
If you find your Vegan Plum Crumble Cookie Bars are crumbling too much while slicing, it might be due to a lack of cooling time. Ensure they cool completely on a wire rack before cutting.

Are these cookie bars suitable for those with gluten allergies?
To make your Vegan Plum Crumble Cookie Bars gluten-free, simply swap out the all-purpose flour for a 1:1 gluten-free flour blend. Make sure the blend includes xanthan gum to help maintain structure and achieve a similar chewy texture. Enjoy guilt-free baking!
Can my pets eat any of the ingredients?
