What are the health benefits of blackberries? They are often one of the most overlooked berries in the berry family. However, these tiny black sweet jewels are full of nutrients. Blackberries are rich in vitamin C, which can help support a healthy immune system.

Blackberries have been touted as the “gout berry” for their curative nation of the illness, gout. They are also important for the healthy cognitive function of the brain. Studies have shown a decrease in Alzheimer’s disease progression due to the high anthocyanin content (1).

They also have moderate fiber content. Blackberries contain antioxidants which are fantastic to protect against free radicals that can otherwise cause disease in the body. One cup of blackberries is around 62 calories. In addition, they have a low glycemic index (GI) of only 25.

They have a mild tart and sweet flavor that makes them perfect for pie recipes and tarts. Blackberries are fantastic in salads and smoothie recipes.

Blackberries are a perfect berry to freeze and use later. They hold up their shape and will last for about 2-3 months in the freezer. Fresh blackberries tend to last about 4 to 7 days in the refrigerator.

Can I use different fruit in these pie bars?

Yes, test out any other tasty berries you like. Personally, this recipe is equally delicious with strawberries or blueberries. You can make a simple blueberry pie bar or even an apple pie bar recipe. I encourage you to experiment with various flavor profiles.

Can I use frozen berries for this recipe?

You can make this with fresh, or if you have frozen berries from your summer harvest, that would be perfect too. I do suggest you thaw the frozen berries first.

What can I substitute for the honey?

You can substitute the honey for maple syrup or even molasses. . This will also make the recipe vegan.

What do you suggest for making the filling sauce less seedy?

I suggest putting the sauce filling mixture through a fine mesh sieve if you dislike the seeded texture from the blackberries.

Can I use frozen blackberries for this pie crumble bars recipe?

Yes, you can substitute with frozen blackberries. The texture will change a bit, but it’s still delicious.

Can I use a blender if I don’t own a food processor?

Yes, however, you will have some difficulty removing the crust from the blender. I suggest you use a spatula to scrape the mixture from the blender.

Can I use almond meal instead of almond flour?

The topping of these pie bars is meant to be crumbly, so you can definitely use almond meal instead of the flour. Almond flour is made from blanched (peeled) almonds, so it is lighter in texture. The almond meal has a coarser consistency and adds more fiber. Other than that, the nutritional content is the same. There are more antioxidants in the almond meal due to the skin remaining. This will result in a slightly denser crust, but if you dislike the crumbly texture, simply add in more liquid. I suggest adding a tablespoon more coconut milk.

How to Store, Freeze, and Thaw Blackberry Squares:

Store any leftover vegan crumble bars in an airtight container in the fridge for 3-4 days. You can freeze your blackberry square bars layered between parchment paper in an airtight container for up to 2 months. Simply thaw, by removing from the freezer and allowing them to come to room temperature, takes 3-4 hours or even thaw overnight in the refrigerator. This recipe makes the perfect vegan breakfast bars to take on the go.
