This high-fiber, high-antioxidant delight is simply irresistible! This nourishing berry crumble is one of my favorite desserts because it satisfies that afternoon sweet tooth. Yet, it’s sweetened with fructose, a natural fruit sugar. With the perfect blend of sweetness, crunch, and bursts of blueberry and strawberry flavor, it’s tempting to classify it as dessert, just like my Chocolate Bounty Blueberry Bites or my Raspberry and White Chocolate Blondie.


However, it doubles effortlessly as a satisfying afternoon sweet snack, especially with a nice hot cup of tea, or if you prefer it makes a revitalizing breakfast option. Baking fresh berries enhances their flavor, making them even more delicious and juicy. So, pick up some fresh berries from your local market, and let’s get baking!

FAQs


Are bananas classified as berries?

Yep, bananas are classified as berries! They fit the botanical definition because they develop from a single flower with one ovary and contain seeds inside. So, even though we don’t usually think of them as berries, they technically are.

Can I use frozen berries instead of fresh ones?

Absolutely! You can use frozen berries instead of fresh ones in many recipes. Just remember that frozen berries may release more moisture as they thaw, so you might need to adjust the recipe slightly to account for this.

Can I make the crumble topping sweeter?

You can sweeten the crumble topping with the syrup of your choice.

Can I substitute ground flaxseeds for whole flaxseeds?

Yes, you can but whole flaxseeds have a toucher outer hull and are much more difficult to digest.
