Mixed Berry Crumble

Updated: Feb 4, 2022

I love a good crumble, and this Mixed Berry Crumble is mighty fine. It's filled with the flavors of spring and summer, but with the use of frozen mixed berries it’s in season all year round. The berry filling is fruity and sweet with the perfect amount of tartness; the topping is nutty, naturally sweetened with maple syrup, and crumbly in the BEST way. I cannot wait for you to try this crumble!

Healthy Dessert or Sweet Breakfast - You Pick!

Fruity crumbles are my weakness, and this Mixed Berry Crumble is my favorite this time of year! Like a traditional berry cobbler, the filling is sweet and juicy with the perfect amount of tartness, but the topping is actually nutrient dense. This recipe has just enough sweetness to satisfy your sweet tooth, but is nourishing enough to have as part of a berry balanced breakfast.

  • For breakfast, pair with plain Greek yogurt or coconut skyr.

  • For a better-for-you dessert, pair with your favorite vanilla bean ice cream.

Whether you enjoy this naturally gluten free and vegan crumble for breakfast, dessert, or BOTH is up to you! And you really can't go wrong either way. I personally love making it ahead of time and reheating it for breakfast for the next few days. It's great meal prep recipe that makes busy mornings easier!

Nourishing Berry Crumble

With simple, shelf stable ingredients like heart healthy whole grain oats, omega-3 rich walnuts, and warm spices as well as immune supporting mixed berries, this Mixed Berry Crumble is easy-to-prepare, delicious, and packed with nutrition.

Old fashioned oats, mixed berries, walnuts, and shredded coconut all contain fiber which may help balance out blood sugars, promote fullness, reduce the risk of heart disease, and aid in digestion. Consuming foods that are rich in fiber is a great way to promote your health.

In addition to fiber, walnuts contain heart healthy ALA omega 3 fatty acids, polyunsaturated fats that may help to decrease LDL cholesterol (the bad kind) and total cholesterol levels.

Berries of all kinds are also rich in a variety of vitamins, minerals, and antioxidants. Sweet and juicy berries are a great addition to a healthful diet (and this crumble!) and may promote cell health and offer heart protective and cancer-preventive effects.

Support Your Health with Blueberries

Before we get into this delicious recipe, I want to share a few fun facts about one particular berry, and one of my favorites, in this Mixed Berry Crumble - blueberries:

  1. Blueberries are rich in antioxidants which help keep your cells healthy and may help to prevent brain and heart diseases as well as some cancers.

  2. Blueberries contain manganese, vitamin C, and vitamin K.

  3. Eating blueberries can help with blood sugar control due to the high fiber content (6g) and low sugar content (10g with no added sugar) compared to other fruits per serving (1 cup Wyman's Wild Blueberries). Fiber also aids in promoting fullness and bowel regularity.

  4. Frozen blueberries contain higher amounts of all nutrients compared to “fresh” ones from the store because they are flash frozen within 24 hours of harvest. I love Wyman's frozen Wild Blueberries and Triple Berry frozen mix with wild blueberries.

  5. Blueberries are super delicious!
