  1. Add all except a handful of the blackberries to a small saucepan on medium heat. Heat for about 10 minutes, stirring occasionally and breaking apart the blackberries with your spatula, for about 10 minutes or until mixture resembles a chunky jam.
  2. Meanwhile, thoroughly combine the rest of the ingredients (oats, chia seeds, plant milk, protein powder) in a mixing bowl.
  3. Spoon a layer of the bowl mixture into the bottom of each mason jar. Follow by spooning in a layer of the blackberry mixture. Repeat this layering until all the ingredients have been used up.
  4. Top with the remaining blackberries.

Recipe notes

Although I’ve provided volume approximations for the ingredients, I always weigh my items on a food scale for my recipes. So, following the weight measurements will yield the best results.

What if I don’t have blackberries?

The sky is the limit on your fruit choices. You can just as easily sub blueberries, raspberries, strawberries, or any other soft juicy fruit into these protein overnight oats. That goes for frozen fruit, too!

For larger fruits like strawberries, just make sure to slice them first before tossing them in the saucepan, to help them break down faster.

Overnight oats—the ultimate grab-and-go meal

I love oats for their simplicity and versatility. Anyone can whip up a batch of overnight oats and have it taste delicious the next day—it’s amazingly hard to screw up.

This blackberry concoction has been one of my favourites because not only is it delicious and filling with all that fiber and protein, it’s also sugar-free. Heating the blackberries up into a puree releases a lot of their natural sugar, and the little bit of sweetness from the protein powder combines

I’ve been eating these protein overnight oats throughout the past week, not only for breakfasts but even sometimes at lunch when I don’t have much time between classes to come home and make a sit-down meal.
