Fresh Blackberry Protein Overnight Oats

Packed full of fiber and protein, blackberry overnight oats are a satisfying option for breakfast or lunch on the go. Chia seeds make these overnight oats thick, creamy, and super filling. No added sugar, but they still taste decadent thanks to the sweetness from the protein powder and blackberries!

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 makes up the rest for quite a sweet treat.

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.

Cuisine: Canadian
Servings: 3 jars
Calories: 369kcal
Cost: $1.80 per jar


  • 1/2 pint blackberries 170g; see Note 1
  • 1 cup rolled oats 100g

  • 1/2 cup vanilla protein powder 45g; roughly 2 scoops


  • Add all except a small handful of blackberries to a small saucepan on medium heat. Cook for about 10 minutes, stirring occasionally and breaking apart the blackberries with your spatula, until mixture resembles a chunky jam.
  • Meanwhile, mix together the rest of the ingredients (oats, chia seeds, milk, protein powder) in a bowl.

  • Top with reserved whole blackberries. Chill for at least 2 hours before eating.

Recipe Notes

  1. 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.
  2. 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. Plus you will have less dishes to clean if you pour ingredients directly instead of measuring them out with a spoon or cup. When I was done, I only had to wash a saucepan, a bowl, and a spatula.
