Equipment

  • 16-ounce wide-mouth mason jar

Ingredients
  

For each jar you will need:

  • 1/2 cup rolled oats
  • 1 tbsp chia seeds
  • 1 scoop unflavored protein powder (30g)
  • 1/3 cup plain Greek yogurt
  • 1/2 cup milk of choice
  • 1-2 tbsp pure maple syrup
  • 1 pinch salt
  • 1/2 cup frozen berries

For the flavor twist:

  • 1 tablespoon mixed berry jam
  • 1/4 teaspoon fresh lemon zest

Instructions
 

Combine and Shake

  • In a 16-ounce wide-mouth mason jar, add the rolled oats, chia seeds, protein powder, Greek yogurt, milk of choice, pure maple syrup, a tiny pinch of salt, the mixed berry jam, and fresh lemon zest.
  • Secure the lid tightly. Give it a vigorous shake for about 30 seconds to ensure no dry clumps remain and everything is well combined, creating a smooth texture.

Add Berries and Chill

  • After combining, remove the lid and gently place the frozen mixed berries on top of the mixture. Avoid stirring them in, as they will naturally thaw and release their juices overnight.
  • Replace the lid and refrigerate the jar for at least 6 hours, or ideally, overnight, allowing all the flavors to meld and the oats to soften.

Stir and Serve

  • When morning arrives, open your jar and give the oats a good stir. You'll notice how the berries have thawed and their juices have started to blend with the oats.
  • If the mixture is too thick for your preference, simply add a small splash of your preferred milk and stir until you reach your desired consistency. Enjoy these oats straight from the fridge, perfectly chilled!

Notes

Ingredient Insights: Use rolled oats for a chewy texture, as instant oats can get mushy. Whey protein generally results in a thinner mixture, while casein or plant-based proteins can make it thicker, possibly requiring milk adjustment. Frozen berries are preferred over fresh as they release more juice and flavor when thawing overnight. Greek yogurt and chia seeds are crucial for thickness and creaminess; for a vegan option, use dairy-free yogurt.
Meal Prep & Storage: These oats are perfect for meal prep; make several jars at once and store them in airtight containers in the refrigerator for up to 5 days.
Texture Tips: For the ideal pudding-like texture, ensure you use chia seeds and Greek yogurt. If your oats are too thick, add a splash of milk; if too thin, it might be due to skipping chia seeds or yogurt, or using too much liquid initially.
Flavor Enhancements: Adding a small pinch of cinnamon or cardamom can subtly complement the berry flavor. Always taste and adjust sweetness or consistency in the morning.
Serving Suggestions: Enjoy cold from the refrigerator. For added texture and flavor, top with hemp seeds, toasted coconut flakes, granola, chopped almonds, a dollop of yogurt, or a drizzle of maple syrup just before serving.
Pro Tip: To prevent clumping, add milk to the jar first, then protein powder, and finally the remaining ingredients before shaking vigorously. Save crunchy toppings for serving to avoid sogginess.
