Ingredients You’ll Need
These use simple pantry staples you likely already have at home.
- 1/2 cup old-fashioned rolled oats
- 1 scoop (30g) chocolate whey or casein protein powder
- 1 tablespoon unsweetened cocoa powder
- 1 tablespoon chia seeds
- 1/2 cup unsweetened almond milk
- 1/4 cup plain non-fat Greek yogurt
- 1 teaspoon maple syrup or liquid sweetener of choice
- 1/2 tablespoon dark chocolate mini chips
- 1/8 teaspoon sea salt
Step-by-Step
- In a wide-mouth mason jar or airtight container, whisk together the rolled oats, chocolate protein powder, cocoa powder, chia seeds, and sea salt until well combined.
- Add the almond milk, Greek yogurt, and maple syrup to the dry mixture.
- Vigorously stir the contents for at least 60 seconds to ensure the protein powder is fully hydrated and no clumps remain.
- Fold in the dark chocolate mini chips.
- Seal the container with a lid and refrigerate for a minimum of 4 hours, or ideally overnight (8 hours), to allow the oats and chia seeds to absorb the liquid.
- Before serving, remove the lid and stir thoroughly. If the consistency is too thick, incorporate an additional tablespoon of almond milk.
- Garnish with extra chocolate chips or a dollop of yogurt if desired and serve chilled.
Best Ways to Enjoy It
