Gather all of the ingredients and place them on a clean countertop or work surface before you begin. Having everything measured and ready makes the process smoother and helps ensure the ingredients are mixed properly without missing anything.
Add the Greek yogurt to a medium mixing bowl and whisk it briefly until it becomes smooth and creamy. This step helps remove any lumps and creates a uniform base for the pudding.
Slowly pour the unsweetened almond milk into the bowl with the yogurt while whisking continuously. Continue mixing until the yogurt and milk are completely combined and the mixture looks smooth and evenly blended.
Add the vanilla extract to the bowl and stir it into the mixture. If you prefer a sweeter pudding, add your honey, maple syrup, or preferred sweetener at this stage and whisk until fully incorporated.
Gradually add the vanilla protein powder a little at a time while whisking continuously. Adding it slowly helps prevent clumps from forming and ensures the powder blends smoothly into the liquid.
Continue whisking until the protein powder is completely dissolved and the mixture has a smooth, creamy consistency. Scrape down the sides of the bowl if needed to make sure everything is evenly mixed.
Sprinkle the chia seeds evenly across the surface of the mixture rather than pouring them into one spot. This helps prevent them from sticking together and forming large clumps.
Whisk thoroughly for about one minute, making sure the chia seeds are evenly distributed throughout the mixture. The mixture should look uniform, with the chia seeds suspended evenly in the liquid.
Add most of the mixed berries to the bowl, reserving a small handful for topping later. Using both whole and slightly broken berries adds natural sweetness and distributes berry flavor throughout the pudding.
Gently fold the berries into the mixture using a spatula or spoon. Stir carefully so the berries are incorporated without being crushed too much, which helps maintain texture and visual appeal.
Allow the mixture to rest at room temperature for about 5 minutes. During this time, the chia seeds will begin absorbing liquid and start the thickening process.
After the resting period, stir or whisk the mixture again thoroughly. This second mixing step is important because it breaks up any chia seed clusters that may have formed and helps create a smoother final texture.
Divide the mixture evenly between two mason jars, glass containers, or airtight meal-prep containers. Fill each container carefully so the portions are approximately equal.
Secure the lids tightly on each container to prevent the pudding from absorbing refrigerator odors and to keep it fresh during chilling.
Place the containers in the refrigerator and chill for at least 4 hours. For the best texture and flavor, allow the pudding to sit overnight so the chia seeds can fully absorb the liquid and create a thick, creamy consistency.
When ready to serve, remove the containers from the refrigerator and check the texture. If the pudding seems too thick, stir in a small splash of almond milk until it reaches your preferred consistency.
Top each serving with the reserved mixed berries, arranging them evenly over the surface for added freshness, color, and flavor.
Serve cold and enjoy as a protein-packed breakfast, post-workout snack, meal-prep option, or healthy dessert. The creamy texture, juicy berries, and high protein content make it both satisfying and delicious.
