Looking for a simple, creamy, protein-rich treat that also gives you a delicious way to use your sourdough discard? These Blueberry Protein Yogurt Bites are a fun option for sourdough bakers who don’t want their discard to go to waste.
They combine creamy Greek yogurt, blueberries, sourdough discard, and protein powder to create little frozen bites with a beautiful blueberry swirl. They’re refreshing, easy to prepare, and perfect for breakfast, an afternoon snack, or a light dessert.
The original idea is similar to frozen yogurt bites, but adding sourdough discard gives the recipe a subtle tangy flavor and makes it especially suitable for a sourdough recipe collection.
Ingredients
- 1 cup (240 g) plain Greek yogurt
- ½ cup (120 g) active or unfed sourdough discard
- ½ cup fresh or frozen blueberries
- 1 scoop vanilla protein powder
- 1–2 tablespoons honey or maple syrup, optional
- ½ teaspoon vanilla extract
- 1 tablespoon milk, if needed
- 1 tablespoon chia seeds, optional
- A few extra blueberries for topping
Why Use Sourdough Discard?
Sourdough discard is the portion of starter that many bakers remove before feeding their starter.
Instead of throwing it away, you can use it in recipes such as pancakes, crackers, muffins, waffles, cakes, and other creative treats.
In this recipe, the discard contributes a mild tanginess that pairs nicely with sweet blueberries and creamy yogurt.
For the best texture, use a sourdough discard that has been properly maintained and stored. If your discard has an unpleasant smell, visible mold, or unusual discoloration, do not use it.
Preparing the Blueberry Mixture
Start by placing the blueberries in a small saucepan.
If using fresh blueberries, rinse them first. Frozen blueberries can be used directly.
Cook the blueberries over low to medium heat for approximately 3–5 minutes, stirring occasionally.
As the berries warm, they will soften and release their natural juices.
Use the back of a spoon to gently mash some of the berries while leaving a few pieces whole.
Remove from the heat and allow the blueberry mixture to cool completely.
You can also use fresh blueberries without cooking them, especially if you prefer a more natural fresh-fruit texture.
Making the Protein Yogurt Base
In a large mixing bowl, add the Greek yogurt, sourdough discard, vanilla protein powder, vanilla extract, and optional honey or maple syrup.
Stir until the mixture becomes smooth and creamy.
If the mixture seems too thick, add approximately one tablespoon of milk and stir again.
The final mixture should be thick enough to hold its shape but smooth enough to spoon easily.
Taste the mixture before adding the blueberries.
If you prefer a sweeter bite, add a little more honey or maple syrup.
Remember that some protein powders are already sweetened, so you may not need additional sweetener.
Creating the Blueberry Swirl
Add the cooled blueberry mixture to the yogurt base.
Don’t completely mix the blueberries into the yogurt.
Instead, gently swirl them through the mixture using a spoon or spatula.
This creates beautiful purple and white swirls throughout the bites.
For an extra blueberry flavor, gently fold in a few whole blueberries.
If you’re adding chia seeds, stir them into the mixture at this stage.
Filling the Mold
Prepare a silicone mini muffin mold or small silicone candy mold.
Silicone molds work particularly well because the frozen bites can be removed easily.
Spoon the yogurt mixture into each cavity.
Fill each section almost to the top, leaving a small amount of space.
Add one or two blueberries to the top of each bite if desired.
Gently tap the mold against the counter to remove large air pockets.
Freezing
Place the filled mold carefully into the freezer.
Freeze for approximately 3–4 hours, or until the bites are firm.
For the best texture, allow them to freeze completely before removing them from the mold.
Once frozen, gently push each bite out of the silicone mold.
If they feel too firm, allow them to sit at room temperature for approximately 2–5 minutes before eating.
Storage
Transfer the frozen bites to an airtight freezer-safe container or reusable freezer bag.
Place parchment paper between layers if you are stacking them.
They can be stored in the freezer for approximately 2–3 weeks for the best quality.
Because the recipe contains yogurt and fresh fruit, keep the bites frozen and do not leave them sitting at room temperature for extended periods.
How to Make Them Creamier
For an extra creamy texture, use full-fat Greek yogurt.
For a lighter version, low-fat Greek yogurt can be used.
The protein powder also affects the texture. Different protein powders absorb different amounts of moisture, so you may need to add a small splash of milk if your mixture becomes too thick.
Avoid adding too much liquid because the bites need to freeze firmly.
Flavor Variations
Strawberry Protein Yogurt Bites
Replace the blueberries with chopped strawberries for a bright, fruity variation.
Raspberry Yogurt Bites
Use raspberries instead of blueberries for a slightly more tart flavor.
Mixed Berry Bites
Combine blueberries, raspberries, and strawberries for a colorful mixed-berry version.
Lemon Blueberry Bites
Add a small amount of fresh lemon zest to the yogurt mixture. Lemon pairs beautifully with blueberries and sourdough’s mild tang.
Chocolate Berry Bites
Add a small amount of unsweetened cocoa powder to the yogurt mixture for a chocolate-blueberry combination.
Serving Ideas
These little bites are especially good for breakfast or a quick snack.
Serve a few alongside fresh berries and a cup of coffee or tea.
They can also be packed into a freezer-safe container for a convenient make-ahead snack.
For a dessert-style presentation, place the bites in a small bowl and garnish with fresh blueberries and a little lemon zest.
Are These High Protein?
The exact protein amount depends on the Greek yogurt, protein powder, sourdough discard, and serving size you use.
Because protein powders and yogurt brands vary considerably, it’s better to calculate the nutrition using the exact products in your kitchen rather than assuming a specific protein number.
If you want a higher-protein version, choose a Greek yogurt with a higher protein content and a protein powder that fits your dietary preferences.
Frequently Asked Questions
Can I use active sourdough starter?
Yes. Active sourdough starter can be used, although unfed discard works well too.
Can I use sourdough discard straight from the refrigerator?
Yes, provided the discard has been properly stored and is fresh enough to use.
Letting it sit for a few minutes before mixing can make it easier to combine with the yogurt.
Do I have to cook the blueberries?
No. You can use fresh blueberries directly. Cooking them creates a softer blueberry swirl and releases more juice.
Can I use frozen blueberries?
Yes. Frozen blueberries work very well. Allow cooked berries to cool before mixing them into the yogurt.
Can I use a regular muffin pan?
Yes, but silicone molds are easier to use because the frozen bites release more easily.
If using a metal muffin pan, line it with small paper liners.
Can I make these without protein powder?
Yes. Protein powder is optional from a texture standpoint, although removing it will reduce the protein content.
You may need to adjust the amount of yogurt depending on the consistency.
Important Sourdough Note
Because these are frozen yogurt bites rather than a baked sourdough recipe, the sourdough discard is being used primarily for flavor and discard utilization.
The recipe should not be considered a traditional fermented sourdough product.
If you’re making these specifically for a sourdough community, highlighting the sourdough discard aspect in your post makes the recipe more relevant to the group.
