I know lemon blueberry is a real good combination for Spring and had been wanting to try something with that flavor profile for a couple of weeks now. And then it just so happened that Sprouts released a new Lemon Blueberry flavor Vegan Protein Powder, so…

NGL I was a little hesitant though since it was a Vegan protein powder, but damn was it good!? It was a very good surprise!

So here we are with these lemon blueberry protein bars that are VERY conveniently Vegan (just sub out the greek yogurt for coconut yogurt).

Why You’ll Love these Plant-Based Lemon Blueberry Bars

These Plant-Based Lemon Blueberry Protein Bars are simple, healthy and versatile too!

High Protein – You can already see that these bars have 6.4g protein per bar with only 70 calories!
Vegan & Dairy-Free – Made with plant-based protein and easily fully dairy-free
Low-Sugar & Weight Loss Friendly – With no added sugar and using a bit of a zero-calorie granulated sweetener, these lemon blueberry bars are great for weightloss!
Meal Prep Worthy – A great recipe to make as a snack for travels or post workout.

Ingredients

These lemon blueberry protein bars are made with a few healthy ingredients, and have no added sugars or butter either. Simple ingredients you can easily access.

Lemon Blueberry Protein Powder needed for protein bars, haha.
I use this protein powder from Sprouts to give it the perfect flavor, but you can always use vanilla as well. I recommend KOS or Truvani in that case.
Flour – I use 1:1 Gluten Free Baking Flour, but Whole Wheat Pastry Flour or regular All Purpose flour works here too.
1:1 Zero Calorie Brown Sugar Substitute – I use Lakanto to keep this recipe sugar free.
Lemon Zest – This really enhances the citrus flavor and freshness
Baking Powder
Nonfat Plain Greek Yogurt or Coconut Yogurt for some extra protein
Unsweetened Applesauce to provide moisture to the bars since protein powder can make it dry otherwise
Unsweetened Almond Milk
Cashew Butter
I recommend American Dream Nut Butter for a higher protein and slightly lower fat option. The link and code HAYLSKITCHEN gives you a discount!
Blueberries

Alternative Ingredients & Customizations

You can easily make these lemon blueberry energy bars you own with some of these alternatives.

I haven’t testing them all so I can’t say how your recipe might turn out. I’d love to know if you do though!

Protein Powder: Swap lemon blueberry protein powder for vanilla.
Be sure to use 2 tablespoon Lemon Juice with the wet ingredients, and reduce milk to 1 Tbsp.
Flour Options: All purpose flour, 1:1 Gluten Free Baking Flour or Whole Wheat Pastry Flour will work; Use the same amount by weight – 30g.
Zero Calorie Sweetener: Regular granulated sugar or coconut sugar can be used, but this won’t be sugar free, and also higher in calories.
Milk Options: Use any plant-based milk like oat, coconut, or cashew milk instead of almond milk.
Regular milk also works here
Cashew Butter: Almond Butter, Peanut Butter, Sunflower Seed Butter, Hazelnut Butter or even Tahini work well.

Dietary Restrictions

To make plant-based lemon blueberry protein bars dairy free: Use coconut yogurt.
For a Gluten Free version of homemade protein bars with blueberries, use 1:1 gluten free baking flour.

Flavor Options

Add on a cream cheese frosting like this recipe I have for a fun twist.
Swap out the blueberries for raspberries or even blackberries if you’d like!

How to Make Vegan Lemon Blueberry Protein Bars

Step 1: Preheat the Oven & Prep the Baking Pan

Preheat your oven to 350°F (175°C) and grease and line an 8″ x 4″ loaf pan with parchment paper.

Step 2: Mix the Dry Ingredients

In a large mixing bowl, whisk together the dry ingredients:
– Plant-based protein powder
– Flour
– Zero-calorie sugar replacement
– Lemon zest
– Baking Powder

Step 3: Mix the Wet Ingredients

Add in the wet ingredints:
– Greek yogurt (or dairy-free yogurt alternative)
– Unsweetened applesauce
– Almond milk
– Cashew or almond butter

If using vanilla protein powder, stir in lemon juice for the extra citrus flavor.

Step 4: Combine Wet & Dry Ingredients

Whisk gently until just combined. Be careful not to overmix to keep the bars soft and tender.

(Optional) Step 5: Prep the Blueberries

Place the blueberries in a bowl and toss them with a little extra flour—this prevents them from sinking to the bottom of the bars during baking.

Step 6: Fold in the Blueberries

Gently fold the blueberries into the batter, saving a few for topping.

Don’t mix too hard or you’ll crush the blueberries!

Step 7: Bake the Protein Bars

Spread the batter evenly into the prepared baking pan and top with extra blueberries.
Bake for 35-40 minutes.
The top should be set and a toothpick inserted into the center should come out clean.

Step 8: Cool & Slice

Let the bars cool in the pan for 15 minutes, then transfer them to a cooling rack.
Once completely cooled, slice into 8 bars.

Tips for perfect Lemon Blueberry Energy Bars

This lemon blueberry energy bars is a really easy recipe to make even though they have protein powder, but here’s some pointers to get it right.

Grease AND Line(with parchment paper) the pan; It just adds a little extra layer of surety so you know the bars won’t stick to the pan.
Whisk all dry ingredients well so everything mixes evenly.
Use smooth cashew butter so it mixes well with the rest of the ingredients and does not clump.
Taste the batter and see if you need some extra sweetener. I’d recommend using stevia powder to maintain the consistency of the batter and have healthy lemon blueberry bar recipe with no added sugar.
Toss blueberries in extra flour so they don’t stick to the bottom of the muffins when baking.

Equipment

I recommend using a good nonstick loaf pan for this recipe!

FAQs

Is it cheaper to make your own protein bars?

Yes! A store bought protein bar costs around $3-4 (in 2025 at least), but if you have all the ingredients on hand, you can make these at home for a lot less per protein bar!
