Not kidding, I had no idea that blueberry and pumpkin was even a good combination, but man is it worth it?! The juicy summer berries and cozy fall vibes in the pumpkin come together so well in this recipe.

My husband and I had about 3 pieces at a time; Yes, that’s how good these are.

Ingredients for Blueberry Pumpkin Protein Bars

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

Pure Pumpkin Puree either from the can like libbys, or homemade. Make sure its not pumpkin pie filling though
Low Fat Pumpkin Spice flavored Kefir for an extra high protein pumpkin baked oats recipe. I used the one from Lifeway Kefir.
Vanilla Protein Powder needed for high protein blondies and also replaces most of the ‘sugar’.
I used the whey-casein Vanilla protein powder from Quest Nutrition and part plant-based vanilla from Livwell Nutrition.
Unflavored Protein Powder to replace some of the flour (and carbs) in the recipe for a slightly low calorie protein blondie. Quest Nutrition whey-casein again here.
Pumpkin Cheesecake flavored Peanut Butter Powder (peanut powder), or regular
I used Pumpkin Cheesecake Flavored PB Co peanut powder.
For a regular version I’d recommend Lakanto (code HAYLSKITCHEN gives you a discount) or PbFit or PB2 too.
Blueberries
Whole Wheat Pastry Flour
1:1 Zero Calorie Brown Sugar Substitute – I use Lakanto, to keep this recipe sugar free; (code HAYLSKITCHEN for a discount here).
Unsweetened Almond Milk
Almond Butter
I recommend American Dream Nut Butter Pumpkin Cheesecake, or any other Almond Butter here; Its lower fat and higher protein. The link or code HAYLSKITCHEN gives you a discount too.
Pumpkin Pie Spice
Baking Soda

Tips for perfect Bluberry Pumpkin Energy Bars

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

Whisk all wet ingredients well so its a smooth mix.

Use drippy almond butter so it mixes well with the wet ingredients and does not clump.

Don’t over-mix the batter!
Make sure you gently fold the dry mix into the wet to combine them.
If you over-mix it, the protein powder will make the low calorie blueberry pumpkin dessert bars tough, dense and gummy.
Toss blueberries in extra flour so they don’t stick to the bottom of the muffins when baking.

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 blueberry pumpkin spice bar recipe with no added sugar.

How to store Blueberry Pumpkin Spice Protein Bars?

This blueberry pumpkin spice protein bar keeps well for a meal prep dessert or post workout snack and is freezer friendly too!

Store pumpkin blueberry snack bars at room temperature in an airtight container for 1-2 days or in the fridge for a week.

To freeze healthy blueberry pumpkin squares, individually wrap each piece in plastic wrap and place in freezer-safe zipper bags or use air tight container; They should keep for 2-3 months. Thaw before eating.
