Why I love this recipe:
No Bake – No heating up the house, and only takes 10 minutes to throw the ingredients together and put in the fridge.
Healthy – Nothing artificial here. These bars are filled with normal pantry ingredients and sweetened with honey.
Taste Delicious – I've had one to many unappetizing protein bars in my life, so I'm all about making them from scratch, with ingredients I recognize, and they taste wonderful!
Ingredients in Protein Bars:
- Rolled Oats – quick oats would also work.
- Protein Powder – Add your favorite whey or plant based protein powder including Chocolate, vanilla, or plain flavored.
- Peanut Butter – or substitute any nut butter or sunflower butter.
- Honey – Naturally sweetened and no added sugar. You could substitute agave.
- Ground Flax Seed
- Banana – mashed, for sweetness flavor and binding.
- Salt
- Vanilla Extract
- Mix-Ins – I like to customize my bars with chopped dates, dried fruit (blueberries, cranberries, or raisins), mini chocolate chips, or unsweetened coconut flakes.

How to make Protein Bars:
Combine Ingredients: Mix all ingredients in a large mixing bowl. Press firmly into an 8×8 inch pan.

Refrigerate for at least 1 hour before cutting into bars.

Cut into bars and store in the fridge.
Freezing Instructions:
Layer bars in a freezer safe bag or container, with a piece of parchment paper between layers, and freeze for up to 3 months. Thaw in the refrigerator or on the counter before eating.
Recipe Variations:
- Mix-Ins: Customize these bars with your favorite mix-ins! Some ideas: chopped dates, dried fruit (blueberries, cranberries, or raisins), mini chocolate chips, unsweetened coconut flakes, crispy rice cereal, chopped nuts, or anything you like!
- Nut Butter: Swap out the peanut butter for almond butter, cashew butter, or sunflower butter.
- Protein Powder: Use your favorite kind. Chocolate, vanilla, or plain would all work great for this recipe!
- Vegan Protein Bars Recipe: Use your favorite vegan protein powder.

Probably one of the best homemade bar recipes I’ve tried! Love them, and even my kids approve!
Since discovering your recipe I never buy protein bars again! Love how versatile the ingredients are. I often just use what is sitting in my cupboard and needs to be eaten. Also I mix whey protein with protein powders I bought that taste awful, to use them up. As I never have bananas in my house, I always replace it with applesauce and it tastes just as great. They last us for ~1,5 weeks. Also, I bake them at 160°C for 15 minutes or so – we like them even more this way. Thank you for the great recipe!
delicious and could scarcely be easier to prepare.
I made these according to the recipe. Then refrigerated them for 2 hours.
They were very sticky. After reading some of the comments below, I decided to bake them to see if that would change the texture. It did not.
So placed them back in the refrigerator in hopes they will be less sticky.
Truthfully I am very disappointed and would definitely not try them again and am going to hesitate trying any of the other snack recipes.
