How to Make Better & Cheaper Protein Bars at Home

Tired of spending money on protein bars that look (& sometimes taste) like a piece of you-know-what? With the help of my taste-testing family (and lots of failed attempts), I’ve learned how to make protein bars at home that taste better and are a lot cheaper than prepackaged ones we buy.

Have you ever been in an airport or grocery store looking for a healthy and convenient snack and wandered over to the protein bar aisle? There are dozens of carefully-concocted bars that have just the right “macros”, are shelf-stable, and come in mouth-watering flavors like “chocolate chip cookie dough” and “peanut butter pie.” Follow-up question: How many times do the bars actually taste like chocolate chip cookie dough?

I hope you’ve been lucky enough to find a delicious protein bar on a store shelf. More often than not, I’m disappointed in whatever flavor (maple-glazed-donut comes to mind) I choose. Also, I’m spending more time at home lately, I also hate creating a wad of trash every time I eat a protein bar. Since I have all the ingredients to make something tasty, less expensive, and garbage-free – well, I decided to do it.

What makes this protein bar recipe work:

1. You Only Need a Bowl, a Fork, and a Spatula.

You need a medium-large bowl, a fork, and a spatula. Maybe a tablespoon, too. That’s it.

2. Only Six Ingredients

Five of the six ingredients are “normal” foods, and there’s no added sugar.

Protein powder is the exception to the “normal” food list. Yes, it’s processed, but you know what? I can live with that because it has high quality, easy-to-digest protein and lots of muscle-building branched-chain amino acids (BCAAs) (especially important for athletes and injury recovery). And, it is a milk protein product, so it isn’t totally manufactured.

All six ingredients, and the vanilla is optional. So really, only FIVE ingredients!

Side note: Heating whey protein may change the protein through the denaturing process, but this will not make it less nutritious or decrease its benefits to your health

3. Good Cocoa or Cacao Powder

The key to a deep chocolate flavor is high quality cocoa powder. My all-time favorite is the Eat Well Cacao Powder.

4. Flavored Whey Protein Powder

Flavored whey protein powder adds protein, sweetness without actual sugar, and a bit of flavor. I like ON’s Gold Standard Whey in vanilla ice cream flavor. However, I’ll bet chocolate, cookies ‘n’ cream, and similar varieties would taste great, too.

5. Dark Semi-Sweet Chocolate Chips

A little goes a long way! Two tablespoons of semi-sweet chocolate chips are all we need to boost the YUM factor on this recipe.

6. Cottage Cheese

Wait, what?! Yep, and here’s why.

  • First, it has a lot of protein. In this recipe, cottage cheese alone ads 26 grams of protein, or around 4 grams per bar.
  • Second, it has rich and salty flavor, so you don’t have to add any salt.
  • Third, it has some fat, which makes the bar more tender on the inside and smoother in your mouth. Along those lines, the curds melt when baking and add an interesting variation in texture.
