These Chocolate Whey Protein Bars are easy to make at home for a high-protein snack. They’re gluten-free, nut-free, and no-bake. Plus, they’re drizzled with melted dark chocolate for extra indulgence.

You can make the recipe into four or six bars, depending on your preference. When divided into six, each bar contains 191 calories and just over 14 grams of protein. For a higher dose of protein, you can divide the mixture into four larger bars with 287 calories and just over 21 grams of protein. I sweeten the bars with brown rice syrup, but if you wanted to reduce the calorie content you could use a sugar-free syrup sweetener instead.

Benefits of homemade protein bars

Making your own homemade protein bars allows you to control what goes into them. This give you the benefit of tailoring the bars to suit your needs.

First, you can choose to use a high quality protein powder. I usually use a grass-fed whey protein isolate. For this recipe, I used a chocolate whey protein powder that isn’t heavily sweetened. Alternatively, you could use unflavored and unsweetened whey, since the recipe includes some sweetener and cacao powder.

Second, you can adjust the type of sweetener used to meet your requirements. You can use a liquid sweetener such as brown rice syrup, maple syrup or honey. Or, if you need to keep your sugar intake to an absolute minimum, you could use a liquid sugar-free sweetener.

Third, you can customise the flavor. Even though I use a chocolate whey protein powder in this recipe, I like to add some extra raw cacao powder for a more intense chocolate taste.

Is it cheaper to make your own protein bars

It is usually cheaper to make your own protein bars as they cost less per bar than store-bought options.

Despite the upfront cost of ingredients, you can make multiple bars from them at a lower overall cost.

This is especially true when comparing homemade bars to higher-quality, more expensive store-bought varieties.

Ingredients for chocolate whey protein bars

Chocolate whey protein powder: I like to use a chocolate grass-fed whey protein isolate. But whey protein concentrate or a blend will also work if that’s what you have at home. You can also use unflavored whey protein, since the recipe includes cacao powder and some sweetener.
Oat flour: You can make your own oat flour by blending rolled oats in a blender or food processor until you get a flour consistency. It helps to firm up the texture of the protein bars.
Raw cacao powder: To increase the chocolate flavor of the protein bars, I add some raw cacao powder to the recipe. Regular cocoa powder will also work as a substitute.
Coconut flour: When blended with the oat flour, a little bit of coconut flour gives the bars structure.
Coconut oil: A small amount of coconut oil helps the protein bars set firm when chilled. It also improves the texture.
Brown rice syrup: I use brown rice syrup to add extra sweetness to the bars, in addition to the sweetener in the chocolate protein powder. You can substitute maple syrup, honey or a sugar-free liquid sweetener if you prefer.
Water: Some water is needed to help the whey protein powder blend with the other ingredients. You could also use your favorite milk as a substitute.
Dark chocolate: I love to drizzle melted dark chocolate over the protein bars as an extra treat. It also provides textural contrast.

How to store whey protein bars

Since water is added to these whey protein bars, it’s best to store them in an airtight container in the fridge for up to 3 days.

You can freeze any extra bars that you won’t eat within this time frame. They can be defrosted in the fridge overnight as needed, or let them soften at room temperature before eating.
