💭 Why The Bars Work
Flavor: The protein bars are an easy vanilla peanut butter flavor that pairs well with everything.
Easy to make: With only 7 main ingredients, you probably already have everything you need, just like with this 3-ingredient Greek yogurt protein pudding.
Healthier than store-bought: Making your own protein bars means that you're in control of the sugar, additives, and protein. These are such a better-for-you option.
Ingredients and Substitutions

- Regular oats: Oats are an easy way to bulk up the recipe and stretch it further. Plus, they're a great source of recovery post-workout. Make sure to use rolled oats and not quick oats though, so that you retain some texture in your bars. And if you need them to be gluten-free, double check that.
- Vegan Protein Powder: The protein powder you choose will affect the flavor and the texture of the bars. This protein bar recipe with protein powder can be made with multiple types of protein.
- Peanut Butter: Use natural peanut butter to avoid unnecessary sugars and oils, or just make your own with this no oil peanut butter. This goes for Snickerdoodle protein bars, too.
- Plant-based milk: You can use any non-dairy milk you have on hand. I make mine with homemade hemp milk, but have done almond milk many times too.
See the recipe card for full information on ingredients and quantities.
Flavor Variations
Toppings: I like to drizzle my peanut butter protein bars with dairy-free chocolate glaze because, yum. However, any other toppings like nuts, sprinkles, or coconut work too.
Nut-free: Make these healthy protein bars nut-free by using sunflower seed butter in place of peanut butter.
Chocolate Peanut Butter: Made the bars chocolate by using a chocolate protein powder or adding in chocolate chips. Obviously, this is the best flavor combination ever, and even these protein buckeyes rock it.
How To Make The Vanilla Protein Bars Recipe
Before you start, learn everything you need to know about how to make homemade protein bars (step-by-step guide!).

Step 1: Combine the oats and protein powder.

Step 2: Whisk together the wet ingredients and add the mixture into the oats and protein powder. Stir before adding in the almond milk.

Step 3: Mix until combined and stocky.

Step 4: Press the homemade protein bars mixture into an 8x4 pan and freeze to set.
Expert Tips
The kind of protein you choose will adjust the taste and texture of the bars as well as how much liquid you need. Below are a few guidelines.
- Originally made with a fermented pea protein powder, which means the bars were a bit drier in nature and required more liquid and sweetener. If using a fermented protein powder, you'll want a full ¼ cup of non-dairy milk.
- If using a regular pea protein powder, the bars will be softer and sweeter. Add the milk in slowly and only as much as you need.
- As-written, the protein bars are made with beef isolate protein powder, which results in an ultra-sweet taste and stickier, delicious texture.
When pouring in the dairy-free milk, only add as much as you need to create a semi-sticky texture where everything holds together, but not too sticky that it gunks on your hands.
Give the bars a taste test before pressing them to see if you need a splash more sweetness, as some protein powders aren't sweet.
To make the protein bars vegan-friendly, use a pea protein powder and change the honey for coconut syrup to give the same texture.
How To Store Them
The homemade peanut butter protein bars can be stored in either the fridge or the freezer. In the fridge, they should last roughly 7 days. Whereas in the freezer, they'll stay fresh for about 1 month when stored in a freezer-safe container.
They do freeze pretty solid, so if they're in the freezer, make sure you let them thaw to room temperature before you're ready to eat them!
Likewise, if planning to store them in the freezer, make sure they are cut and separated into bars first and stored between sheets of parchment paper. Otherwise, you'll crumble them getting apart!
Peanut Butter Vanilla Protein Bars FAQs
Protein bars become crumbly when not enough oil and liquid are used. This especially happens with vegan protein powder as it absorbs so much. If you notice the batter crumbling as you mix it, add in a splash more milk, oil, or even nut butter until you get a stickier texture.
Protein bars, when made with minimal sugars and no processed oils, can be a healthy addition to any diet and a tasty way to increase daily protein intake.

- Add the almond milk last and very slowly, using only as much as you need to create a tacky texture.
- Tip: if you have specific dietary restrictions (gluten-free, dairy-free, vegan) – double-check all your ingredients for appropriate brands!
- Keep in mind the protein values may be off by 1-2 grams as it depends on which protein powder you’re using.
