These homemade oatmeal protein bars pack 8 grams of natural protein per serving without any protein powder or added sugar! Made with just 6 simple ingredients, they’re the perfect healthy snack that takes minutes to make and stores for weeks.
Confession: my weakness when it comes to packaged foods is my favorite protein bars. But after reading the ingredients list one day, I decided it was finally time for a homemade version of them! After many recipe tests this what I came up with, and I’m obsessed.
These homemade oatmeal protein bars have ~8 grams of protein per serving with no protein powder. The protein comes naturally from almond flour and roasted peanuts, and Medjool dates add sweetness. After testing countless variations, this recipe has become my go-to! I love that the bars taste like oatmeal cookies but pack actual nutritional value. Alex and I try to make a batch as healthy snacks every week—even the kids ask for these instead of store-bought granola bars!
Simple ingredients that pack a punch
For this recipe, I tried to create a copycat version of my favorite bars that was healthier and didn’t have chocolate chips. Because to be honest, a pet peeve of mine is that so many protein bars are loaded with chocolate chips when I just want something that’s not sugar-loaded for a snack. (Because I want to eat my chocolate for dessert as a dark chocolate bar!)
So after some tinkering, I found a way to recreate my favorite energy bar at home. You only need six ingredients:
- Old-fashioned rolled oats form the base of these bars. They also contribute fiber and complex carbohydrates.
- Almond flour is one of my secret weapons for adding protein without using powder.
- Roasted peanuts add the bulk of the protein and create a nice nutty flavor (similar to my store-bought bars). I like using roasted peanuts for the best flavor; salted or unsalted peanuts work similarly.
- Medjool dates are nature’s candy and the only sweetener in this recipe. These have the perfect soft, sticky texture that binds everything together: do not use any other type of date! Deglet noor do not work. Make sure your dates are fresh and pliable – if they’re dried out, soak them in warm water for 10 minutes before using.
- Vanilla extract and salt might seem minor, but they’re essential for flavor!
My tips for perfect protein bars
I’ve made these bars countless times, and I’ve learned a few tricks that make all the difference:
- Check your dates before starting. Fresh Medjool dates should be soft and sticky. If yours are dried out, soak in warm water for 10 minutes and drain before using. This ensures they’ll blend smoothly and bind the mixture properly.
- When you’re food processing the dough, the mixture should hold together when squeezed but not be wet or sticky. The water amount in the recipe can vary depending on how moist your dates are. Start with 2 tablespoons and add more gradually if needed.
- Use a small glass or measuring cup to press and roll the mixture in the pan. This creates a smooth, even layer that cuts cleanly into bars.
A note on batch size
This recipe makes 8 square bars in a 9″ loaf pan. If you’d like to double the recipe, you can make a double recipe in a 9 x 9″ square pan.
Storage and make-ahead tips
Store these oatmeal protein bars in an airtight container in the refrigerator for up to 2 weeks. (Of course, they rarely last that long in my house!)
For meal prep, it’s easy to make a double batch. You can also freeze these bars for up to 3 months. I wrap them individually in parchment paper, then store in a freezer bag. They thaw quickly at room temperature, or you can eat them straight from the freezer for a firmer texture.
