Whole oats are a healthy, whole-grain source of complex carbohydrates. They’re also a good source of fiber, vitamins, and minerals. In this recipe, you can substitute quick oats for whole oats, but the bars will be less chewy.

Chocolate Whey Protein Powder
Whey protein powder is a high-quality protein source perfect for post-workout recovery or as a healthy snack. It provides all the essential amino acids your body needs to build and repair muscle tissue. This recipe can substitute protein powder, but the bars will be less chocolatey (more on this below).
Peanut butter is a good source of protein and healthy fats. This recipe can substitute nut butter, but the bars will be less peanutty.
Eggs are a binder in this recipe but offer some bonus protein. You can substitute two tablespoons of ground flaxseed or chia seeds soaked in 6 tablespoons of water for the eggs if you’re looking for a vegan option.
Maple syrup is a natural sweetener with a unique flavor. You can substitute honey or agave nectar for the maple syrup, but the bars will be less sweet.
Optional Toppings or Mix-Ins
I mixed chocolate chips with this recipe, but you can add any mix-ins you’d like. Try mixing chopped nuts, seeds, coconut flakes, M&M’s, or dried fruit for more texture. Or, you can drizzle chocolate, peanut butter, or another nut butter overtop.
How To Make These Low Sugar Baked Protein Bars
Preheat the oven to 375 degrees F. Meanwhile, mix the dry ingredients, whole oats, and protein powder in a large bowl.
Whisk together eggs, peanut butter, and maple syrup in a smaller bowl until creamy. Pour the egg mixture into the oats and mix until well combined. Add mix-ins if using.
Press into a 9×13 baking dish and place in the oven. Bake for about 15 minutes.
Let cool, then cut into 12 bars. Enjoy!
Make It Vegan
- Use two tablespoons of ground flaxseed or chia seeds soaked in 6 tablespoons of water for the eggs.
- Be sure to use vegan protein powder and mix-ins
Try a New Flavor
- Swap the chocolate protein powder for vanilla protein powder and play around with different mix-ins. There really is no wrong way to experiment with this recipe.
- Add vanilla extract, cinnamon, or other sweet seasonings to customize this recipe.
How To Store & Meal Prep:
These bars can be stored in an airtight container in the fridge for up to a week.
If you want to meal prep them, make a batch on Sunday and enjoy them throughout the week as a healthy snack or post-workout fuel.
