Ingredients

low sugar baked protein bars ingredients

Whole Oats

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

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

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

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

Try a New Flavor
