💡 The recipe in a nutshell:
- Vegan (dairy free & no eggs)
- Easy to make
- No bake recipe
- Whipped up in minutes
- Healthy, protein rich snack
- Freezer friendly
- Perfect for meal prep
- Great for most diets, including gluten free
- Oat flour: a gluten-free flour made out of oats and it provides the bars with lots of nutrients including protein and dietary fiber.
- Almond flour: is a gluten-free flour made out of just almonds, and it helps bind the dough together. Almond flour adds protein and healthy fats and gives texture to the bars.
- Protein Powder: Using a good quality protein powder that tastes good is key. We recommend Naked Nutrition's Chocolate PB Protein Powder, as it is entirely plant-based, is of good quality, and pairs the flavor of the bars perfectly
- Smooth Peanut Butter: helps bars to stick together, provides protein and healthy fats, and gives them that delicious peanut butter flavor that pairs so well with chocolate.
- Cocoa Powder: To add chocolate flavor. Use unsweetened, good-quality cocoa powder for best results.
- Agave Syrup: To skip refined sugar, these protein bars are sweetened with agave syrup instead. You can substitute it with another liquid sweetener such as maple or rice syrup. In addition, the agave helps the protein bars to hold together.
- Oat milk: Use it to give the batter moisture and creaminess.
- Dark Chocolate Chips: Used as the chocolate layer on top of the bars. This will give your protein bars that treat-like feel! Use sugar-free chocolate, if wished.
- Coconut Oil (optional): Adding coconut oil is optional, used in the chocolate topping. It helps the chocolate to create a runnier consistency. Moreover, it makes it easy to spread the chocolate. Additionally, it will soften the chocolate layer, so it does not break when cutting the slices.
- Sea salt to sprinkle (optional): Adding salt to sweets helps enhance the flavor profile and compliments the dark chocolate well.

👩🏽🍳 Tips to make the best chocolate pb protein bars
To ensure these are the best chocolate protein bars ever, we have some tips for you:
- Sprinkle the tops of each protein bar with sea salt, for an extra dose of flavor. The salt helps enhance all the amazing flavors, even the sweetness!
- To make thicker bars, I recommend using a smaller pan such as an 8 by 8-inch, or loaf pan instead of a rectangular 9 by 13-inch pan.
- Use quality ingredients. This is a rather obvious tip, but if you have the privilege to purchase fresh, organic, and high-quality products, do so!
💭 Common questions
- My batter is too thick, what can I do? If the batter for the protein bars is too thick and/or crumbly, add some water or plant milk to it, to thin it out. Moreover if you want the batter to be thick, and doughy.
Can I skip or swap the peanut butter? If you have a peanut or nut allergy, swap the peanut butter with a different nut or seed butter (such as tahini). Do not skip this ingredient, as it is an essential for the bars to stick together. Keep in mind that it will alter the flavor.
- What protein powder should I use? Using a good quality protein powder that tastes good is key. The protein powder flavor can be evident, so make sure you enjoy the flavor. We recommend Naked Nutrition's Chocolate Peanut Butter Protein Powder, as has great quality and pairs the flavor of the bars perfectly.
- Can I skip the protein powder? Skipping the protein powder is possible. However, skipping it may result in a different texture of the bars. Adding protein powder gives these protein bars the extra boost, helping you reach your goals and to fill full quicker!
