    Since learning how to make protein bars at home, there is no going back to the store-bought ones! Like my oatmeal protein bars, they taste way better and are much cheaper than the ones you get from the groceries.

    💚Why you will love this recipe 

    • A good source of protein - a serving contains a whopping 14g of protein!
    • Chewy, sweet, and incredibly decadent 
    • An easy no-bake recipe that only calls for simple ingredients 
    • Naturally vegan and gluten-free 

    🥜What you will need 

    Ingredients needed like protein powder, oat flour, peanut butter, maple syrup, milk, and other ingredients.

    📃Ingredients notes and substitutions 

    • Oat flour - If you do not have any on hand, make your own by blending some oats in a high-speed blender or food processor.  If you are sensitive to gluten, opt for certified gluten-free oat flour. 
    • Protein powder - I highly recommend using unsweetened and unflavored plant-based protein powder like pea, soy, or rice. Casein or whey-based protein powder will NOT work in this recipe. 
    • Maple syrup - Can be substituted with other liquid sweeteners like agave syrup or honey. You can also use sugar-free syrup, like this Lakanto Sugar-free Syrup, to keep this recipe sugar-free. 
    • Peanut butter - You can use other kinds of nut butter in place. However, you must choose natural nut butter that only contains nuts and salt. 
    • Chocolate chips - To keep this recipe vegan and dairy-free, choose vegan chocolate chips like this Enjoy Life dark chocolate morsels. You can also use your favorite chocolate bar in place. 
    • Coconut oil - Helps chocolate to melt more smoothly. You can substitute it with vegetable oil or canola oil. 

    🔪How to make 

    Start by lining a 9x9 baking pan or other similar-sized pans with parchment paper. 

    Whisk together peanut butter, maple syrup, plant milk, and vanilla extract. Then, add the rest of the ingredients for the dough layer and mix until a dough forms. (You might need to use your hands as the dough is quite dry)

    Gently press the dough into the lined pan. 

    Combine chocolate chips and coconut oil in a microwave-safe bowl, and microwave in 30-seconds intervals until the chocolate is completely melted. 

    Pour melted chocolate over the dough layer. Spread the chocolate into an even layer using the back of a spoon.

    Let chocolate peanut butter protein bars firm up in the fridge for at least 30 minutes before slicing and serving.

    ✔️Helpful tips 

    • If the dough of your protein bars appears dry and crumbly, add more milk, a tablespoon at a time. 
    • Allow your parchment paper to overhang (as shown in the process pictures above) for easy removal. 
    • Allow your protein bars to firm up in the freezer for at least 30 minutes before slicing. If not, you might ruin them and end up with a sticky mess! 
    • To cleanly slice your protein bars: 
      • Run a sharp knife under hot water. 
      • Wipe it dry. 
      • Use it to slice the bars immediately, wiping the knife clean with a kitchen towel between each cut. 

    ❄️Storing suggestions 

    Fridge - These chocolate peanut butter protein bars will last in the refrigerator for a week. Store them in an airtight container before keeping them. 

    Freezer - Protein bars can be frozen for up to 3 months in a freezer bag or storage container. I recommend placing a piece of parchment paper between each layer to prevent them from sticking together. 

    When ready to enjoy, let them thaw for a few minutes at room temperature to allow them to soften.
