🥜What you will need

- Oat flour - Easily make your own at home by blending oats in a high-speed blender or food processor. Make it gluten-free by using a certified gluten-free oat flour.
- Protein powder - Both whey and plant-based can be used. I am using Orgain's vanilla protein powder. You can also use peanut butter or chocolate-flavored protein powder.
- Maple syrup - I am opting for zero-sugar maple syrup to keep this recipe low sugar. Feel free to use other liquid sweeteners like agave or honey.
- Peanut butter - Use natural peanut butter with just peanuts and salt that are runny. Can be substituted with other nut butters like almond or cashew butter. Use sunflower seed butter or tahini to make this recipe nut-free.
- Chocolate chips - I am using Enjoy Life's dark chocolate morsels, but feel free to use your preferred chocolate chips/ chocolate bar.
- Coconut oil - Creates a smoother chocolate layer. Can be omitted or substituted with butter or vegan butter.
- Flaked sea salt - Optional topping for chocolate peanut butter protein bars. Enhances the flavor of these protein bars.
🔪How to make chocolate peanut butter protein bars

Step 1: Whisk together peanut butter, maple syrup, plant milk, and vanilla extract.

Step 2: Add oat flour, protein powder, and salt. Mix until a homogenous mixture forms.

Step 3: Press the dough mixture firmly into a lined 9x9 baking pan.

Step 4: : Add chocolate chips and coconut oil to a small bowl. Microwave at 30-second intervals until the chocolate has completely melted.

Step 5: Pour melted chocolate over the dough, spreading it out evenly using the back of a spoon.

Step 6: Allow peanut butter chocolate protein bars to firm up in the freezer for at least 30 minutes before slicing and serving.
✔️Helpful tips
- Adjust the consistency of dough mixture - Dough should hold together but not overly sticky. If it is too crumbly, add more milk, a tablespoon at a time. The reverse is also true; so, do add more protein powder or flour if the mixture is overly sticky!
- Allow parchment paper to overhang - To easily remove protein bars from the pan. For more details, check out this post on how to create an overhang.
- Keep bars refrigerated - As this is a no-bake recipe, do keep bars in the fridge until ready to serve. They will turn soft after a while.
- Tips to slice protein bars cleanly - Run a sharp knife under hot water and wipe it dry beforehand to slice through protein bars cleanly. You will also want to wipe your knife clean between each cut.
❄️Storing suggestions
Fridge - Store peanut butter protein bars in an airtight container. They can be refrigerated up to a week.
Freezer - Protein bars can be frozen for 3 months. Store them in Ziplock bags before freezing. Allow them to thaw and soften for a few minutes outside before enjoying.
