Peanut Butter Protein Bars Ingredients
For the Base
• Oat Flour – Provides structure and chewiness; substitute by blending whole oats for a similar texture.

• Protein Powder – Adds a punch of protein; use vanilla-flavored for a subtly sweet taste.
For Sweetness
• Granulated Sweetener – Sweetens the bars naturally; consider monk fruit or erythritol for a low-calorie option.
For Coating
• Chocolate (for coating) – Enhances the richness; choose dark or milk chocolate based on your preference.
For Liquid
• Almond Milk – Keeps the dough moist; feel free to swap for any milk of choice, including oat or soy.

Step‑by‑Step Instructions for Peanut Butter Protein Bars
Step 1: Mix Dry Ingredients
In a large mixing bowl, combine 1 cup of oat flour, 1 cup of your choice of nut or seed butter, 1 scoop of protein powder, and ¼ cup of your selected granulated sweetener. Using a sturdy spoon or spatula, mix thoroughly for about 1-2 minutes until all dry ingredients are well-blended and there are no clumps.
Step 2: Add Liquid
Gradually pour in ¼ cup of almond milk while continuously stirring the mixture. This helps to create a firm dough—aim for the texture of playdough. If the mixture feels too crumbly, add an additional tablespoon of almond milk at a time until it holds together well, which should take about 2-3 minutes.
Step 3: Shape Bars
Once the mixture is well-combined, scoop tablespoon-sized portions and roll them into balls or flatten them into bars according to your preference. Place each shaped bar or ball onto a parchment-lined tray, making sure they are spaced apart. This process should take around 5 minutes to ensure even sizes for the peanut butter protein bars.
Step 4: Prepare Chocolate Coating
In a microwave-safe bowl or using a double boiler, melt 1 cup of chocolate until smooth. If using a microwave, heat in 30-second intervals, stirring in between to prevent burning. The melted chocolate should have a glossy appearance and a fluid consistency, which typically takes about 1-2 minutes of total heating time.
Step 5: Coat Bars
Using a fork, dip each molded bar into the melted chocolate, ensuring it is well-coated, and shake off any excess. Place the coated bars back onto the lined tray. Continue this process until all the bars are covered in chocolate, making sure they are spread out to avoid sticking together. This step may take about 5-7 minutes.
Step 6: Chill
Refrigerate the coated peanut butter protein bars for 10-15 minutes, or until the chocolate has completely hardened and feels firm to the touch. This cooling will help the chocolate set properly, creating a delightful texture. You can check after 10 minutes to see how it’s firming up.
Step 7: Serve and Enjoy
Once the chocolates have set, remove the bars from the fridge and gently peel them off the parchment paper. These no-bake peanut butter protein bars are now ready to be enjoyed as a nutritious snack or dessert. Store any leftovers in an airtight container in the fridge for up to a week!

Make Ahead Options
These No-Bake Peanut Butter Protein Bars are fantastic for meal prep! You can make the base mixture up to 24 hours in advance, storing it tightly covered in the fridge to maintain its freshness. Simply shape the bars and allow them to chill for 10-15 minutes until the chocolate sets before serving. If you’re looking to enjoy these bars later in the week, you can coat and slice them, then refrigerate them in an airtight container for up to 3 days. To serve, simply pull them out of the fridge and enjoy a delicious, nutritious snack without any extra work! They’ll be just as delightful and satisfying!
