• Vanilla Extract – Enhances the flavor profile; use pure vanilla for the most delightful taste.
• Salt – Balances the sweetness and is essential for flavor enhancement.

Step‑by‑Step Instructions for Peanut Butter Protein Bars
Step 1: Prepare the Pan
Begin by preparing an 8×8 or 9×9 inch pan. Lightly spray it with cooking oil or line it with parchment paper, making sure to leave some overhang for easy removal later. This step is crucial for preventing the peanut butter protein bars from sticking, ensuring they come out perfectly shaped after chilling.
Step 2: Melt the Mixture
In a microwave-safe bowl, combine 1 cup of creamy peanut butter, 1/3 cup of honey, and 1/4 cup of coconut oil. Microwave these ingredients for 30-45 seconds until they’re soft and warm. Stir the mixture until smooth and well combined, allowing the warm peanut butter to enhance the flavors—this sets the foundation for your delicious Peanut Butter Protein Bars.
Step 3: Add Flavorful Ingredients
Once the mixture is smooth, stir in 1 teaspoon of vanilla extract, 1/4 teaspoon of salt, and 1/2 teaspoon of cinnamon. Next, add 1/4 cup of flax meal and 1 scoop of protein powder. Mix everything until fully combined, ensuring an even distribution of flavors. This step makes the bars dense and nutrient-packed, perfect for an energy boost.
Step 4: Incorporate Oats and Coconut
Add 1 cup of old-fashioned oats and 1/2 cup of shredded coconut to the mixture. Stir thoroughly until everything is well coated and the oats are evenly dispersed. The texture should be slightly sticky—this is a good sign that your Peanut Butter Protein Bars will hold together nicely after chilling.
Step 5: Fold in Chocolate Chips
If you love a hint of sweetness, fold in 1/2 cup of mini chocolate chips. Ensure the mixture has cooled down enough to prevent melting the chocolate. This step adds delightful bursts of chocolate throughout the bars, creating a balance between healthy and indulgent flavors that everyone will love.
Step 6: Press and Smooth
Transfer the mixture into the prepared pan. Using a spatula or your hands, press the mixture firmly and evenly into the corners, smoothing out the top for a clean finish. This compacting helps the Peanut Butter Protein Bars to hold their shape as they set—an essential step for achieving that perfect chewy texture.
Step 7: Chill to Set
Place the pan in the refrigerator or freezer for about 10-15 minutes. This chilling period is vital for the mixture to firm up, creating the ideal consistency for your homemade snacks. Keep an eye on them; once they’re slightly set and firm to the touch, they’re ready for the next step.
Step 8: Cut and Store
After chilling, remove the bars from the pan using the parchment overhang. Cut them into squares or rectangles, according to your preference. Store your delicious Peanut Butter Protein Bars in an airtight container in the refrigerator for up to one month, or freeze them for longer storage. They are now ready to be enjoyed anytime!

What’s the best way to store the Peanut Butter Protein Bars?
Very! Store these bars in an airtight container in the refrigerator for up to one month. If you’re looking for longer storage, feel free to freeze them for up to three months. Just make sure to use parchment paper in between layers to prevent sticking! When ready to enjoy, simply thaw overnight in the fridge.

What should I do if my Peanut Butter Protein Bars are too crumbly?
Rest assured, it happens to the best of us! If you find the bars too crumbly, next time ensure the peanut butter mixture is slightly warm when mixing in the dry ingredients; this helps bind everything together.

Can these bars accommodate dietary allergies?
Absolutely! They’re quite customizable! Substitute the peanut butter with sunflower seed butter for a nut-free option, and choose gluten-free oats to make them suitable for those avoiding gluten. If you or someone you’re serving has a honey allergy, maple syrup is a great alternative sweetener. Always check all ingredient labels for any specific allergies!
What alternative ingredients can I use to switch up the taste?
Very much! You can easily swap the peanut butter for almond butter or cashew butter for different flavors—just keep proportions similar.
