No-Bake Peanut Butter Protein Bars Ingredients
For the Base
• Peanut Butter – A deliciously creamy base, providing healthy fats and protein; consider almond butter for a different taste.
• Protein Powder – Essential for boosting the protein content; opt for plant-based versions if you’re crafting vegan-friendly bars.
• Maple Syrup – A natural sweetener that binds ingredients together; honey can be substituted if you’re not strict about vegan options.
For the Topping
• Chocolate Chips – Adds a sweet and delightful crunch to each bite; use dairy-free chips to keep your No-Bake Peanut Butter Protein Bars vegan.
Step‑by‑Step Instructions for No-Bake Peanut Butter Protein Bars (5 Simple Ingredients!)
Step 1: Combine the Base Ingredients
In a large mixing bowl, gather your creamy peanut butter, protein powder, and maple syrup. Use a rubber spatula to mix these ingredients thoroughly for about 2–3 minutes until you achieve a smooth and even consistency. The mixture should be thick yet pliable, perfect for forming your No-Bake Peanut Butter Protein Bars.
Step 2: Incorporate the Chocolate Chips
Gently fold in half of your chocolate chips to the mixture, ensuring they are evenly distributed throughout. This should take about a minute of gentle mixing; be careful not to overwork the mixture. The chocolate will bring a delightful sweetness that complements the nutty flavor of the bars, making them extra tempting!
Step 3: Press into the Pan
Line a square baking pan (8×8 inches works great) with parchment paper. Transfer the peanut butter mixture into the prepared pan, using a spatula to press it down firmly and evenly until it’s smooth and compact. This step is crucial for ensuring your No-Bake Peanut Butter Protein Bars hold their shape once chilled, so make sure the surface is flat.
Step 4: Add the Topping
Sprinkle the remaining chocolate chips over the pressed mixture, distributing them evenly to ensure every bite has that delicious chocolate goodness. If desired, add a pinch of sea salt on top to enhance the flavors, balancing the sweetness of the chocolate. Now, you’re ready to chill!
Step 5: Chill to Set
Place the baking pan in the refrigerator and let it chill for about 1 hour. This process allows the No-Bake Peanut Butter Protein Bars to firm up beautifully. Once the time is up, check the bars—the mixture should feel set and firm to the touch, making them easy to cut into squares or rectangles.
Step 6: Cut and Store
Once set, remove the bars from the pan using the parchment paper as a handle. Place them on a cutting board and slice into your desired size—whether small bites or hearty bars. Store the extra pieces in an airtight container in the fridge for up to a week, or freeze them for longer storage, keeping your healthy snacks ready to go!
