👨‍🍳 How to Make Protein Granola Bars

Step 1: Mix the Wet Ingredients

In a medium saucepan over low heat, combine peanut butter, honey, and vanilla extract. Stir gently until smooth and melted, about 2–3 minutes.

Step 2: Combine Dry Ingredients

In a large mixing bowl, add rolled oats, protein powder, salt, and any desired mix-ins. Stir to combine.

Step 3: Combine and Mix

Pour the warm peanut butter-honey mixture over the dry ingredients. Stir until fully combined. The mixture should be thick and sticky.

Step 4: Press Into Pan

Line an 8×8-inch or 9×9-inch square pan with parchment paper. Transfer the mixture to the pan and press it down firmly with a spatula or your hands to form an even layer.

Step 5: Chill and Set

Refrigerate for at least 1 hour, or until firm. Once set, lift out of the pan and slice into bars.

📝 Notes

• Storage: Store bars in an airtight container in the fridge for up to 1 week, or freeze for up to 2 months.

• Make it Vegan: Use maple syrup and plant-based protein powder.

• Nut-Free Option: Substitute sunflower seed butter for peanut or almond butter.

• Texture Tip: For chewier bars, add a splash of milk or plant-based milk if the mixture feels too dry.

❓FAQs

Can I use steel-cut oats?
No, rolled oats or quick oats are best. Steel-cut oats are too tough for no-bake bars.

Do I have to use protein powder?
No, but it enhances the protein content. You can skip it and increase oats slightly.

Can I bake these bars?
These are no-bake bars, but you can bake them at 325°F (160°C) for 10–12 minutes if you prefer a firmer texture.

What’s the best protein powder to use?
Use a protein powder you like the taste of—vanilla or chocolate flavors work well. Both whey and plant-based powders are suitable.
