How to Make Chocolate Peanut Butter Protein Bars
- Mix the wet ingredients – In a mixing bowl, stir together peanut butter, honey (or maple syrup), and milk until smooth. If your peanut butter is too thick, microwave it for a few seconds to loosen it up.
- Add the dry ingredients – Fold in protein powder, cocoa powder, oats, and sea salt, mixing until a thick dough forms. It should be slightly sticky but firm enough to hold together.
- Press into a pan – Line a square pan with parchment paper and firmly press the mixture into an even layer. Use a spatula or the back of a spoon to smooth it out.
- Melt and drizzle the chocolate – Melt the dark chocolate chips and drizzle (or spread) over the top. For extra crunch, sprinkle some chopped nuts or sea salt on top!
- Chill and slice – Place the pan in the fridge for at least 30 minutes to set. Once firm, slice into bars and enjoy!
Pro Tips for Making chocolate peanut butter protein bars
Use natural, runny peanut butter – If your peanut butter is too thick or dry, it’ll be hard to mix. A creamy, drippy peanut butter works best!
- Adjust the sweetness – If you like it sweeter, add a little extra honey or maple syrup. Want it less sweet? Reduce it slightly.
- Customize with add-ins – Mix in chia seeds, flaxseeds, or crushed nuts for extra texture and nutrition.
- For a firmer texture – Keep the bars in the fridge for a chewier bite, or freeze them for a firmer, candy bar-like texture.
- Make it vegan – Use a plant-based protein powder and dairy-free chocolate.

Make Ahead and Storage
Storing Leftovers

- For softer bars, leave them at room temperature for 5-10 minutes before eating.
Freezing
- Wrap individual bars in parchment paper and store in a freezer-safe bag for up to 3 months.
- Let them thaw for a few minutes before eating, or enjoy them straight from the freezer for a firmer texture.

FAQs about chocolate peanut butter protein bars
Can I use a different nut butter?
Yes! Almond butter, cashew butter, or even sunflower seed butter work great. Just make sure it’s smooth and creamy.
What’s the best protein powder for this recipe?
Any chocolate-flavored protein powder works! Whey protein, plant-based protein, or collagen powder are all great options. If using unflavored protein powder, add an extra tablespoon of cocoa powder for a stronger chocolate taste.
Can I make these bars without protein powder?
Yes! If you want to skip the protein powder, just increase the oats by about ¼ cup or use almond flour instead. This will help maintain the right texture.
Why are my bars too crumbly?
If your bars aren’t holding together well, they might be too dry. Add an extra splash of milk or more peanut butter until the mixture sticks together easily. It should feel sticky but not overly wet.
