Ingredients
These chewy homemade nut-free protein bars are the perfect healthy snack. They’re made with simple ingredients like rolled oats, maple syrup, protein powder, and mini chocolate chips. No peanuts and no tree nuts in this recipe!
- 1 ½ cups old-fashioned rolled oats (gluten-free certified if needed)
- ¼ cup oat flour (spooned & leveled (homemade or store-bought))
- ⅓ cup protein powder (I use unflavored whey for best results)
- ½ tsp salt
- ¼ cup melted coconut oil
- ¼ cup maple syrup or honey
- 1 tbsp brown sugar or coconut sugar
- 1 tsp vanilla extract
- 2 – 4 tbsp mini chocolate chips (plus more for melting)
- flaky salt (optional)
How to Make Nut-Free Protein Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a loaf pan (approximately 8½ x 4½ x 2½ inches) with parchment paper.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine:
1. Rolled oats
2. Oat flour
3. Protein powder
4. Salt
Step 3: Prepare Wet Mixture
In a separate small bowl, whisk together:
1. Maple syrup or honey
2. Brown sugar
3. Melted coconut oil
4. Vanilla extract
It may not fully incorporate; that is okay.
Step 4: Combine Mixtures
Add the wet mixture to the dry mixture. Toss until everything is incorporated and there are no dry bits left. It should look and taste kind of like cookie dough.
Step 5: Press into Pan
Press the dough evenly into the parchment-lined loaf pan.
Step 6: Bake
Bake for 10 – 12 minutes until puffed up and lightly golden brown at the edges. They might not look fully done when you take them out, but they will set as they cool.
Step 7: Cool and Add Toppings
Once baked, remove from oven and allow to cool at room temperature. Drizzle with additional melted chocolate and sprinkle flaky salt on top if desired.
Step 8: Enjoy!
Cut into bars and enjoy your delicious nut-free protein bars!

Common Mistakes to Avoid
Making nut-free protein bars can be simple, but there are common pitfalls to watch for. Here are some mistakes to avoid for the best results.
- Using the wrong oats: Not all oats are created equal. Ensure you use old-fashioned rolled oats for the right texture, as instant oats may make your bars too mushy.
- Not measuring ingredients accurately: Precision matters! Use a kitchen scale or measuring cups to ensure your ratios are correct for consistent results.
- Skipping the cooling time: Patience is key! Allowing the bars to cool completely helps them firm up, so they hold together better when cut.
- Overbaking or underbaking: Keep an eye on your bars while they bake. They should be lightly golden and puffed but may not look fully done when you take them out.
- Failing to customize: Don’t hesitate to add your favorite mix-ins! Consider dried fruit, seeds, or different flavors of protein powder for variety.
