Once I realized how easy it is to make homemade granola bars, I stopped buying the packaged kind altogether. These peanut butter granola bars are soft-baked, naturally gluten-free, and made with simple ingredients for a delicious, wholesome snack.

Prep: 5 mins Cook: 14 mins Total: 19 mins
Servings: 16 squares 1x
Scale

Ingredients

  • 3 cups old-fashioned rolled oats (use verified gluten-free, if needed)
  • ¾ cup natural peanut butter*
  • cup honey or maple syrup (both work well and taste great but honey helps hold the bars together better)
  • ½ cup mini chocolate chips (optional)
  • 2 whole eggs (use flax egg for vegan-friendly**)
  • Optional add-ins: pinch of salt (omit if peanut butter is salted), walnuts, pecans, almonds, chia, sunflower, or pumpkin seeds, or dried fruit

Instructions

  1. Preheat oven to 350℉.
  2. In a large bowl, combine all ingredients and mix well. If your peanut butter is solid at room temperature, heat it for 10-15 seconds to make it a more drizzly consistency before adding it to the mix.
  3. Line a 9×9-inch baking dish or pan with parchment paper. This makes it much easier to remove the bars from your dish once baked.
  4. Transfer the mixture from the mixing bowl to the prepared dish or pan. 
  5. Very firmly press the mixture into the pan in an even layer. The firmer you press, the better the bars will stick together. 
  6. If you’re using chocolate chips, sprinkle them on top, then press them down into the bars.
  7. Bake for 15-17 minutes or until the center is baked through and the edges are just starting to brown. Start checking at 14 minutes, as all ovens are different.
  8. Remove from the oven and place the pan on a cooling rack.
  9. Let the bars cool completely before cutting them into 16 squares with a sharp knife.

Notes

*Use certified gluten-free oats to make these gluten-free and celiac-friendly. 

**These chewy granola bars are easy to adapt if I need a nut-free option. I’ll swap the peanut butter for sunflower seed butter, tahini, or pumpkin seed butter for a similar texture and binding effect.

***To make these egg-free/vegan, substitute 2 flax eggs in place of the eggs. To make them, mix 2 tablespoons ground flaxseed with 5 tablespoons water and let the mixture sit for 5-10 minutes before adding it in.

For the perfect chewy texture, avoid overbaking these, since even a few extra minutes in the oven can make them crispy and crumbly. I also make sure to use enough moisture-rich ingredients like peanut butter (with a drizzly consistency) and maple syrup or honey. 

I prefer cutting the bars into squares, and that’s what the nutrition facts below are based on. However, I can also divide the pan into 12-14 longer bars, if preferred.

Use a sharp, non-serrated knife to slice the bars, and avoid dragging it through. Instead, press straight down for clean cuts and to help keep the bars intact.
