Ingredient Breakdown
- 3 cups old-fashioned rolled oats
- 3/4 cup natural peanut butter
- 1/3 cup honey or maple syrup
- 1/2 cup mini chocolate chips (optional)
- 2 whole eggs
- Optional add-ins : a handful of walnuts, pecans, or almonds for crunch, chia seeds, sunflower seeds, or even some dried fruit
Let’s Get Cooking!
- Preheat the oven to 350°F.
- In a large bowl, combine all the 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.
- Line a 9×9 inch baking dish or pan with parchment paper. This makes it much easier to remove the bars once baked, trust me on this one!
- Transfer the mixture to the prepared dish or pan. Give it a good press! Very firmly press the mixture into the pan in an even layer, the firmer you press, the better the bars will stick together. If you’re using chocolate chips, sprinkle them on top and then press them down into the bars.
- 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.
- Remove from the oven and place the pan on a cooling rack.
- Let the bars cool completely, this is so important, before cutting them into 16 squares with a sharp knife.

And poof! You’ve made your own peanut butter granola bars!
