Ingredients

  • 2 eggs
  • 1 cup peanut butter
  • cup pure maple syrup
  • 1 tsp vanilla extract optional
  • 1 ½ cups rolled oats
  • ¼ tsp baking soda
  • 1/2 tsp ground cinnamon optional
  • 1/2 tsp sea salt
  • 1 cup chocolate chips optional

Instructions

  • Preheat the oven to 350 degrees Fahrenheit and line an 8-inch square pan with parchment paper.
  • Combine the eggs, peanut butter, and pure maple syrup (and vanilla extract if adding) in a large bowl and mix until everything is well combined. Note: if your peanut butter is cold or seems firm, microwave it for 20 to 30 seconds to help with the mixing process.
  • Add the rolled oats, baking soda, ground cinnamon and sea salt (dry ingredients) to the mixing bowl and mix until everything is combined and a thick dough forms.
  • Stir in the chocolate chips (if adding).
  • Transfer the peanut butter oatmeal cookie dough to the prepared baking pan and spread it into an even layer. If you’d like, sprinkle the top with extra chocolate chips and/or flaky sea salt.
  • Bake on the center rack of the preheated oven for 20 to 25 minutes or until the bars have set up and the edges are slightly golden brown.
  • Allow the peanut butter chocolate chip bars to cool for at least 15 minutes before slicing and serving.
