Course: Dessert
Servings: 9 bars



  • 1/2 cup creamy natural peanut butter
  • 1/2 cup crunchy natural peanut butter
  • 1/2 cup coconut sugar
  • 1/3 cup pure maple syrup
  • 2 eggs
  • 1 tsp pure vanilla extract


  • 1 1/2 cups old fashioned oats
  • 1 tsp baking soda
  • 1/4 tsp sea salt
  • 1/3 cup chocolate chips dairy free if needed


  • Preheat the oven to 350F and line a 8x8 baking pan with parchment paper.
  • Next, in a large mixing bowl, either with a stand mixer or using an electric hand mixer, whisk together the two peanut butters, coconut sugar, maple syrup, and vanilla until smooth. Crack in one egg at a time and whisk until combined.
  • Stir in the oats, baking soda and sea salt until just combined, making sure to not over mix.
  • Fold in the chocolate chips and transfer the batter to your baking pan, making sure to press the mixture down evenly with the back of a rubber spatula.
  • Bake in the oven for 18-20 minutes or until the edges are rounded and the top is slightly firm to the touch.
  • Transfer to a cooling rack and allow it to fully cool to firm up a bit before slicing, as this will ensure they are extra gooey and soft inside.
