Ingredients Equipment Method Notes

Ingredients
  

  • 1 cup creamy peanut butter
  • 1 cup brown sugar
  • 1/2 cup melted butter
  • 2 eggs
  • 1 teaspoon vanilla extract
  • 2 1/2 cups rolled oats
  • 1 teaspoon baking soda
  • 1 cup chocolate chips

Equipment

  • Mixing bowls
  • Spatula
  • 9x13 inch baking pan
  • Parchment paper
  • Cooling rack

Method
 

  1. Preheat your oven to 175°C (350°F). Line a 9x13 inch baking pan with parchment paper for easy removal.
  2. In a large mixing bowl, combine the peanut butter and brown sugar. Use a spatula to stir until the mixture is smooth and creamy, with a slightly sticky texture.
  3. Add the melted butter to the bowl and stir until well incorporated, creating a rich, slightly glossy batter.
  4. Crack in the eggs and add vanilla extract, then whisk everything together until the mixture is smooth and cohesive.
  5. Pour in the rolled oats, baking soda, and a pinch of salt. Use the spatula to fold the oats into the wet ingredients, stopping when the mixture is thick and slightly sticky.
  6. Gently fold in the chocolate chips, distributing them evenly throughout the batter for bursts of melty chocolate in every bite.
  7. Spread the batter evenly into the prepared baking pan, pressing it down gently with the spatula to ensure a flat, compact layer.
  8. Bake in the preheated oven for 20-25 minutes, until the edges turn golden brown and the center looks slightly set but still chewy.
  9. Remove the pan from the oven and let the bars cool in the pan for at least 15 minutes to allow them to set and firm up.
  10. Transfer the cooled bars to a wire rack, then cut into squares with a sharp knife, revealing the chewy, chocolate-studded texture inside.
  11. Enjoy these rich, gooey bars as a satisfying snack or dessert—perfect for sharing or savoring on your own!

Notes

For extra chewiness, refrigerate the bars for an hour before slicing. You can also add nuts or dried fruit for variation.
