Ingredients

Scale

Base Ingredients

  • 1 cup butter (room temperature)
  • 3/4 cup light brown sugar
  • 3/4 cup granulated sugar
  • 1 cup creamy peanut butter
  • 2 whole large eggs
  • 1 tsp vanilla extract
  • 2 cups all-purpose flour
  • 2 cups old fashioned oats
  • 1 tsp baking powder
  • 1/2 tsp salt

Topping Ingredients

  • 12 oz milk chocolate chips
  • 1 cup creamy peanut butter

Instructions

  1. Preheat Oven: Preheat your oven to 350º F to prepare for baking the bars.
  2. Cream Butter and Sugars: Using an electric mixer, beat together the softened butter, light brown sugar, granulated sugar, and 1 cup creamy peanut butter until the mixture is light and fluffy, ensuring good incorporation of all ingredients.
  3. Add Eggs and Vanilla: Mix in the two whole eggs and vanilla extract until fully combined for a smooth batter.
  4. Combine Dry Ingredients: Add the oats, all-purpose flour, baking powder, and salt to the wet mixture. Stir until just combined to form the oat-based dough.
  5. Press into Pan and Bake: Press the dough evenly into a 13×9 inch baking pan. Bake in the preheated oven for 20-25 minutes, until the edges turn golden and the center is set but still chewy.
  6. Cool Slightly: Remove the pan from the oven and let it cool for a few minutes to make adding the topping easier.
  7. Prepare Topping: In a microwave-safe bowl, combine the milk chocolate chips and 1 cup creamy peanut butter. Microwave for 60 seconds, then stir until the chocolate is fully melted and smooth.
  8. Spread Topping: Pour the melted chocolate and peanut butter mixture evenly over the warm bars and spread into a smooth layer.
  9. Set and Serve: Allow the chocolate topping to set at room temperature before slicing into bars and serving.

Notes

  • Use old fashioned oats for the best texture; quick oats may result in a different consistency.
  • Ensure the butter is softened to room temperature for easier mixing and better texture.
  • The bars can be stored in an airtight container at room temperature for up to 3 days or refrigerated for up to a week.
  • For a dairy-free version, substitute butter with a vegan butter alternative and use dairy-free chocolate chips.
  • Optional: sprinkle a pinch of sea salt on top of the chocolate while it’s still warm for a sweet-salty flavor twist.
