Method
 

Instructions
  1. Prepare Your Pan and Preheat the Oven: Line a 9x9 inch pan with parchment paper. Preheat your oven to 350°F (180°C).
  2. Cream the Butters and Sugars: Cream together ½ cup salted butter and ½ cup peanut butter until smooth. Then add ¾ cup brown sugar and ½ cup granulated sugar, mixing until fully integrated, about 2-3 minutes.
  3. Add the Eggs and Vanilla: Crack in 2 large eggs and pour in 1 teaspoon of vanilla extract. Beat until well incorporated and slightly fluffy.
  4. Combine Dry Ingredients: In a separate bowl, whisk together 1 cup all-purpose flour, 2 cups rolled oats, ½ teaspoon baking soda, ½ teaspoon baking powder, and a pinch of salt. Gradually add this to the wet ingredients, stirring until just combined.
  5. Fold in the Chocolaty Goodness: Fold in 1 cup semi-sweet chocolate chips and ½ cup M&M’s, ensuring even distribution.
  6. Spread the Dough in the Pan: Transfer the dough to your prepared pan and press it evenly into all corners.
  7. Bake to Perfection: Bake for 25 to 30 minutes until the top is golden brown. Check for doneness with a toothpick.
  8. Cool and Slice: Let cool completely on a wire rack for about 20-30 minutes before cutting into squares.
