Ingredients
- 2 cups old-fashioned rolled oats
- 1 1/4 cups all-purpose flour
- 1 tsp baking soda
- 1/2 tsp salt
- 1/2 cup unsalted butter, softened
- 3/4 cup creamy peanut butter
- 1 cup brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 2 tsp vanilla extract
- 1 cup semisweet chocolate chips
- 1 cup candy-coated chocolate pieces (like M&M’s), divided
Instructions
Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper.
- In a medium bowl, whisk together oats, flour, baking soda, and salt.
- In a large bowl, cream together butter, peanut butter, brown sugar, and granulated sugar until smooth and fluffy.
- Beat in eggs and vanilla until well combined.
- Gradually add the dry ingredients to the wet ingredients and mix until just combined.
- Fold in chocolate chips and most of the candy-coated chocolates, reserving some for topping.
- Spread the dough evenly in the prepared pan. Press the remaining candy pieces on top.
- Bake for 25–30 minutes, or until golden brown around the edges and just set in the center.
- Allow to cool completely in the pan before slicing into bars.
Notes
- Don’t overbake—bars continue to set as they cool.
- Use parchment paper for easy removal and clean slicing.
- Customize with different candy colors for holidays or events.
- Store in an airtight container at room temperature for up to 5 days or freeze for longer storage.
