Ingredients
  

Wet Ingredients

  • 1 cup creamy peanut butter
  • 1 cup brown sugar packed
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract

Dry Ingredients

  • 1 1/2 cups gluten-free rolled oats
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt

Mix-ins

  • 1 cup chocolate chips (dark or semi-sweet)
  • 1/2 cup M&M's optional for color and fun

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking dish or line it with parchment paper.
  • In a large bowl, combine the creamy peanut butter, brown sugar, granulated sugar, eggs, and vanilla extract. Mix well until creamy.
  • In another bowl, whisk together the gluten-free rolled oats, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring until just combined.
  • Gently fold in the chocolate chips and M&M's.

Baking

  • Pour the batter into the prepared baking dish, smoothing it evenly.
  • Bake for about 20-25 minutes, or until the edges are golden and a toothpick inserted into the center comes out clean.

Cooling and Serving

  • Allow the bars to cool in the pan before transferring them to a cutting board.
  • Cut them into squares and enjoy!

Notes

For best results, measure ingredients accurately and don't overmix. Customize your bars with different mix-ins as desired. Store in an airtight container at room temperature for up to a week or freeze for up to three months.
