Peanut Butter Cookie Bars

I love peanut butter, and my son adores chocolate. I tried for a long time to find the perfect recipe to make both of us happy. This recipe is perfection! The cookie bars are soft, chewy and thick with a chocolate layer on top covered with a sprinkling of M & M's. You will just have to check out these peanut butter cookie bars for yourself!

Ingredients

Servings
  • 1 cup salted butter melted and cooled slightly *see note (226 g)
  • 2 large eggs
  • 2 cups brown sugar packed (440g)
  • 1 tablespoon vanilla extract
  • 1 cup creamy peanut butter not all natural (240g)
  • 2 ½ cups all purpose flour 350 g
  • ½ teaspoon baking powder
  • 1 ¼ cups mini peanut butter M&M’s

Chocolate Topping

  • 1 ½ cups chocolate chips
  • 1 tablespoon butter

Decoration

  • ½ cup mini peanut butter M&M’s

Instructions

  1. Preheat an oven to 350 Fahrenheit and spray a 9x13 baking dish with non-stick spray. *see note
  2. Add the flour, baking powder, and mini peanut butter M&M’s together in a mixing bowl and whisk together.
  3. In a large mixing bowl whisk the slightly cooled butter and eggs together till smooth.
  4. Add the brown sugar, and vanilla and whisk again till smooth.
  5. Add the peanut butter and whisk till smooth.
  6. Add the flour mixture and M&Ms and mix with a spoon till just combined.
  7. Turn the batter out into the prepared baking dish, smoothing the top slightly so it’s even.
  8. Bake for 30-35 minutes or until the top is set and golden brown.
  9. Remove from oven and let cool in baking dish till nearly completely cool before making the topping.
  10. In the microwave in 20 second increments at 50% power, melt the chocolate chips and butter together.
  11. Once melted, spread the chocolate on top of the bars and sprinkle with the peanut butter M&M’s

Notes

  • If you use unsalted butter in the batter, add ¼ teaspoon salt to your flour mixture.
  • If you use a glass baking dish your cook time will likely be a few minutes less than if you use a metal dish.
  • I prefer using a baking dish that has more defined corners than rounded edges because it makes more bars squared.
  • If you can’t find mini peanut butter M&M’s you can use regular M&M’s. I found mini peanut butter M&M’s at my local Walmart.
  • If you don’t want to make as many bars, you can half this recipe and bake in a 8x8 inch baking dish.
