Ingredients You’ll Need

  • 1 cup unsalted butter, softened
  • 3/4 cup granulated sugar
  • 3/4 cup brown sugar, packed
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup semi-sweet chocolate chips
  • 1 1/4 cups Reese’s Pieces, plus extra for topping

Kitchen Equipment Needed

  • 9×13-inch baking pan
  • Parchment paper
  • Mixing bowls
  • Stand mixer or hand mixer
  • Measuring cups and spoons
  • Whisk
  • Spatula
  • Cooling rack

Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper and lightly spray with nonstick cooking spray to ensure easy removal.

2. Prepare the Dough

In a large bowl or the bowl of a stand mixer, beat the softened butter, granulated sugar, and brown sugar together until light and fluffy (about 2-3 minutes). Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

3. Combine Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this mixture to the wet ingredients, mixing until just combined.

4. Add Mix-Ins

Gently fold in the chocolate chips and 1 1/4 cups of Reese’s Pieces, reserving a handful for the topping.

5. Assemble and Bake

Spread the cookie dough evenly into the prepared pan. Sprinkle the reserved Reese’s Pieces over the top. Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out mostly clean.

6. Cool and Serve

Allow the bars to cool completely in the pan before lifting them out using the parchment paper. Cut into squares and serve.

Tips & Tricks

  • Use Room Temperature Ingredients – This helps create a smooth dough that blends easily.
  • Don’t Overbake – The bars will continue to set as they cool, so take them out when they are slightly underbaked for the best chewy texture.
  • Make It Extra Gooey – Add an extra 1/2 cup of chocolate chips for an even richer bite.
  • Swap the Mix-Ins – Try using white chocolate chips, peanut butter chips, or even chopped nuts for variety.

Storage Instructions

These cookie bars can be stored in an airtight container at room temperature for up to 5 days. For longer storage, keep them in the refrigerator for up to 2 weeks or freeze them for up to 3 months. To thaw, let them sit at room temperature for 15-20 minutes before enjoying.

Food & Drink Pairings

  • Pair with Milk – The classic choice for cookies and bars!
  • Serve with Coffee – A great afternoon pick-me-up.
  • Top with Ice Cream – Warm up a bar and add a scoop of vanilla or chocolate ice cream for a decadent dessert.

FAQ

Can I make these bars gluten-free?

Absolutely! Try replacing half of the butter with creamy peanut butter for even more peanut flavor.

How do I make these bars chewier?

For extra chewiness, add an extra egg yolk to the dough and slightly underbake them.

Yes! You can double the ingredients and bake in two pans or use a larger baking sheet. Just adjust the baking time accordingly.
