Step-by-Step Instructions
Follow these detailed steps to create perfect Reese’s Pieces Cookie Bars every time:
1. Prep Work: Preheat your oven to 350°F (175°C). Line your 9×13 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal. Lightly spray with cooking spray.
2. Mix Wet Ingredients: In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 3-4 minutes. Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract and peanut butter until smooth.
3. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt.
4. Form Dough: Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix. Fold in 1 cup of the Reese’s Pieces and all of the chocolate chips by hand using a rubber spatula.
5. Transfer to Pan: Press the cookie dough evenly into the prepared baking pan. Sprinkle the remaining 1/2 cup of Reese’s Pieces Cookies pieces on top, gently pressing them into the surface.
6. Bake: Place in the preheated oven and bake for 25-30 minutes, until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
7. Cool: Allow the cookie bars to cool completely in the pan on a wire rack before cutting into squares. For clean cuts, refrigerate for about 30 minutes before slicing.
Troubleshooting & Pro Tips
– Too Crumbly? You might have overbaked them. Next time, check 5 minutes before the recommended baking time.
– Too Gooey? If the center isn’t set enough, allow additional baking time in 2-minute increments.
– For Thicker Bars: Use a 9×9 inch pan and increase baking time by about 5-7 minutes.
– Perfect Texture: For that bakery-style chewiness, slightly underbake the bars. They’ll continue to set as they cool.
– Even Better Flavor: Try browning the butter before using it for a deeper, nutty flavor profile.
– Presentation Tip: For a professional finish, let the bars cool completely before cutting with a sharp knife. Clean the knife between cuts.
Storage & Make-Ahead Tips
– Room Temperature: Store in an airtight container for up to 3 days.
– Refrigerator: Extend freshness to 7 days by refrigerating in an airtight container.
– Freezer: These bars freeze exceptionally well for up to 3 months. Wrap individual pieces in plastic wrap, then store in a freezer bag.
– Make-Ahead Option: The cookie dough can be prepared and refrigerated for up to 3 days before baking, or frozen for up to 1 month.
– Serving Tip: For the ultimate treat, warm a bar in the microwave for 10-15 seconds and top with a scoop of vanilla ice cream.

FAQ
Can I make these gluten-free?
Yes! Simply substitute the all-purpose flour with your favorite 1:1 gluten-free flour blend. The texture may be slightly different, but still delicious.
How do I know when the bars are done baking?
The edges should be golden brown, and a toothpick inserted in the center should come out with a few moist crumbs but not wet batter. Remember, they will continue to set as they cool.
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add extra texture to your bars. Just make sure it’s the conventional kind, not natural peanut butter that separates.
What if I don’t have Reese’s Pieces?
You can substitute with Homemade Reese’s Eggs chopped into pieces, or use M&Ms, peanut butter chips, or additional chocolate chips.
Can I double this recipe?
Yes! Double all ingredients and bake in two 9×13 inch pans, or use a half sheet pan (approximately 18×13 inches) and increase the baking time slightly.
