2 Eggs (whole): Acts as a binder to hold the ingredients together, providing structure and richness to the bars.
2 Egg Yolks: Adds extra richness and make the cookie bars even more tender and chewy.
3 Tsp Vanilla Extract: Enhances the overall flavor with a sweet, aromatic vanilla taste.
4 Cups Flour: The base of the cookie dough, provides structure and substance.
1 Tsp Baking Soda: A leavening agent that helps the cookie bars rise and become light and chewy.
½ Tsp Salt: Balances the sweetness and enhances the flavors of the other ingredients.
1½ Cups Semisweet Chocolate Chips: Adds rich, chocolatey goodness throughout the cookie bars.
1 Cup Reese’s Peanut Butter Chips: Infuses a creamy peanut butter flavor into the cookie bars for a delicious contrast with the chocolate.
2 Cups Reese’s Peanut Butter Candies (topping): Colorful Reese’s Pieces candies for a fun, crunchy topping with extra peanut butter flavor.

HOW TO PREPARE REESE’S PIECES COOKIE BARS?

Time needed: 1 hour

Preheat Oven:

Preheat your oven to 325°F (175°C) and grease a large 11 x 14 baking pan or line it with parchment paper for easy removal.
Mix Wet Ingredients:

In a large mixing bowl or KitchenAid Mixer, combine the melted, slightly cooled butter with the brown sugar and white sugar. Stir together until well-mixed and smooth.

Add the 2 whole eggs, 2 egg yolks, and vanilla extract to the sugar mixture. Stir until fully combined and the batter becomes creamy.
Combine Dry Ingredients:

In a separate bowl, whisk together the flour, baking soda, and salt.
Incorporate Dry into Wet:

Gradually add the dry ingredients into the wet mixture, stirring until a thick cookie dough forms.
Mix in Chocolate & Peanut Butter Chips:

Fold in the semisweet chocolate chips and Reese’s peanut butter chips evenly throughout the dough.
Spread the Dough:

Spread the dough evenly into the prepared 11 x 14 baking pan, making sure it’s smooth and level.
Top with Reese’s Pieces:

Sprinkle the Reese’s Pieces candies generously over the top, pressing them lightly into the dough.
Bake:

Bake in the preheated oven for 35-40 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean or with a few moist crumbs.

FAQ – FREQUENTLY ASKED QUESTIONS:

Do I need to refrigerate the dough before baking?

No need to refrigerate the dough. These bars bake well right after mixing the ingredients, which saves time.

How do I make the bars more gooey?

For extra gooey bars, underbake them slightly by reducing the bake time by a few minutes. Keep an eye on them to prevent overcooking.

How do I know when the cookie bars are done?

The edges should be golden brown, and a toothpick inserted into the center should come out clean or with a few moist crumbs, but not raw batter.

How do I prevent the bars from being too dry?

Be sure not to overbake them. Check for doneness a few minutes before the recommended bake time and remove them from the oven when they’re just golden around the edges.

PEANUT BUTTER COOKIE BARS RECIPE ADD-INS AND VARIATIONS?

Reese’s Peanut Butter Chips Substitution: Swap the Reese’s peanut butter chips with white chocolate chips, butterscotch chips, or caramel chips for a different flavor combination.
Chocolate Chips Variation: Replace semisweet chocolate chips with milk chocolate, dark chocolate, or even mint chocolate chips to switch up the taste.
Brown Sugar Substitution: Use coconut sugar or maple syrup as a natural alternative to brown sugar, giving the bars a slightly different sweetness profile.
Flour Variation: Make the bars gluten-free by using a gluten-free flour blend, maintaining the chewy texture without the gluten.
Add Mix-ins: Try adding chopped pretzels, crushed graham crackers, or shredded coconut for a unique texture and flavor boost.
Topping Variation: Top the bars with mini M&Ms, crushed Oreos, or a drizzle of melted chocolate for an extra fun and flavorful garnish.

WHAT IS COMMONLY SERVED WITH COOKIE BARS?

Cookie bars are great with a variety of drinks and sides. A cold glass of milk is a classic choice that balances the sweetness. Coffee or hot chocolate also pair well, especially for dessert or a snack. For something lighter, try lemonade, iced tea, or a bubbly soda. You can also serve them with fresh fruit, ice cream, or whipped cream to make the dessert even better.

How should peanut butter cookie bars be stored?

To keep peanut butter cookie bars fresh, store them in an airtight container at room temperature. They’ll stay delicious for up to 5 days this way. If you want them to last a bit longer, you can keep them in the refrigerator, where they’ll stay good for up to a week. Make sure the container is well-sealed to prevent them from drying out or picking up other flavors from the fridge. When you’re ready to enjoy them, just take them out and let them come to room temperature if they’ve been chilled.

CAN THE REESE’S PIECES COOKIE BARS BE FROZEN FOR LATER?

To freeze cookie bars, let them cool completely first. Cut them into pieces, then wrap each piece tightly in plastic wrap or aluminum foil. Put the wrapped bars in a freezer-safe bag or container, and label it with the date. They’re best used within 3 months. When you want to eat them, just take out the amount you need and let them thaw at room temperature for a few hours.
