Step‑by‑Step Instructions for Reese’s Pieces Cookie Bars

Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats, grab a 9x13-inch baking pan and either grease it with butter or line it with parchment paper. This ensures easy removal of your delicious Reese’s Pieces Cookie Bars once they’re baked, so you can savor every bite without fuss.

Step 2: Prepare the Cookie Dough
In a large mixing bowl, combine the yellow cake mix, melted butter, vanilla extract, and room temperature eggs. Use a hand mixer or a sturdy spoon to mix until the ingredients come together into a gooey, smooth dough. This rich blend is the heart of your cookie bars and should take about 2-3 minutes of mixing to achieve the right consistency.

Step 3: Incorporate the Chocolate Chips
Next, gently fold the semi-sweet chocolate chips into the dough by hand. Use a spatula to ensure the chocolate is evenly dispersed without overmixing the batter. This step adds melty pockets of chocolate that will perfectly complement the sweetness of your Reese’s Pieces Cookie Bars.

Step 4: Transfer to the Baking Pan
Carefully spread the cookie dough into your prepared baking pan, using the back of a spatula to press it evenly into the corners. Make sure to create a smooth surface on top as this will help your bars bake evenly. The dough should fill the pan to the edges, creating that thick, chewy texture we all love.

Step 5: Add the Reese’s Pieces
Now it’s time to make the bars pop with color! Sprinkle the Reese’s Pieces candies generously over the top of the dough, pressing them lightly into the mixture. This not only looks fantastic but also ensures that each bite of your cookie bars is adorned with crunchy, peanut-buttery goodness.

Step 6: Bake to Perfection
Place the baking pan in the preheated oven and bake for 20-25 minutes. Look for golden brown edges and a center that’s just set – it should have a slight jiggle when you gently shake the pan. For extra gooey cookie bars, consider taking them out a minute or two early, as they will continue to firm up while cooling.

Step 7: Cool and Slice
Allow your Reese’s Pieces Cookie Bars to cool completely in the pan on a wire rack. This cooling step is crucial to achieve perfect cuts. Once cooled, slice into squares using a sharp knife, and serve these colorful treats to your family and friends!

Storage Tips for Reese’s Pieces Cookie Bars

Room Temperature: Store bars in an airtight container at room temperature for up to 4 days to maintain freshness and texture.

Fridge: If you prefer a chilled treat, place the bars in the fridge. They’ll stay good for up to 1 week, and the flavors will even improve after a day!

Freezer: Freeze individually wrapped bars for up to 3 months. When you're ready to enjoy, let them thaw at room temperature or pop one in the microwave for a few seconds to restore melty goodness.

Reheating: To enjoy a warm snack, microwave for about 10-15 seconds. Just enough to soften and enhance the taste of the Reese’s Pieces Cookie Bars without overdoing it!

• Underbake for Gooeyness: Aim for a slight jiggle in the center of your bars when you take them out of the oven; this ensures a deliciously gooey texture.

Reese’s Pieces Cookie Bars Recipe FAQs

What type of cake mix is best for these bars?
Absolutely! I recommend using a yellow cake mix for the best flavor and texture. However, if you’re looking for a lighter profile, a white or vanilla cake mix works wonderfully as a substitute. Just make sure it’s a good-quality mix for the best results!

How should I store my Reese’s Pieces Cookie Bars?
To keep your bars fresh, store them in an airtight container at room temperature for up to 4 days. If you prefer them chilled, placing them in the fridge is a great option, and they will last for about 1 week. The flavors can even deepen and improve after a day in the refrigerator!

Can I freeze these cookie bars?
Definitely! To freeze, wrap each cookie bar individually in plastic wrap or aluminum foil, then place them in a freezer-safe bag. They can be stored for up to 3 months. When you’re ready to enjoy, let them thaw at room temperature or pop one in the microwave for about 10-15 seconds to restore their melty goodness before serving.

What do I do if my cookie bars are too crumbly?
If your cookie bars turn out crumbly, it could be due to overbaking or not enough wet ingredients. Ensure that you’re taking them out of the oven when they are just set but still have a slight jiggle in the center. For a fudgier texture next time, slightly reduce the baking time to around 20 minutes.

Are these cookie bars suitable for dietary restrictions?
The Reese’s Pieces cookies are vegetarian-friendly but do contain eggs and butter. If anyone in your home has allergies, consider using egg substitutes like flaxseed meal or applesauce. For gluten-free options, feel free to swap the yellow cake mix for a gluten-free variation. Always double-check the candy choice for allergens!

How can I make my bars extra chewy?
For the chewiest results, try the following: use room temperature ingredients, slightly underbake the bars for that gooey quality, and let them cool completely in the pan before cutting. This extra step is crucial for achieving the ideal chewy texture that everyone loves in a cookie bar!
