The Method for Candy Bar Cookie Bars

Now, let’s get baking! Follow these simple steps to create your Candy Bar Cookie Bars.
Step 1: Prepare Your Oven and Baking Dish
Preheat your oven to 350°F (175°C). Grease your 9×13 inch baking dish or line it with parchment paper for easy removal later.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, combine the softened butter, firmly packed brown sugar, corn syrup, creamy peanut butter, and vanilla extract. Use an electric mixer or a whisk to blend until the mixture is smooth and creamy.
Step 3: Add the Oats
Gradually add the quick-cooking rolled oats to the wet mixture. Stir well until the oats are fully incorporated and the mixture is thick and sticky.
Step 4: Fold in the Chocolate and Peanut Butter Chips
Gently fold in the semisweet chocolate chips and peanut butter chips until evenly distributed throughout the oat mixture.
Step 5: Spread in Baking Dish
Pour the mixture into the prepared baking dish. Using a spatula, spread it evenly across the bottom, pressing it down firmly to create a compact layer.
Step 6: Bake to Perfection
Place the baking dish in the preheated oven and bake for 20-25 minutes, or until the edges are golden brown. The center may still look slightly soft, which is perfect for chewy bars!
Step 7: Prepare the Topping
While the bars are baking, prepare the topping by melting the additional creamy peanut butter and semisweet chocolate chips in a microwave-safe bowl. Heat in 30-second intervals, stirring in between, until smooth.
Step 8: Add the Topping
Once the cookie bars are out of the oven, spread the melted peanut butter and chocolate mixture over the top. Sprinkle with chopped peanuts and any additional peanut butter chips or chocolate chips, pressing them down gently into the warm topping.
Step 9: Cool and Serve
Allow the Candy Bar Cookie Bars to cool in the baking dish for at least 30 minutes before slicing into squares. For best results, refrigerate for a couple of hours to set the chocolate and peanut butter topping.
Allergy-Friendly Substitutes

If you have any allergies or dietary preferences, consider these substitutes:
- Dairy-free butter: Use a dairy-free alternative for a vegan version.
- Maple syrup: Substitute corn syrup with maple syrup for a natural sweetener.
- Gluten-free oats: Ensure your oats are certified gluten-free if necessary.

Troubleshooting Q&A
What if my bars are too crumbly?
If your Candy Bar Cookie Bars turn out crumbly, it may be due to insufficient binding ingredients. Ensure you measure the peanut butter and butter accurately, as they help create a chewy texture.
Why are my bars too sticky?
Bars can be sticky if they are underbaked. Ensure you bake them until the edges are golden brown and the center is set. If they are still too sticky after cooling, you may want to refrigerate them to firm up.
Can I use different types of chocolate?
Absolutely! Feel free to experiment with different types of chocolate such as dark chocolate or white chocolate chips for a unique flavor twist.
How do I know when my bars are done baking?
The bars are done when the edges appear golden brown and the center is slightly soft but not wet. They will continue to firm up as they cool.
