Candy Bar Cookie Bars Made Stepwise
Let’s get into the fun part—baking these Candy Bar Cookie Bars! Follow these simple steps:
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures the bars will bake evenly.
Step 2: Prepare the Baking Pan
Grease your baking pan with butter or line it with parchment paper for easy removal later on.
Step 3: Mix the Wet Ingredients
In a large mixing bowl, combine 1 cup of brown sugar, 1 cup of softened butter, 1 cup of corn syrup, 1 cup of creamy peanut butter, and 1 teaspoon of vanilla extract. Mix until smooth and creamy.
Step 4: Add the Oats
Stir in 3 cups of quick-cooking rolled oats until fully combined. The oats will give the bars their chewy texture.
Step 5: Fold in the Chocolate and Peanuts
Next, gently fold in 2 cups of semisweet chocolate chips, 1 cup of peanut butter chips, and 1 cup of chopped peanuts until evenly distributed.
Step 6: Spread the Mixture
Transfer the mixture to your prepared baking pan, pressing it down evenly with a spatula. Make sure it is packed tightly for the best results.
Step 7: Bake
Place the pan in the preheated oven and bake for about 25-30 minutes, or until the edges are golden brown and the center is set.
Step 8: Cool and Cut
Once baked, remove the pan from the oven and let it cool completely before cutting it into bars. This will help the bars hold their shape when slicing.

These Candy Bar Cookie Bars are incredibly versatile, making them perfect for any time of year. Here are a few ideas to enjoy them throughout the seasons:
- Fall: Add in chopped apples and cinnamon for a seasonal twist.

- Summer: Top with fresh berries for a refreshing touch.

What I Learned Testing
Through the testing process, I learned a few important tips that can elevate your Candy Bar Cookie Bars:
- Using room temperature butter helps create a smoother mixture.
- Pressing the mixture firmly into the pan results in denser, chewier bars.
- Letting the bars cool completely before cutting prevents them from crumbling.
- Adding a pinch of sea salt on top enhances the chocolate and peanut butter flavors.
These insights can make a significant difference in your baking experience!
Storing, Freezing & Reheating
If you have any leftovers (which is unlikely!), here’s how to store them:
You can store your Candy Bar Cookie Bars in an airtight container at room temperature for up to a week. For longer storage, freeze the bars wrapped tightly in plastic wrap and then foil. They can last in the freezer for up to three months. To reheat, simply pop them in the microwave for a few seconds until warm, or enjoy them chilled straight from the fridge!
Reader Questions
Can I substitute the peanut butter with another nut butter?
Absolutely! Almond butter or sunflower seed butter can be great alternatives if you prefer a different flavor or have allergies to peanuts.
Can I use old-fashioned oats instead of quick-cooking oats?
Yes, but keep in mind that the texture may be a bit chewier. You may need to adjust the baking time slightly.
Can I make these bars gluten-free?
Yes! Simply use certified gluten-free oats to ensure that the bars are gluten-free.
How do I know when the bars are done baking?
The edges should be golden brown, and the center should feel set to the touch. A toothpick inserted in the center should come out clean or with a few moist crumbs.
