There are days when a simple chocolate chip cookie just doesn’t cut it. You know those days? When you’re craving something with a little more oomph. Something sweet, but also salty. Chewy, yet a little gooey. It’s a tall order.
I found myself in that exact spot last Tuesday. I wanted it all, and I wasn’t willing to compromise. That’s how these Salted Caramel Chocolate Chip Oat Cookie Bars were born. They are the perfect storm of flavors and textures.
Imagine a buttery, chewy oat cookie base, studded with rich chocolate chips. Now, picture a thick layer of homemade, velvety caramel poured over the top. To finish it off, a generous sprinkle of flaky sea salt cuts through the sweetness, making every bite an absolute dream. This isn’t just a dessert; it’s an experience.
What You’ll Need
Before we dive in, let’s get our ingredients in order. I’ve split them into two parts: the oat cookie base and that glorious salted caramel. Having everything measured and ready to go makes the whole process feel like a breeze.
For the Oat Cookie Base:
- 1 cup (2 sticks) unsalted butter, melted
- 1 cup packed light brown sugar
- 1/2 cup granulated sugar
- 2 large eggs
- 1 tablespoon vanilla extract
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 3 cups old-fashioned rolled oats
- 1 1/2 cups semi-sweet chocolate chips
For the Salted Caramel Layer:
- 1 cup (2 sticks) unsalted butter
- 1 cup packed light brown sugar
- 1/2 cup light corn syrup
- 1 (14-ounce) can sweetened condensed milk
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
- 1 to 2 teaspoons flaky sea salt, for sprinkling
Tools Required
You don’t need any fancy gadgets for this recipe. Here’s a quick list of the kitchen tools that will make this job easier.
- 9×13-inch baking pan
- Parchment paper
- Large mixing bowl
- Medium saucepan
- Whisk
- Spatula or wooden spoon
- Measuring cups and spoons
- Candy thermometer (optional, but very helpful!)
Pro Tips
Over the years, I’ve made my fair share of baking mistakes. These little tips will help you sidestep the common pitfalls and get straight to perfectly chewy, gooey bars every single time.
- Don’t Overbake the Base. The key to a chewy cookie bar is to pull it from the oven when it’s just right. You’re looking for the edges to be golden brown, but the center should still look a little soft. It will continue to cook as it cools, giving you that perfect texture.
- Patience with the Caramel. Making caramel can feel intimidating, but the secret is constant, gentle stirring. Don’t crank up the heat to speed things up. A steady, medium heat prevents the sugar from burning and ensures a smooth, creamy result. If you don’t have a candy thermometer, use the “soft-ball stage” test: drop a tiny bit of caramel into a glass of cold water. If it forms a soft, pliable ball, it’s ready.
- Cool Completely. Seriously. I know how tempting it is to slice into these bars the second they seem cool. Trust me on this one: wait. Letting them cool completely in the pan, and even chilling them in the fridge for 30 minutes, is the secret to clean, beautiful squares that don’t fall apart.
- Use Parchment Paper with Overhang. Line your baking pan with parchment paper, leaving a few inches of overhang on two sides. This creates “handles” that let you lift the entire slab of bars out of the pan easily once they’re cool. No more digging out that first tricky piece!
How to Make Salted Caramel Chocolate Chip Oat Bars
Alright, let’s get to the fun part. Follow these steps, and you’ll be on your way to dessert heaven.
Part 1: The Oat Cookie Base
Step 1: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides to lift the bars out later. Lightly grease the paper and any exposed parts of the pan.
Step 2: In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until well combined. Add the eggs one at a time, followed by the vanilla extract, mixing well after each addition.
Step 3: In a separate bowl, stir together the all-purpose flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.
Step 4: Gently fold in the rolled oats and the chocolate chips using a spatula. The dough will be thick and sticky.
Step 5: Press the dough evenly into the bottom of your prepared baking pan. An offset spatula or the bottom of a greased measuring cup works great for this. Bake for 15-18 minutes, or until the edges are lightly golden. Let it cool slightly while you prepare the caramel.
Part 2: The Salted Caramel Layer
Step 1: In a medium, heavy-bottomed saucepan, combine the butter, brown sugar, corn syrup, sweetened condensed milk, and salt.
Step 2: Cook over medium heat, stirring constantly with a whisk or heatproof spatula. It’s important to keep stirring to prevent the bottom from scorching.
Step 3: Bring the mixture to a boil, still stirring. Once it’s boiling, continue to cook for 5-7 minutes, stirring the whole time, until the caramel thickens. If using a candy thermometer, it should read between 235-240°F (112-115°C).
Step 4: Remove the saucepan from the heat and immediately stir in the vanilla extract. Be careful, as it may bubble up.
Step 5: Pour the hot caramel evenly over the partially baked oat cookie base. Use a spatula to spread it to the edges.
Step 6: Sprinkle the top with the flaky sea salt. Don’t be shy!
Part 3: Cooling and Cutting
Step 1: Let the bars cool completely at room temperature for at least 4 hours. This is the hardest part, but it’s crucial for the caramel to set properly. To speed it up, you can place them in the refrigerator for about 2 hours after they’ve cooled a bit on the counter.
Step 2: Once fully set, use the parchment paper handles to lift the entire slab out of the pan. Place it on a cutting board and use a large, sharp knife to cut into bars. Wiping the knife with a damp cloth between cuts helps create clean edges.

Pairing Suggestions
These bars are rich, so they pair wonderfully with simple beverages that balance their sweetness. Try them with:
- A cold glass of milk
- A hot cup of black coffee or a latte
- A simple scoop of vanilla bean ice cream on the side
Leftovers and Storage
If you somehow have leftovers, here’s the best way to keep them tasting fresh.
Room Temperature: Store the bars in an airtight container at room temperature for up to 3 days. Placing a sheet of wax paper between layers prevents them from sticking together.
Refrigerator: For a chewier texture and longer shelf life, you can store them in an airtight container in the fridge for up to a week.
Freezing: These bars freeze beautifully! Cut them into individual squares, wrap each one tightly in plastic wrap, and then place them in a freezer-safe bag or container. They will last for up to 3 months. Let them thaw at room temperature for an hour before enjoying.
Frequently Asked Questions
Q1. My caramel layer is too runny and didn’t set. What happened?
Ans: This usually means the caramel wasn’t cooked long enough or didn’t reach the right temperature (the “soft-ball stage”). Next time, let it boil for the full 5-7 minutes, stirring constantly, or until it visibly thickens. A candy thermometer is your best friend here!
Q2. Can I use quick-cooking oats instead of old-fashioned rolled oats?
Ans: You can, but it will change the texture. Quick oats are thinner and will result in a denser, less chewy base. For that classic cookie-like chew, stick with old-fashioned rolled oats if you can.
Q3. Why are my bars crumbly and falling apart?
Ans: This often comes down to two things: not pressing the base down firmly enough in the pan, or cutting into them before they are completely cool. The cooling step is what allows the caramel to act as a “glue” and hold everything together.
Q4. Can I make this recipe in a smaller pan, like an 8×8 or 9×9?
Ans: Yes, you can! The bars will be much thicker, which means you’ll need to increase the baking time for both the base and the final product. Start by adding 5-10 minutes to the base baking time and watch it closely.
Wrapping Up
There you have it—a dessert that truly covers all the bases. Chewy, sweet, salty, and loaded with chocolate and caramel. It’s the kind of treat that makes an ordinary day feel special.
