Salted Caramel Oatmeal Cookie Bars Recipe – Best Gooey Homemade Treats

The first time I pulled a pan of salted caramel oatmeal cookie bars out of the oven, my kitchen smelled like a cross between a cozy bakery and a caramel factory. There’s something magical about gooey caramel mingling with chewy oats—the kind of treat that makes you want to sneak just one more square long after dessert is over. Honestly, these bars have become my go-to for potlucks, holiday trays, and even those “I need something sweet ASAP” evenings.

I stumbled onto the idea for these salted caramel oatmeal cookie bars during a late-night baking session with my kids. We’d planned on classic oatmeal cookies but someone (okay, it was me) forgot to soften the butter. So, we pressed the dough into a pan, added a layer of caramel candies I found hiding in the pantry, and sprinkled a bit of flaky salt on top. The result? Pure, gooey, salty-sweet bliss that’s now a staple in our home.

What I love most about this recipe is its versatility and reliability. Whether you’re baking for a crowd, prepping ahead for a busy week, or just craving something homemade, these bars deliver every single time. Plus, with wholesome oats, a buttery cookie base, and that irresistible salted caramel layer, they strike the perfect balance between comfort food and wow-factor dessert.

I’ve tested them more times than I care to admit, and let’s just say—there’s never a crumb left behind.

What sets these salted caramel oatmeal cookie bars apart is the technique: I blend a portion of the oats for a tender bite, then use both brown sugar and white sugar for depth and chewiness. The caramel layer is made with real caramel candies and a splash of cream, so it’s gooey but holds its shape. And that pinch of flaky salt? Game-changer.

What Ingredients You Will Need

This recipe leans on classic pantry staples with a few little upgrades to make each bite extra special. You’ll find everything you need at your regular grocery store, and I’ll share a few of my favorite brands and swaps below.

• For the Oatmeal Cookie Layer:
  • 1 cup (226g) unsalted butter, softened (adds richness and a tender bite)
  • 1 cup (200g) light brown sugar, packed (for chewiness and caramel notes)
  • 1/2 cup (100g) granulated sugar (balances sweetness)
  • 2 large eggs, room temperature (binds everything together)
  • 2 teaspoons vanilla extract (I love Nielsen-Massey for a bold vanilla flavor)
  • 1 1/2 cups (190g) all-purpose flour (King Arthur works great)
  • 2 1/2 cups (225g) old-fashioned rolled oats (for that classic, rustic texture)
  • 1 teaspoon baking soda (for lift)
  • 3/4 teaspoon fine sea salt (balances all the sweetness)
• For the Salted Caramel Filling:
  • 11 ounces (311g) soft caramel candies, unwrapped (like Kraft or Werther’s—just not the hard ones)
  • 1/4 cup (60ml) heavy cream (makes the caramel pourable and creamy)
  • 1/2 teaspoon coarse or flaky sea salt (Maldon is my go-to for finishing salt)

Ingredient Tips & Substitutions:

• If you want to make these gluten-free, swap the all-purpose flour for a 1:1 gluten-free blend and make sure your oats are certified gluten-free.
• No heavy cream? You can use half-and-half or even whole milk, but the caramel layer might be slightly less rich.
• For a dairy-free version, use vegan butter and coconut cream in place of the butter and cream. The texture will change slightly, but they’re still delicious.
• Don’t skip the salt! That sprinkle on top makes the flavors pop. If you only have table salt, use half the amount for the final sprinkle.
• Want a chocolatey twist? Add 1 cup (170g) of chocolate chips or chunks between the layers.

I’ve tried making these bars with both quick oats and old-fashioned oats; old-fashioned gives the best chewy texture, while quick oats make the bars softer and more cakey. If you love nuts, toss in 1/2 cup (60g) of chopped pecans or walnuts for extra crunch (my dad’s favorite variation). And if you’re feeling fancy, swap a tablespoon of flour for cocoa powder for a subtle chocolate undertone.

Equipment Needed

• 9×13-inch (23x33cm) baking pan: Metal or glass both work (I use metal for crispier edges, glass for softer bars). If you only have a smaller pan, just bake a little longer and expect thicker bars.
• Large mixing bowls: At least two—one for the wet ingredients, one for the dry. I love my stainless steel bowls (easy clean-up, lightweight).
• Hand mixer or stand mixer: If you don’t have one, a sturdy wooden spoon and elbow grease will do the trick. I’ve made these both ways!
• Microwave-safe bowl or small saucepan: For melting the caramel and cream together. If using the stove, keep the heat low and stir often to avoid burning.
• Parchment paper or non-stick spray: Makes it way easier to lift the bars out and slice cleanly. Trust me, you don’t want to skip this step.
• Offset spatula or the back of a spoon: For spreading dough and caramel evenly.
• Sharp knife: For slicing (a bench scraper also works well for neat squares).

No need for fancy tools here—just the basics most home bakers already have. If you’re on a budget, dollar store bowls and pans work just fine (I’ve used them for years). For specialty equipment, keep everything dry after washing to prevent rust. And if you don’t have parchment, line the pan with foil and grease it well.

Preparation Method

1. Prep the Pan: Preheat your oven to 350°F (175°C). Line a 9×13-inch (23x33cm) baking pan with parchment paper, leaving extra overhang on the sides for easy lifting. Lightly coat with non-stick spray for insurance. (This helps prevent sticking—trust me, caramel can be stubborn!)
2. Mix Dry Ingredients: In a large bowl, whisk together 1 1/2 cups (190g) all-purpose flour, 2 1/2 cups (225g) old-fashioned rolled oats, 1 teaspoon baking soda, and 3/4 teaspoon fine sea salt. Set aside.
3. Cream Butter and Sugars: In another large bowl, beat 1 cup (226g) softened unsalted butter with 1 cup (200g) packed light brown sugar and 1/2 cup (100g) granulated sugar. Use a hand mixer or stand mixer on medium speed for about 2 minutes, until light and fluffy. (If mixing by hand, beat vigorously until well combined.)
4. Add Eggs and Vanilla: Add 2 large eggs, one at a time, mixing well after each addition. Pour in 2 teaspoons vanilla extract. Beat until fully incorporated. (Mixture should look creamy and light.)
5. Combine Wet and Dry: Add dry ingredients to the wet mixture in two batches. Mix on low until just combined—don’t overmix, or the bars can be tough. Scrape down the sides as needed. The dough will be thick and a bit sticky.
6. Layer the Dough: Scoop about 2/3 of the dough into your prepared pan. Press it evenly into the bottom using your hands, a spatula, or the back of a spoon. (Tip: Lightly wet your hands if the dough is sticking.)
7. Make the Caramel Layer: In a microwave-safe bowl, combine 11 ounces (311g) unwrapped soft caramel candies and 1/4 cup (60ml) heavy cream. Microwave in 30-second intervals, stirring between each, until smooth (about 2 minutes total). Alternatively, melt gently in a saucepan over low heat, stirring constantly. (Watch closely—caramel burns fast!)
8. Pour and Sprinkle: Pour the melted caramel evenly over the bottom cookie layer. Use an offset spatula to spread edge-to-edge. Immediately sprinkle 1/2 teaspoon flaky sea salt over the caramel (if you love salty-sweet, add a pinch more).
9. Add the Top Layer: Dollop the remaining dough in small spoonfuls over the caramel layer. Gently press and spread to cover as much of the caramel as possible—some caramel peeking through is perfect. (It’ll spread while baking.)
10. Bake: Place pan on the center rack and bake for 28-32 minutes, until the top is golden brown and the edges are set. The middle may look slightly soft—that’s good! It will set as it cools.
11. Cool and Slice: Allow bars to cool in the pan for at least 1 hour (if you rush, the caramel will ooze everywhere). For clean cuts, chill in the refrigerator for 30 minutes before lifting out and slicing into squares.
12. Serve or Store: Enjoy slightly warm for maximum gooeyness, or let them cool completely for neater bars. Store leftovers tightly covered at room temperature for up to 3 days, or freeze for later.

Troubleshooting Tips: If your caramel seems too thick to pour, add an extra splash of cream and reheat gently. If you overbake, bars will be more firm but still tasty—just serve with a scoop of ice cream!

Cooking Tips & Techniques

Over the years, I’ve picked up a handful of tricks that guarantee perfect salted caramel oatmeal cookie bars every time:

• Don’t Overmix: After adding the dry ingredients, mix just until combined. Overmixing can make the bars dense instead of chewy.
• Even Layers Matter: Press the bottom layer firmly so the caramel doesn’t seep to the bottom and stick. If the dough is sticky, use damp hands or a piece of parchment paper to press it down.
• Caramel Consistency: Melt the caramel candies and cream slowly—rushing this can cause it to seize or burn. Stir gently until just smooth.
• Salt Timing: Sprinkle the flaky salt immediately after pouring the caramel, so it sticks and doesn’t fall off later.
• Watch the Bake Time: Set a timer! Overbaking will make the bars dry and crumbly. The center should look just set but still soft when you pull them out.

I’ll admit, I once tried to slice the bars straight from the oven (impatience got the better of me). Huge mistake—the caramel was molten and ran everywhere! Now, I always let them cool and chill a bit for perfect slices. If you’re multitasking in the kitchen, prep the caramel layer while the bottom bakes for a few minutes, but don’t walk away from melting caramel—it needs your attention.

Consistency is key: Use a kitchen scale for flour and oats if you have one. This small step can make a world of difference, especially if you bake often. And if you’re baking for a party, double the recipe and use two pans—these bars go fast!

Variations & Adaptations

There’s no one right way to enjoy salted caramel oatmeal cookie bars, and honestly, I’ve had a blast experimenting with different twists. Here are some of my favorite variations:

• Gluten-Free: Swap in a 1:1 gluten-free flour blend and make sure your oats are certified gluten-free. The bars are just as chewy and delicious!
• Nutty Caramel Bars: Add 1/2 cup (60g) chopped pecans or walnuts to the dough for crunch and flavor. Sometimes I toast the nuts first for extra depth.
• Chocolate Caramel Oat Bars: Sprinkle 1 cup (170g) mini chocolate chips or chopped dark chocolate between the oatmeal and caramel layers. The chocolate melts into the caramel—pure decadence!

For a fall twist, stir in 1 teaspoon of cinnamon and a pinch of nutmeg to the oatmeal dough. Or, if you’re baking in the summer, swap the caramel for a layer of raspberry or strawberry jam (it’s surprisingly good!).

If you’re making these for someone with dairy allergies, I’ve had success using vegan buttery sticks and coconut cream in the caramel. The texture is slightly different but still gooey and satisfying.

One of my favorite personal tweaks: adding a layer of sliced bananas under the caramel for a banoffee-inspired treat. My kids love it, and it’s a fun way to use up ripe bananas.

Serving & Storage Suggestions

These salted caramel oatmeal cookie bars are best served at room temperature or slightly warm—just enough so the caramel is gooey but not runny. For parties, I cut them into small squares and pile them on a rustic wooden board for that Pinterest-perfect look.

Pair with a scoop of vanilla ice cream, a dollop of whipped cream, or even a drizzle of melted chocolate for extra indulgence. They also go great with a cup of strong coffee or an ice-cold glass of milk.

• Room Temperature: Store in an airtight container for up to 3 days. The texture stays chewy and the caramel stays soft.
• Refrigerator: If your kitchen is warm, refrigerate for up to 5 days. Let bars sit at room temp for 10-15 minutes before serving for best texture.
• Freezer: Freeze sliced bars (separated with parchment) in a zip-top bag for up to 2 months. Thaw at room temp or zap in the microwave for 10-15 seconds for gooey goodness.

Over time, the flavors meld and the oatmeal gets even chewier—a happy accident if you ask me. If you’re prepping ahead, these bars are a lifesaver for busy weeks or last-minute guests.

Nutritional Information & Benefits

Each salted caramel oatmeal cookie bar packs about 240 calories, 11g fat, 35g carbs, and 3g protein (estimated—depends on portion size). While they’re definitely a treat, the oats add fiber and a bit of protein, making them more satisfying than your average dessert bar.

Oats are a great source of whole grains and have been shown to help with heart health and digestion. If you use gluten-free oats and a flour blend, these can fit into a gluten-free diet. Watch for allergens: these bars contain dairy, eggs, and (potentially) nuts depending on your mix-ins.

From a wellness perspective, I love that these bars offer both comfort and a bit of nutrition from the oats. They’re not “health food,” but they’re more wholesome than a lot of store-bought treats. And hey, sometimes a little sweetness is good for the soul!

Conclusion

If you’re searching for an easy, crowd-pleasing dessert that brings together gooey caramel, chewy oats, and that perfect hint of salt, these salted caramel oatmeal cookie bars are calling your name. They’re the kind of treat that turns any day into a special occasion—and they’re always a hit, whether you’re baking for family or friends.

Don’t be afraid to make these your own—try new mix-ins, play with the layers, or adjust the salt to your taste. That’s half the fun of baking at home! Personally, I love how each batch turns out just a little different, but always delicious.

If you try these, I’d love to hear what you think—share your experience in the comments, let me know your favorite variation, or tag me on social media with your creations. Happy baking, and may your bars always be gooey and your caramel perfectly salted!
