The first time I made these bars, I was caught in one of those moods where nothing sounded better than something absurdly sweet and warm. It was a rainy Friday, and I found myself staring at a jar of caramel sauce in the fridge, wondering what would happen if I swirled it into cookie dough and THEN frosted the whole thing with more caramel. The result was so outrageously good that my roommate actually texted me from the other room asking what died in the kitchen.
I brought these to a friends holiday cookie exchange last year and they vanished before anyone even touched the decorated sugar cookies. Someone asked me for the recipe three times because they didnt believe me when I said the secret was just really good caramel sauce and patience while melting the butter for the frosting.
Ingredients
- Unsalted butter softened: I cannot stress enough how important room temperature butter is here. Cold butter creates weird lumpy dough and your caramel frosting will seize up into a sad grainy mess
- Light brown sugar packed: This is what gives the cookie base that chewy caramel-like depth. Dont try to substitute granulated sugar your bars will turn out flat and taste like regular chocolate chip cookies
- Semi-sweet chocolate chips: I prefer these over milk chocolate because they stand up to all that caramel sweetness without making the bars overwhelmingly sugary
- Caramel sauce: Use the good stuff here. Homemade caramel is incredible but a high-quality store-bought sauce works perfectly as long as its pourable and not too thick
- Whole milk: For the frosting whole milk creates the richest silkiest consistency. I tried this once with almond milk and the frosting turned thin and slightly grainy
Instructions
- Preheat your oven and prepare the pan:
- Set your oven to 350°F and line a 9x13-inch pan with parchment paper. Leave those edges hanging over the sides like a little sling it makes removing the bars so much easier later.
- Cream the butter and sugars:
- Beat the softened butter brown sugar and granulated sugar until the mixture turns pale and fluffy. This takes about 3 minutes with an electric mixer and creates that perfect chewy texture.
- Add the eggs and vanilla:
- Drop in your eggs one at a time letting each one fully incorporate before adding the next. Then pour in your vanilla and give it another good mix.
- Combine the dry ingredients:
- In a separate bowl whisk together the flour baking soda and salt. Gradually add this to your wet mixture mixing just until you no longer see streaks of flour.
- Fold in the chocolate chips:
- Grab a spatula and gently fold those chocolate chips through the dough. I love finding little pockets of chocolate throughout every bar.
- Layer the dough and caramel:
- Spread half your cookie dough into the prepared pan. Drizzle that caramel sauce all over the dough then drop spoonfuls of the remaining dough on top and gently spread it as best you can.
- Bake until golden:
- Pop this in the oven for 28 to 32 minutes. Youre looking for golden edges and a center that looks set but still slightly soft it will continue cooking as it cools.
- Make the caramel frosting base:
- In a medium saucepan melt that butter over medium heat. Stir in the brown sugar and keep stirring until it completely dissolves then let it gently bubble for exactly 2 minutes.
- Add milk and cool slightly:
- Pour in your milk and bring everything back to a gentle simmer. Remove it from the heat and let it cool for 5 minutes this step is crucial or your powdered sugar will turn to lumpy cement.
- Whisk in powdered sugar:
- Sift in your powdered sugar while whisking constantly. Add the vanilla and salt then keep whisking until you have this gorgeous smooth spreadable frosting.
- Frost and slice:
- Spread that caramel frosting all over your completely cooled bars. Let them set for 15 to 20 minutes before slicing because warm frosting makes a mess of your knife.
These bars became my go-to comfort bake during a particularly stressful month at work. Theres something about the process of swirling caramel into dough and watching the frosting come together that feels like giving yourself a giant edible hug.
Getting That Perfect Caramel Swirl
The trick to getting those pretty caramel ribbons instead of a messy blob is to keep your caramel sauce at room temperature before drizzling. If its too cold it wont spread and if its too hot it sinks straight through to the bottom of the pan.
Storage Secrets
I keep these bars between layers of wax paper in an airtight container. They actually taste better on day two when all those flavors have had time to really get friendly with each other. The texture becomes somehow even more fudgy.
Serving Suggestions
These bars are incredible warmed up for 15 seconds in the microwave with a scoop of vanilla ice cream melting on top. The contrast between hot fudgy cookie and cold creamy ice cream is absolutely unbeatable.
- Sprinkle flaky sea salt over the frosting while its still wet for that salted caramel effect
- Cut them small because these are incredibly rich little squares go a long way
- Stack them in a pretty box lined with parchment paper for the most thoughtful homemade gift
I hope these bars bring as much cozy comfort to your kitchen as they have to mine. Theres something magical about caramel and chocolate together that just makes everything better.
