Chocolate chip caramel butter bars sandwich a thick caramel layer between two portions of rich chocolate-chip cookie dough. Flour whisked into prepared caramel sauce gives the center enough body to set, while open patches between the top dollops reveal the filling.
The 9-by-13-inch pan makes 24 bars in about one hour, plus complete cooling. The dough is intentionally stiff so it can support the caramel without collapsing.
Ingredients for Chocolate Chip Caramel Butter Bars
The cookie dough uses 1 1/2 cups softened salted butter, 1 1/2 cups sugar, 2 large eggs, 1 tablespoon vanilla, 1 teaspoon baking soda, 1 teaspoon cream of tartar, 4 cups all-purpose flour, and 2 cups chocolate chips.
For the center, whisk one 11-ounce jar caramel sauce with 1/4 cup all-purpose flour.

How to Make Chocolate Chip Caramel Butter Bars
- Prepare. Heat the oven to 350°F and spray a 9-by-13-inch dish.
- Cream. Beat softened butter and sugar until fluffy.
- Add wet ingredients. Mix in eggs and vanilla, followed by baking soda and cream of tartar.
- Add flour. Mix it in gradually just until no white streaks remain.
- Fold in chips. Stir chocolate chips into the stiff dough by hand.
- Make caramel filling. Whisk caramel sauce with 1/4 cup flour until smooth.
- Layer. Press half the dough over the bottom and slightly up the sides, pour in caramel, and dollop remaining dough over it.
- Bake and cool. Bake 25 to 35 minutes until golden and cool completely before cutting.

Use Fully Softened Butter
Let the salted butter soften to room temperature until it yields to gentle pressure but remains solid. Beat it with the sugar until the mixture is lighter and fluffy, scraping the bowl as needed.
Cold butter does not aerate evenly, while melted butter makes the dough greasy and changes how the bars spread. Properly softened butter creates the intended tender cookie texture.

Mix the Eggs and Leaveners Evenly
Beat in the eggs and tablespoon of vanilla until the mixture is uniform. Add the baking soda and cream of tartar and mix well before most of the flour enters the bowl.
Distributing the leaveners at this stage reduces the chance of bitter concentrated pockets. Scrape the sides and bottom so every part of the dough rises consistently.
Add Flour Gradually
Mix in the flour a little at a time on low speed. Stop as soon as the last white streak disappears. Overmixing develops gluten and can make the baked base hard.
The mixer may strain as the dough thickens, so finish the last addition with a sturdy spoon if necessary. Fold in the chocolate chips by hand for even distribution.
Thicken Prepared Caramel with Flour
Whisk the jar of caramel sauce with 1/4 cup flour in a separate bowl. Continue until there are no dry lumps and the mixture looks smooth and slightly thicker.
The added flour helps the caramel set during baking and cooling. Without it, much of the center may run out when warm bars are cut.
Press the Bottom Layer Up the Sides
Divide the cookie dough roughly in half. Press one portion across the sprayed pan and about halfway up the sides, forming a shallow shell around the caramel.
Lightly coating clean hands with nonstick spray makes the stiff dough easier to press. Keep the bottom thickness even, especially in the corners.
Pour and Contain the Caramel
Pour the thickened caramel over the dough and spread it level without pushing it above the raised edge. Leaving a narrow dough border reduces leaks and burnt sugar against the pan.
Drop spoonfuls of remaining dough over the caramel. Complete coverage is unnecessary; the dollops spread as they bake and create an appealing broken top.
Bake Until Golden, Not Hard
Bake at 350°F for 25 to 35 minutes. The top dough should be golden and set, while caramel may still bubble through the openings. Begin checking at the lower end because pan material affects browning.
Do not wait for the caramel center to become firm in the oven. It thickens considerably as the pan cools.
Cool Completely Before Cutting
Place the pan on a rack and allow it to cool fully. Cutting while warm releases liquid caramel and compresses the soft cookie layers.
Once set, use a sharp knife to cut six columns by four rows for 24 bars. Wipe the blade between cuts if caramel begins to cling.
Troubleshooting
- Dough feels too stiff: This is expected; finish folding with a sturdy spoon.
- Caramel runs: Whisk in the measured flour and cool completely.
- Bottom is uneven: Distribute small dough pieces across the pan before pressing.
- Edges darken early: Use a light-colored pan or cover the perimeter loosely with foil.
- Bars are hard: Stop baking once the top is golden and avoid overmixing flour.
Serving, Cutting, and Storage
Serve at room temperature for a soft center, or chill briefly for firmer, cleaner squares. Because these bars are rich, the 24-piece yield creates a satisfying portion. A small offset spatula helps lift the first bar without cracking the surrounding pieces. For a tidy platter, arrange the bars in a single layer.
Store airtight at room temperature for up to 3 days or refrigerate for up to 1 week. Separate stacked layers with parchment. Let refrigerated bars stand before serving so the caramel softens.
Freezing and Make-Ahead Notes
Freeze cooled individual bars in an airtight container for up to 2 months, separated with parchment. Thaw inside the closed container at room temperature.
The full pan can be baked one day before serving. Cool completely, cover, and cut the next day. Avoid refrigerating the raw layered dough because caramel can seep into the base during a long wait.
Conclusion
Make a stiff chocolate-chip cookie dough. Whisk jarred caramel sauce with flour. Press half the dough into a sprayed 9-by-13-inch pan and up the sides, add caramel, and dollop remaining dough on top. Bake at 350°F for 25 to 35 minutes and cool completely before cutting.
Frequently Asked Questions
- → Why is flour added to caramel sauce?
It thickens the caramel so the center sets instead of running from the cooled bars.
- → Should the cookie dough be very stiff?
Yes. The firm dough supports the caramel and is best finished by hand with a sturdy spoon.
- → How do I know when the bars are done?
The top dough should look set and golden, while caramel may still bubble through open patches.
- → Can caramel butter bars be frozen?
Yes. Freeze cooled bars airtight for up to 2 months.
